[China Instrument Network Instrument Industry] Recently, Zhejiang Institute of Metrology completed the 1,000-hour limit life test under the condition of the first volumetric water meter overload condition in China, and provided technical support for the quality improvement of “Zhejiang-made†products.
The 1000-hour life test is the ultimate challenge to product performance, and it also imposes higher requirements on the technical organization's capabilities and equipment reliability. The ultimate life test is an important method for verifying the influence of product structure, materials, and processes on product quality. The test requires high requirements and takes a long time. At present, the national standard for water meters and the internationally-recommended indicators are 100 hours, and the indicator for the "Zhejiang-made" group standard in "volumetric water meters" is 300 hours.
In October 2017, Zhejiang Institute of Metrology carried out certification testing for “Zhejiang-made†products based on the “Zhejiang Manufacturing†group standard T/ZZB 0224-2017 “Volumetric Water Meter†to help the company's European Belgian factory obtain “Zhejiang Manufacturing†international certification. The first overseas factory certification issued by the Alliance. The 1,000-hour limit life test carried out this time is based on this certification test.
Through experiments, we have verified the excellent quality of "Zhejiang Made" products, and provided enterprises with more detailed and basic data for further analysis of product structure, materials, and processes.
