Vodomeri za merjenje hladne pitne vode in vroče vode - 2. del: Preskusne metode (ISO 4064-2:2014)
Standard EN ISO 4064-2 se uporablja za vrednotenje vrste vodomerov in začetno preverjanje vodomerov za hladno pitno vodo in vročo vodo, kot je določeno v standardih ISO 4064-1: 2014|OIML R 49-1: 2013. Certifikat o skladnosti OIML se lahko izda za vodomere, ki jih zajema sistem certificiranja OIML, če se ta del standardov ISO 4064|OIML R 49, ISO 4064-1: 2014|OIML R 49-1: 2013 in ISO 4064-3: 2014|OIML R 49-3: 2013 uporablja v skladu s predpisi sistema. Ta del standarda ISO 4064|OIML R 49 navaja podrobnosti preskusnega programa, načel, opreme in postopkov za vrednotenje vrste in začetnega preverjanja vodomera. Določila tega dela standarda ISO 4064|OIML R 49 se uporabljajo tudi za pomožne naprave, če to zahtevajo nacionalni predpisi. Ta določila vključujejo zahteve za preskušanje celotnega vodomera in za preskušanje merilnega pretvornika (vključno s senzorjem pretoka) ter kalkulatorja vodomera (vključno s prikazovalno napravo) kot ločenih enot.

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 committees responsible for this document are Technical Committee ISO/TC 30, Measurement of fluid
flow in closed conduits, Subcommittee SC 7, Volume methods including water meters and OIML Technical
Subcommittee TC 8/SC 5 Water meters.
This fourth edition of ISO 4064-2 cancels and replaces the third edition (ISO 4064-2:2005), which has
been technically revised. Provisions of the third edition are addressed in ISO 4064-5:2014.
ISO 4064 consists of the following parts, under the general title Water meters for cold potable water and
hot water:
— Part 1: Metrological and technical requirements
— Part 2: Test methods
— Part 3: Test report format
— Part 4: Non-metrological requirements not covered in ISO 4064-1
— Part 5: Installation requirements
This edition of ISO 4064-2 is identical with the corresponding edition of OIML R 49-2, which has been
issued concurrently. OIML R 49-2 was approved for final publication by the International Committee of
Legal Metrology at its 48th meeting in Ho Chi Minh City, Vietnam in October 2013 and will be submitted
to the International Conference on Legal Metrology in 2016 for formal sanction.

System, provided that this part of ISO 4064|OIML R 49, ISO 4064-1:2014|OIML R 49-1:2013 and
ISO 4064-3:2014|OIML R 49-3:2013 are used in accordance with the rules of the System.
This part of ISO 4064|OIML R 49 sets out details of the test programme, principles, equipment and
procedures to be used for the type evaluation, and initial verification of a meter type.
The provisions of this part of ISO 4064|OIML R 49 also apply to ancillary devices, if required by national
regulations.
The provisions include requirements for testing the complete water meter and for testing the
measurement transducer (including the flow or volume sensor) and the calculator (including the
indicating device) of a water meter as separate units.

condition in question. The actual values of the deviating condition, however, shall be measured and
documented as part of the performance test documentation.

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 4064-2 was prepared by Technical Committee ISO/TC 30, Measurement of fluid flow in closed conduits,
Subcommittee SC 7, Volume methods including water meters and OIML Technical Subcommittee TC 8/SC 5
Water meters.
This fourth edition cancels and replaces the third edition of ISO 4064-3 (ISO 4064-3:2005), which has been
technically revised.
This edition of ISO 4064-2 is identical with the corresponding edition of OIML R 49-2, which has been issued
concurrently.
ISO 4064 consists of the following parts, under the general title Water meters intended for the metering of cold
potable water and hot water:
Part 1: Specification of metrological and technical requirements
Part 2: Specification of test methods
Part 3: Specification of test report format
Part 4: Specification of non-metrological requirements not covered in Part 1

1 Scope
This Part of ISO 4064/OIML R 49 is applicable to the type evaluation and initial verification testing of water
meters intended for the metering of cold potable water and hot water as defined in ISO 4064-1/OIML R 49-1
[1]. OIML Certificates of Conformity may be issued for water meters under the scope of the OIML Certificate
System, providing that the first three parts of this Part of ISO 4064/OIML R 49 are used in accordance with the
rules of the System.
This Part of ISO 4064/OIML R 49 sets out details of the test programme, principles, equipment and
procedures to be used for the type evaluation and initial verification testing of a meter type.
The provisions of this Part of ISO 4064/OIML R 49 also apply to ancillary devices, if required by national
regulations.
The provisions include requirements for testing the complete water meter and for testing the measurement
transducer (including the flow or volume sensor) and the calculator (including the indicating device) of a water
meter as separate units.
