Overview

EN 10244-5:2001 is the CEN European Standard that specifies requirements and test methods for nickel coatings on steel wire and steel wire products (round or other cross-sections). It covers material composition, coating mass requirements, sampling and test procedures, and adherence testing for nickel-plated steel wire. The standard applies to wires with nickel applied by electrolytic deposition, either before drawing or after final sizing.

Key Topics

• Scope and definition
  • Defines “wire with nickel coating” as steel wire plated by electrolytic nickel deposition.
• Material requirements
  • Coating must be pure, non‑alloy nickel; impurities limited to a maximum of 2%.
• Mass of coating
  • Coating mass (when required) is agreed at enquiry/order or specified by the product standard.
• Sampling and test conditions
  • Sample length must be sufficient to perform all required tests, per general rules in EN 10244‑1.
• Determination of coating mass
  • Two accepted methods:
    • Gravimetric method: degrease (if needed), weigh to 0.1 mg accuracy, strip nickel in concentrated nitric acid (density 1.4 at 20 °C), reweigh and calculate mass following EN 10244‑1 procedures.
    • Atomic absorption spectrometry (AAS): determines nickel quantity in pickling solution; recommended when gravimetric accuracy is reduced by aggressive stripping.
  • Note: gravimetric errors can vary with substrate steel composition; AAS offers higher accuracy.
• Adherence test
  • Per EN 10244‑1: bend the wire around a mandrel with a diameter three times the wire diameter; nickel coating must show no flaking.

Applications

• Intended for manufacturers, suppliers and quality labs involved in nickel-plated steel wire production and testing.
• Useful to engineers, specifiers and purchasers who require verified coating mass, adhesion and material purity for applications such as corrosion resistance, electrical contacts, decorative wire, fasteners and industrial components where nickel plating properties are critical.
• Ensures repeatable, comparable test results and contractual clarity when ordering nickel-coated steel wire.

Related Standards

• EN 10244-1 - Steel wire and wire products - Non‑ferrous metallic coatings on steel wire - Part 1: General principles
• EN 10244-4 - Part 4: Tin coatings
• EN 10244 series (Parts 1–6) covering other non‑ferrous coatings (zinc, aluminium, tin, nickel, copper/bronze/brass)

Compliance with EN 10244-5:2001 provides a clear technical basis for specifying nickel coatings on steel wire and for consistent laboratory testing and quality control.
