DIN Standards Committee Technical Fundamentals

Overview

The European Standard is a new edition. It is applicable to the type evaluation and initial verification testing of water meters for cold potable water and hot water as defined in DIN EN ISO 4064-1. OIML Certificates of Conformity can be issued for water meters under the scope of the OIML Certificate System, provided that the first three parts of DIN EN ISO 4064 are used in accordance with the rules of the system. This European Standard sets out details of the test programme, principles, equipment and procedures to be used for the type evaluation, and initial verification of a meter type. The provisions of this part document also apply to ancillary devices, if required by national regulations. The provisions include requirements for testing the complete water meter and for testing the measurement transducer (including the flow or volume sensor) and the calculator (including the indicating device) of a water meter as separate units. The responsible committees are CEN/TC 92 "Water meters" (secretariat SNV, Switzerland) and, at the national level, DIN-DVGW Joint Working committee NA 119-07-08 AA "Wassermessung" ("Water metering") at DIN Standards Committee Water Practice (NAW).
