Test Specimen No.: Demo. Report No.: NDE Level Ⅲ: AI: NJBST Co.,Ltd.QCD-014Rev.:0Page:3 of 8Title: PROCEDURE FOR MAGNETIC PARTICLE EXAMINATION 1. General 1.1 This procedure is applied to the magnetic particle examination of ferromagnetic materials and welds for ASME Code items. 1.2 The magnetic particle examination method is suitable for detecting cracks and other discontinuities on or near the surface in ferromagnetic materials. 1.3 This procedure is applied to wet continuous magnetization by yoke, which shall only be applied to detect discontinuities that are open to the surface of the part. 1.4 This procedure shall be demonstrated to the satisfaction of the AI prior to implementation. 2. Personnel 2.1 The NDE personnel who engage in magnetic particle examination shall be qualified and certified according to NJBST Co.,Ltd.’s “Written Practice for NDE Personnel Training, Examination, Qualification & Certification”(No.:QCD-011). 3. Description of Method 3.1 In principle, the magnetic particle examination method involves magnetizing an area to be examined, and ...
