Summary
This Standard specifies the electronic spiral scales (also known as spiral reamer scale, screw feeder weigher, hereinafter referred to as "spiral scale") terms, product model, requirements, test methods and inspection rules, marking, packaging, transportation and storage. This Standard is also measured characteristic or technical characteristics traceable way to test spiral scale to provide standardized requirements and test procedures. This Standard applies to the use of gravity theory, continuous weighing mode, single-speed, multi-speed or variable speed screw conveyor for use with bulk materials and to determine the cumulative flow and quality of screw conveyor type continuous totalizing automatic weighing instruments (electronic spiral scales).
