scope:

This European Standard specifies the general principles required for Leak Detection by the acoustic emission (AE) testing. The Standard is addressed to the application of the methodology on structures and components, where a leak flow as result of pressure differences appears and generates 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 will be discussed. It also includes the guidelines for the preparation of application documents, which describe specific requirements for the application of the AE method. Different application examples will be given. Unless otherwise specified in the referencing documents, the minimum requirements of this standard are applicable.
