Product Development

user requirement specification of Equipment

User Requirement Specification is a specific document where end user generally defines needs, target, goal and their expectation for a system, service and product. This is actually blueprint for the development personnel and it help to ensure that the product meet the target for the specific group.

A standard User Requirement Specification includes information about the user group, targeted use of the product, functional requirements, Operational requirements, and performance requirements. It also contains constraints or limitations.

A standard User Requirement establishes a better understanding between the stakeholders regarding a defined outcome; also sets a specific goal for the end-user and helps to save the project, and product delivery time the best thing is its budget-friendly; the user can previously estimate the cost of the specific project.

URS is generally developed by the buyer defining all listed requirements. After the development of a URS, the user sent it to the equipment manufacturer to prepare it as per predefined criteria.

A poorly developed URS is always creating confusion for the manufacturer, you can see the poorly written URS at the manufacturer’s end and If you don’t know how to write URS then you can ask standard URS template from the manufacturer, they are happy to help you. If supplied Template is found near your requirements then you can go with a modified version.

User Requirement Specification when disregarded?

A confusing URS is always disregarded. If the manufacturer can’t read you then the faulty or wrong machine can be developed which can destroy your project and A meaningful and well-written user requirement specification saves time and money; also reduce misunderstanding among the manufacturer.

A series of emails may generate to explain your requirement to the manufacturer which may express your poor level of understanding of the specific requirement also create of the high chance of wrong specification delivery and You have to express the requirement what exactly you are looking for in your User Requirement Specification (URS).

Keep it simple, Specific, and Better user requirement specification creates better outcomes.

Requirements of user and support design, qualification activities, operations, commissioning, and maintenance are mainly present on the URS. It’s good to set your mind at the start of your dream project.

According to Mark R. Smith, MD, Realtech,

“A standard URS shall be clear, jargon-free, easily readable, not hard to understand which helps to software engineer and Designer clearly readable and understandable of the user requirement with minimum cost and maximum output”.

Types of Requirements

There are several types of requirements that are depicted here.
[] Business Requirements
[] Functional Requirements
[] Stakeholder Requirements
[] Non-Functional Requirements
[] Transition Requirements

What thing to consider for user requirement specification (URS)?
Two main things shall be considered during the writing of URS, number one: What shall be included and number two what shall not be included.

What to include:

During the writing of the URS, the actual information shall be included in the URS. More information may require for big projects and less for a small project the basic of all URS shall be specific. Unknowingly including a feature that is not available in the market is the same as knowingly ruining your project.

Knowing then any feature should be included in the URS. The most important thing is to include only those specifications that are necessary. Features that will never be used need not be included but the facility to use updated features can be retained.

What not to include:

Ambiguous words or terms, Features that are not easy to understand, and that no one has yet used, features that are not user-friendly and will never be used, and features that are overpriced but less important shall be avoided.

How to proceed with your User Requirement Specification?

Before proceeding with your URS, define the responsibility of the stakeholders in your URS then collect all stakeholders’ signatures with designation and date. An approved URS shall be procced to the manufacturer to avoid any wanted circumstances. To sign a document means that you are responsible for it.

What should be included in the Introduction section?

In this section, you should describe more briefly about yourself and why this URS has been raised. Give a short description of your organization. Like “We are Startech is a startup organization in west Virginia. We want to install a high tech tablet compression machine to produce almost 6000K tablets per hour. This user requirement specification (URS) documents the user requirements for producing tablet dosage forms in a tablet compression machine.

The objective of the User Requirement Specification

They clearly describe the goal of the project so that anyone understands it. A brief overview of the project shall be included. Mention the actual purpose of the URS.

Who will write the User Requirement Specification?

Anyone can write URS, who has a thorough knowledge of the system, service, product, or machine in question. But you don’t let someone write something they don’t know about, for example, production personnel can’t write the URS of quality control equipment and vice versa.

How to document a User Requirement Specification?

The user will prepare the URS and another SEM will check the URS and Engineering personnel and the head of the user department will Review the document, finally Head of Quality will approve the URS. Always documented hierarchy shall be maintained.

Which things to follow to write a Modern User Requirement Specification?

From the discussion till now we know what to add to our URS and what not to add. Ambiguity to be avoided as much as possible should be written clearly so that anyone who reads it can understand it. Ambiguity is the enemy of any project’s success and expressing yourself as accurately as possible is possible. Communication must be done in an unambiguous manner to achieve good results; Your project will be successful when you are able to convey your message to others.

