Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International 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 types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2, www.iso.org/directives.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any
patent rights identified during the development of the document will be in the Introduction and/or on
the ISO list of patent declarations received, www.iso.org/patents.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
The committee responsible for this document is ISO/TC 30, Measurement of fluid flow in closed conduits,
Subcommittee SC 7, Volume methods including water meters.
ISO 4064 consists of the following parts, under the general title Water meters for cold potable water and
hot water:

INTERNATIONAL STANDARD ISO 4064-4:2014(E)
Water meters for cold potable water and hot water —
Part 4:
Non-metrological requirements not covered in ISO 4064-1
1 Scope
This 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, closed 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:
1)
a) a maximum admissible pressure (MAP) equal to at least 1 MPa [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 principles, 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. 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 references

Meter size is characterized either by the thread size of the end connections or by the nominal size of the
flange. For each meter size, there is a corresponding fixed set of overall dimensions. The dimensions of
the meter, as illustrated in Figure 1, shall be in accordance with Table 1.
