Visible pen etra nts are typically red in color, and represe nt the lowest sen sitivity. Fluoresce nt pen etra nts contain two or more dyes that fluoresce whe n excited by ultraviolet

9、(UV-A) radiatio n (also known as black light).渗透按灵敏度是有划分的。可见渗透液通常是红色，代表最低灵敏度。当作用于紫外线 (UV-A辐射(也称为黑色光)时，荧光渗透液含有两个或两个以上的荧光染料。o 3 aerosol spray cans (red dye penetrant, cleaner, developer)气溶胶喷雾罐(红色染料渗透剂，清洁剂，开发人员)o Some lint free clothes, and和一些免费的皮棉衣服o Adequate visible light足够的可见光8.0 Test Method:检测方法Bel

11、, grease or any loose scale that could either keep penetrant out of a defect, or cause irrelevant or false indications. Cleaning methods may in clude solve nts, alkali ne clea ning steps, vapor degreas ing, or media blast ing. The end goal of this step is a clea n surface where any defects prese nt

12、are ope n to the surface, dry, and free of con tam in ati on.被检测的表面应该去除污垢、油漆、油、油脂和疏松的氧化皮以防止渗透时出现缺陷， 或者引出无关的或错误的结果。清洗方法包括溶剂、碱性清洗步骤，蒸汽脱脂或媒体爆破。 这一步的最终目标是获得一个干净的、没有任何缺陷暴露的、干燥的，没有污染的表面。8.2 Application of Penetrant:渗透剂的施加The pen etra nt is the n applied to the surface of the work piece being tested. The p

13、en etra nt is allowed "dwell time" to soak into any flaws (ge nerally 10 min utes).渗透剂被施加在被检测工件的表面。渗透允许停留时间一般为十分钟，以检测任何缺陷。8.3 Excess Pen etra nt Remova多 余渗透剂的去除The excess pen etra nt is the n removed from the surface. The removal method is con trolled by the type of pen etra nt used. Water

14、-washable, solve nt-removable are the com mon choices. When using solve nt remover and lin t-free cloth it is importa nt not to spray the solve nt on the test surface directly, because this can remove the penetrant from the flaws. If excess pen etra nt is not properly removed, once the developer is

15、applied, it may leave a backgro und in the developed area that can mask in dicati ons or defects. In additi on, this may also produce false indications severely hindering ability to do a proper inspection.然后将多余的渗透剂从表面去除。去除方法取决于渗透剂使用的类型。水清洗和溶剂去 除是常见的选择。当使用溶剂清洗剂和不起毛的布很重要的是不要直接把清洗剂喷到测 试表面，因为这样会把缺陷表面的渗透

16、液也去除。如果多余的渗透液被不适当的去除， 当施加显像剂的时候，可能会在显像区域留下一些可以掩盖迹象或缺陷的背景，此外,这也可能会产生错误的迹象，严重阻碍了做一个正确的检查。8.4 Application of Developer:显像剂的施加After excess penetrant has been removed a white developer is applied to the sample. Choice of developer is governed by penetrant compatibility (one can't use water-soluble or

17、 suspe nd-able developer with water-washable pen etra nt), and by in specti on con diti ons. The developer draws pen etra nt from defects out onto the surface to form a visible in dicati on, commonly known as bleed-out. Any areas that bleed-out can indicate the location, orie ntati on and possible t

18、ypes of defects on the surface.在多余的渗透剂被去除后，一个白色的显像剂被施加到样品。显像剂的选择取决于渗透 的兼容性(不能把水溶性的或者可暂停的显像剂用于水洗渗透)和检验条件，显像剂使 渗透液离开缺陷的表面从而形成一个可见的迹象，俗称渗出。任何渗出的区域可以表明 在表面的缺陷位置、方向和可能的缺陷类型。8.5 In spectio n:检验 The in spector will use visible light with adequate in ten sity for visible dye pen etra nt. Inspection of the t

19、est surface should take place after a 10 minute development time. This time delay allows the blott ing acti on to occur. The in spector may observe the sample for in dicati on formati on whe n using visible dye. It is also good practice to observe in dicati ons as they form because the characteristi

20、cs of the bleed out are a significant part of interpretation characterization of flaws.检验员要使用足够强度的可见光做可见染料渗透。表面的检测发生在显像时间10分钟后。这个时间延迟允许有印迹产生。检验员可以使用可见染料观察印迹在样品上的的形 成过程。观察它们形成的迹象也是一个好的做法因为这也是解释缺陷特征的重要部分。8.6 Post Clea ning 验后清洗The test surface is often cleaned after inspection and recording of defects

21、, especially if post-i nspect ion coati ng processes are scheduled.测试后测试表面一般要清洗和进行缺陷记录，特别是如果涂层过程被事先安排。9.0 Accepta nee Criteria 验收标准9.1按照ASME B16.34附录III-2.2锻件和滚压或轧制的材料最大可验收的（缺陷）显示如下：（a）线性显示（1）材料厚度小于13mm（ 0.5英寸）时，长为5mm（0.2英寸）。（2）材料厚度为1325mm（ 0.51英寸）时，长为10mm（0.4英寸）。（3）材料厚度大于25mm（ 1英寸）时，长为15mm（0.6英寸）。对
