Institute of European Standards and Quality 
Material and intended purpose
A material is identified by its specification, composition or relevant characteristics and intended use. Grade, batch and processing history can matter to an evidence review. A trade name alone may not establish technical identity.
Specifications and claims
Questions may concern consistency between purchasing requirements and supplier information, evidence for a material characteristic or the basis of a composition or origin claim. The required degree of detail follows from the decision to be supported.
Data and methods
Analytical information should identify the sample, method, reporting basis and relevant limitations. A test result requires a clear relationship to the lot or material being considered. Different methods or reporting conventions may affect comparability.
Quality and traceability work
A scoped project may examine specifications, records and the chain linking a material to supporting evidence. It should distinguish physical identity, transaction records and technical measurements rather than assuming that one establishes the others.
Outputs and limits
A documentary or technical review does not automatically establish compliance with every chemical or product requirement. Specific testing, regulatory conclusions and formal verification require an appropriate basis and identified responsible body.
Technical resources
Laboratory quality and traceability guidance can help users ask proportionate questions about methods and records. The intended use of the result remains central.
Discuss the material question
Identify the material, specification, lot or batch where relevant, intended use and exact claim or quality question. Describe the evidence available and the purpose of the requested output.
