BS 5421-2 also defines a method intended to determine the amount of staining caused to adjacent textile materials and the amount of discolouration of a polyurethane thread when it is washed in water containing dissolved copper salts This test has only a comparative value and may not indicate the exact performance of a thread in service because of the wide variation of copper contents of domestic water supplies

Trapezoidal thread serves the purpose of producing linear motion when rotated

The object of these supplementary requirements is to establish the characteristics of semiconductor fuse-links in such a way that they can be replaced by other fuse-links having the same characteristics

It does not apply to equipment intended to be connected only to private low-voltage systems interfacing with the public supply only at the medium- or high-voltage level
