Overview

EN 13601:2021 - "Copper and copper alloys - Copper rod, bar and wire for general electrical purposes" is the CEN European standard that defines material composition, required properties (including electrical properties), dimensional tolerances and form tolerances for copper rod, bar and wire intended for electrical use. It covers sampling procedures and test methods to verify conformity. Size ranges include round, square and hexagonal rod (2 mm to 160 mm), bar (thickness 2–40 mm; width 3–250 mm) and various wire cross-sections (diameters/widths 2–25 mm; thicknesses 0.5–12 mm; widths 1–250 mm).

Key Topics and Requirements

• Material composition and designation: Defines how copper and copper-alloy types are identified (symbol or number) and grouped for electrical use.
• Material condition: Uses standard condition codes (D, H..., R...) to denote cold-worked, hardness-specified or tensile-specified conditions.
• Mechanical and electrical properties: Specifies tensile, hardness, bending characteristics and electrical resistivity requirements relevant to electrical performance.
• Freedom from hydrogen embrittlement: Includes procedures and adds specific alloys to the requirement.
• Dimensions and tolerances: Detailed limits for diameters, widths, thicknesses, corner configurations and mass tolerances for rod, bar and wire.
• Form tolerances: Requirements and maximums for twist, straightness and flatness (including wire in coils).
• Sampling and test methods: Sampling procedures and test methods for analysis, tensile test, Brinell/Vickers hardness, bend test, electrical resistivity (IEC 60468) and hydrogen embrittlement (EN ISO 2626).
• Conformity documentation: Rules for declaration of conformity, inspection documentation, marking, packaging and labelling.

Practical Applications

EN 13601:2021 is used wherever reliable copper products with specified electrical performance are required:

• Manufacturing of busbars, terminals, connectors, switchgear components and contact strips
• Electrical engineering components for distribution and power systems
• Suppliers and mills producing rod, bar and wire for general electrical purposes
• Quality control and laboratory testing to verify compliance with electrical resistivity and mechanical performance

When ordering or specifying copper rod/bar/wire for electrical use, include the EN 13601 product designation (product type, EN number, material designation, material condition and cross-sectional shape) and any required test/inspection options.

Who Should Use This Standard

• Copper product manufacturers and distributors
• Design and electrical engineers specifying conductive components
• Quality inspectors, test laboratories and procurement teams
• Regulatory and certification bodies verifying compliance

Related Standards

• EN 13602 - drawn round copper wire for manufacture of electrical conductors
• EN 13599, EN 13600, EN 13604, EN 13605 - other copper products for electrical purposes

Keywords: EN 13601:2021, copper rod, copper bar, copper wire, copper and copper alloys, electrical properties, tolerances, test methods, sampling, electrical conductors.

4.1.2 Symbol
The material symbol designation is based on the designation system given in ISO 1190-1.
NOTE Although material symbol designations used in this document might be the same as those in other
standards using the designation system given in ISO 1190-1, the detailed composition requirements are not
necessarily the same.
4.1.3 Number
The material number designation is in accordance with the system given in EN 1412.
4.2 Material condition
