Aerospace series - Qualification and approval of personnel for nondestructive testing

Edition date: 2026-02-04
In Force
Available languages: German, English
Summary: 1.1 General This document 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 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 has met specific requirements and has operating approval. The term "certification" as defined in 3.3 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 Purpose 1.2.1 Applicability This document applies to personnel who: - use NDT methods or equipment to test and/or accept materials, products, components, assemblies or sub-assemblies; - are directly responsible for the technical adequacy of the NDT methods and equipment used; - operate automatic interpretation or evaluation systems; - approve NDT procedures or work instructions; - audit NDT facilities; or - 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. See Clause 8 regarding applicability to personnel performing specialized inspections using certain direct readout instruments. 1.2.2 Implementation This document addresses the use of a National Aerospace NDT Board (NANDTB). NANDTBs are only used as specified per Annex C and it is not mandatory to have such a board for compliance with this document. Personnel certified to previous revisions of NAS410/EN 4179 need not recertify to the requirements of this document until their current certification expires. 1.2.3 NDT methods This document contains detailed requirements for the following NDT methods: eddy current testing (ET) penetrant testing (PT) magnetic particle testing (MT) radiographic testing (RT) shearography testing (ST) thermographic testing (IRT) ultrasonic testing (UT) When invoked by engineering, quality, cognizant engineering organization or prime contractor requirements, this document applies to other NDT methods used to determine the acceptability or suitability for intended service of a material, part, component, sub-assembly or assembly. Such methods can include, but are not limited to, acoustic emission, neutron radiography, leak testing, and holography.

1.1 Généralités Le présent document établit les exigences minimales pour la qualification et la certification de personnel réalisant des essais non destructifs (END), des contrôles non destructifs (CND) ou des évaluations non destructives (ÉND) dans la fabrication, les services, la maintenance et la réparation de l’industrie aérospatiale. Pour les besoins du présent document, le terme END sera utilisé et il sera considéré comme l’équivalent de CND et ÉND. En Europe, le terme « agrément » est utilisé pour désigner une attestation écrite par un employeur déclarant qu’une personne a satisfait à des exigences spécifiques et qu’elle est titulaire de l’agrément d’exploitation. Le terme « certification » tel que défini en 3.3 est utilisé tout au long du présent document en remplacement du terme « agrément ». Sauf spécification contraire dans la procédure interne d'application, la certification conformément au présent document inclut l’agrément d’exploitation. 1.2 Objet 1.2.1 Applicabilité Le présent document s'applique au personnel qui : — utilise des méthodes ou des équipements END pour les essais et/ou la réception de matériaux, produits, composants, ensembles ou sous-ensembles ; — est directement responsable de l'adéquation technique des méthodes et équipements END utilisés ; — utilise des systèmes d'interprétation ou d'évaluation automatiques ; — approuve des procédures ou des instructions de travail END ; — audite des installations END ; ou — fournit de l'assistance ou de la formation aux techniques END. Ce document ne s'applique pas aux personnes qui n’ont qu’une autorité administrative ou de surveillance du personnel END, ou au personnel de recherche chargé de développer une technologie END pour mise en œuvre et approbation ultérieure par une personne certifiée niveau 3. Voir l’Article 8 concernant l’applicabilité au personnel réalisant des contrôles spécialisés à l’aide d’instruments de mesure à lecture directe.

1.1 Allgemeines Dieses Dokument legt die Mindestanforderungen an die Qualifizierung und Zertifizierung von Personal fest, das in der Luft- und Raumfahrtindustrie in den Bereichen Herstellung, Dienstleistung, Instandhaltung und Überholung zerstörungsfreie Prüfungen (ZfP), zerstörungsfreie Überwachungen (ZfÜ) oder zerstörungsfreie Beurteilungen (ZfB) durchführt. Für die Anwendung dieses Dokuments wird der Begriff ZfP verwendet und gilt als gleichbedeutend mit ZfÜ und ZfB. In Europa wird der Begriff „Zulassung“ verwendet, um eine schriftliche Bestätigung eines Arbeitgebers zu bezeichnen, dass eine Person besondere Anforderungen erfüllt hat und über eine Handlungsbevollmächtigung verfügt. Der Begriff „Zertifizierung“, wie in 3.3 festgelegt, wird in diesem Dokument durchgängig anstelle des Begriffs „Zulassung“ verwendet. Wenn nicht anders in der Zulassungsvorschrift festgelegt, schließt Zertifizierung nach diesem Dokument eine Handlungsbevollmächtigung ein. 1.2 Zweck 1.2.1 Anwendbarkeit Dieses Dokument ist anwendbar für Personal, das:  ZfP Verfahren oder Geräte für die Prüfung und/oder Annahme von Werkstoffen, Produkten, Bauteilen, Baugruppen oder Bauteil-Untergruppen anwendet;  direkt für die technische Eignung der angewendeten ZfP Verfahren und Geräte verantwortlich ist;  Systeme zur automatischen Auslegung oder Beurteilung betreibt;  ZfP Verfahren oder Prüfanweisungen genehmigt;  ZfP Einrichtungen auditiert; oder  für die technische ZfP Unterstützung oder Ausbildung zuständig ist. Dieses Dokument ist nicht anwendbar für Personen, die lediglich administrative oder überwachende Befugnisse über ZfP Personal ausüben, oder für Forschungspersonal, das ZfP Technologien für die anschließende Umsetzung und Zulassung durch ZfP Personal der Stufe 3 entwickelt. Siehe Abschnitt 8 hinsichtlich der Anwendbarkeit für Personal, welches spezielle Inspektionen mithilfe von bestimmten direkt anzeigenden Messgeräten vornimmt. 1.2.2 Umsetzung Dieses Dokument erwähnt den Einsatz eines Nationalen Luft- und Raumfahrt-ZfP-Komitees (NANDTB). NANDTB werden nur wie nach Anhang C festgelegt verwendet; für die Übereinstimmung mit den Anforderungen dieses Dokuments ist ein solches Komitee jedoch nicht zwingend erforderlich. Personal, das nach früheren Überarbeitungen von NAS410/EN 4179 zertifiziert ist, braucht sich nicht erneut nach den Anforderungen dieses Dokuments zertifizieren zu lassen, bis seine gegenwärtig gültige Zertifizierung erlischt. 1.2.3 ZfP Verfahren Dieses Dokument enthält ausführliche Anforderungen an folgende ZfP Verfahren: Wirbelstromprüfung (ET) Penetrationsprüfung (PT) Magnetpulverprüfung (MT) Durchstrahlungsprüfung (RT) Shearographieprüfung (ST) Thermographische Prüfung (IRT) Ultraschallprüfung (UT) Wenn es die Technik, die Qualität, die zuständige Planungsorganisation oder die Anforderungen des Hauptauftragnehmers erfordern, gilt dieses Dokument auch für weitere ZfP Verfahren, die angewendet werden, um die Annehmbarkeit oder Eignung für die beabsichtigte Funktion eines Werkstoffes, Teiles, Bauteiles, einer Unterbaugruppe oder Baugruppe zu ermitteln. Derartige Verfahren können unter anderem die Schallemissionsprüfung, die Durchstrahlungsprüfung mit Neutronen, die Dichtheitsprüfung und die Holographie umfassen, sind aber nicht darauf beschränkt.
