1 Scope
This standard specifies the technical requirements, test methods, test rules, mark, packaging and storage of the belt conveyer (hereafter referred to as “conveyer”).
This standard is applicable to the transportation of different kinds of massive, granular bulk materials as well as conveyers.
For conveyers with special requirements and patterns, the universal part shall also be referred to.
