This document specifies test methods and acceptance criteria, within the frequency range of 0,5 MHz to 15 MHz, for assessing the performance of equipment dedicated for determining thickness using pulse-echo ultrasound, e.g. according to ISO 16809.
This document only specifies the verifications required for the determination of thickness.
This document is applicable to instruments with numerical display and instruments with A-scan presentation, each using either single- or dual-transducer probes.
The tests described in this document can be used for verifying equipment covered by ISO 22232-1 and ISO 22232-2 when used for thickness determination.
