The referenced standards projects are being considered for approval and the publication of this notice begins the 45-day public comment period for AWWA and ANSI. An electronic public review copy of the proposed standards can be obtained for review during the comment period by emailing ETS Support. Comments must be submitted in writing to the AWWA contact listed below no later than the last day of the comment period specified herein. Such comments shall be specific to the section(s) of the standard under review and include sufficient detail so as to enable the reader to understand the commenter's position, concerns and suggested alternative language, if appropriate. AWWA Comment Period closed on November 11, 2019. Send comments to: Frank Kurtz 303.347.6221 phone 303.795.7603 fax The review copies will be edited for publication and may also be revised as appropriate based on any comments received during the public comment period. Therefore, these copies are not suitable for continued utilization and intended only for comment purposes. Final publication of the standards may take several months. When they are available, a notice will be published in the official notice section of Journal - American Water Works Association. The standard becomes an effective AWWA standard on the first day of the month following such publication in Journal - American Water Works Association. ANSI/AWWA C701-19 – COLD-WATER METERS – TURBINE TYPE, FOR CUSTOMER SERVICE SCOPE This standard describes the various classes of cold-water turbine meters in sizes ¾ in. (20 mm) 12 through 20 in. (500 mm) for water supply customer service, mainline metering, and custody transfer of water among purveyors, and the materials and workmanship employed in their fabrication. MAJOR REVISIONS Major changes made to the standard in this edition include the following: Guidance on selection of materials in terms of chlorine and chloramine degradation of elastomers has been provided in the foreword (Sec. II.B). Reference to ANSI/AWWA C706 on Direct Reading, Remote Registration Systems for Cold Water Meters has been removed (Sec. 4.3.6). (ANSI/AWWA C706 was withdrawn as an AWWA standard in 2015.) Provisions for meter marking have been moved from Sec. 6.1 to Sec. 4.4. (The content of the requirements is unchanged.) ANSI/AWWA C702-19 – COLD-WATER METERS – COMPOUND TYPE SCOPE This standard describes the various types and classes of cold-water compound-type meters in sizes 2 in. (50 mm) through 8 in. (200 mm), and the materials and workmanship used in their fabrication. Compound meters shall consist of a combination of a turbine-type mainline meter for measuring high rates of flow and a bypass meter of an appropriate size for measuring low rates of flow. MAJOR REVISIONS Major changes made to the standard in this edition include the following: Guidance on selection of materials in terms of chlorine and chloramine degradation of elastomers has been provided in the foreword (Sec. II.A). A requirement for a maximum registration for the bypass meter has been added (Sec. 9 4.2.6.3). Reference to ANSI/AWWA C706 on Direct Reading, Remote Registration Systems for Cold Water Meters has been removed (Sec. 4.3.7). (ANSI/AWWA C706 was withdrawn as an AWWA standard in 2015.) Provisions for meter marking have been moved from Sec. 6.1 to Sec. 4.4. (The content of the requirements is unchanged.) ANSI/AWWA C703-19 – COLD-WATER METERS – FIRE-SERVICE TYPE SCOPE This standard describes the various types and classes of cold-water fire-service–type meters in sizes 3 in. (80 mm) through 10 in. (250 mm), and the materials and workmanship used in their fabrication. MAJOR REVISIONS Major changes made to the standard in this edition include the following: Guidance on selection of materials in terms of chlorine and chloramine degradation of elastomers has been provided in the foreword (Sec. II.A). The accuracy at which the changeover begins and the registration requirements at the changeover flow rates have been modified. Reference to ANSI/AWWA C706 on Direct Reading, Remote Registration Systems for Cold Water Meters has been removed (Sec. 4.3.6). (ANSI/AWWA C706 was withdrawn as an AWWA standard in 2015.) Provisions for meter marking have been moved from Sec. 6.1 to Sec. 4.4. (The content of the requirements is unchanged.) ANSI/AWWA C704-19 – PROPELLER-TYPE FOR WATERWORKS APPLICATIONS SCOPE This standard describes the various types and classes of propeller meters in sizes 2 in. (50 mm) through 72 in. (1,800 mm) for waterworks applications. These meters register by recording the revolutions of a propeller set in motion by the force of flowing water striking the blades. MAJOR REVISIONS Major changes made to the standard in this edition include the following: Guidance on selection of materials in terms of chlorine and chloramine degradation of elastomers has been provided in the foreword (Sec. II.B). Provisions for meter marking have been moved from Sec. 6.1 to Sec. 4.4. (The content of the requirements is unchanged.) ANSI/AWWA C708-19 – COLD-WATER METERS – MULTIJET TYPE SCOPE This standard describes cold-water multijet meters in sizes 5/8 in. (15 mm) through 2 in. (50 mm) for water utilities’ customer service and the materials and workmanship employed in their fabrication. These meters register by recording the revolutions of a rotor set in motion by the force of flowing water striking the blades. MAJOR REVISIONS Major changes made to the standard in this edition include the following: Guidance on selection of materials in terms of chlorine and chloramine degradation of elastomers has been provided in the foreword (Sec. II.B). Reference to ANSI/AWWA C706 on Direct Reading, Remote Registration Systems for Cold Water Meters has been removed (Sec. 4.3.6.4). (ANSI/AWWA C706 was withdrawn as an AWWA standard in 2015.) Provisions for meter marking have been moved from Sect. 6.1 to Sec. 4.4. (The content of the requirements is unchanged.) ANSI/AWWA C712-19 – COLD-WATER METERS – SINGLEJET TYPE SCOPE This standard describes the various types and classes of cold-water singlejet meters in sizes 5/8 in. (15 mm) through 6 in. (150 mm) for water utilities’ customer service and the materials and workmanship employed in their fabrication. These meters register by recording the revolutions of a rotor powered by the force of flowing water striking its blades. MAJOR REVISIONS Major changes made to the standard in this edition include the following: Guidance on selection of materials in terms of chlorine and chloramine degradation of elastomers has been provided in the foreword (Sec. II.B). Reference to ANSI/AWWA C706 on Direct Reading, Remote Registration Systems for Cold Water Meters has been removed (Sec. 4.3.7). (ANSI/AWWA C706 was withdrawn as an AWWA standard in 2015.) Provisions for meter marking have been moved from Sect. 6.1 to Sec. 4.4. (The content of the requirements is unchanged.) ANSI/AWWA C713-19 – COLD-WATER METERS – FLUIDIC-OSCILLATOR TYPE SCOPE This standard describes cold-water fluidic-oscillator meters with brass main cases in sizes ½ in. (13 mm) through 2 in. (50 mm), and the materials and workmanship employed in their fabrication. The basis for volume measurement is a transducer element that senses and utilizes fluidic oscillation rather than a moving measurement element, as required in traditional cold-water volumetric meters. MAJOR REVISIONS Major changes made to the standard in this edition include the following: Guidance on selection of materials in terms of chlorine and chloramine degradation of elastomers has been provided in the foreword (Sec. II.B). Reference to ANSI/AWWA C706 on Direct Reading, Remote Registration Systems for Cold Water Meters has been removed (Sec. III.A). (ANSI/AWWA C706 was withdrawn as an AWWA standard in 2015.) Provisions for meter marking have been moved from Sec. 6.1 to Sec. 4.4. (The content of the requirements is unchanged.)
