ISO 18081:2016规定了通过声发射测试(AT)进行泄漏检测所需的一般原则。这是针对结构和组件的方法的应用,其中出现由于压力差引起的泄漏流并产生声发射(AE)。
它描述了AE产生的现象和流体性质,间隙形状,波浪传播和环境的影响。
讨论了AE结果的不同应用方法,仪器和演示。还包括准备应用文件的准则,其中描述了应用AE方法的具体要求。
给出了不同的应用实例。
除非参考文件另有规定,否则本国际标准的最低要求是适用的
ISO 18081:2016 specifies the general principles required for leak detection by acoustic emission testing (AT). It is addressed to the application of the methodology on structures and components, where a leak flow as a result of pressure differences appears and generates acoustic emission (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 is discussed. Also included are guidelines for the preparation of application documents which describe specific requirements for the application of the AE method.
Different application examples are given.
Unless otherwise specified in the referencing documents, the minimum requirements of this International Standard are applicable.
