Electricity metering equipment (AC) - General requirements, tests and test conditions - Part 31: Safety requirements and tests

Electricity metering equipment (AC) - General requirements, tests and test conditions - Part 31: Safety requirements and tests

This part of IEC 62052 specifies product safety requirements for equipment for electrical
energy measurement and control.
NOTE 1 For other requirements, see the relevant standards.
This International Standard applies to newly manufactured metering equipment designed to
measure and control electrical energy on 50 Hz or 60 Hz networks with a voltage up to 600 V,
where all functional elements, including add-on modules are enclosed in or form a single
case.
NOTE 2 The voltage mentioned above is the voltage line-to-neutral derived from nominal voltages. See Table 7.
This International Standard also applies to metering equipment containing supply and load
control switches, but only those which are electromechanical in operation.
NOTE 3 For components and sub-assemblies, see Clause 13.
When such equipment is designed to be installed in a specified matching socket, then the
requirements apply to, and the tests shall be performed on, equipment installed in its
specified matching socket. However, requirements for sockets and inserting / removing the
meters from the socket are outside the scope of this standard.
This International Standard is also applicable to auxiliary input and output circuits.
NOTE 4 Examples are impulse inputs and outputs, control inputs and outputs, circuits for meter data exchange.
In this standard distinction is made between:
• electromechanical meters, static meters and equipment for tariff and load control;
• direct connected, current transformer operated, voltage and current transformer operated
meters;
• protective class I and protective class II equipment;
• wall or cabinet mounted, rack mounted and panel mounted equipment;
• equipment intended for indoor use and outdoor use.
Equipment used in conjunction with equipment for electrical energy measurement and control
may need to comply with additional safety requirements. See also Clause 13.
NOTE 5 Examples are telecommunication modems and customer information units.
This International Standard does not apply to:
• equipment where the voltage line-to-neutral derived from nominal voltages exceeds 600 V;
• portable meters;
NOTE 6 Portable meters are meters that are not permanently connected.
laboratory and mobile meter test equipment;
• reference standard meters.
The safety requirements of this standard are based on the following assumptions:
• metering equipment has been installed correctly;
• metering equipment is used generally by unskilled persons, including meter readers and
consumers of electrical energy. In many cases, it is installed in a way that it is freely
accessible. Its terminal covers cannot be removed and its case cannot be opened without
removing seals and using a tool;
• during normal use all terminal covers, covers and barriers providing protection against
accessing hazardous live parts are in place;
• for installation, configuration, maintenance and repair it may be necessary to remove
terminal cover(s), (a part of) the case or barriers so that hazardous live parts may become
accessible. Such activities are performed by skilled personnel, who have been suitably
trained to be aware of working procedures necessary to ensure safety. Therefore, safety
requirements covering these conditions are out of the Scope of this standard.

Oprema za merjenje električne energije (izmenični tok) - Splošne zahteve, preskusi in pogoji preskušanja - 31. del: Varnostne zahteve in preskusi

