Electricity metering - Payment systems - Part 31: Particular requirements - Static payment meters for active energy (classes 1 and 2)

IEC 62055-31:2005 applies to newly manufactured, static watt-hour payment meters of accuracy classes 1 and 2 for direct connection, for the measurement of alternating current electrical energy consumption of a frequency in the range 45 Hz to 65 Hz that include a load switch for the purpose of interruption or restoration of the electricity supply to the load in accordance with the current value of the available credit maintained in the payment meter. It does not apply to static watt-hour payment meters where the voltage across the connection terminals exceeds 600 V (line-to-line voltage for meters for polyphase systems). It applies to payment meters for indoor application only, where the payment meter shall be mounted as for normal service Functional requirements that apply to payment meters are also defined and include informative basic functional requirements and tests for the prepayment mode of operation in Annex A. This bilingual version (2013-05) corresponds to the monolingual English version, published in 2005-09.

Equipements de comptage de l'électricité - Systèmes à paiement - Partie 31: Exigences particulières - Compteurs statiques à paiement d'énergie active (classes 1 et 2)

La CEI 62055-31:2005 s'applique à des compteurs à paiement statiques de wattheures nouvellement fabriqués de classe 1 et 2 pour raccordement direct, pour la mesure de la consommation d'énergie électrique en courant alternatif d'une fréquence allant de 45 Hz à 65 Hz incluant un commutateur de charge ayant pour but d'interrompre ou de rétablir la fourniture d'électricité à la charge en fonction de la valeur courante du crédit disponible maintenu dans le compteur à paiement. Elle ne s'applique pas aux compteurs à paiement dont la tension entre bornes de raccordement dépasse 600 V (tension entre phases pour les compteurs de systèmes polyphasés). Elle s'applique aux compteurs à paiement pour applications intérieures seulement, où le compteur à paiement doit être monté comme en service normal. Les exigences fonctionnelles qui s'appliquent aux compteurs à paiement sont également définies et comportent des exigences fonctionnelles informatives de base et des essais pour le mode de fonctionnement par prépaiement de l'Annexe A. La présente version bilingue (2013-05) correspond à la version anglaise monolingue publiée en 2005-09.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this p
