Layout inspection, functional testing & appearance items (IATF only)
Plain-language summary
Periodically re-prove the whole part: layout inspection (every dimension) and functional verification per control plan and customer frequency — and for appearance parts, masters, evaluation conditions and qualified people.
What the clause is really asking
Layout inspection and functional testing per customer engineering and control plan requirements at the customer-defined frequency, results available for review. Appearance items require: appropriate evaluation resources (lighting, masters for colour/grain/gloss), maintained masters and equipment, and verified competent evaluators.
What auditors look for
Auditors ask for the latest layout inspection per part family against the required frequency, full-dimension results, and in appearance areas: master condition and control, lighting spec, evaluator qualification records.
Typical evidence
Layout inspection schedule and reports; functional test results; appearance masters register with condition checks; lighting verification; evaluator qualifications.
How to comply — recommendations
Diarise layout inspections per part family annually (or customer frequency) and treat masters like gauges: registered, condition-checked, replaced on schedule. Qualify appearance evaluators formally — eyesight tests included.
Common nonconformities
Layout inspections years overdue; masters faded/damaged but still in use; appearance evaluation under random lighting by whoever is free.
