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
