Read the named organisation, covered activities, locations and validity information, then verify it through the appropriate issuer or recognised channel.

Confirm the quoted configuration against the agreed drawing.<\/p>\n<h2>Match the document to the requirement<\/h2>\n<p>Identify what evidence your project actually requires and who is responsible for determining that requirement. A management-system certificate, a material report and a product test report answer different questions. Ask for the complete document and distinguish those categories before accepting a supplier\u2019s general statement of certification.<\/p>\n<h2>Check identity and scope<\/h2>\n<p>Compare the organisation and location on the document with the entity and operation involved in the order. Read the covered activities and any stated limits. Where authenticity or current status matters, verify with the issuer or its published verification route rather than relying only on a forwarded image.<\/p>\n<h2>Connect evidence to the ordered product<\/h2>\n<p>If the requirement concerns a material or product result, check that the report identifies the applicable sample, construction or batch and the stated test conditions.
