Copper and copper alloys - Determination of spiral elongation number

This European Standard specifies a method for performing the spiral elongation test on high purity copper drawing stock conforming to EN 1977, grade Cu-ETP1 (CW003A). The method has been designed for testing high purity copper sampled at the drawing stock stage. It is not relevant for assessing the quality of copper wire selected at a later stage of processing.

Kupfer und Kupferlegierungen - Bestimmung der Spiralverlängerungszahl

Diese Europäische Norm legt ein Verfahren zur Durchführung der Spiralverlängerungsprüfung an Vordraht aus hochreinem Kupfer der Sorte Cu-ETP1 (CW003A) in Übereinstimmung mit EN 1977 fest. Das Verfahren ist zum Prüfen von hochreinem Kupfer entworfen worden, das dem Vordraht als Probe entnommen wird. Das Verfahren gilt nicht für die Beurteilung der Qualität von Drähten aus Kupfer, die aus einer nachfolgenden Bearbeitungsstufe entnommen wurden.

Cuivre et alliages de cuivre - Détermination de l'indice d'allongement par spirale

La présente norme européenne spécifie une méthode pour réaliser l'essai de l'allongement par spirale sur du fil machine en cuivre de très grande pureté, conformément à l'EN 1977, de qualité Cu-ETP1 (CW003A). La méthode a été conçue en vue de soumettre à l'essai des échantillons en cuivre de très grande pureté prélevés au stade du fil machine. Il ne convient donc pas pour évaluer la qualité d'un fil de cuivre prélevé à un stade ultérieur de la production.

Overview

EN 12893:2000 (CEN) specifies a method to determine the spiral elongation number of high‑purity copper drawing stock. The scope covers material sampled at the drawing stock stage and is specifically intended for copper conforming to EN 1977, grade Cu‑ETP1 (CW003A). The method is designed to evaluate drawing-stage ductility and is not relevant for assessing copper wire selected at later stages of processing.

This standard supports consistent assessment of drawing stock quality and provides a harmonized approach for laboratories and manufacturers when reporting spiral elongation results.

Key Topics

  • Scope and applicability: Test method for high‑purity copper drawing stock (Cu‑ETP1) sampled at the drawing stock stage.
  • Purpose: Measure spiral elongation number to characterise ductility relevant to wire drawing processes.
  • Sampling context: Intended for drawing stock stage sampling; results should not be used to infer performance of fully processed wire.
  • Standard references: Relates directly to EN 1977, which defines requirements for copper drawing stock.

Applications

EN 12893:2000 is practically valuable for manufacturers, quality laboratories, and procurement teams involved in copper wire supply chains. Typical uses include:

  • Quality control: Verify that incoming drawing stock meets ductility expectations before wire drawing.
  • Supplier acceptance: Establish consistent acceptance criteria for batches of Cu‑ETP1 drawing stock.
  • Process planning: Inform drawing parameters by providing a reproducible measure of elongation behaviour at the drawing stock stage.
  • Traceability and reporting: Provide standardized test results for technical documentation and compliance checks.

Benefits of using the standard method:

  • Harmonised testing approach across laboratories and suppliers
  • Improved comparability of results for procurement and quality assurance
  • Reduced risk of drawing failures by testing the appropriate production stage

Related Standards

  • EN 1977 - referenced within EN 12893:2000 as the specification for copper drawing stock (Cu‑ETP1).
  • CEN framework - EN 12893:2000 is published under CEN and intended to work alongside other European copper and wire product standards.

For organizations handling copper drawing stock, EN 12893:2000 offers a targeted, repeatable method to assess spiral elongation at the drawing stage, helping to ensure reliable wire‑drawing performance and consistent material quality.
