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 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.

This part of IEC 60404 is applicable to surface insulation coatings on electrical steel strip and
sheet classified in IEC 60404-1-1.
This document defines the general principles and technical details of the tests for the
assessment of the thermal endurance of surface insulation coatings on electrical steel strip and
sheet.
The assessment is made by evaluating the change of a specified property of the surface
insulation coating due to a heat treatment at a specified temperature up to 850 °C for a specified
duration time up to 2 500 h. The specified property is measured at an ambient temperature of
(23 ± 5) °C both without heat treatment and after heat treatment.
This document is applicable to the following properties of surface insulation coatings:
– adhesion;
– surface insulation resistance;
– stacking factor.
This document is not applicable to other properties of surface insulation coatings, e.g. welding
properties, or to other effects, e.g. discoloration and off-gassing, which can be caused by
exposure to elevated temperatures.
NOTE Some of the tests take a very long time to perform and therefore they are often not appropriate for acceptance
tests of material supplied on a specific order.
