Emergency lighting testing requirements (2 sources)

Every row is a verbatim sentence read from the named source's own page through our fetch service on the date shown, hash-pinned to the stored read (the sha of the page's visible text; the raw page is mirrored to R2).

3 of the 18 named sources that could be read published a usable figure; 15 published none and are recorded as not published, never filled in; 1 could not be read (blocked, dead or unreachable) and count nowhere.

The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source in day (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 24 candidate sentence(s) were refused by a reviewer with the reason recorded.

The fuller derivation this dataset is chartered to grow into (not yet what the figures above are; they are each source's own published figure as read): one row per jurisdiction per duty - test interval, test duration, who may perform it, what the record must contain, how long it must be kept, the penalty clock on a failure - each quoted verbatim from the authority with its effective date and code edition; the derived figure nobody publishes is the map of which code edition each state and each federal regime is actually on, so a reader can see that the '90 minutes' of NFPA 101 7.9.3 is 3 hours under BS 5266 in Britain and 1.5 hours as CMS words it, and changed-since on every adoption.

24 candidate sentences on these pages were refused by a reviewer; each refusal and its reason is recorded in the review ledger.
