IEC 61850-80-6:2026, which is a technical specification, provides a comprehensive overview of the various aspects that need to be considered while using IEC 61850 for information exchange between power system automation equipment and control or maintenance centres or other system level applications. This document:
defines use cases and communication requirements that require an information exchange between power system automation equipment and control or maintenance centres;
describes the usage of the configuration language of IEC 61850‑6;
gives guidelines for the selection of communication services and architectures compatible with IEC 61850;
describes the engineering workflow;
introduces the use of a Proxy/Gateway concept;
describes the links regarding the Specific Communication Service Mapping (SCSM);
defines the abstract conformance test cases that build the basis for the conformance test procedures elaborated by the UCAIug Testing Sub Committee.
This document does not define constraints or limitations for specific device implementations. There is no specific clause for cyber security, which is tackled when it is necessary. The model for IEC TS 61850-80-6 provides security functions based upon the security threats and security functions found in IEC TS 62351-1 and IEC TS 62351-2. This document touches on several security aspects with the following basic assumptions:
Information authentication and integrity (e.g., the ability to provide tamper detection) is needed.
In case of operational issues, encryption (to achieve confidentiality) is optional. This typically applies for GOOSE and SV messages in the power utility automation system LAN.
End-to-end information authentication and integrity methods, regardless of information hierarchies, need to be provided. The typical method to provide this security function is through some type of information/message authentication code. IEC 62351-4 and IEC 62351-9 describe how authentication and integrity is achieved for IEC 61850-8-1. IEC 62351-4 provides means to ensure end-to-end data integrity through Proxy/Gateways.
Beneath information authentication and integrity, information availability is an important aspect for telecontrol. This document provides redundancy architectures to enhance the availability of information in control and maintenance centres

IEC TS 60870-5-601:2015(E) describes test cases for conformance testing of telecontrol equipment, Substation Automation Systems (SAS) and telecontrol systems, including front-end functions of SCADA.

It is expected that using this part of IEC 60870 during testing will minimize the risk of non-interoperability. The goal of this part of IEC 60870 is to enable unambiguous and standardised evaluation of IEC 60870-5 companion standard protocol implementations. The guidelines and conditions for the testing environment are described in IEC 60870-5-6. This new edition includes the following significant technical changes with respect to the previous edition:
- resolving ambiguities and inconsistencies between IEC 0870-5-101:2003 and IEC TS 60870-5-601:2006;
- enhancements and optimisation of test cases which are needed to prove conformance with IEC 60870-5-101:2003.
This publication is to be read in conjunction with IEC 60870-5-101:2003

