(Main)Aerospace series - Qualification and approval of personnel for non-destructive testing
Aerospace series - Qualification and approval of personnel for non-destructive testing
1.1 Purpose
This standard 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
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 not required by this
standard unless specified by local or regulatory requirements. The term certification as defined in paragraph
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 write 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.

Aeronavtika - Usposobljenost in odobritev osebja za neporušitveno preskušanje
Ta evropski standard vzpostavlja minimalne zahteve za usposobljenost in certifikacijo osebja, ki opravlja neporušitveno preskušanje (NDT), neporušitvene preglede (NDI) ali neporušitveno ovrednotenje (NDE) v aeronavtiki, v proizvodnem, servisnem, vzdrževalnem in obnovitvenem sektorju. Za namene tega standarda se uporablja izraz NDT, ki se šteje kot enakovreden izrazoma NDI in NDE. V Evropi se uporablja izraz »odobritev«, ki označuje pisno izjavo delodajalca, da je posameznik izpolnil posebne zahteve in ima operativno dovoljenje. Ta standard ne zahteva certifikacije po EN ISO/IEC 17024, razen če tako določajo lokalni ali pravni predpisi. Izraz »certifikacija«, kot je definiran v točki 3.1, se uporablja skozi celoten standard kot nadomestna beseda za izraz »odobritev«. Razen kadar je drugače določeno v pisni obliki, certifikacija v skladu s tem standardom vključuje operativno dovoljenje.

1 Scope 1.1 Purpose This European Standard 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 standard, the term NDT is used and is 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 not required by this standard unless 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 write 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. 1.3 Implementation This standard addresses the use of a National Aerospace NDT Board (NANDTB). NANTDBs 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 NAS 410 or EN 4179 need not recertify to the requirements of this standard until their current certification expires. 1.4 Common methods This standard contains detailed requirements for the following common NDT methods: Penetrant testing (PT) Magnetic testing (MT) Eddy current testing (ET) Ultrasonic testing (UT) Radiographic testing (RT) Thermographic testing (TT) Shearographic testing (ST) 1.5 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 SIST EN 4179:2010
EN 4179:2009 (E) 5 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 should be established in accordance with 6.4 and documented by the employer. 2 Normative references 2.1 Standards The following referenced documents are indispensable for the application of this document.

In addition, the prime contractor shall be responsible for compliance to this standard by their suppliers and sub-contractors. Employers using outside agencies shall be responsible for assuring that the appropriate requirements of this standard are met. The employer is solely responsible for the certification of its employees and cannot certify for another employer. Individuals cannot qualify themselves. Self-employed individuals may certify themselves provided they have a written practice and have been qualified to the requirements of this standard by another individual certified to Level 3 in accordance with this standard. 4.5 Responsible Level 3 The employer shall identify in writing a “Responsible Level 3” to act on its behalf in matters regarding the NDT qualification and certification process. The Responsible Level 3 shall be certified in accordance with this standard as a Level 3 in one or more NDT methods and shall have a thorough knowledge of the written instructions, codes, specifications and standards used by the employer. He/she shall also have a thorough knowledge of the materials, components, product technologies, NDT methods and NDT techniques used by the employer. Additional Level 3 Examiners as defined in this standard may be identified and delegated in writing as necessary to provide coverage for all methods used by the employer. The Responsible Level 3 may be an outside agency but in this case he/she can only qualify personnel, as only the employer can certify personnel. 4.5.1 When a national aerospace NDT board (NANDTB) is not used When a NANDTB is not used, the Responsible Level 3 shall be responsible for the implementation of this standard and the overall administration of the qualification and certification program. 4.5.2 When a national aerospace NDT board (NANDTB) is used When a NANDTB is used, it shall administer procedures for qualification and certification of NDT personnel in accordance with the requirements of this standard. It is entitled, in conjunction with the employer, to recognize SIST EN 4179:2010
EN 4179:2009 (E) 11 equivalencies of qualification and certification, and may be requested to provide general guidelines in accordance with this standard regarding facilities for NDT training, course outlines, examination questions and examination procedures. The procedures of the NANDTB shall clearly define what role and tasks, as applicable, are to be performed by the Responsible Level 3. The employer shall designate a Responsible Level 3 in accordance with 4.5. The Responsible Level 3 is designated by the employer to ensure the requirements of this standard and NANDTB procedures are met and to act on behalf of the employer for those tasks designated here-in for the Responsible Level 3. NANDTBs described in this standard apply solely to boards meeting the definition of 3.18 of this standard. Other agencies performing examination, qualification and/or training activities shall be considered outside agencies as defined in 3.22. For countries where no NANDTB exists, countries may use the services of other NANDTBs, but are not required to do so. 4.6 Outside agency An employer may use a Level 3 certified in accordance with this standard from an outside agency to develop a certification program, act as the Responsible Level 3, examine NDT personnel or perform any other qualification or certification Level 3 function. An outside agency may qualify, but not certify personnel. The employer shall document the suitability of any outside agency selected to perform any function in meeting the requirements of this standard. This documentation shall be of sufficient detail to justify the outside agency’s ability to perform the required Level 3 function(s). 5 Qualification and certification Levels 5.1 Levels of qualification and certification The four basic levels of certification are Level 1-Limited, Level 1, Level 2 and Level 3. The employer may subdivide, add or limit levels as appropriate, but cannot eliminate or reduce the minimum requirements for each level. If the employer does not wish to use all of the following levels, those levels to be used shall be documented in the employer’s written practice. Where other variations or subdivisions are implemented, the requirements and responsibilities shall also be detailed in the employer’s written practice. NDT personnel shall not independently perform the functions listed in 5.1.2, 5.1.3, 5.1.4 and 5.1.5 if not certified to the appropriate level in the applicable technique/method. 5.1.1 Trainee An
