Full Description ADOPTED_FROM:EN ISO 3452-1:2021 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.
磁粉和渗透还覆盖荧光方法。证书初次有效期为5年,5年期满后提供连续期间从事该项方法的工作证明可予以免考换发证书。首次取证后第10年参加复证考试予以复证。四、开设无损检测专业的高等院校有哪些?...
