This standard does not apply to light conveyor belts specified in HG\/T 4601.1. This standard does not apply to the core with a thickness of more than 20mm conveyor belt and fabric layer of rubber or plastic sandwich thickness of more than 0.8mm conveyor belt. This standard does not apply to the delivery of high temperature products over 100 �� heat conveyor belt and the ambient temperature below -40 �� conveyor belt.
