Overview

EN 60851-3:2009/A1:2013 (IEC 60851-3:2009/A1:2013) is a CENELEC/IEC amendment that updates test methods for the mechanical properties of winding wires. Published as Amendment A1 in 2013, the document clarifies procedures and apparatus for measuring properties such as friction, surface smoothness and mechanical behaviour relevant to enamelled and magnet wires.

This standard is used by manufacturers, test labs and purchasers to ensure consistent material quality, reliable winding performance and effective lubricant application.

Key Topics

• Scope and status: Amendment A1 modifies EN 60851-3:2009 and was approved by CENELEC on 2013-09-04; it is aligned with IEC TC 55 "Winding wires".
• Dynamic coefficient of friction (Test C): Detailed method for enamelled round wires with nominal conductor diameters from 0,050 mm to 1,600 mm. The test quantifies the combined effect of lubrication and surface film smoothness.
• Test equipment and measurement:
  • Wire is pulled at 15 ± 1,5 m/min over a test bed using a motor-driven take-up.
  • A load block with mounted synthetic sapphires contacts the wire; friction generates a longitudinal force measured by a load cell or LVDT and recorded by a microprocessor/computer.
  • Typical force transducer range: 0–500 grams-force; data sets of about 1 000 points are captured for statistical analysis (min, max, mean, standard deviation).
• Specimen preparation and cleanliness: Wire should be de-reeled with minimal extraneous contact; test surfaces must be cleaned with a solvent that removes lubricants without leaving residues.
• Load selection: The standard provides load weight guidance by conductor diameter to compute the dynamic coefficient of friction μ = Fd / L (force divided by test load). Example load ranges available are 100–1 000 grams-force depending on diameter.

Applications

• Quality control (QC): Verify lubricant application, surface smoothness and uniformity across production batches.
• Lubricant evaluation: Compare lubricant types (mineral oil, paraffin wax) and assess their effect on friction and handling during winding.
• Process optimization: Inform winding machine settings, tension control and winding speeds to reduce breakage and improve coil integrity.
• Supplier / purchaser agreements: Provide objective test methods to specify acceptance criteria and resolve disputes over surface or lubrication issues.

Related Standards

• IEC 60851 series (other parts cover electrical, thermal and insulation properties of winding wires).
• National standards and translations endorsed by CENELEC members (the amendment is to be implemented as a national standard by the dates specified in the foreword).

For implementation, test laboratories should refer to the full EN/IEC text for drawings, tables and procedural tolerances (figures and tables specify detailed dimensions, weights and device arrangements). The amendment emphasizes reproducible measurement, statistical analysis of friction data and the practical value of these tests for consistent winding-wire performance.

B.1 General
Replace this subclause by the following:
This annex provides recommendations to the purchaser and supplier of winding wires with
respect to friction test methods to be used for winding wires. The use of additional methods
can be agreed upon between purchaser and supplier.

B.4 Test C: Second dynamic coefficient of friction test method
Replace the entire clause by the following:
B.4 Test C: Second dynamic coefficient of friction test method (applicable to
enamelled round wires with a nominal conductor diameter from 0,050 mm
up to and including 1,600 mm)
B.4.1 Test equipment
The design of typical test equipment is illustrated in Figure B.3. Figure B.4 contains detailed
drawings of synthetic sapphires and Figure B.5 is a photograph of the load block. The tester
is supplied with a wire guiding system and a take-up which pulls the wire over the test bed at
15 m/min as shown in Figure B.6. The test block is aligned parallel with the test bed and the
test weights are perpendicular to the wire specimen.
As the wire is pulled under the test block (synthetic sapphires), the friction between the wire
surface and the sapphire surface develops a longitudinal force, which is transferred to the
measuring system by a shaft supported by two sets of linear ball bearings in contact with the
measuring system. The force indicated by the measuring system is divided by the load on the
test surface to obtain the dynamic coefficient of friction.
The measuring system in Figure B.3 shows
