5.5 Adherence test
Replace the existing subclause by the following:
5.5 Adherence test
A straight piece of wire of about 300 mm length shall be elongated in accordance with
Clause 3 to the percentage specified in the relevant standard.
5.5.1 Enamelled rectangular wire
Before elongation, the coating shall be cut circumferentially through to the conductor at a
point approximately in the centre of the measured length. After elongation, the specimen shall
be examined for loss of adhesion.
One specimen shall be tested. If loss of adhesion is observed, as determined by longitudinal
measurement from the cut, it shall be reported. If so, the length of loss of adhesion shall be
measured in one direction from the cut. The maximum value observed shall be reported after
examining all sides of the specimen, under a magnification of six to ten times.
5.5.2 Impregnated fibre covered round and rectangular wire
Before elongation, the insulation shall be cut circumferentially at two places 100 mm apart in
the centre of the wire specimen through to the conductor. After elongation, the specimen shall
be examined for loss of adhesion under a magnification of six to ten times.
One specimen shall be tested. If loss of adhesion is observed according to the relevant
specification, it shall be reported.
