The arc rating indicates the garment's resistance to which type of energy in arc flash scenarios?

Explanation:
Arc rating is a measure of how much heat from an arc flash the garment can withstand. It quantifies the thermal energy, known as incident energy, that the fabric can protect against for the test duration. This energy is expressed in cal/cm^2 and represents the heat flux reaching the skin through the clothing during an arc event. The rating helps you choose PPE that can handle the expected heat exposure in your environment. It is not a measure of electrical energy or mechanical damage, even though the arc originates from electricity.