To write a best User Requirement Specification you need to keep the following points in mind:

user requirement specification
user requirement specification

1. Focus on Single Requirement:

Check each requirement to be developed and how it is tested. Project success depends on each effective requirement which is really a demand to the project. Avoid unnecessary requirements which really not essential to the project.

2. Avoid Haziness

Your URS must be clearly written. Use a Simple Sentence. No confusing word. Just say what you want and what not.

A user requirement specification should be clearly written, using simple sentences, and without ambiguity. Examples of ambiguous words are:

[] Easy
[] Strong
[] Improve
[] Fast
[] Slow
[] Enough
[] User friendly

What exactly are you meaning “Fast”? this term is theoretical; you can’t actually express your requirement using the word “Fast”. It is hard to measure. Avoid any abbreviations, acronyms, and jargon words (words and phrases, that are not generally understood).

3. Go with the SMART Approach

[] S for Specific
[] M for Measurable
[] A for Achievable
[] R for Realistic
[] T for Time-bound

SMART [Specific, Measurable, Achievable, Realistic, Time-bound) targets offer a decent way to confirm your URS is well-defined and supportable.
Specific: All requirements mentioned in the URS must be specific, clear, and jargon-word-free. Don’t add any unnecessary requirements like easy and fast. Mention the actual specification.

Measurable: Reequipment must be measurable, don’t state anything which can’t confirm by testing or examination. Always avoid theoretical statements like rapid and swift. It can’t measure, you can’t prove that your requirements just met the specification until it is measurable.

Achievable: Never set a requirement which is can’t achieve with help of current technology. A feasibility study shall be done before setting any requirements. You can’t set any requirement which is technically impossible to achieve. It is wise to study well before adding features that you have no idea about. If even then you cannot be confirmed, then seek an expert for help. It is not right to add any feature without knowing it.

Realistic: It’s important to be realistic when determining the list of requirements. Sometimes technically achievable requirements may not be realistic due to regulatory requirements, time restrictions, Budget constraints, or other limitations.

Time-bound: A specific time frame shall be fixed to obtain your project. Even after finishing everything and if the specified time is not fixed, then any project may fail.

4. Organize

Organize your word choice and think carefully about it. Generally, the word “Shall” and “will” define the actual requirement which must be met. Word like “May” and “Could” use to define goals than are expected but not necessarily requirements. So, when you want the requirement must be met then use shall/will and use may/could for not mandatory cases.

5. Control Changes to the Requirements

Any type of changes may require during creating your list of requirements. Changes to the specification of the specific requirement shall be controlled. If any type of change directly affects the requirement, then the requirement shall be updated and a new version shall be created.

6. Requirements Must be Testable

Requirements shall be written in a such way that they can be tested and Specific requirements shall be traceable through the life cycle of the system/service/equipment/instruments.

7. Structural Products

Two types of products may be used as structural products & custom applications; for custom applications, the manufacturer must describe every process step to the user. For structural products, the process steps must be aligned with their predefined specification.

8. Vendor Audit

Most of the cases Regulated companies are most aware of their vendor for periodic assessment. All types of assessment/re-assessment perform in accordance with the Quality Management System (QMS).

9. Specifications

It is essential for the supplier to thoroughly document both the functionality and design of the system which is a prerequisite to ensure successful product development. Documentation must cover all aspects of the system, including software, hardware, and configuration, to meet all requirements to be established.

10. Training & Documentation

The supplier must agree to provide comprehensive system management documentation and provide instructions for both maintenance and use by the supplier and related issues must be agreed upon prior to system purchase.

11. Eliminate Requirement Redundancy

Avoid overcomplicating the system requirements and there is no need to bulk it up by duplicating it. Avoid duplication. Duplicating your documents may require more testing, documentation, and review time, making the project and time progressively longer Don’t include anything which is related to money or finance.

