ASTM D120 – Standard Specification for Rubber Insulating Gloves

Description:

Abstract

This specification covers manufacturing and testing of rubber insulating gloves for protection of workers from electrical shock. Two types of gloves are provided and are designated as Type I, non-resistant to ozone, and Type II, resistant to ozone. Six classes of gloves, differing in electrical characteristics, are provided and are designated as Class 00, Class 0, Class 1, Class 2, Class 3, and Class 4. The following tests shall be performed: ac proof test; ac breakdown test; ac moisture absorption/proof test; dc proof test; dc breakdown test; ozone resistance test; chemical tests; tensile strength; tear resistance test; and puncture resistance test.
