Basic Information
Scope
Scope: This document specifies the safety requirements and test methods for drinking water cold water meters and their connecting parts. This document applies to water meters with a nominal diameter of 15 mm to 40 mm, a maximum allowable pressure (MAP) of ≤1.6 MPa, and a maximum allowable temperature (MAT) of 50℃, and of different accuracy grades. This document applies to water meters whose pressure-bearing parts, such as the meter case, are made of metal or engineering plastics. Main technical content: On the basis of the Ministry of Housing and Urban-Rural Development's industry standard CJ 266-2008 "Safety Rules for Drinking Water Cold Water Meters", and in combination with the current actual situations of new materials and new processes in the industry and future development trends, this document further refines and supplements the safety and hygiene requirements for drinking water cold water meters, providing a technical basis for the design, manufacture, and procurement of pressure-bearing parts such as the meter case.
