Description of BS EN 4179:2017 - TC 2020

1.1 PURPOSE This European Standard 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/CEI 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. 1.2 APPLICABILITY 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, or who 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 qualification or certification to this standard. 1.2.1 IMPLEMENTATION This standard addresses the use of a National Aerospace NDT Board (NANDTB). NANDTBs are only used as specified herein and it is not mandatory to have such a board for compliance with this document. Personnel certified to previous revisions of NAS410 or EN 4179 need not recertify to the requirements of this standard until their current certification expires. 1.3 COMMON METHODS This standard contains detailed requirements for the following common NDT methods: Liquid penetrant (PT) Magnetic particle (MT) Thermography (IRT) Shearography (ST) Eddy current (ET) Ultrasonic (UT) Radiography (RT) 1.3.1 OTHER METHODS When invoked by engineering, quality, cognizant engineering organization or prime contractor requirements, this standard applies to other current and emerging NDT methods used to determine the acceptability or suitability for intended service of a material, part, component, sub-assembly or assembly. Such methods may include, but are not limited to, acoustic emission, neutron radiography, leak testing and holography. The requirements for personnel training, experience, and examination for these other methods shall be established in accordance with 6.4 and shall be documented by the employer.
