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.

Rubber Insulating Testing Schedule
| Type of equipment | When to test |
Rubber insulating blankets............... Before first issue and every 12 months thereafter.*
Rubber insulating gloves.................. Before first issue and every 6 months thereafter.*
Rubber insulating sleeves................. Before first issue and every 12 months thereafter.*
-----------------------------------------------------------------------*If the insulating equipment has been electrically tested but not issued for service, it may not be placed into service unless it has been electrically tested within the previous 12 months.
