Measurement and traceability39 / 39

Choose a swab method for the result you need. Record site, timing, kit, and result, using the site's procedure for acceptance criteria.

For quick-frozen food, ambient temperature is recorded with a device meeting TS EN 12830, 13485 and 13486, at frequent and regular intervals, with date and time, and kept for at least one year.

ATP and HACCP wording is not a purchasing file. Check model, scope, issuer, date and your own use separately on the document itself.

Container count alone is not capacity. Track use, return, excursions, loss, washing and maintenance with explicit numerators and denominators.

A fixed trip count cannot validate every route. Assess real loads, temperature records, workflow and changing conditions against criteria set in advance.

Hold time depends on starting conditions, plate layout, fill and openings. Measure your acceptance curve on the longest route.

Verify model and serial, inspect the closure surfaces, then test with a representative load on route. Record defects before judging cosmetic marks.
