Date: 10 22, 2026   
Recently, upon review and recommendation by the State Administration for Market Regulation, the International Organization of Legal Metrology (OIML) has approved Jiangsu Institute of Metrology as a designated laboratory under the OIML Certification System (OIML-CS). The laboratory will conduct international type evaluation tests for electricity meters and continuous totalizing automatic weighing instruments (belt weighers).

The OIML-CS is an international mutual recognition system for issuing, registering and using OIML type evaluation certificates. Its designated laboratories carry out tests and issue globally recognized type evaluation reports. The system enables "one test, one certificate, global recognition" for measuring instruments, which is of great significance for boosting international trade, lowering trade barriers, enhancing mutual trust among countries and advancing global economic integration.

According to statistics from the General Administration of Customs, China exported approximately 60 million electricity meters in 2025, with an export value of about 10.4 billion yuan. Belt weighers are widely applied in bulk commodity trade sectors including ports, mines, metallurgy and building materials, serving as an essential guarantee for trade settlement.

The laboratory will deliver global one-stop services covering testing and evaluation of metrological instruments and equipment. It helps build a complete metrology service chain of "product development – local type evaluation – international mutual recognition", it will provide solid technical support for the research and internationalization of the enterprises related to metrological instrumentation and equipment.
