SIST ISO 4064-3:2006

Measurement of water flow in fully charged closed conduits -- Meters for cold potable water and hot water -- Part 3: Test methods and equipment

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.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 4064-3 was prepared by Technical Committee ISO/TC 30, Measurement of fluid flow in closed conduits,
Subcommittee SC 7, Volume methods including water meters.
This third edition cancels and replaces the second edition (ISO 4064-3:1999), which has been technically
revised, as well as cancelling and replacing ISO 7858-3:1992.
ISO 4064 consists of the following parts, under the general title Measurement of water flow in fully charged
closed conduits — Meters for cold potable water and hot water:
⎯ Part 1: Specifications
⎯ Part 2: Installation requirements
⎯ Part 3: Test methods and equipment

1 Scope
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 m /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 of use, which will take
precedence over the provisions of this part of ISO 4064.
