Periodic Testing Of Electrician's Safety Gloves Classes 00, 0, 1, 2, 3 and 4
Improper use of rubber insulating gloves can be a matter of life and death. Get them retested regularly to make sure that they are still electrically safe. Treat your rubber gloves well and they can last a long time

1 - Expiration date
Insulating rubber gloves have no expiry date and may be used as long as they comply with the periodic inspection.
2 - The periodic inspection
Class 00 and Class 0
For class 00 and class 0 gloves, a check for air leaks and a visual inspection may be considered adequate. However, a routine dielectric test may be performed at the owner's request.
Class 1, 2 , 3 and 4
No gloves of class 1, 2, 3, and 4, not even those held in storage, should be used unless they have been tested within a maximum period of six months.
3 - Field inspection and stock
Do not confuse the periodic inspection with the inspection before each use. Together with the periodic inspection, it is strongly recommended that a visual inspection of the gloves is carried out before each use. It is important to store the gloves in their UV-Resistant polythene bag and keep the gloves away from light, heat, and ozone. Ideally, the user should use our pneumatic tester to inflate the gloves for a good visual inspection and keep the gloves in our polypropylene store box for both transportation and storage.
4 - Special properties
Gloves that pass the special properties (acid, oïl, ozone, very low temperature) are not resistant to chemicals. The test is to guarantee electrical protection in case of accidental contacts. After completing the electrical work, it is recommended to replace the contaminated gloves. Most of our gloves are RC (maximum), 00, and 0 are AZC (no resistance to oil); Class 0 RC is available on demand.
We offer the periodic dielectric inspection service.
- On receipt of your gloves to our premises, the gloves and sleeves are documented and then washed and dried.
- They are then visually inspected by our technicians, using inflation equipment.
- The next stage is the electrical testing. Test equipment is used and tests are carried out according to the correct voltage for the class of glove. After the electrical testing has been completed they are again inflated and visually inspected. The gloves are then stamped and packed for return.
- Documentation accompanies the gloves and sleeves through all stages of testing and any failures are recorded. Any glove that fails will be destroyed. If the customer wishes, failures can be replaced with new items from our stocks.
