Water meters for cold potable water and hot water - Part 2: Test methods (ISO 4064-2:2014)

ISO 4064-2:2014|OIML R 49-2:2013 is applicable to the type evaluation and initial verification testing of water meters for cold potable water and hot water as defined in ISO 4064‑1:2014|OIML R 49‑1:2013. OIML Certificates of Conformity can be issued for water meters under the scope of the OIML Certificate System, provided that ISO 4064-2:2014|OIML R 49-2:2013, 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.
ISO 4064-2:2014|OIML R 49-2:2013 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 ISO 4064-2:2014|OIML R 49-2:2013 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.

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.

Annex ZA
(informative)
Relationship between this European Standard and the essential
requirements of Directive 2014/32/EU aimed to be covered
This European Standard has been prepared under a Commission’s standardization request Mandate to
CEN and CENELEC for standardisation in the field of measuring instruments “M/374 EN” to provide one
voluntary means of conforming to essential requirements of Directive 2014/32/EC EU of the European
Parliament and the Council of 26 February 2014 on measuring instruments (Text with EEA relevance).
Once this standard is cited in the Official Journal of the European Union under that Directive
2014/32/EU, compliance with the normative clauses of this standard given in Table ZA.1 confers,
within the limits of the scope of this standard, a presumption of conformity with the corresponding
essential requirements of that Directive 2014/32/EU, and associated EFTA regulations.
Introduction:
The column “Comment” the term "Addressed" indicates the compliance between EN ISO 4064-2:2014
and the relevant requirement in Directive 2014/32/EU. The term "Not (fully) addressed" indicates that
compliance may not (fully) be realised, whilst "Addressed" may also be qualified in other ways. In the
case the requirement is "Not fully addressed", a short statement may explain what is covered. The
indication “Not applicable” means that the requirement in Annex I of Directive 2014/32/EU is not
relevant for Water Meters
The original Directive 2004/22/EU had been amended by Directive 137/2009/EC. These have been
fully replaced by Directive 2014/32/EU. This latest directive has already been amended by Directive
2015/13/EU.
The numbering in the first column will reflects the structure of the new Directive 2014/32/EU.
For purpose of cross-reference the second column indicates the structure of the original Directive
2004/22/EU.
