Introduction
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.
1 Scope
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.

1 Področje uporabe
1.1 Namen
Ta dokument določa minimalne zahteve za kvalificiranje in certificiranje osebja, ki izvaja neporušitvene
preiskave (NDT), neporušitveno pregledovanje (NDI) ali neporušitveno vrednotenje (NDE) v letalski in
vesoljski proizvodnji, servisu, vzdrževanju in obnovi. V tem dokumentu je izraz neporušitvene preiskave
(NDT) uporabljen in obravnavan kot enakovreden neporušitvenemu pregledovanju in neporušitvenemu
vrednotenju (NDI in NDE).
V Evropi se izraz "odobritev" uporablja za pisno izjavo delodajalca, da posameznik izpolnjuje posebne
zahteve in ima operativno pooblastilo. Izraz "certifikat", kakor je opredeljen v točki 3.2, je v tem
dokumentu uporabljen kot nadomestek za izraz "odobritev". Razen če ni v pisnih postopkih določeno
drugače, certifikat v skladu s tem dokumentom vključuje tudi operativno pooblastilo.
