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.

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

This document applies only to static watt-hour meters of accuracy classes A, B and C for the measurement of direct current electrical active energy in DC systems and it applies to their type tests.
NOTE 1 For general requirements, such as construction, EMC, safety, dependability etc., see the relevant EN 62052 series or EN 62059 series.
This document applies to electricity metering equipment designed to:
- measure and control electrical energy on DC electrical networks with voltages up to 1 500 V;
NOTE 2 Meters for unearthed DC supplies and meters for three-wire DC networks are within the scope of this document.
- form a complete meter including the legally relevant display of measured values;
NOTE 3 Modular meters as described in WELMEC guide 11.7 are included.
- operate with integrated or detached legally relevant displays;
- optionally, provide additional functions other than those for measurement of electrical energy.
They can be used for measuring DC electrical energy, amongst others, in the following application areas:
- in EV (electrical vehicle) charging stations or in EV charging infrastructure (also called EVSE, electric vehicle supply equipment), if energy is measured on the DC side;
- in solar PV (photovoltaic) systems where DC power generation is measured;
- in low voltage DC networks for residential or commercial areas, if energy is measured on the DC side, including similar applications like information technology (IT) server farms or DC supply points for communication equipment;
- in DC supply points for public transport networks (e.g., for trolleybuses);
- in mobile applications on vehicles for e-road (electric road) systems.
Meters designed for operation with external DC instrument transformers or transducers can be tested for compliance with this document only if such meters and their transformers or transducers are tested together and meet the requirements for directly connected meters. Requirements in this document and in EN IEC 62052-11:2021/A11:2022 applying to meters designed for operation with DC LPITs also apply to meters designed for operation with external instrument transformers or transducers.
NOTE 4 Modern electricity meters typically contain additional functions such as measurement of voltage magnitude, current magnitude, power, etc.; measurement of power quality parameters; load control functions; delivery, time, test, accounting, recording functions; data communication interfaces and associated data security functions. The relevant standards for these functions could apply in addition to the requirements of this document. However, the requirements for such functions are outside the scope of this document.
NOTE 5 Product requirements for power metering and monitoring devices (PMDs) and measurement functions such as voltage magnitude, current magnitude, power, etc., are covered in EN IEC 61557 12:2022. However, devices compliant with EN IEC 61557 12:2022 are not intended to be used as billing meters unless they are also compliant with EN IEC 62052-11:2021/A11:2022 and this document.
NOTE 6 Requirements for DC power quality (PQ) instruments, DC PQ measuring techniques, and DC PQ instrument testing are under discussion and will be specified in other standards.

IEC TS 62786-41:2023 (E), which is a Technical Specification, defines minimum requirements for frequency and rate of change of frequency measurements used to control distributed energy resources (DER) and loads connected to electrical power networks.
This document specifies the characteristics of frequency and rate of change of frequency measurements to evaluate their performances. It describes the main use cases of frequency and rate of change of frequency measurements, with associated level of performances. It describes the principle of functional tests to evaluate the specified characteristics and defines the influencing factors that affect these performances, under steady state or dynamic conditions.
This document defines the functional requirements applicable to frequency and rate of change of frequency measurements which can be inside or outside the DER or loads. In the case of DER, this document provides requirements additional to those which are defined in the other parts of IEC 62786 or standards produced by the relevant IEC technical committees (e.g. TC 82 for photovoltaic systems, TC 88 for wind systems, TC 120 for electrical energy storage systems (EES)).
This document is applicable to DER and loads regardless of the voltage level of the point of connection to the grid.

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.

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.
