标准范围

ISO 4064-1:2005规定了饮用冷水和热水表的术语、技术特性、计量特性和压力损失要求。它适用于能够承受至少1 MPa（对于管道公称直径为DN至少500 mm的水表，可承受0.6 MPa）的最大容许工作压力（MAP）和最大容许温度MAT的水表，对于30℃的冷水饮用水表和最高180℃的热水表，具体取决于等级。ISO 4064-1:2005还适用于基于电气或电子原理的水表，以及基于包含电子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。它也适用于电子辅助设备。一般来说，辅助设备是可选的。ISO 4064-1:2005的规范适用于水表，与技术无关，定义为集成测量仪器，持续测定流经水表的水量。

ISO 4064-1:2005 specifies terminology, technical characteristics, metrological characteristics and pressure loss requirements for cold potable water and hot water meters. It applies to water meters that can withstand maximum admissible working pressures (MAP) at least 1 MPa (0,6 MPa for meters for use with pipe nominal diameters, DN at least 500 mm) and a maximum admissible temperature, MAT, for cold potable water meters of 30 oC and for hot water meters up to 180 oC, depending on class.ISO 4064-1:2005 also applies to water meters, based on electrical or electronic principles and to water meters based on mechanical principles incorporating electronic devices, used to meter the actual volume flow of cold potable water and hot water. It also applies to electronic ancillary devices. Generally ancillary devices are optional.The specifications of ISO 4064-1:2005 apply to water meters, irrespective of technology, defined as integrating measuring instruments continuously determining the volume of water flowing through them.
