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.  

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

According to IEC 60903 : 2014 : « It is recommended to test gloves every 6 months when in use and every 12 months if in stock. The date of manufacture is the date of the original test. The tests consisted of air inflation to check the air flow, a visual inspection Under pressure, and the a dielectric test.»

Local regulations may be considered for class 00 and 0 gloves (Air inflate + Visual Inspection Only).  

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 contaminanted 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. 

  1. On receipt of your order onto our premises , the gloves and sleeves are documented and then washed and dried.
  2. They are then visually inspected by our technicians, using inflation equipment.
  3. 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
  4. 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.
