Periodic Testing Of 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.
Electrical Insulation Tests For Gloves Table 1

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 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 of 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 mix the periodic inspection with the inspection before each use: this is strongly recommended and consists of a visual inspection after air inflation. It is also important to store the gloves in their UV resistant plastic bag and keep gloves away from light, heat and ozone. Ideally, the user should use our Pneumatic Tester, and the plastic box for better transportation and stock.
4 - Special properties
Gloves that pass the special properties (acid, oïl, ozone, very low temperature) are not resistant to chemicals. This is a to guarantee electrical protection in case of accidental contacts. After completing the electrical job, it is recommended to replace the contaminated gloves. Most of our gloves are RC (maximum), 00 and 0 are AZC (no resistance to oïl); Class 0 RC is available on demand.
We offer the periodic dielectric inspection service.
- On receipt of your order onto 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 electrical testing, at the correct voltage for their class, which is carried out using various test equipment; finally they are inflated and visually inspected again, then stamped and packed for returned
- Documentation accompanies the gloves and sleeves through all stages of testing and any failures are recorded and then destroyed. If the customer wishes, failures can be replaced with new items from our stocks.
