Aerospace series - Acceptance of the cosmetic variations in appearance of aircraft cabin parts

This standard defines surfaces on visible components in the aircraft cabin. Surfaces will be considered under the aspects of technical feasibility of the industrial design.
This standard is a guideline between airlines, supplier and OEMs with regard to cosmetic issues.
This document aims to:
a) Provide the supplier with quality criteria, which need to be met during the production, testing- and quality-inspection-process,
b) Guide airline-, OEM- and supplier-quality assurance with a description of cosmetic standards for following inspections:
- Supplier internal QA inspection;
- First article inspection;
- Source inspection;
- Incoming inspection;
- Final assembly line cabin inspection.

Luft- und Raumfahrt - Akzeptanz von kosmetischen Qualitätsabweichungen bei Flugzeug-Kabinenbauteilen

La présente norme européenne définit les surfaces sur des composants visibles dans la cabine d'avion. Les surfaces seront examinées en tenant compte des aspects de faisabilité technique de la conception industrielle.
La présente Norme constitue une ligne directrice s'adressant aux compagnies aériennes, au fournisseur et aux fabricants d'équipement d'origine (FEO) en ce qui concerne les questions d'esthétisme.
Le présent document vise à :
a)   Donner au fournisseur des critères de qualité, qui devront être remplis pendant le processus de production, d'essai et d'inspection de la qualité,
b)   Orienter l'assurance qualité d'une compagnie aérienne, d'un FEO et d'un fournisseur par la description de normes d'esthétisme pour les inspections suivantes :
-   Inspection d'assurance qualité interne du fournisseur ;
-   Inspection du premier article ;
-   Inspection à la source ;
-   Inspection à livraison ;
-   Inspection de la cabine sur la chaîne de montage final.

Aeronavtika - Odobravanje kozmetičnih odstopanj videza sestavnih delov letalske kabine

Ta standard določa površine na vidnih delih letalske kabine. Površine bodo obravnavane z vidika tehnične izvedljivosti industrijske zasnove.
Ta standard je vodilo za letalske družbe, dobavitelja in proizvajalce originalne opreme glede kozmetičnih elementov.
Cilj tega dokumenta je opredeliti:
a) merila kakovosti za dobavitelja, ki morajo biti izpolnjena med proizvodnjo, preskušanjem in izvajanjem postopkov preverjanja kakovosti;
b) smernice za letalske družbe, proizvajalca originalne opreme in dobavitelja pri zagotavljanju kakovosti z opisom kozmetičnih standardov pri
naslednjih pregledih:
 interno preverjanje kakovosti dobavitelja;
 prvi pregled artiklov;
 preverjanje vira;
 dohodni pregled;
 končni pregled serijsko izdelane kabine.
