NF EN ISO 18081, A09-026 (07/2024)

ISO 18081:2016 defines the general principles required for leak detection using acoustic emission testing. This International Standard addresses the application of the methodology on structures and components, where leakage flow due to pressure differences occurs and generates acoustic emission (AE). It describes the phenomena of AE generation and the impact of the nature of fluids, the shape of space, the propagation of waves and the environment. The different application methods, instrumentation and presentation of EA results are described. This standard also contains the guidelines for the preparation of application documents, which describe the specific requirements for the application of the method by EA. Different application examples are given. Unless otherwise specified in the referenced documents, the minimum requirements of this International Standard apply.
