AR stands for which term?

Explanation:
AR stands for Arc Rating. This is the protection value assigned to arc-rated PPE and materials, indicating how much heat energy from an arc flash the item can withstand before a significant burn is likely. The rating is given in calories per square centimeter (cal/cm^2) and comes from standardized arc-flash testing. In practice, you choose PPE with an arc rating that is at least as high as the estimated incident energy at the work you’re performing, often selecting higher for a safety margin. The main idea is that arc rating tells you the level of protection against heat exposure from an arc, not anything about current, resistance, or age.
