It specifies requirements for the performance, calibration, and verification of equipment used to measure material thickness in industrial settings.

The standard ensures that thickness measurements are accurate, repeatable, and traceable to international metrology references. Without compliance with ISO 41269, inspection reports may not be accepted by regulatory bodies or clients.
Standards are living documents. ISO periodically reviews and revises each standard every five years. If you are using an older PDF of ISO 41269, you may be missing critical changes that affect compliance. If you believe the standard exists (e
