1.1 Purpose This document establishes the minimum requirements for the qualification and certification of personnel performing non-destructive testing (NDT), non-destructive inspection (NDI), or non-destructive evaluation (NDE) in the aerospace manufacturing, service, maintenance and overhaul industries. For the purposes of this document, 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 meets specific requirements and has operating approval. The term “certification” as defined in 3.2 is used throughout this document as a substitute for the term “approval”. Except when otherwise specified in the written practice, certification in accordance with this document includes operating approval. 1.2 Applicability 1.2.1 General This document applies to personnel using NDT methods to test and/or accept materials, products, components, assemblies or sub-assemblies. This document 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, or who provide technical NDT support or training. This document 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 person certified in the test method, do not require qualification or certification to this document. 1.2.2 Implementation This document addresses the use of a National Aerospace NDT Board (NANDTB). NANDTBs are only used as specified according to Annex C and it is not mandatory to have such a board for compliance with this document. Personnel certified to previous revisions of NAS 410 or EN 4179 need not recertify to the requirements of this document until their current certification expires. 1.3 Test Methods 1.3.1 Common test methods This document contains detailed requirements for the following common NDT methods: Eddy Current Testing (ET) Magnetic Particle Testing (MT) Penetrant Testing (PT) Radiographic Testing (RT) Thermographic Testing (TT) Ultrasonic Testing (UT) 1.3.2 Other test methods When invoked by engineering, quality, cognizant engineering organization or prime contractor requirements, this document applies to other current and emerging NDT methods used to determine the acceptability or suitability for intended service of a material, part, component, assembly or sub-assembly. Such test methods can include, but are not limited to, acoustic emission testing (AT), neutron radiography, leak testing, holography, and shearography. The requirements for personnel training, experience, and examination for these other test methods are established in accordance with 6.4 and are documented by the employer.
