本国际标准规定了进行工业无损检测（NDT）人员资质认证的原则要求。 本国际标准中规定的系统也可以应用于其他无损检测方法或已建立的无损检测方法中的新技术，只要有完整的认证方案存在，并且该方法或技术被国际，区域或国家标准或新的无损检测方法或技术已被证明对认证机构满意是有效的。 该认证涵盖了以下一种或多种方法的熟练程度:a）声发射测试; b）涡流测试; c）红外热成像测试; d）泄漏检测（不包括液压试验）; e）磁性测试; f）渗透试验; g）放射检查; h）应变片测试; i）超声波检测; j）视觉测试（不包括在另一种无损检测方法的应用期间进行的直接的无辅助视觉测试和视觉测试）

This International Standard specifies requirements for principles for the qualification and certification of personnel who perform industrial non-destructive testing (NDT). The system specified in this International Standard can also apply to other NDT methods or to new techniques within an established NDT method, provided a comprehensive scheme of certification exists and the method or technique is covered by International, regional or national standards or the new NDT method or technique has been demonstrated to be effective to the satisfaction of the certification body. The certification covers proficiency in one or more of the following methods: a) acoustic emission testing; b) eddy current testing; c) infrared thermographic testing; d) leak testing (hydraulic pressure tests excluded); e) magnetic testing; f) penetrant testing; g) radiographic testing; h) strain gauge testing; i) ultrasonic testing; j) visual testing (direct unaided visual tests and visual tests carried out during the application of another NDT method are excluded).
