Electricity metering equipment - Dependability - Part 32-1: Durability - Testing of the stability of metrological characteristics by applying elevated temperature

IEC 62059-32-1:2011 specifies a method for testing the stability of metrological characteristics of electricity meters, by operating a test specimen at the upper limit of the specified operating range of temperature, voltage and current for an extended period.

La CEI 62059-32-1:2011 spécifie une méthode pour les essais de stabilité des caractéristiques métrologiques des compteurs d'électricité, en faisant fonctionner un exemplaire d'essai à la limite supérieure de la température, de la tension et du courant dans le domaine de fonctionnement spécifié, pendant une durée prolongée.

Oprema za merjenje električne energije - Zagotovljivost - 32-1. del: Trajnost - Preskušanje stabilnosti meteoroloških karakteristik s povišano temperaturo (IEC 62059-32-1:2011)

Stabilnost meteoroloških karakteristik je pomemben vidik trajnosti. Ta del standarda IEC 62059 določa metodo za preskušanje stabilnosti meteoroloških karakteristik števcev električne energije, tako da preskušanec daljše obdobje deluje pri zgornji meji območja delovanja, kar zadeva temperaturo, napetost in tok. Funkcijska zmogljivost, razen točnosti merjenja električne energije, ne spada v področje uporabe tega standarda. Upoštevati je treba, da zaključki glede dolžine obdobja, v katerem se ohrani stabilnost meteoroloških karakteristik, kadar števec deluje v običajnih pogojih, na podlagi rezultatov tega preskusa niso mogoči. Ta mednarodni standard se uporablja za vse vrste števcev električne energije, ki spadajo v področje uporabe IEC TC 13.

The standard covers the Essential Requirement 5, Durability, Annex I of the Directive
2004/22/EC of the European Parliament and of the council of 31 March 2004 on measuring
instruments (MID):
“A measuring instrument shall be designed to maintain an adequate stability of its metrological
characteristics over a period of time estimated by the manufacturer, provided that it is properly
installed, maintained and used according to the manufacturer's instruction when in the
environmental conditions for which it is intended.”
Compliance with this standard provides one means of conformity with the specified essential
requirements of the Directives concerned.
WARNING - Other requirements and other EU Directives may be applicable to the products
falling within the scope of this standard.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
