This Standard specifies requirements for water meters for use in cold water systems to measure the volume of cold drinking water or Type A or B recycled water using certain types of meters.

This Standard specifies requirements for water meters for use in cold water systems to measure the volume of cold drinking water or Type A or B recycled water using the following types of meters: (a) Volumetric, not exceeding 63 kL/h.(b) Multi-jet, not exceeding 63 kL/h.(c) Single-jet meters, not exceeding 63 kL/h. (d) Helical vane meters with permanent flow rates not exceeding 250 kL/h. The operating conditions of the meters being—(i) working temperature ranges of 0.3°C to 30°C; and(ii) operating pressures not exceeding 1400 kPa. This Standard is applicable to meters that are self-contained and capable of continuously determining, within the accuracy limits of the class, the volume of cold drinking water that has flowed through them, and that are continuously indicating the volume on a cumulative basis. Means for demonstrating compliance with this Standard is given in Appendix A NOTE: Purchasing guidelines are given in Appendix B.
