ISO 3452-1:2013规定了用于检测不连续性的渗透检测方法，例如裂纹，褶皱，褶皱，孔隙率和缺乏融合，其对被测材料的表面开放。它主要应用于金属材料，但也可以在其他材料上进行，只要它们对测试介质是惰性的，而不是过多的孔（铸件，锻件，焊缝，陶瓷等） 它还包括过程和控制测试的要求，但不旨在用于验收标准，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

ISO 3452-1:2013 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. 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.) It also includes requirements for process and control testing, but is not intended to be used for acceptance criteria and gives neither information relating to the suitability of individual test systems for specific applications nor requirements for test equipment.
