Restricted Substance Limit Register

How to read this sheet

Every limit on this register is yours. Nothing here carries a regulatory figure of its own and nothing is updated when a list is revised, because a stale limit reading as compliance is worse than no tool: it is acted on. Enter the list you were issued, at the revision you were issued it, and re-enter it when your customer reissues it. Fraction reaching the article converts a chemical-basis result to an article-basis one - a formulation at 2% add-on is 0.02 - and is left at 1 when the article itself was tested; it is a mass-fraction carry-over and assumes nothing is lost in curing, washing or drying, which for a substance that volatilises or rinses is conservative. Expanded uncertainty is taken as entered rather than derived, at whatever coverage your report quotes; the free measurement uncertainty budget calculator on this site builds that figure from its instrument, sampling, conditioning, operator and method terms. A substance passing as read and failing once its uncertainty is placed against the limit is reported separately, because that is the population a retest resolves and a rejection does not. Family limits are summed on the article basis and compared against the tightest limit any member carries; a family over its limit where every member passed individually is counted on its own line, since that is the failure a register read row by row never shows. A row with no limit entered is not counted as a pass - it is a row nobody can judge, and it is excluded from the tested count rather than quietly cleared. None of this is a compliance certificate, a legal opinion, or a substitute for the accredited report it takes its numbers from.
