GB/T 7721-2017 Continuous totalizing automatic weighing instruments(belt weighers)
Abstract
This standard specifies the terminology, product models, requirements, inspection methods and rules, marking, packaging, transportation, and storage of continuous cumulative automatic weighers for belt conveyors (hereinafter referred to as "belt scales"). This standard also provides standardized requirements, test procedures, and forms for evaluating the metrological or technical characteristics of belt scales in a traceable manner. This standard applies to: -- Belt scales that use the principle of gravity to determine and accumulate the mass of bulk materials in a continuous weighing manner. -- Belt scales used with single-speed belt conveyors, variable-speed or multi-speed belt conveyors.