What is the difference between data and information

12. Embrace the Opportunity to Evaluate Vendors

Conducting audits on suppliers may include asking the following questions:
[] Security
[] Product support
[] End User training
[] Company Overview
[] Use of sub-contractors
[] Service delivery process
[] QMS application at the company
[] Development product life cycle
[] Key products development plans
[] Organization, roles, responsibilities, & training

13. Don’t be intimidated by your vendor comparisons

Utilize your URS to evaluate different vendors & note their advantages and disadvantages. If new information is found during the initial stage, feel free to revise your approved URS accordingly through the change control process. It is acceptable to make modifications or adjustments to the requirements to fit your needs until the final approval of the URS and it shall be revised the approved User Requirement Specification accordingly maintaining proper documentation.

14. What ought to be included in the URS?

The contents of a URS naturally include the following (but are not limited):
[] Functional requirements
[] Operational requirements
[] Technical requirements
[] Interface requirements
[] Data requirements
[] Security requirements
[] Regulatory requirements
[] Maintenance requirements
[] Availability requirements
[] Migration of any electronic data
[] Environmental requirements
[] Constraints to be observed
[] Life cycle requirements

15. Categorize Your Requirements

Categorize Your Requirements as-
[] Mandatory (High)
[] Beneficial (Medium)
[] Good to have it (Low)

16. Subjective Knowledge and Processing Step

To ensure that requirements, your professional knowledge is essential but not mandatory; if require you can seek help from an SME [Subject Matter Expert]. To identify key requirements of the system Process knowledge is required which are related to the manufacturing/servicing process. Look for the following key points-
[] Experience
[] Knowledge
[] Documentation

17. The requirements may be incomplete or not fully specified

Sometimes the requirements are not fully understood at the beginning of the project; Requirements evolve over time. URS shall be developed as per requirements when information is available. Don’t share incomplete User Requirement Specifications to the manufacturer to avoid any unwanted requirements.

Frequently Asked Questions

Are URS always required for validation?

At the initial stage of system/service/equipment/instruments, then URS is a valuable tool for ensuring the asking requirements. When an existing system is being validated then URS consider as a functional requirement. These two documents can’t be considered as single documents.

What is the benefit of good User Requirement Specification?

Requirements gathering is an important part of a good software/hardware/service/product development project. Good estimation, improved customer satisfaction, reduced cost, and project duration can all fail if good requirements are not selected and sufficient knowledge is not introduced in the selection If you are unclear about what you are delivering, no one can expect anything better from you.

There are Five main questions that shall be asked to develop any project:
[] Why we are doing it?
[] What do we need to do it?
[] What is the benefit?
[] How do we do it?
[] What is the timeframe?

If we fail to estimate project requirements or are unable to assume what is the requirement, can lead to a poor outcome of the project, and also lead to extra manpower, longer duration, and project costing.

Forced Degradation Study or Stress Testing Procedure

What is Degradation?

Forced Degradation Study before proceeding on it ,first of all  ”Degradation’‘ to be discuss first, This is the act of lowering to some degree or someone to a less respected state or position. A CEO of a multinational company resigning from his office is a degradation. It’s also a downcast state.

The word degradation is very much related to the degrade, which comes from Latin word Degradare. The word “Degradare” comes from “de”-, meaning “down,” & gradus, meaning “Step.” So, it is very much clear that the degradation as a step down, or feeling as though you’re a step below.

Degradation products

It is the unwanted chemicals which can generate during manufacturing, transportation & storage of pharmaceutical drug products & can affect efficacy of pharmaceutical drug products. A small amounts of pharmaceutical degradation products can affect crucial safety because of the potential to cause adverse effects in end user.

Subsequently, it is crucial to focus on formulation, storage conditions, transportation, distribution channel and packaging to prevent the formation of degradation products which can negatively affect quality, safety and efficacy of the pharmaceutical drug products.

To find out the main cause of degradation of the pharmaceutical product is the crucial point, various software and data tracking system can help in this matter. This system can provide useful information during transportation and storage of pharmaceutical products, the route shall be determined to estimate the main cause.

Presence of a genotoxic degradation product shall tend to more assessment if it identified on due time. The chemical structure of the substance shall be determined to identify the toxic alerting structures associated toxic products, products [Compound] without active structure is marked as ordinary impurities.

A risk/benefit analysis shall be done to evaluate the levels of degradation products and most of the nest pharmaceutical call its mandatory. During the development of any type of product either critical or non-critical drug, critical variable of the drug products shall be follow-up which will control the degree of degradation of impurities.

