Institute of European Standards and Quality 
Product and user
A consumer product should be identified through its design, materials, intended function and intended users. Use by children or other groups can change the questions that need examination. Packaging and instructions form part of the product information relevant to that assessment.
Quality and safety questions
Typical questions concern the relationship between performance claims and evidence, consistency of product specifications, foreseeable conditions of use and the adequacy of supplier information. Quality characteristics and safety requirements are considered in their proper context.
Requirements and evidence
Relevant evidence may include specifications, drawings, material information, instructions and test reports. The report must relate to the product and characteristics in question. Similar branding, a common supplier or a photograph does not establish that relationship.
Work that can be scoped
A defined assignment may address a technical file, a quality requirement or the evidence supporting a claim. The scope identifies the product family, variant and intended use, together with the particular questions and output agreed.
Meaning of the result
A review limited to named characteristics does not establish conformity with every applicable product requirement. Testing and any legally prescribed third-party procedure must be identified separately, with the responsible provider and relevant authority.
Guidance and professional learning
Resources on product evidence, specifications and supplier quality can support the day-to-day work of manufacturers and purchasers. They are used alongside the product's actual requirements.
Describe your product
Give the product category, intended users, model or variant, market context and the decision to be supported. Identify available evidence and any material changes since it was produced.
