GB/T 31890-2015 regulates electronic spiral scales. The standard specifies the classification of electronic spiral scales and elaborates on their structural design, including spiral conveyor components, weighing Sensors and other structural requirements. It specifies key performance indicators such as weighing range, Measurement accuracy, accumulated error, etc., and proposes guidelines for equipment Stability and operation Reliability. At the same time, it standardizes product identification, installation and commissioning procedures and inspection methods. This standard provides unified specifications for the production, installation and mass inspection of electronic spiral scales, ensuring their accurate operation in the weighing process of material transportation, and helping related industries to produce efficiently and orderly.
