DIN Standards Committee Materials Testing

Overview

This International Standard specifies the general principles required for leak detection by acoustic emission testing (AT). This International Standard 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 methods, instrumentation and presentation of AE results are discussed. The International Standard also includes guidelines for the preparation of application documents which describe specific requirements for the application of the AE method. This International Standard contains different application examples. Unless otherwise specified in the referencing documents, the minimum requirements of this International Standard are applicable. This document (EN ISO 18081:2016) has been prepared by Technical Committee ISO/TC 138 "Non-destructive testing", the secretariat of which is held by AFNOR, in collaboration with Technical Committee ISO/TC 135 "Non-destructive testing". The responsible national committee is Working Committee NA 062-08-23 AA "Ultraschallprüfung" ("Ultrasonic testing") at DIN Standards Committee Materials Testing (NMP).
