Requirement of UT Weld Qualification Examinations for Specimens Discontinuities in ISO 9712:2012

摘要: 描述了ISO 9712:2012标准中超声检测人员资格鉴定考试对焊缝超声考试试样不连续的要求, 与当前国内其他在用的标准规范要求进行了对比分析, 提出了作为用来考核考生能力的考试试样, 其本身应具有一定的可靠性和重复性的观点。在标准要求的基础上, 建立与国际接轨的高水准要求, 为最终实现无损检测人员资格证书的全球互认创造条件, 同时希望对国内同行资格鉴定机构提供有益的帮助。

Abstract: The requirement for specimen discontinuities in UT testing qualification examinations according to ISO 9712:2012 was descirbed in this article. Comparisons were made between this requirement and others used in local standards and norms. It was proposed that the examination specimens must be of high reliability and repeatability due to its role in qualifying the NDT candidates. Based on the requirement of ISO 9712:2012, a high level of requirement was built up to create conditions for promoting the global mutual recognition of NDT personnel. We hope this article can be of benefit for other local Qualficaiton Bodies.
