Non destructive testing - Acoustic emission - Examination of metallic pressure equipment during proof testing - Zone location of AE sources; English version of DIN EN 15495:2008-02
The purpose of this standard is to describe the methods for conducting an acoustic emission (AE) examination of
metallic pressure equipment during acceptance pressure testing using a zone location procedure. General
principles of Acoustic Emissions are described in EN 13554.
The objectives of the AE testing are to provide 100 % volumetric testing to define and grade zones of the structure
which are acoustically active with burst type AE. The method should be regarded as supplementary to planar
location. Planar location provides the source identification and characterisation. Zone location may also be applied
in such cases where location of AE sources by planar location procedures according to EN 14584 is not possible.
The method identifies the need for further evaluation or follow-up by other NDT in localized zones.
