What is the duration of the proof test for rubber gloves?

The proof test for rubber gloves is typically conducted for a duration of 3 minutes. This duration is essential to ensure that the gloves effectively resist electrical current, confirming their integrity and safety for use in electrical work. During this test, the gloves are subjected to a specified voltage, and maintaining the duration at 3 minutes allows sufficient time for any potential leaks or defects to manifest, ensuring that the gloves provide adequate protection. The testing protocol prioritizes safety standards, and a shorter duration would not provide enough time to accurately assess the gloves' quality and reliability, while a longer duration might not yield additional benefits and could potentially compromise the gloves' material integrity.
