Aerospace series - Cables, electrical, aircraft use - Test methods - Part 701: Strippability and adherence of insulation to the conductor
This European Standard 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 shall be used.
Method B is recommended 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 shall 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
Diese Europäische Norm legt Verfahren zur Bestimmung der Abisolierbarkeit und Haftfestigkeit der Isolie-rung auf einem Leiter von fertigen Leitungen fest.
Wenn kein bestimmtes Verfahren in der entsprechenden Produktspezifikation angegeben ist, dann ist das Verfahren A anzuwenden.
Verfahren B ist für Drähte empfohlen, 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.
Die Norm ist 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
La présente norme définit les méthodes pour mesurer la dénudabilité et l'adhérence de l'isolation sur le conducteur de câble terminé.
Lorsqu'aucune méthode particulière n'est spécifiée dans la norme de produit individuelle, la Méthode A doit être utilisée.
La Méthode B est recommandée 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.
Elle doit être utilisée conjointement avec l'EN 3475-100.

Ta evropski standard določa metode za merjenje odstranljivosti in oprijemljivosti izolacije vodnika dokončanega kabla.
Če v podrobni specifikaciji proizvoda ni navedena določena metoda, se uporabi metoda A.
Metoda B se priporoča za žice, izolirane z materiali, ki prikazujejo nizko oprijemljivost z vodnikom,
in sicer zaradi slabe ponovljivosti preskusa A s tem tipom žice.
Uporabljati ga je treba skupaj s standardom EN 3475-100.

Overview
EN 3475-701:2017 (CEN) specifies standardized test methods to measure the strippability of cable jackets and the adherence of insulation to conductors for finished aircraft cables. The standard defines specimen preparation, two test methods for adherence (Method A and Method B), and requirements for acceptable performance. It is intended to be used together with EN 3475-100 and references EN 2812 for stripping tools.
Key practical facts:
- Default method: Method A is the default when the detail product specification does not require otherwise.
- When to use Method B: Recommended for wires with low adhesion to the conductor because Method A can show poor repeatability for such materials.
- Reference tests: Use EN 3475-100 for general test practices and EN 2812 for stripping tool specifications.
Key Topics
- Specimen preparation: Samples shall be measured directly from a reel or coil with minimal deformation. Stripping shall be performed at the two ends of each specimen using tools conforming to EN 2812.
- Stripping lengths: For insulation stripping properties, the insulation must be stripped over 5 mm for cables up to 5 mm2 and over 8 mm for cables greater than 5 mm2 at each specimen end.
- Adherence test layouts:
- Method A: insulation cut around the periphery at 5 mm and 30 mm from one end (for sizes up to 5 mm2) and the remaining insulation left on the conductor.
- Method B: insulation cut at 5 mm and 55 mm from one end; required when low adhesion materials are present.
- Force test procedure: For both methods the conductor is passed through a calibrated hole of diameter (conductor diameter + 0,05 mm) and subjected to an increasing tensile force until sliding occurs. The tensile speed is (100 ± 10) mm/min.
- Measurement rules: Method B requires three initial measurements per sample; if one measurement is below the product limit, two additional measurements are taken and the median of five measurements is used.
- Stripping capability timing: For screened cables, the jacket stripping operation shall not exceed 40 s for a suitably skilled operator when stripping an 80 mm length.
Applications
This standard is essential for aerospace and defense manufacturers, cable designers, quality engineers, and test laboratories involved in aircraft wiring. It ensures:
- Consistent evaluation of insulation adhesion for reliable electrical and mechanical performance
- Informed selection between Method A and Method B for materials with different adhesion characteristics
- Compliance evidence for product specifications and procurement requirements
