EN 4179 (1) is the European Standard which 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) (2) in the aerospace manufacturing, service, maintenance and overhaul industries.
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(3) is not required by EN 4179 unless specified by local or regulatory requirements. The term Certification is used throughout EN 4179 as a substitute for the term 'approval'. Except when otherwise specified in the written practice, certification in accordance with EN 4179 includes operating approval.
EN 4179 applies to personnel using NDT methods to test and/or accept materials, products, components, assemblies or sub-assemblies. EN 4179 also applies to personnel directly responsible for the technical adequacy of the NDT methods used, who write NDT procedures and/or work instructions, who audit NDT facilities, or who provide technical NDT support or training.
EN 4179 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 another person certified to 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 EN 4179.
