EN 4179:2017 (E) 6 1. SCOPE 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) SIST EN 4179:2017



EN 4179:2017 (E) 7 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. 2. REFERENCE DOCUMENTS 2.1 STANDARDS The following documents are referenced in this standard: EN 4179, Aerospace Series - "Qualification and Approval of Personnel for Nondestructive Testing'' ISO 18490 – Nondestructive Testing – Evaluation of Vision Acuity of NDT Personnel NAS 410 - "Certification and Qualification of Nondestructive Test Personnel" EN ISO/CEI 17024, Conformity Assessment- General Requirements for Bodies Operating Certification of Persons ISO 9712 - Non-Destructive Testing - Qualification and Certification of Personnel 2.2 ORDER OF PRECEDENCE In the event of a conflict between the text of this document and the references cited herein, the requirements of this document take precedence.
Nothing in this document supersedes applicable laws and regulations unless a specific exemption has been obtained. 3. DEFINITIONS AS APPLIED TO THIS STANDARD 3.1 CERTIFICATION A written statement by an employer that an individual has met the applicable requirements of this standard.
3.2 CLOSED BOOK EXAMINATION An examination administered without access to any reference materials. 3.3 COGNIZANT ENGINEERING ORGANIZATION The engineering or NDT organization of the prime contractor, OEM (Original Equipment Manufacturer), or end user authorized to make NDT-related decisions and give NDT-related approvals.

EN 4179:2017 (E) 8 3.4 DIRECT OBSERVATION Direct observation is when the observer is able to come to the immediate aid of the trainee and remains within a distance that permits uninterrupted, unaided visual and verbal contact with the trainee. 3.5 DIRECT READOUT INSTRUMENT Instruments that physically display measurements in dimensional or electrical units (e.g. inches, millimeters or %IACS.) either as digital readout or an analog display, such as a scale/pointer configuration and do not require special skills or knowledge to set up the instrument and do not involve adjusting signal displays such as gates, delays, gain, or phase to obtain measurements. For example, common direct readout instruments include basic ultrasonic thickness gauges without an oscilloscope display, and eddy current coating thickness gauges. 3.6 DOCUMENTED The condition of being recorded in written or electronic form. 3.7 EMPLOYER An organization employing or contracting the services of one or more individuals who perform NDT. Self-employed individuals are included in this definition. 3.8 EVALUATION A review following interpretation of the indications noted during an NDT inspection to determine whether the indications meet specified acceptance criteria or to determine the significance of the indication. 3.9 EXAMINATION Formal, controlled, documented testing conducted in accordance with a documented written practice to verify a candidate’s visual capability, skill or knowledge of an NDT method.
3.10 EXAMINER A Level 3 certified to this standard and designated by the Responsible Level 3 to administer all or part of the qualification process in the NDT method(s) in which the Examiner is certified.
3.11 EXPERIENCE Actual performance of an NDT method conducted in the work environment resulting in the acquisition of knowledge and skill.
This does not include formal classroom training, but may include laboratory and on-the-job training as defined by the employer’s written practice.