Now a days the impurity profile has been considered as the key point of the product quality. It is the essential part of the quality parameter for the various competent regulatory authority. The toxicological evaluation and impurity profile become the key point of the degradation products to confirm its certain level of efficacy. Various types of test method have been identified to investigate the degradation products, all of them assay method consider the best to all and it’s highlighted to prove its effectivity.

The purity, safety and efficacy of the product depend on the stability of the product and it is the critical parameter of all the parameter. A product must be stable at a certain period of time to prove its efficacy, potency and safety.

A less stable or changes of stability can create serious toxicological effect by forming toxic degradation products and deliver less active or less effective or less potent drugs to the end user. Under these circumstances, this is very crucial to known the actual behavior of the drug products in various surrounding or environmental conditions.

Dissolution test are considering the most quality control tool for the commercial batch to batch product to monitor its consistency over a certain period of time. It also provides significant information during post approval changes of the certain product as changes made in formulation, manufacturing process and different scale up procedure.

To confirm the quality, safety and efficacy, the chemical stability is very important for a pharmaceutical product. This is very important to know the environmental influences of a certain developed product in specific condition such as Heat [Temperature], Humidity [Relative Humidity] & Light [Photostability] and this also regulatory [ICH & FDA] requirements.

Data acquire from stability study denote the shelf life and storage condition of the specific tested drugs, the container closure system [Protective packaging system] also require to satisfy the regulatory expectation.

Different types of method/instruments are available to determine the degradant compounds which are readily present during the forced degradation study period. HPLC-UV [HPLC with UV detector] and HPLC-PDA [ HPLC with Photodiode Array Detector] is the renowned method and extensively used in pharmaceutical company at the time of degradation study and validation and development of various type of method.

LC-MS [HPLC with Mass Detector], GC-MS [Gas Chromatography with Mass Detector] and NMR [Nuclear Magnetic Resonance] spectroscopy are significant methods to detect the degradants’ structure.

What is Forced Degradation Study?

Exposure of specific sample at the unfavorable/stress condition of Heat [Temperature], Humidity [Relative Humidity], Light [Photostability], Oxidation and Acidic/Basic condition; observe/detect the changes of those sample or measure the rate of changes/degradation, mainly in Efficacy, Safety and Potency parameter of drug substance. Forced degradation study is the key point during the development of a specific drug. Determination of the type changes denote the modification or changes of the development process.

Now a days Force Degradation Study become the prerequisite to submit the NDA to regulatory authority and it became the quality parameter for the new product. During the regulatory submission, the Force Degradation Study data shall be submitted to get satisfactory result from FDA. Some of the best application of Force Degradation Study is depicted here-

[][]Developing and validating stability study indicating method as per regulatory guidelines [ICH Guidelines].
[][]To set up specification of degradants or impurities and to identify structure and toxicity.
[][]To set propose shelf life the specific product without performing Realtime stability data.
[][]To avoid incompatibility of drug products and excipients.
[][]Determination of the process related degradation products or impurities.
[][]Provide supporting data to lab investigations/OOS [out-of-specification] analysis.
[][]To provide regulatory compliance documents during submitting of ANDA/NDA to FDA.

It is a useful tool to predict the stability of any Active Pharmaceutical Ingredient (API) or formulation product. It helps to know about the impurities developed during the storage of drug products in various environmental conditions.

Forced degradation is performed by applying artificial methods and a drug is degraded forcefully. It is also known as stress testing. To assume the stability condition of API [Active Pharmaceutical Ingredient] and formulated product Forced degradation study plays an important role. It also helps to identify the impurities generated during storage of drug products in different environment stage.

Why Forced degradation study carried out?

Its play a vital role to develop and validating of stability study signifying method. At the time of developing phase of a new drug product, force degradation study performs to determine the degradation pathways of drug products & drug substances. It is very important to determine impurities of the degradant product, Forced degradation study quantify the number of impurities present on the specific drug substance. It helps to determine the molecular chemistry. Forced degradation study assure the more stable product. Help to develop the degradation profile. Stability related problem can be solved through Forced degradation study. Forced degradation study also highlight the following point of view-

[][]Evaluation of drug products & drug substance in solution.
[][]Determination of structural transformation of drug product & drug substance.
[][]Determination of the concentration of the degradation products.
[][]To identify the non-relevant impurities in the existence of the desired product.
[][]Separation of the product related degradants derived from intact placebo & excipients.
[][]Describe the degradation pathways of the specific drug substance.
[][]To categorize the degradation products which generate spontaneously during storage & use of products.
[][]To generate product related variants & develop analytical methods Forced degradation studies are performed during accelerated and long-term studies.

