EN 60903 - Live working - Electrical insulating gloves
EN 60903 - Live working - Electrical insulating gloves
EN 60903:2003 - Gloves and mitts of insulating material for live working, corrected 2004 and 2006.
This European Standard specifies the requirements and test methods for gloves and wiring gloves intended for use by workers exposed to high-tension electrical voltage. This standard and does not make reference to other glove standards, such as EN 420 (general requirements), EN 388 (mechanical risks), or EN 374 (chemical risks).
Gloves that are manufactured and certified according to EN standard 60903 are the only gloves that should be used when there is a risk of electrical shock. To help determine which gloves provide the best protection, it is important to know gloves’ capacities relative to different voltage levels.
To limit the effects of wear and tear (e.g., contact with sharp cables), specially designed protective gloves can and should be worn over electrical insulating gloves.

Optional:
| Category optional | Additional requirements |
| A | Acid resistance |
| H | Oil resistance |
| Z | Ozone resistance |
| M | Resistance against high mechanical strain |
| R | Resistance against acid, oil, ozone, and high mechanical strain |
| C | Resistance against extreme cold |
Insulating protective gloves require inspections every 6 months and should be subjected to the following:
Classes 00 and 0 – examination to detect air leaks and visual inspection
Classes 1 to 4 – examination to detect air leaks, visual inspection, and electrical test
Protective gloves should be individually packaged. This packaging must be durable enough to protect the gloves against damages that may occur during shipment (e.g., prolonged exposure to direct sunlight, excessive moisture, temperatures above and below room temperature). Furthermore, the protective gloves’ safety markings must be displayed prominently on the packaging.
