Aerospace series - Cables, electrical, aircraft use - Test methods - Part 701: Strippability and adherence of insulation to the conductor

This document specifies methods of measuring the strippability and adherence of the insulation to a conductor of a finished cable.
When a particular method is not specified in the detail product specification, method A is the default test method.
Method B is suitable for wires insulated with materials showing a low adhesion to the conductor due to the poor repeatability of the test method A with this type of wires.
It is intended to be used together with EN 3475 100.

Luft- und Raumfahrt - Elektrische Leitungen für Luftfahrtverwendung - Prüfverfahren - Teil 701: Abisolierbarkeit und Haftfestigkeit der Isolierung auf dem Leiter

Dieses Dokument legt Verfahren zur Bestimmung der Abisolierbarkeit und Haftfestigkeit der Isolierung auf einem Leiter einer fertigen Leitung fest.
Wenn kein bestimmtes Verfahren in der entsprechenden Produktspezifikation festgelegt ist, dann ist Verfahren A das standardmäßige Prüfverfahren.
Verfahren B ist für Drähte geeignet, die mit Werkstoffen isoliert sind, die eine niedrige Haftfestigkeit am Leiter aufweisen, da das Prüfverfahren A bei dieser Art von Drähten nur eine schlechte Wiederholpräzision aufweist.
Es ist vorgesehen, es zusammen mit EN 3475 100 anzuwenden.

Série aérospatiale - Câbles électriques à usage aéronautique - Méthodes d'essais - Partie 701 : Dénudabilité et adhérence de l'isolation sur le conducteur

Le présent document spécifie les méthodes pour mesurer la dénudabilité et l'adhérence de l'isolation sur un conducteur de câble fini.
Lorsqu'aucune méthode particulière n'est spécifiée dans la spécification de produit, la méthode A est la méthode par défaut.
La méthode B convient pour les fils isolés par des matériaux présentant une faible adhérence au conducteur en raison de la faible répétabilité de la méthode d'essai A pour ce type de fils.
Il est destiné à être utilisé conjointement avec l’EN 3475-100.

Overview

prEN 3475-701 - "Aerospace series - Cables, electrical, aircraft use - Test methods - Part 701: Strippability and adherence of insulation to the conductor" (CEN draft) specifies test methods to measure the strippability of cable jackets and the adherence (adhesion) of insulation to conductors for aerospace electrical cables. It is intended to be used together with EN 3475-100 and replaces EN 3475-701:2017 when adopted. The standard defines specimen preparation, test procedures, acceptance criteria and the default test approach for product specifications.

Key topics and requirements

  • Specimen preparation
    • Strippability tests use specimens taken from the finished cable.
    • Adherence tests use individual wires taken before integration into a finished cable.
    • Measurements should be made on samples directly from reels or coils with minimal deformation.
  • Strippability (jacket removal)
    • Stripping shall be achievable without difficulty over specified lengths (document references 5 mm for smaller sections and 8 mm for larger sections) using tools per EN 2812.
    • For screened cables, the stripping capability is characterized by the time to strip an 80 mm jacket section.
    • Maximum allowed stripping time: 40 s for a suitably skilled operator.
  • Adherence (insulation-to-conductor)
    • Two procedures are defined: Method A (default) and Method B (for low-adhesion insulating materials where Method A shows poor repeatability).
    • Test method: conductor is passed through a calibrated hole (conductor diameter + 0.05 mm) and subjected to increasing tensile force until sliding occurs.
    • Tensile speed: 100 ± 10 mm/min.
    • Method A: single measurement per specimen with minimum force defined in the product/technical specification.
    • Method B: typically three measurements per sample; if a measurement falls below the product limit, two additional measurements are taken and the median of five measurements must meet the specified minimum.
  • Acceptance
    • Minimum adherence forces and stripping performance are specified in the product or technical specification referenced by the purchaser/supplier.

Applications

  • Quality control and type-approval testing of aerospace electrical cables, wire harnesses and screened cables.
  • Ensuring reliable insulation adhesion for assembly processes (stripping, soldering, crimping) used in aircraft and aerospace systems.
  • Material selection and supplier qualification for cable manufacturers and aerospace OEMs.

Who should use this standard

  • Cable manufacturers, aerospace OEMs, wiring harness assemblers, test laboratories and quality engineers involved in aircraft electrical systems and component qualification.
