This document specifies the maximum electrical resistance of the following: —     antistatic endless V-ribbed belts; —     joined V-belts; —     single V-belts, including wide section belts and hexagonal belts. This document also specifies the corresponding production control and individual proof methods of measurements. This document applies to new belts intended to be used in an explosive atmosphere or in situations where there is a fire risk. The test is intended to ensure that the belt is sufficiently conductive to dissipate charges of electricity which can form on it in service.
