Scope

Scope: This document specifies the technical requirements, test methods, and judgment rules for the deceptive use characteristics of electronic pricing scales. This document is applicable to electronic pricing scale manufacturers for regulating their production and business operations, and can also be used by metrological administrative supervisors, users of electronic pricing scales, and consumers to identify and determine whether electronic pricing scales have deceptive use characteristics. Main technical content: This standard consists of six parts: 1. Scope; 2. Normative reference documents; 3. Terms and definitions; 4. Technical requirements; 5. Test methods; 6. Judgment rules. The main content can be summarized as "2231", namely "two key definitions", "two important correlations", "three typical features", and "one important test method". Two key definitions: (1) Deceptive use – The process in which an operator intentionally adjusts the weighing results or the total price of goods to deceive consumers, thereby undermining the accuracy of electronic pricing scales. (2) Deceptive use characteristics – The hardware and software features of electronic pricing scales that make it easier for operators to engage in deceptive use. Two important correlations: (1) The correlation between deceptive use and cheating activities; (2) The correlation between deceptive use characteristics and cheating characteristics. Three typical deceptive use features: (1) Software password method. The mode of deceptive use through entering a password, which allows the weighing results to be adjusted according to a preset method. After powering off and restarting or pressing a specific key to exit, the normal weighing mode is restored, and the weighing results can no longer be adjusted. (2) Hardware circuit modification. By modifying the hardware circuit of the electronic pricing scale, the weighing results can be adjusted according to a preset method. By mo
