本标准的目的是描述在使用区域定位程序的接受压力测试期间对金属压力设备进行声发射（AE）检查的方法。声学辐射的一般原理在EN 13554中有所描述。 AE测试的目标是提供100％体积测试，以定义和分级具有爆发型AE的声学活动结构的区域。该方法应视为平面位置的补充。平面位置提供源识别和表征。在这种情况下，区域位置也可以应用于根据EN 14584的平面定位程序的AE源的位置是不可能的。 该方法确定了其他无损检测在局部区域进一步评估或后续的需要

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.
