Description (English):

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.

Abstract

Overview

ISO 22232-3:2020 - Non‑destructive testing - Characterization and verification of ultrasonic test equipment - Part 3: Combined equipment specifies practical methods, tolerances and acceptance criteria for verifying the performance of combined ultrasonic systems (instrument + probe(s) + cable(s)) using standard calibration blocks. It is intended for manual ultrasonic NDT (single‑ or dual‑transducer probes) and is applicable to multi‑channel instruments used under site or shop‑floor conditions. The standard excludes continuous‑wave instruments and phased‑array systems (except when a phased‑array instrument is used with single/dual probes).

Key topics and requirements

Scope of verification
- Tests apply to the combined assembly (instrument, probe(s), cables) rather than individual components.
- Baseline measurements must be recorded for subsequent comparisons, including instrument settings and test block/cable details.
Daily and weekly test regime
- Daily: visual inspection (physical state, probe contact surface), probe index point and beam angle checks for angle‑beam probes.
- Weekly (or each use): vertical linearity, sensitivity and signal‑to‑noise ratio, and pulse duration. (Weekly tests may be performed each time equipment is used.)
Specific checks and acceptance criteria
- Probe index point: verified on ISO calibration blocks; measured position should be within ±1 mm of nominal.
- Beam angle: read from calibration block; measured angle should be within ±2° of nominal.
- Sensitivity, SNR, vertical linearity, pulse duration: baseline and routine checks using defined procedures to ensure consistent performance.
Personnel and reporting
- Operators performing verifications shall be qualified per ISO 9712 or equivalent.
- Results and baseline data must be documented and retained; non‑compliance requires repair/replacement or further verification per ISO 22232‑1/‑2.

Applications and users

Who uses ISO 22232-3:

NDT technicians and inspectors performing manual ultrasonic testing in shops, plants and field sites.
Quality assurance and calibration personnel establishing routine verification programs.
Manufacturers and service providers of ultrasonic instruments, probes and calibration blocks. Practical applications:
Routine pre‑use verification to detect probe wear, cable/connectivity issues or instrument drift.
Establishing documented baseline performance before critical inspections.
Ensuring traceability and repeatability of ultrasonic inspections in maintenance, fabrication and safety‑critical industries.
