What kind of voltages do rubber gloves need to be tested against?

Rubber gloves used by linemen must be tested against test voltages to ensure their effectiveness in providing electrical insulation. Test voltages are higher than the operating voltages that the gloves will typically encounter during normal use. This is crucial since testing against a higher voltage allows for the identification of any potential defects or weaknesses in the gloves, ensuring they can handle extreme conditions and accidental contact with high-voltage sources. This thorough testing is part of safety protocols and standards aimed at protecting workers from electrical hazards.

Options involving operating voltages, impulse voltages, or industrial voltages do not capture the requirement for testing rubber gloves as they relate to the actual conditions the gloves may face in the field, rather than testing for safety and suitability under more strenuous conditions.
