This document specifies methods, tolerances and acceptance criteria for verifying the performance 
of combined ultrasonic test equipment (i.e. instrument, probes and cables connected) by the use of 
appropriate standard calibration blocks.
These methods are specifically intended for manual test equipment, i.e. ultrasonic instruments 
according to ISO 22232-1, and for manual ultrasonic non-destructive testing with single- or dual-
transducer probes according to ISO 22232-2. This document is also applicable for multi-channel 
instruments. For automated test equipment, different tests can be needed to ensure satisfactory 
performance.
The specified methods are intended for the use by operators working under site or shop floor conditions.
These methods are not intended to prove the suitability of the equipment for particular applications.
This document excludes ultrasonic instruments for continuous waves.
This document also excludes ultrasonic phased array systems, see e. g. ISO 18563-3. If a phased array 
instrument is used in combination with single- or dual-transducer probes, this document is applicable 
to this combination.st edition 2020-10 Non-destructive testing — Characterization and verification of ultrasonic test equipment — Part 3: Combined equipment Essais non destructifs — Caractérisation et vérification de l'appareillage de contr？le par ultrasons — Partie 3: Equipement complet Reference number ISO 22232-3:2020(E) ？ ISO 2020 ISO 22232-3:2020(E) COPYRIGHT PROTECTED DOCUMENT ？ ISO 標準截圖
