This part of ISO 4064 specifies the test methods and means to be employed in determining the principal characteristics of water meters. This part of ISO 4064 is applicable to cold potable water and hot water concentric and combination meters, which can withstand maximum admissible working pressures (MAP) equal to at least 1 MPa (10 bar) 0,6 MPa (6 bar) for meters W DN 500 mm and a maximum admissible temperature for cold potable water meters of 30 °C and for hot water meters of up to 180 °C, depending on the class. This part of ISO 4064 also applies to water meters based on electrical or electronic principles and to water meters based on mechanical principles incorporating electrical devices, used to meter the actual volume flow of cold potable water and hot potable water. In the case where water meters have a permanent flowrate of less than 160 m3/h, in order to meet individual test laboratory limitations the test schedule may make provisions for modification of the reference conditions, when testing specifically for endurance or for performance under influence quantities. NOTE Attention is drawn to the fact that national legislation may apply in the country
