Each page cites the clause it comes from. This page lists the sources behind the record, the date each was read and the role each plays. A source that is not listed here is not used.

What is not a source
Secondary summaries, search snippets and memory are not sources. A clause answer that cannot be traced to the published text is not shipped. The site does not quote the amendment because the amendment is not public, and it does not present a secondary reading as the standard.
How the record is verified
Each clause line was written from the published base standard, the public preview and the NPSA rating guidance, and checked against the clause. The strict seven-word overlap test is run against the sources before release. The ISO record is re-read on every refresh and the build fails on a change. The method in full.
THE RECORD THIS IS BUILT FROM
Read from the public record, not invented
Every clause answer on this site points to the official record or the public preview behind it, so you can check any line yourself. The register holds 25 records, 111 evidence lines and 100 common failure lines. The dates come from the ISO stage record. The amendment text is not public, and this site does not describe what it changes.
