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.

IEC TS 61934:2024(Main)
Electrical insulating materials and systems - Electrical measurement of partial discharges (PD) under short rise time and repetitive voltage impulses

IEC TS 61934:2024 is available as IEC TS 61934:2024 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC TS 61934:2024 is applicable to the off-line electrical measurement of partial discharges (PDs) that occur in electrical insulation systems (EISs) when stressed by repetitive voltage impulses generated from power electronics devices.
Typical applications are EISs belonging to apparatus driven by power electronics, such as motors, inductive reactors, wind turbine generators and the power electronics modules themselves.
NOTE Use of this document with specific products can require the application of additional procedures.
Excluded from the scope of this document are:
- methods based on optical or ultrasonic PD detection,
- fields of application for PD measurements when stressed by non-repetitive impulse voltages such as lightning impulse or switching impulses from switchgear.
This edition includes the following significant technical changes with respect to the previous edition:
a) background information on the progress being made in the field of power electronics including the introduction of wide band gap semiconductor devices has been added to the Introduction;
b) voltage impulse generators; the parameter values of the voltage impulse waveform have been modified to reflect application of wide band gap semiconductor devices.
c) PD detection methods; charge-based measurements are not described in this third edition nor are source-controlled gating techniques to suppress external noise.
d) Since the previous edition in 2011, there have been significant technical advances in this field as evidenced by several hundreds of publications. Consequently, the Bibliography in the 2011 edition has been deleted in this third edition.

Electricity metering data exchange - The DLMS®/COSEM suite - Part 6-1: Object Identification System (OBIS)
SIST 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 62056-6-2:2021; - data transmitted through communication lines; - data displayed on the metering equipment, see Clause A.2. 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

Cores made of soft magnetic materials - Measuring methods - Part 3: Magnetic properties at high excitation level
EN IEC 62044-3:2023

This part of IEC 62044 specifies measuring methods for power loss and amplitude permeability
of magnetic cores forming the closed magnetic circuits intended for use at high excitation levels
in inductors, chokes, transformers and similar devices for power electronics applications.
The methods given in this document can cover the measurement of magnetic properties for
frequencies ranging practically from direct current to 10 MHz, and even possibly higher, for the
calorimetric and reflection methods. The applicability of the individual methods to specific
frequency ranges is dependent on the level of accuracy that is to be obtained.
The methods in this document are basically the most suitable for sine-wave excitations. Other
periodic waveforms can also be used; however, adequate accuracy can only be obtained if the
measuring circuitry and instruments used are able to handle and process the amplitudes and
phases of the signals involved within the frequency spectrum corresponding to the given
magnetic flux density and field strength waveforms with only slightly degraded accuracy.
NOTE It can be necessary for some magnetically soft metallic materials to follow specific general principles,
customary for these materials, related to the preparation of specimens and specified calculations. These principles
are formulated in IEC 60404-8-6.

-   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.
