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 first edition cancels and replaces IEC 60364-8-2 published in 2018. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to IEC 6036482:2018:
a) the vocabulary and concepts have been aligned as much as possible with those used by TC 8 and SC 8B, taking notably into account the IEC 62898 and IEC 62786 series, still respecting the installers mindset (installers being the first users of the IEC 60364 series and being used to only refer to the IEC 60364 series);
b) the type of system earthing and the change of type of system earthing (sequencing) when there is a change of mode of the prosuming installation, have been clarified;
c) the conditions of connection and disconnection from the DSO network have also been described, both from the safety point of view and the proper functioning point of view;
d) additional requirements have been introduced;
e) the figures have been updated;
f) a new normative Annex D on single dwelling or similar application islandable PEIs has been added;
g) the numbering has also been reviewed to follow the updated numbering system of the IEC 60364 series, in line with the IEC Directives and compatible with Parts 7.

IEC 62055-42:2022, specifies a token generation mechanism and token structure for smart prepayment functionality in markets where IEC 62055-41 compliant systems are not used, and where a different security mechanism is required by project-specific or national requirements. This document specifies token structure, authentication and an anti-replay mechanism, token operating model, and protocol.
This document is informed by the STS Association key management services, and by the key management mechanisms used within the DLMS/COSEM security model within IEC 62056‑6‑2. Reference is made to the international STS token standards (IEC 62055-41, IEC 62055-51 and IEC 62055-52) for payment metering systems, and interworking has been considered where appropriate in terms of token carrier ranges in the decimal domain. IEC 62055-41 tokens and those described in this document are not interoperable, however their domains are designed to be mutually exclusive to ensure the two kinds of tokens do not interfere with each other.
Metering application processing and functionality, HAN interface commands and attributes, WAN interface commands and attributes are outside the scope of this document; however, reference is made to other standards in this regard.
The mechanism for auditing and retrieving data from the meter relating to tariffication, meter readings, profile data and other legal metrology information is outside the scope of this document; however, this is defined as part of any overall metering solution. Such interfaces for retrieving data from a meter may be defined using suitable protocols such as DLMS/COSEM as defined in the IEC 62056 series.

This European Standard describes the method to evaluate the performance of protective systems for electrical cable and busbar systems in order to maintain the circuit integrity under fire conditions to classify the protective system according to EN 13501 3 for the P classification. The test examines the behaviour of cable protection systems exposed to fire from outside. The tests specified in this standard are not aimed for assessing the performance of the fire protective system and the penetration seal for maintaining the requirements of the penetrated wall or ceiling (classification E / I).
This method is very different to EN 50200 for the PH classification and also to IEC 60331-11, IEC 60331-21, IEC 60331-23, and IEC 60331-25, which are not designed for fire protective systems for electrical cable systems.
This standard should be used in conjunction with EN 1363-1.
The test results apply to fire protective systems for electrical cable systems rated for voltages up to 1 kV.
The test procedure should also be used to determine the performance of protective systems for use with data and optical cables, however, verification procedures for such cables are still under development. Proposals are given in Annex C.
The protective system may include ventilation devices, inspection hatches, fixed or removable lids etc.
The tests specified in this standard are not aimed for assessing the performance of sprayed or painted coatings (e.g. intumescent or ablative coating, plastic film, epoxy resin) and similar protective layers (e.g. wrap, bandage) applied directly on the cables or bus bars as fire protective system. Also, cables and bus bars with intrinsic resistance to fire, and without fire protective systems around, are excluded (see CENELEC standard EN 50577).
This test method is not applicable for cabinets for electrical accessory containing bus systems, relays or similar.
The cables identified in this document are for testing only. It is not intended that they shall be used in protective systems installed in buildings.

IEC 62055-31:2022 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.
