Non-destructive testing - Ultrasonic testing - Characterization and verification of ultrasonic equipment for the determination of thickness (ISO/DIS 16831:2024)

ISO 16831:2012 specifies methods and acceptance criteria for assessing the performance of instruments for measuring thickness using pulse-echo ultrasound.
ISO 16831:2012 covers both direct (digital) reading and waveform display types using single or dual element probes.
ISO 16831:2012 can be used for verifying equipment covered by EN 12668 when used for thickness measurement.
