How to record the date and edition behind a supplier claim

A link can keep working while the document or standard it points to changes. A directory that records only the URL cannot explain which version supported a sentence when it was written.

What the primary source can establish

The ISO 9001 official standard page is the first-party reference for this guide. At the 2026-09-27 review, ISO lists the 2026 edition and describes quality management system requirements. It does not investigate or endorse any named supplier on Source Ledger. The steps below are our editorial method for making a buyer-facing field more precise.

A field-level check

Record the retrieval date, edition or document version, and the exact field observed. For standards, keep the edition shown on the official page and check whether a supplier document cites the same edition. Set a review trigger when the underlying record changes.

Write down the exact field, the party that supplied the information, the original document or page, the date seen and the scope of the check. If a reviewer took an action, record that action rather than a general “verified” label. Reopen the source when the transaction or underlying document changes.

Where the inference stops

Do not infer that a certificate is current merely because an ISO standards page is current. Standards pages describe standards; certificates are issued and scoped separately. A date belongs to the evidence item, not to the supplier forever.

A missing answer is a question to resolve, not permission to substitute a guess. Separate a statement by the supplier from a public record and from a documented human review. No source in this article proves a quality ranking or an existing buyer relationship.

What to record before deciding

In the directory log, show last checked and next trigger rather than a timeless “current” label. Update the wording when an edition changes and preserve the earlier record as history.

This entry describes how to evaluate evidence. It is not a dossier for a real company, an approval decision or a substitute for transaction-specific professional review.

Common question

Does an official standard page prove a supplier follows that edition?

No. It identifies the standard and edition. Supplier compliance requires evidence tied to the supplier, certificate scope and relevant activity.
