Specifies requirements for pin and shackle insulators, in which the insulating material is of porcelain or glass, for outdoor use at a nominal voltage not exceeding 1000 volt a.c. Dimensions, material, and mechanical performance are specified.

This Standard specifies requirements for low voltage pin and shackle insulators in which the insulating material is of porcelain or annealed glass, and which are for use outdoors, at a nominal voltage not greater than 1000 V a.c. and a frequency of not greater than 100 Hz.NOTE: Appendix A lists in formation which should be specified by the purchaser of the insulators.
