Monitoring & measuring resources
Plain-language summary
Making sure the instruments and methods you use to check product are themselves trustworthy — the right tool, working properly, calibrated where it matters.
What the clause is really asking
If you cannot trust your measurements, you cannot trust your product decisions. The clause wants you to identify which measurements affect product conformity, choose suitable equipment for them, and keep that equipment fit for purpose — including traceable calibration where measurement traceability is required, and acting on product risk when an instrument is found out of tolerance.
What auditors look for
Auditors pick instruments on the shop floor and trace backwards: Is this gauge on the register? Calibration status current and visible? Certificate traceable to a national/international reference? They check storage and handling, look for 'private' instruments not in the system, and probe the hard question: when something was found out of calibration, did you assess the product measured with it since the last good calibration?
Typical evidence
Equipment register; calibration schedule and certificates; calibration status labels; out-of-tolerance investigation records; MSA studies (automotive); records of verification before return to use.
How to comply — recommendations
Keep one register with a unique ID per instrument. Use external SANAS-accredited labs for reference standards and calibrate working gauges in-house against them if volumes justify. Sticker every instrument with status + due date. Write a one-page out-of-tolerance reaction procedure BEFORE you need it. Remove or clearly mark 'indication only' instruments.
Common nonconformities
Personal verniers/micrometers in toolboxes not on the register; expired calibration stickers; certificates with no traceability statement; no product-impact assessment after a failed calibration; thermometer/pressure gauges on equipment forgotten because 'maintenance owns them'.
