ASTM F2675/F2675M – 19

Determining Arc Ratings of Hand Protective Products, Developed and Used for Electrical Arc Flash Protection

This test method determines the gloves protection level against electric arc by measuring the  amount of thermal energy transmitted through the gloves during and after exposure to an electric arc.

The arc thermal performance value, ATPV cal / cm2, is the penetrating energy into the gloves material that results in a 50% probability of sufficient heat transfer through the gloves to cause the onset of a second-degree skin burn.

The higher ATPV value the glove achieves in testing, the higher energy it protects against in the event of an arc exposure. Note that these gloves can reduce the damage in case of exposure to electrical arc,  but do not eliminate the risk of injury.

The gloves’ level of protection can be adversely affected after contact with for example gasoline, diesel fuel, transformer oil, sweat, dirt, grease or other contaminants.
It is the user's responsibility to determine appropriate safety, health and environmental practices and determine the application of regulatory restrictions prior to use.

This standard has no pictogram at the time of writing but the ATPV level is indicated at the inside label of the glove.
