标准范围

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、褶皱、气孔和未熔合，这些不连续性对使用白光或UV-a（365？nm）辐射进行测试的材料表面是开放的。它主要适用于金属材料，但也可以在其他材料上进行，前提是这些材料对试验介质是惰性的，并且没有过多的多孔性（铸件、锻件、焊缝、陶瓷等）本文件还包括工艺和控制测试的要求，但不用于验收标准。它既没有给出与特定应用的单个测试系统的适用性相关的信息，也没有给出测试设备的要求。注？1？ISO 3452-2和ISO 3452-3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“不连续性”一词的含义是，不包括关于可接受性或不可接受性的评估。注3:CEN/TR 16638涉及使用光化蓝光进行渗透检测。

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.
