GB 14249-2026 Safety requirements for electronic weighing instrument
Basic Information
Scope
This document specifies the technical requirements for the safety of electronic weighing instruments in non-automatic weighing instruments and various types of automatic weighing instruments, including protection against electric shock, mechanical hazards, flame spread prevention, temperature limits and heat resistance, electromagnetic interference resistance, component protection using interlocking devices, and marking and documentation. It also describes the corresponding test methods. This document applies to weighing instruments that use weighing sensors as force-to-electricity conversion components, electronic weighing meters for weight indication, and various types of electrical control boxes for weighing or automatic control functions of the weighed loads, with electrical safety implemented in Class I and Class II safety modes. This document does not apply to weighing instruments used in explosive environments and high-temperature (temperature ≥ 70°C) environments.