During the Forced degradation study, the degradation products may or may not be generate but it will show the degradation pathway of the product. This process will help them develop the analytical method of the relevant product and stability indicating analytical procedure. If any degradation occurs during performing of Forced degradation study, the degradation product shall be evaluated if it significant or minute, to robust the developed formulation.

How Forced degradation Study Conducted?

This study of the drug products or substances is generally conducted on the solid and solution stages at the high temperature exceeding accelerated stability condition which is above 40°C. Various condition are consider here as oxidation, hydrolysis, photolysis, polymerization and thermolysis. In Solution hydrolysis condition are investigated in broader pH range and in solid stage high relative humidity taken under consideration.

Control exposure of molecular oxygen or addition of oxidizing agents such as peroxides is use during investigating Oxidation in solution.
Applying heat in solid state effects of thermolysis are usually assessed. Light with wavelengths in the 300-800 nm range are use in Photolysis investigation in solution or the solid state. In an oxygen atmosphere photooxidation can be investigated with light under oxygen atmosphere. Measuring the rate of degradation, Drug substance polymerization can be investigated at the various drug substance concentrations in solution.

Extend of degradation

For validation of a chromatographic purity assay, degradation level of 10-15% is adequate to perform the activities. Forced degradation studies are not considered part of the formal stability program though forced degradation studies are a regulatory requirement & scientific necessity during development of a specific product. For conducting studies at the various phases of development the guidance gives various recommendations.

Selection of Forced Degradation Condition

In common industry practice, forced degradation is generally performed in different stress conditions, i.e., thermal, acid, alkali, peroxide, and UV, along with a control sample which also comply with ICH guidelines. There no specific range or rate of degradation in current industry practice but 5 to 30 percent degradation shall be taken into consideration and this can be achievable on any one of the above stress conditions.

Through stress testing, the aim of the degradation to be achieved to implement the control room temperature for the stability conditions. The conditions or concentrations of reagent shall be optimized if higher or lower degradations are observed.

During the degradation study Mass balance shall be demonstrated & it shall be around 100%, taking into attention margins of analytical errors. During mass balance evaluations, all the degradants /impurities must be calculated.

Any batch which is not be the part of regulatory submission can be used for the forced degradation study. For multiple strengths of the same placebos and different amounts, the highest ratio of placebo vs. API [Active pharmaceutical ingredient] shall be use.

Forced degradation of all the strengths shall demonstrate if placebos are different. Placebo & API [Active Pharmaceutical Ingredient] must be demonstrated to identify actual degradation pathways during the drug product force degradation study. All the placebos shall be considered for force degradation study if placebos are different for different strengths of drug product.

Various degradation conditions are depicted on the following table which is accepted by the regulatory authority [FDA] at the time of DMF/ANDA/NDA submission-

Degradation TypeReagent ConcentrationConditions to be appliedTimeRemarks
Acid5N HCL80deg.C1 HourConcentration, condition and time can change to optimize degradation
Alkali5N NaOH80deg.C1 HourDo
Peroxide10% H2O280deg.C1 HourDo
Heat/Thermal80deg.C80deg.C1 HourDo
UVExpose under UV light at 254nm wavelengthAmbient Temperature24 HoursTime can change to optimize degradation
ControlN/AN/AN/AN/A

Force Degradation shall be performed in solid or solution form though it is recommended that Force Degradation shall be executed in solution form using the mobile phase/diluent to get a homogeneous effect with better result. Force Degradation studies shall be started with harsh conditions (i.e., high temperature with high concentration of reagent) to shorten time of study.

Milder conditions shall be applied by reducing concentration of reagent with lowering temperature, etc. when degradation found 30% or above. Based on the initial degradation outcome, Degradation conditions can be optimized to achieve a target range.

To extend shelf life of chromatographic column, pH shall be adjusted about 7.0 for acid & alkali degradation. Different reagents & conditions shall be applied, e.g., Zn, H2SO4, etc. If degradation did not find in any of above conditions. A few numbers of molecule designated rock stable molecules as these molecules didn’t degrade any of the above stress condition. During a stability study This kind of molecule will not engender any additional impurities/degradant peaks.

