A reference to a standard is useful only when you can connect it to the product and the requirement being assessed. Before accepting a supplier’s statement of conformity, ask for that connection to be explained. A document with an impressive title may cover a different model, test or edition.
Define the product before checking the paperwork
Record the model, intended use and relevant configuration. List the components or options that could affect the assessment. For a product family, ask which variants the evidence covers and what supports that conclusion. Do not silently treat a report on one sample as a report on every version sold.
Check the reference precisely
Use the European Commission’s sector lists and their linked official publications. Match the full reference, including edition and amendments, and examine any stated limitations or dates. A later edition offered for sale is not automatically the edition with the relevant legal effect.
The presumption of conformity associated with a cited harmonised standard concerns the requirements it covers. It should not be described as an unlimited approval of every feature of the product. Other applicable requirements still need attention.
Build an evidence map
A practical working table can have five columns: requirement, selected approach, supporting evidence, product version and reviewer. For each row, link the actual report or technical record. Use “not yet assessed” where evidence is missing rather than leaving a blank that could be mistaken for approval.
- Does the report identify the same model as the sales documentation?
- Are the test method and edition clear?
- Do exclusions or conditions affect your intended use?
- Has a design change occurred since the evidence was produced?
- Who will review unresolved points before release?
This table is an organisational aid, not a prescribed universal form or a replacement for the documentation required by applicable legislation.
Plan the review when something changes
Ask the responsible technical specialist to assess changes in design, suppliers, intended use or references. Record the decision and the evidence behind it. A familiar certificate should not be reused automatically after a change merely because the product name remains the same.
For testing support, read how to evaluate an accredited laboratory. For terminology, see our introduction to harmonised standards.
Editorial correction: general promises of automatic market access and complete safety have been removed. A product-specific conformity decision needs the applicable legislation and competent assessment.
