Non-destructive testing - Ultrasonic testing - General principles (ISO 16810:2024)
SIST EN ISO 16810:2025

This document specifies the general principles for the ultrasonic testing of industrial products that permit the transmission of ultrasound.
The specific conditions of application and use of ultrasonic testing, which depend on the type of product to be tested, are described in documents which can include:
—     product standards;
—     specifications;
—     codes;
—     contractual documents;
—     written procedures.
This document specifies the minimum applicable requirements, unless otherwise specified in the referencing documents.
This document does not specify:
—     extent of testing and scan plans;
—     acceptance criteria.
This document describes only conventional probes, however, the general principles for ultrasonic testing also apply to ultrasonic testing using array techniques. If array techniques are used, then additional steps or verifications can be needed.

Non-destructive testing - Characterization and verification of ultrasonic phased array equipment - Part 2: Array probes (ISO 18563-2:2024)
SIST EN ISO 18563-2:2024

This document specifies characterization tests to be performed at the end of the fabrication of an array probe. It defines both methodology and acceptance criteria.
This document is applicable to the following array probes used for ultrasonic non-destructive testing [phased array technique or signal processing technique, e.g. full-matrix capture (FMC) and total-focusing technique (TFM)] in contact technique (with or without a wedge or delay line) or in immersion technique, with centre frequencies in the range 0,5 MHz to 10 MHz:
a)       array probes with elements in one direction:
—    1-D-linear array (linear array);
—    1-D-curved array;
—    annular array;
b)       array probes with elements in two directions:
—    2-D-array (matrix array);
—    sectorial annular array;
—    partial sectorial annular array.
This document does not give methods and acceptance criteria to characterize the performance of an ultrasonic phased array instrument or the performance of a complete system, which are given in ISO 18563–1 and in ISO 18563–3.

Non-destructive testing - Acoustic emission testing (AT) - Leak detection by means of acoustic emission (ISO 18081:2024)
SIST EN ISO 18081:2024

This document specifies the general principles required for leak detection by acoustic emission testing (AT). It is addressed to the application of the methodology on structures and components, where a leak flow as a result of pressure differences appears and generates acoustic emission (AE).
It describes phenomena of the AE generation and influence of the nature of fluids, shape of the gap, wave propagation and environment.
The different application techniques, instrumentation and presentation of AE results are discussed. Also included are guidelines for the preparation of application documents which describe specific requirements for the application of the acoustic emission testing.
Annex A gives procedures for some leak-testing applications.

Non-destructive testing - Characterization and verification of ultrasonic phased array equipment - Part 3: Complete systems (ISO 18563-3:2024)
SIST EN ISO 18563-3:2024

This document addresses ultrasonic test systems implementing array probes, for contact technique (with or without wedge) or for immersion technique, with centre frequencies in the range of 0,5 MHz to 10 MHz.
This document provides methods and acceptance criteria for determining the compliance of the complete system (see 3.2). Its purpose is for the verification of the correct operation of the system prior to testing or verification of the absence of degradation of the system.
The methods are not intended to prove the suitability of the system for particular applications but are intended to prove the capability of the complete system (used for an application) to operate correctly according to the settings used. Tests can be performed on individual ultrasonic beams (for phased array technique, see 9.4.4) or on resulting images (for phased array technique and total focusing technique, see 9.4.3).
The tests can be limited to the functions that are intended to be used for a certain application.
This document does not cover the sensitivity setting of the system for a specific application. Nor does it apply to the characterization or verification of the mechanical scanning equipment. It is intended that these items will be covered by the test procedure.
This document does not address the phased array technique using tandem technique.
The characterization of beams, as recommended in case of dead elements or for more in-depth knowledge of the beams, is presented in Annex A. It is not applicable for signal processing technology using arrays.
NOTE            Unless stated otherwise, in this document ‘TFM’ and ‘TFM technique’ refer to the total focusing technique as defined in ISO 23243, and to related techniques, see for example ISO 23865 and ISO 23234.
