本标准适用于对压力容器或其它构件进行声发射(以下简称AE)检验的单位、有关的安全保险机构和AE检查组织。标准给出了探测突发,分立AE信号源的方法。突发、分立事件可能是应力下裂纹扩展造成的,因此可用来发现裂纹。考虑到实际AE检验需要有关单位的具体协议以及AE方法仍处于发展阶段,本标准只提出一些必要的方法,而没有给出更 This standard applies to the pressure vessel or other components for acoustic emission (hereinafter referred to as AE) inspection unit, the safety and security agencies and AE inspection organizations. The standard gives a way to detect burst, discrete AE sources. Bursts, discrete events can be caused by crack growth under stress and can therefore be used to detect cracks. Taking into account the actual AE test requires the specific agreement of the relevant units and the AE method is still in development stage, this standard only put forward some necessary methods, but did not give more