Ta del standarda IEC 62052 določa zahteve za varnost izdelka za opremo za merjenje in nadzor električne energije.
OPOMBA 1: za druge zahteve glejte ustrezne standarde.
Ta mednarodni standard se uporablja za novo proizvedeno merilno opremo, zasnovano za merjenje in nadzor električne energije v omrežjih s frekvenco 50 ali 60 Hz in napetostjo do 600 V, pri čemer so vsi funkcionalni elementi, vključno z dodatnimi moduli, v enotnem ohišju.
OPOMBA 2: zgoraj omenjena napetost je napetost med linijskim in nevtralnim vodnikom, izpeljana iz nazivnih napetosti. Glej preglednico 7.
Ta mednarodni standard se uporablja tudi za merilno opremo, ki vsebuje elektromehanska stikala za nadzor napajanja in obremenitve.
OPOMBA 3: za komponente in podsestave glej točko 13.
Ko je taka oprema zasnovana za namestitev v posebej zasnovano vtičnico, zahteve veljajo za opremo, ko je nameščena v vtičnico, in ko je treba opraviti preskuse na opremi. Zahteve za vtičnice ter vstavljanje in odstranjevanje merilnikov iz vtičnice ne spadajo v področje uporabe tega standarda.
Ta mednarodni standard se uporablja tudi za pomožna vhodna in izhodna vezja.
OPOMBA 4: primeri so impulzni vhodi in izhodi, krmilni vhodi in izhodi, vezja za izmenjavo podatkov merilnikov.
Ta standard razlikuje:
• elektromehanične in statične merilnike ter opremo za nadzor tarif in obremenitve;
• neposredno povezane merilnike, merilnike, ki jih upravljajo tokovni transformatorji ter merilnike, ki jih upravljajo napetostni in tokovni transformatorji;
• zaščitno opremo razreda I in II;
• opremo, montirano na zid, v ploščo ali omarice in opremo, nameščeno na stojalo;
• opremo za uporabo v zaprtih prostorih in na prostem.
Oprema, uporabljena skupaj z opremo za merjenje in nadzor električne energije, bo morda morala biti skladna z dodatnimi zahtevami za varnost. Glej tudi točko 13.
OPOMBA 5: primeri so telekomunikacijski modemi in enote za obveščanje strank.
Ta mednarodni standard se ne uporablja za:
• opremo, katere napetost med linijskim in nevtralnim vodnikom, izpeljana iz nazivnih napetosti, presega 600 V;
• prenosne merilnike;
OPOMBA 6: prenosni merilniki so merilniki, ki niso trajno priključeni.
• laboratorijska in mobilna preskusna oprema za merilnike;
• standardni referenčni merilniki.
Varnostne zahteve tega standarda so osnovane na naslednjih predpostavkah:
• merilna oprema je bila pravilno nameščena;
• merilno opremo na splošno uporabljajo neizkušene osebe, vključno z odčitovalci števcev in uporabniki električne energije. V številnih primerih je oprema montirana tako, da je lahko dostopna. Pokrove priključkov se lahko odstrani in omarico se lahko odpre samo, če se odstranijo tesnila, pri čemer je treba uporabiti orodje;
• med običajno uporabo so nameščeni vsi pokrovi priključkov, pokrovi in pregrade, ki zagotavljajo zaščito pred dostopom do nevarnih delov pod napetostjo;
• za montažo, konfiguracijo, vzdrževanje in popravilo je pokrove priključkov, ohišje (ali del ohišja) ali pregrade morda treba odstraniti, tako da je omogočen dostop do nevarnih delov pod napetostjo. Ta dejanja mora opravljati izkušeno osebje, ki je ustrezno usposobljeno in je seznanjeno z delovnimi postopki, potrebnimi za zagotavljanje varnosti. Varnostne zahteve, ki zajemajo te pogoje, tako ne spadajo v področje uporabe tega standarda.

Electricity metering equipment - Particular requirements - Part 41: Static meters for DC energy (classes 0,5 and 1)
EN IEC 62053-41:2024

This part of IEC 62053 applies only to static watt-hour meters of accuracy classes 0,5 and 1 for the measurement of DC electrical energy in DC systems, and it applies to their type tests only.
NOTE 1 For other general requirements, such as safety, dependability, etc., see the relevant parts of IEC 62052 or IEC 62059.
This document applies to electricity metering equipment designed to:
- measure and control electrical energy on electrical networks with two poles where one of the poles is connected to earth and with voltage up to 1 500 V DC;
NOTE 2 There are DC networks with other configurations or with more than 2 poles (for example networks with earth and both a positive and a negative pole).
- have all functional elements, including add-on modules, enclosed in, or forming a single meter case with the exception of indicating displays;
- operate with integrated or detached indicating displays, or without an indicating display;
- be installed in a specified matching socket or rack;
- optionally, provide additional functions other than those for measurement of electrical energy.
They may be used for measuring DC electrical energy, amongst others, in the following application areas:
- in EV (electrical vehicle) charging stations or in EV charging infrastructures, if the measurement is placed on the DC side;
- in information technology (IT) server farms;
- in DC supply points for communication equipment;
- in low voltage DC networks for residential or commercial areas, if the measurement is placed on the DC side;
- in solar PV (photovoltaic) systems where DC power generation is measured;

Electricity metering data exchange - The DLMS/COSEM suite - Part 6-1: Object Identification System (OBIS) (IEC 62056-6-1:2023)
EN IEC 62056-6-1:2024

This part of IEC 62056 specifies the overall structure of the OBject Identification System (OBIS)
and the mapping of all commonly used data items in metering equipment to their identification
codes.
OBIS provides a unique identifier for all data within the metering equipment, including not only
measurement values, but also abstract values used for configuration or obtaining information
about the behaviour of the metering equipment. The ID codes defined in this document are used
for the identification of:
• logical names of the various instances of the ICs, or objects, as defined in
IEC 62056‑6‑2:2023;
• data transmitted through communication lines;
• data displayed on the metering equipment, see Clause A.2 in Annex A.
This document applies to all types of metering equipment, such as fully integrated meters,
modular meters, tariff attachments, data concentrators, etc.
To cover metering equipment measuring energy types other than electricity, combined metering
equipment measuring more than one type of energy or metering equipment with several physical
measurement channels, the concepts of medium and channels are introduced. This allows
meter data originating from different sources to be identified. While this document fully defines
the structure of the identification system for other media, the mapping of non-electrical energy
related data items to ID codes is completed separately.
NOTE EN 13757-1:2014 defines identifiers for metering equipment other than electricity: heat cost allocators,
thermal energy, gas, cold water and hot water.

