GB/T 7721-2007 Continuous totalizing automatic weighing instruments(electronic belt weighers)
Abstract
This standard specifies the terms and definitions, product models, metrological performance requirements, general technical requirements, requirements for electronic belt scales, test methods, inspection rules, and marking, packaging, transportation, and storage of continuous cumulative automatic weighing devices for belt conveyors (hereinafter referred to as "electronic belt scales"). It also stipulates the test procedures for type evaluation of electronic belt scales (see Appendix A) and the format of the type evaluation report (see Appendix B). This standard applies to electronic belt scales that use the principle of gravity to determine and accumulate the mass of bulk materials in a continuous weighing manner, and also applies to electronic belt scales used with single-speed belt conveyors or variable-speed belt conveyors.
