International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the Internatio
31、nal Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different

36、NATIONAL STANDARD ISO 4064-4:2014(E)Water meters for cold potable water and hot water Part 4: Non-metrological requirements not covered in ISO 4064-11 ScopeThis part of ISO 4064 applies to water meters used to meter the volume of cold potable water and hot water flowing through a fully charged, clos
37、ed conduit. These water meters incorporate devices which indicate the integrated volume.This part of ISO 4064 specifies technical characteristics and pressure loss requirements for meters for cold potable water and hot water. It applies to water meters which can withstand:a) a maximum admissible pre
38、ssure (MAP) equal to at least 1 MPa1)0,6 MPa for meters for use with pipe nominal diameters (DNs) 500 mm;b) a maximum admissible temperature (MAT) for cold potable water meters of 30 C;c) a MAT for hot water meters of up to 180 C, depending on class.In addition to meters based on mechanical principl
39、es, 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 electronic devices, used to meter the volume flow of hot water and cold potable water. It also applies to electronic ancillary devices
40、. As a rule ancillary devices are optional. However, national or international regulations may make some ancillary devices mandatory in relation to the utilization of the water meter.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and a