Electricity metering data exchange - The DLMS/COSEM suite - Part 8-12: Communication profile for Low Power Wide Area Networks (LPWAN) (IEC 62056-8-12:2023)
EN IEC 62056-8-12:2023

IEC 62056-8-12:2023 describes the use of DLMS®/COSEM for Low-Power Wide Area Networks (LPWANs). It specifies how the COSEM data model and the DLMS®/COSEM application layer can be used over various LPWAN technologies using an adaptation layer based on IETF RFC 8724, and in particular over LoRaWAN.
This profile is intended to be used with LPWANs as defined in IETF RFC 8724, in particular LoRaWAN. Low-Power Wide Area Networks (LPWANs) are wireless technologies with characteristics such as large coverage areas, low bandwidth, possibly very small packet and application-layer data sizes, and long battery life operation. This document does not provide functionality to manage the lower layers of the LPWANs.
This part of the DLMS®/COSEM suite specifies the communication profile for Low-Power Wide Area Networks (LPWANs).
The DLMS®/COSEM LPWAN communication profiles use connection-less transport layer based on the Internet Standard User Datagram Protocol (UDP) and Internet Protocol (IPv6).
The adaptation layer is based on IETF RFC 8724 which provides both a header compression/decompression mechanism and an optional fragmentation/reassembly mechanism. SCHC compression is based on static context with small context identifier to represent full IPv6/UDP/COSEM wrapper headers. If required, SCHC fragmentation is used to support IPv6 MTU over the LPWAN technologies.
This document follows the rules defined in IEC 62056-5-3:2023, Annex A, and in IEC 62056-1-0, and IEC TS 62056-1-1:2016 for its structure. See also Annex A for examples

Electricity metering - Payment systems - Part 31: Particular requirements - Static payment meters for active energy (classes 0,5, 1 and 2)
EN IEC 62055-31:2022

This part of IEC 62055 applies to newly manufactured, static watt-hour payment meters of
accuracy classes 0,5, 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 supply
control 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 1 000 V (line-to-line voltage for meters for polyphase systems).
It applies to payment meters for indoor application, operating under normal climatic conditions
where the payment meter is mounted as for normal service (i.e. together with a specified
matching socket where applicable).
Payment meters are implementations where all the main functional elements are incorporated
in a single enclosure, together with any specified matching socket. There are also multi-device
payment metering installations where the various main functional elements, such as the
measuring element, the user interface unit, token carrier interface, and the supply control switch
are implemented in more than one enclosure, involving additional interfaces.
Functional requirements that apply to payment meters are also defined in this document, and
include informative basic functional requirements and tests for the prepayment mode of
operation in Annex A. Allowances are made for the relatively wide range of features, options,
alternatives, and implementations that may be found in practice. The diverse nature and
functionality of payment meters prevent the comprehensive specification of detailed test
methods for all of these requirements. However, in this case, the requirements are stated in
such a way that tests can then be formulated to respect and validate the specific functionality
of the payment meter being tested.
This document does not cover specific functionality or performance requirements for circuit
protection, isolation or similar purposes that may be specified through reference to other
specifications or standards. Safety requirements removed from Edition 1.0 have been replaced
with references to the safety requirements now contained in IEC 62052-31:2015, the product
safety standard for newly manufactured electricity meters. In-service safety testing (ISST) is
not covered by IEC 62052-31:2015 and is left to national best practice usually as an extension
of existing in-service testing (IST) of metrology stability.
This document does not cover software requirements. This document covers type-testing
requirements only. For acceptance testing, the requirements given in IEC 62058‑11:2008 and
IEC 62058-31:2008 may be used.
Dependability aspects are addressed in the IEC 62059 series of standards. Additional reliability,
availability, maintenance and life cycle aspects are provided by IEC TC 56.
This document does not cover conformity tests and system compliance tests that may be
required in connection with legal or other requirements of some markets
