BS EN ISO 22721:2007 specifies requirements for rubber- or plastics-covered conveyor belting of textile construction for underground mining on flat or troughed idlers. It is not applicable to light conveyor belts as described in ISO 21183-1. BS EN ISO 22721 does not include requirements for plastics covers. These will need to be agreed upon by the manufacturer and purchaser, taking into account the type of plastics to be used. Related items that are not requirements of this Standard, but which it is recommended be agreed upon by the manufacturer and purchaser, and details recommended to be supplied by the purchaser of belting with an enquiry are also given. The ability of a belt to run straight cannot be assessed until the belt is installed. Requirements for this are, therefore, outside the scope of this Standard; nevertheless, recommendations for lateral drift are given.
