GB/T 28013-2011 regulates the discontinuous cumulative automatic weighing device. The standard specifies the classification, structure and working principle of this type of weighing device, specifies its weighing range, cumulative error and other key performance indicators in detail, and puts forward requirements for the Stability and durability of the weighing device. At the same time, develop comprehensive inspection and testing methods, standardize product labels, Encasement and other content. This standard provides a unified standard for the production, testing, sales and use of discontinuous cumulative automatic weighing devices to ensure their accurate cumulative weighing in industrial production and other fields, and ensure the accuracy and Reliability of Measurement.
