ASTM D120 Standard Specification for Rubber Insulating Gloves
ASTM D120 福特粘度杯测定粘度标准试验方法

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.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
