EN 9138:2019
(Main)Aerospace Series - Quality Management Systems - Statistical Product - Acceptance Requirements
Aerospace Series - Quality Management Systems - Statistical Product - Acceptance Requirements
1.1 Purpose
This European standard establishes requirements when implementing statistical product acceptance methods to meet defined risk requirements. This standard also establishes the minimum content required to be covered in an organization’s documented procedures that govern their application of statistical product acceptance methods.
These general requirements and documented procedures apply the requirements of the EN 9100/EN 9110/EN 9120 quality management system standards, in addition to establishing requirements for retrievability, safety/critical characteristics, and quality parameters that protect the customer.
1.2 Application
This standard is applicable when invoked in a purchasing contract or specification, contractual document, customer agreement, or adopted by the organization. The purchase contract/agreement may or may not identify the appropriate EN 9138 clause(s) to be applied by the organization. All statistical methods of product acceptance require the use of Clause 4 and Clause 5.
To accept product produced:
- by individual lots, see Clause 6;
- under switching rules, see Clause 7;
- under process controls, see Clause 8; and
- by continuous sampling or special case methods, see Clause 9.
Luft- und Raumfahrt - Qualitätsmanagementsysteme - Statistische Anforderungen für die Produktannahme
1.1 Zweck
Diese Europäische Norm legt die Anforderungen für die Einführung statistischer Verfahren für die Pro-duktannahme zur Erfüllung festgelegter Risikoanforderungen fest. Diese Norm legt auch den erforderlichen Mindestinhalt fest, der in den dokumentierten Verfahren einer Organisation zu behandeln ist, die die Anwendung von statistischen Verfahren für die Produktannahme regeln.
Diese allgemeinen Anforderungen und dokumentierten Verfahren wenden die Anforderungen nach den Qualitätsmanagementsystemnormen EN 9100/EN 9110/EN 9120 an, zusätzlich zur Festlegung von Anfor-derungen an die Rückholbarkeit, Sicherheitsmerkmale/kritische Merkmale und Qualitätsparameter, die den Kunden schützen.
1.2 Anwendung
Diese Norm gilt, wenn sich ein Kaufvertrag oder eine Spezifikation, Vertragsdokument, Kundenvereinbarung darauf berufen oder sie von der Organisation übernommen wird. Der/Die Kaufvertrag/-vereinbarung darf den/die entsprechenden Abschnitt/Abschnitte nach EN 9138 benennen, der/die von der Organisation anzu¬wenden ist/sind oder dies unterlassen. Alle statistischen Verfahren für die Produktannahme erfordern die Anwendung von Abschnitt 4 und Abschnitt 5.
Um Produkte anzunehmen, die hergestellt wurden
- durch Einzellose, siehe Abschnitt 6,
- unter Variierung des Prüfumfangs, siehe Abschnitt 7,
- mit Prozessüberwachungen, siehe Abschnitt 8 und
- durch kontinuierliche Stichprobenahme oder Verfahren für Sonderfälle, siehe Abschnitt 9.

La présente norme s’applique lorsqu’elle est invoquée dans un contrat d’achat ou une spécification, un document contractuel, un contrat client ou qu’elle est adoptée par l’organisme. L’accord/contrat d’achat peut identifier ou non le(s) article(s) approprié(s) de l’EN 9138 à appliquer par l’organisme. Toutes les méthodes statistiques d’acceptation des produits exigent d’utiliser les Articles 4 et 5.
Pour accepter le produit fabriqué :
- en lots individuels, voir l’Article 6 ;
- conformément aux règles de modification du contrôle, voir l’Article 7 ;
- conformément aux maîtrises du processus, voir l’Article 8 ; et
- par échantillonnage continu ou à l’aide de méthodes pour cas particuliers, voir l’Article 9.
Aeronavtika - Sistemi vodenja kakovosti - Statistični proizvod - Zahteve za sprejem
Ta dokument določa zahteve pri izvajanju metod sprejemanja statističnega proizvoda za izpolnjevanje določenih zahtev glede tveganja. Standard prav tako določa minimalno vsebino, ki mora biti zajeta v dokumentiranih postopkih organizacije, ki ureja uporabo metod sprejemanja statističnega proizvoda. Te splošne zahteve in dokumentirani postopki upoštevajo zahteve iz standardov za sisteme vodenja kakovosti EN 9100/EN 9110/EN 9120, poleg tega pa določajo zahteve za dostopnost, varnostne/kritične značilnosti in parametre za kakovost, ki varujejo potrošnika. Uporaba: Ta standard se uporablja ob sklicevanju nanj v prodajni pogodbi ali specifikaciji, pogodbenem dokumentu, pogodbi z uporabnikom, ali če ga sprejme organizacija. V prodajni pogodbi/dogovoru bodo morda upoštevane ustrezne točke standarda EN 9138, ki jih mora organizacija uveljaviti. Vse statistične metode za sprejem proizvoda zahtevajo uporabo točk 4 in 5. Za sprejem izdelanega proizvoda: – po posameznih serijah, glej točko 6; – pod pravili za zamenjavo, glej točko 7; – pod nadzori procesov, glej točko 8; in – z neprekinjenim vzorčenjem ali po metodah posebnih primerov, glej točko 9.
