标准范围

ISO 4064-3:2005规定了用于确定水表主要特性的试验方法和方法。ISO 4064-3:2005适用于冷水饮用水和热水同心式和组合式水表，对于大于DN 500的水表，其可承受至少1 MPa（10 bar）（0.6 MPa（6 bar）的最大容许工作压力，对于冷水饮用水表，其最高容许温度为30°C，对于热水表，其最高容许温度为180°C，具体取决于等级。ISO 4064-3:2005还适用于基于电气或电子原理的水表，以及基于包含电气装置的机械原理的水表，用于测量饮用冷水和热水的实际体积流量。

ISO 4064-3:2005 specifies the test methods and means to be employed in determining the principal characteristics of water meters.ISO 4064-3:2005 is applicable to cold potable water and hot water concentric and combination meters, which can withstand maximum admissible working pressures equal to at least 1 MPa (10 bar) (0,6 MPa (6 bar) for meters greater than DN 500 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.ISO 4064-3:2005 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 water.
