Aerospace series - Use of regrinds and recycled materials in thermoplastic parts

This document gives guidance on the use of regrinds and recycled materials for thermoplastic parts for aerospace use.
This document does not apply to reinforced thermoplastic materials, such as short fibre-reinforced plastics, due to their distinct processing characteristics, material degradation concerns, and stringent aerospace performance requirements.
The intended manufacturing processes for these virgin/regrind blends include standard thermoplastic methods such as injection moulding, extrusion, and blow moulding, among others as appropriate to the application.

Luft- und Raumfahrt - Nutzung von Regranulaten und rezyklierten Materialien in thermoplastischen Bauteilen

Dieses Dokument gibt Leitlinien für die Verwendung von Regranulaten und Rezyklaten für thermoplastische
Teile zur Anwendung in der Luft- und Raumfahrt.
Dieses Dokument ist nicht anwendbar für verstärkte thermoplastische Werkstoffe wie z. B. kurzfaserverstärkte
Kunststoffe, aufgrund ihrer besonderen Verarbeitungseigenschaften, der Bedenken hinsichtlich der Werkstoffdegradation
und der strengen Leistungsanforderungen in der Luft- und Raumfahrt.
Zu den vorgesehenen Herstellungsverfahren für diese Mischungen aus Reinwerkstoff und Regranulat gehören
Standard-Thermoplastverfahren wie u. a. Spritzgießen, Extrusion und Blasformen, die für die jeweilige Anwendung
geeignet sind.

Série aérospatiale - Utilisation de matériaux rebroyés et recyclés dans les pièces thermoplastiques

Le présent document donne des lignes directrices sur l’utilisation de matériaux rebroyés et recyclés dans les pièces thermoplastiques pour les applications aérospatiales.
Ce document ne s'applique pas aux matériaux thermoplastiques renforcés, tels que les plastiques renforcés de fibres courtes, en raison de leurs caractéristiques de traitement distinctes, des préoccupations liées à la dégradation des matériaux et des exigences strictes en matière de performances aérospatiales.
Les procédés de fabrication prévus pour ces mélanges vierges/rebroyés comprennent les méthodes thermoplastiques standard telles que le moulage par injection, l'extrusion et le moulage par soufflage, entre autres, selon l'application.

This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee ASD-
STAN.
If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations
which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
