Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of ISO document should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

This document was prepared by Technical Committee ISO/TC 135,Non-destructive testing, Subcommittee SC 9, Acoustic emission testing, in collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/TC 138, Non-destructive testing, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

This second edition cancels and replaces the first edition (ISO 18081:2016), which has been technically revised.

The main changes are as follows:

— Figure 1 has been improved;
— term “AT equipment” has been replaced by “AE instrument” in the whole document;
— term “system” has been replaced by “instrument” in the whole document;
— Figure 2 showing an adjustable air jet has been added;
— Formula (1) has been corrected;
— Table 2 “Leakage grading and the influence of leak flow dynamic on AE activity“ has been added;
— editorial corrections throughout the document.

Any feedback or questions on this document should be directed to the user’s national standards body. A complete listing of these bodies can be found at www.iso.org/members.html.
