Specifies requirements for volumetric chamber-type meters and turbine-type meters used for measuring the volume of cold potable water in residential, commercial and industrial applications and which have nominal flow rates not greater than 40 kL/h and not greater than 250 kL/h, respectively. It is applicable to meters which are self-contained and capable of continuously determining, within the accuracy limits set out in the Standard, the volume of water which has flowed through them and are continuously indicating the volume on a cumulative basis. Installation guidelines are given in Appendix A. Test methods and equipment guidelines are given in Appendix B.
