How it works

Check a standard in three steps

Official pages only show today's dates. We archive them every day and keep every change: dated, sourced, citable.

Who it is for. Manufacturers, compliance and quality engineers, notified bodies and consultants who need to know whether the standards in a technical file still give presumption of conformity under the Machinery, Radio Equipment, General Product Safety, Cyber Resilience Act and AI Act rules.

Status

Where every regime stands

One row per regulation. The dates shown are today's official positions; the archive holds every previous one. Each strip marks the Official Journal citation batches for that regime on one shared axis, 2004 to today.

Changelog

What moved on the official record

Every entry links the source that changed. The full history is preserved as dated diffs.

Drift

Where the clock stands

Each bar is the distance between today and a dated obligation, from the regulation text or the standardisation request. Red means the date passed with the standards still uncited. How drift is measured →

20 January 2027, in 73 days: 906 Machinery standards stop giving presumption of conformity, the end of legal effect the Commission's list sets on them.

Citation cadence

How often each list actually moves

Every row in the Commission's lists carries the Official Journal date it was published on. Counting the distinct dates gives the number of citation batches per regime and the gaps between them. Days since the latest batch in red once it is past the median gap. Rebuilt daily; also at /data/cadence.json.

Method

How the archive works

What the numbers count. Standards under watch counts distinct standard references across the Commission's summary lists, which is why machinery dominates the total: it is by far the largest list. The lists themselves hold more rows than references (1,833 in this capture), because one standard can appear on several rows, one per amended version. Every reference has its own page under the standards index, and every row is shown there. Sources captured daily counts the official pages and documents fetched each run, not the standards in them. Counts taken from a single decision text on EUR-Lex are a different measurement and are labelled as such wherever they appear.

Full methodology, including how drift is measured →

What happens when a source fails. A fetch that errors is recorded as an error and retried, not treated as a change. Where a run has produced entries that look like movement but are not, we annotate that run on the changelog and say so. Three of the entries below are annotated that way, because they were our own filter and fetch behaviour rather than the official record moving.

Analysis

The second CRA standards deadline has passed →

On 30 October 2026 items 16 to 41 of the standardisation request fell due, with no harmonised standard cited in the Official Journal. The dated record, from primary sources.
