JJF 1025‑2025, Technical Requirements for Modification of Mechanical Scales, is an important revision of the technical specification. It adds new technical requirements consistent with current engineering practices, tightens the selection requirements for weighing sensors and indicators, and introduces a compatibility verification checklist. Meanwhile, modified electromechanical combined scales are brought under type‑approval administration, and the mandatory binding force of technical clauses on metrological safety and measuring‑instrument marking is strengthened.
The comprehensive upgrade of these technical requirements marks that China has gradually built a regulatory system for mechanical‑scale modification adapted to the rule‑of‑law governance requirements of the new era. The implementation of this specification not only provides a technical basis for the modification of mechanical lever scales applied in special scenarios, but also offers institutional support for ensuring the product quality of electromechanical combined scales, safeguarding fairness in trade settlement and protecting consumers’ legitimate rights and interests.