If drug substance or product shows stability for two years at 30 ±2⁰C & 65 ±5% RH & Six months at 40 ±2⁰C & 75 ±5%RH, then the drug substance or product declared stable.
Concentration of the drug that is being tested for the degradation is a great point. For the degradation study 1 mg/ml of drug concentration is recommended though some degradation studies are done at concentration of drug in the final product. Main cause for this type of study is that precise amount of the degradation can be found in final product & their impact can be scrutinized.

Factors Affecting Forced Degradation Studies

Hydrolytic Degradation:

The reaction of chemical with water at different pH values occur in Hydrolysis degradation. In this degradation drug react with water in acidic & basic conditions. According to the stability of the drug substance concentration of the acid or base is selected where pH is 0.1 to 1.0 M HCl [Hydrochloric Acid] or H2SO4[Sulfuric Acid].

HCl & H2SO4 is used to maintain acidic conditions and 0.1 to 1.0M NaOH [Sodium hydroxide] or KOH [Potassium Hydroxide] used to generate basic conditions. Some materials are not readily dissolve/soluble in water freely; in that case other solvent are use to dissolve the water insoluble materials. Solvent shall be selected carefully so that it can’t degrade the selected drug substance.

Descriptive termPart of the solvent require per part of solute
Very solubleLess than 1
Free SolubleFrom 1 to 10
SolubleFrom 10 to 30
Sparingly solubleFrom 30 to 100
Slightly solubleFrom 100 to 1000
Very Slightly solubleFrom 1000 to 10,000
Practically insoluble10,000 and over

Reference: British Pharmacopoeia [BP]

Generally Chemical degradation shall be conduct in room temperature but if no sign of Chemical degradation occur at room temperature then room temperature shall be increase up to 50-60 ⁰C. A seven days timeframe shall be selected to perform the study. To prevent further degradation, Chemical degradation should be terminated using acid, base or buffer solution. Chemical analysis shall be done as soon as possible after completion of the test.

Oxidation Degradation:

in the forced degradation study, H2O2 (Hydrogen peroxide) is a widely used oxidizing agent. Hydrogen peroxide at 0.1% to3.0% solution is used at room temperature for 7 days is the suitable range to perform the activities. When more then20% degradation occur for a certain product, it can be considered abnormal cases.

Photolytic Degradation:

To determine the effect of light on the product during storage in the market Photostability testing of any drug take into consideration. light conditions shall be described during photostability. light source shall be cool white fluorescent lamp & wavelength of light shall be 200-800 nm (UV+ visible) which is also comply ICH guideline. The and the light intensity shall be not less than 200 watt-hours per sq meter and exposure time shall be not less than 1.2 million lux hours. To monitor the condition, a calibrated lux meter shall be use in place.

Result of forced degradation studies

[][]Forced degradation studies help to determine_
[][]Likely/Probable degradants
[][]Degradation paths
[][]Inherent stability of the drug molecule
[][]Validated stability indicating analytical method

When forced degradation studies to be performed?

This is the best practice to perform forced degradation studies at the time of development of new drug substance and new drug product. FDA prefer to perform it at phase III of the regulatory submission which is the best time to do the same. To establish the regular stability study, forced degradation studies can be prerequisite. This study can be done in different pH solution in the presence of light & Oxygen with high temperature & Humidity Level.

Generally, degradation study performs on single batch. There are two types of timeframes are use to perform stability study which Long Term [12 Months] & Short Term [6 Months]. 6 Months are performed at accelerated condition. Moreover, Intermediate Stability Study performed in a condition lesser than accelerated condition.

Force degradation studies are performed at pre-clinical phase or phase I of clinical trial so that sufficient time provides to identifying structure elucidation, degradation products. If forced degradation studies are performed properly, manufacturing process of the new product can be developed properly and stability-indicating analytical procedures can be select more effectively.

What is the regulatory obligation regarding Force Degradation Studies?

Following ICH [International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use] Guidelines has been depicted regarding forced degradation studies but it covers only marketing applications for new products but not for during clinical development.

[][]ICH Q1A: Stability Testing of New Drug Substances and Products.
[][]ICH Q1B: Photo stability Testing of New Drug Substances and Products.
[][]ICH Q2B: Validation of Analytical Procedures: Methodology.

What actually says this guideline?
