What type of testing is typically required for rubber lineman's gloves?

Biannual electrical testing is essential for rubber lineman's gloves because these gloves are designed to insulate against electrical hazards. Over time, even rubber can degrade due to environmental factors, wear and tear, and potential exposure to chemicals. Conducting electrical testing every two years ensures that the gloves maintain their protective qualities and remain safe for linemen working with high voltage lines.

Though daily visual inspections are crucial for identifying any visible damage, they do not assess the gloves' ability to withstand electrical current. Similarly, flexibility testing and mechanical testing, while relevant to overall glove integrity, do not provide the specific electrical safety assessment that is critical for the role of lineman's gloves. Ensuring these gloves can effectively insulate against electricity is paramount, making biannual electrical testing a standard requirement.
