Testing
Rubber insulating equipment is tested for maximum intervals between electrical testing according the schedule below.
Rubber Insulating Equipment and When to Test
- Rubber insulating line hose - Upon indication that insulating value is suspect and after repair.
- Rubber insulating covers - Upon indication that insulating value is suspect and after repair.
- Rubber insulating blankets - Before first issue and every 12 months thereafter1 upon indication that insulating value is suspect; and after repair.
- Rubber insulating gloves - Before first issue and every 6 months thereafter1 upon indication that insulating value is suspect; after repair; and after use without protectors.
- Rubber insulating sleeves - Before first issue and every 12 months thereafter1 upon indication that insulating value is suspect; and after repair.
Footnote (1): 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.
The test method used must reliably indicate whether the insulating equipment can withstand the voltages involved. Repaired insulating equipment must be retested before it may be used by employees.

Certification
The employer must certify that equipment has been tested in accordance with the requirements of the standard, and the certification must identify the equipment that passed the test and the date it was tested.
Marking equipment and entering the results of the tests and the testing dates onto logs are two acceptable ways to meet this requirement.
