NAS 410修订版。5规定了航空航天制造、服务、维护和大修行业中进行无损检测（NDT）、无损检测（NDI）或无损评估（NDE）的人员资格和认证的最低要求。在本标准中，将使用术语NDT，并将其视为等同于NDI和NDE。在欧洲，“批准”一词用于表示雇主的书面声明，表明个人已满足特定要求并获得运营批准。当当地或监管要求规定时，本标准要求按照EN ISO/IEC 17024进行认证。第3条中定义的术语“认证”。 1在本标准中用作术语“批准”的替代品除非书面实践中另有规定，否则符合本标准的认证包括运营批准。本标准适用于使用无损检测方法测试和/或验收材料、产品、部件、组件或子组件的人员。本标准也适用于以下人员:直接负责所用无损检测方法的技术充分性、批准无损检测程序和/或工作说明、审核无损检测设施或提供无损检测技术支持或培训的人员。本标准不适用于仅对无损检测人员拥有行政或监督权限的个人，也不适用于开发无损检测技术的研究人员，以供后续实施，并获得认证级别3的批准。 使用本方法中认证的3级直接读数仪器进行专业检查的人员不需要本标准的资格或认证。

NAS 410 Rev. 5 establishes the minimum requirements for the qualification and certification of personnel performing nondestructive testing (NDT), nondestructive inspection (NDI), or nondestructive evaluation (NDE) in the aerospace manufacturing, service, maintenance and overhaul industries. For the purposes of this standard, the term NDT will be used and will be considered equivalent to NDI and NDE.In Europe, the term "approval" is used to denote a written statement by an employer that an individual has met specific requirements and has operating approval. Certification per EN ISO/IEC 17024 is required by this standard when specified by local or regulatory requirements. The term "certification" as defined in 3.1 is used throughout this standard as a substitute for the term "approval." Except when otherwise specified in the written practice, certification in accordance with this standard includes operating approval.This standard applies to personnel using NDT methods to test and/or accept materials, products, components, assemblies or sub-assemblies. This standard also applies to personnel:directly responsible for the technical adequacy of the NDT methods used,who approve NDT procedures and/or work instructions,who audit NDT facilities, orwho provide technical NDT support or training.This standard does not apply to individuals who only have administrative or supervisory authority over NDT personnel or to research personnel developing NDT technology for subsequent implementation and approval by a certified Level 3. Personnel performing specialized inspections using certain direct readout instruments as determined by a Level 3 certified in the method, do not require qualifications or certification to this standard.
