1:1984 and at the test temperature given in Table 7. Table 7 — Application of glow-wire test Part Parts necessary to retain live parts in position Parts not necessary to retain live parts in position (although they may be in contact with live parts) Temperature of glow wire Portable socket-outlets Fixed socket-outlets °C °C 750 ± 10 850 ± 15 650 ± 10 650 ± 10 NOTE 1 If the test specified is required to be made at more than one place on the same specimen, it is essential that care is taken to ensure that any deterioration caused by previous tests does not affect the result of the test to be made.

The oscillating member is moved backwards and forwards through an angle of 45° ± 3° on either side of the 0 vertical, the number of flexings being 10 000 at a rate of 60 –10 per minute. After 5 000 flexings, socket-outlets are turned through 90° ± 5° about the cord entry centreline. NOTE A flexing is one movement through 90°, either backwards or forwards. During the test there shall be no interruption of the current passing through the conductors and no short circuit between them. After the test the sample shall show no damage except that breakage of no more that 10 % of the total number of conductor strands in any core is ignored provided they have not pierced the insulation.
