标准摘要
[中文适用范围]： 本文件规定了一种渗透检测方法，用于检测不连续性，例如裂纹、搭接、折叠、孔隙和未熔合，这些不连续性是使用白光或 UV-A (365 nm) 辐射对待测材料表面开放的。 。 它主要适用于金属材料，但也可以对其他材料进行，只要它们对测试介质呈惰性并且不是过多的多孔（铸件、锻件、焊缝、陶瓷等）。 本文件还包括工艺和要求控制测试，但不打算用于验收标准。 它既不提供与特定应用的各个测试系统的适用性相关的信息，也不提供测试设备的要求。 注 1：ISO 3452-2 和 ISO 3452-3 中规定了确定和监测所用渗透检测产品基本性能的方法。 注2：本文件中使用的术语“不连续性”是指不包括有关可接受性或不可接受性的评估。 注 3：CEN/TR 16638 涉及使用光化蓝光的渗透测试。 [外文原描述]： This document specifies a method of penetrant testing used to detect discontinuities, e.g. cracks, laps, folds, porosity and lack of fusion, which are open to the surface of the material to be tested using white light or UV-A (365 nm) radiation. It is mainly applied to metallic materials, but can also be performed on other materials, provided that they are inert to the test media and not excessively porous (castings, forgings, welds, ceramics, etc.) This document also includes requirements for process and control testing, but is not intended to be used for acceptance criteria. It gives neither information relating to the suitability of individual test systems for specific applications nor requirements for test equipment. NOTE 1 Methods for determining and monitoring the essential properties of penetrant testing products to be used are specified in ISO 3452-2 and ISO 3452-3. NOTE 2 The term "discontinuity" is used in this document in the sense that no evaluation concerning acceptability or non-acceptability is included. NOTE 3 CEN/TR 16638 addresses penetrant testing using actinic blue light.