ISO 11553-2:2026 This document deals with all significant hazards, hazardous situations or hazardous events relevant to hand-held or hand-operated laser processing machines (HLMs), when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. HLM is the machine, as defined in ISO 11553-1:2020, 3.7, in which laser radiation is generated, where the laser provides sufficient energy/power to cause a phase transition in a part of the workpiece and where the laser output or workpiece to be processed is guided manually or hand-held during the laser material processing.
This document defines general design requirements of HLM. HLM includes the laser device, beam-guiding device (e.g. mirror, fibre, lenses), beam-shaping device (e.g. telescope, focusing), and controls. The laser assembly as an integral part of the HLM or only the laser processing head is hand-held or hand-operated during the laser material processing.
This document does not apply
- to laser processing machines which are remotely controlled by a manual controller (hand-operated controller), such as joy sticks, keyboard, etc., without touching a workpiece or a part mechanically connected with the laser material processing head by using the hand(s) of the operator (user)
- to laser processing machines without a drive system which may not belong to machinery. And the laser processing apparatus without moving parts, which may not be considered as machinery in “Type C standard”.
- to medical or cosmetic applications for the treatment of living human or animal tissue;
- to weapon applications, (e.g. such as with regard to military applications, direct close combat.)
NOTE “hand-operated laser processing machine” is synonymous with “hand-guided laser processing machine” in this document. Hand-operated laser processing machines often use manual force reduction means such as wheels, supports, etc., for manual positioning of the laser processing heads or the workpieces.
It is applicable to HLMs using laser radiation to process materials.
The purpose of this document is to draw attention to the hazards related to HLMs and to prevent personal injury. Depending on the application and the location/operating conditions of HLMs, a number of different significant hazards can arise. This document describes both the areas of hazards analysis and risk assessment as well as protective measures.
Requirements dealing with noise as a hazard are covered by ISO 11553-3:2013.
This document does not apply to laser products or equipment manufactured solely or expressly for applications which are excluded from the Scope of ISO 11553-1:2020. This document is not applicable for HLMs which have been manufactured before the date of publication of this standard.
HLMs include the following types:
HLMs which are designed as all-in-one laser assembly including the beam delivery/forming(shaping) system and optional features such as gas nozzles, material (e.g. powder, wire) feed system;
HLMs where the relevant devices are connected by a beam guidance system (e.g. optical fibre) and power/control cables to an external laser assembly device and which includes only the beam delivery/forming(shaping) system and optional features such as gas nozzles, material (e.g. powder, wire) feed system;
laser processing machines where the workpiece is manually moved under/relative to the laser beam (see informative Annex A).
The intended use of HLMs covers both:
movement of elements or workpieces by hand to be processed under/relatively to stationary laser beams as shielded , and
movement of the laser processing head (beam shaping device) by hand to move laser beam(s) over or relative to elements or workpieces to be processed.
Laser processing machines, where laser processing is performed with hand-held or hand-operated workpieces outside the fixed (neither hand-held nor hand-operated by the operator or user) laser processing machines are out of the scope

IEC 61851-23-3:2026 applies to the EV supply equipment to provide energy transfer between the supply network and electric vehicles (EVs), with a rated maximum voltage at side A (supply network side) up to 1 000 V AC or up to 1 500 V DC and a rated maximum voltage at side B (EV side) up to 1 250 V DC.
This document specifies the EV supply equipment of megawatt charging system (MCS) equipped with a coupler according to IEC TS 63379. Systems different to MCS using a coupler specified in IEC TS 63379 are under consideration.
The requirements for bidirectional power flow systems are under consideration.
This document does not cover all safety aspects related to maintenance.
This document specifies systems with protective separation between side A and side B.
The requirements for digital communication between the EV supply equipment and the EV for control of energy transfer are defined in ISO 15118-10 and ISO 15118-20.
EV supply equipment in compliance with this document is not intended to provide energy transfer to a single EV using
– multiple vehicle connectors of the same EV supply equipment, or
– multiple EV supply equipment.
The requirements for such use cases are not specified in this document but are under consideration.
The requirements for EVs mated to EV supply equipment according to this document are specified in ISO 5474-3:2024, Annex B.

IEC 63522-19:2026 This part defines a test method to measure electrical endurance of electrical relays and provides the appropriate severities and conditions for measurements designed to assess the ability of DUTs to perform under expected conditions of transportation, storage and all aspects of operational use.

IEC 63387-1:2026 specifies the methods for evaluating CPV/PV hybrid module performance in terms of power rating. Standard conditions for assessing the power produced by the module and the procedures to measure the power as a function of AOI, irradiance, and temperature are described. A methodology for determining a set of characterization parameter values for the hybrid CPV/PV module (FoV) is also included. In order to compare the performance of different hybrid CPV/PV modules whose output is discontinuous and time-dependent, the concept of effective nominal power is introduced.
This document is applicable to CPV/PV hybrid modules which include both solar cells designed to collect concentrated light (CPV cells array) and solar cells designed to collect diffuse or global light (PV cells array), the latter with bifacial or monofacial illumination. This document applies to hybrid CPV/PV modules with a geometrical concentration ratio > 3x for the CPV cells. For lower geometrical concentration ratio (≤ 3x), the IEC 60904-1 [11] and IEC 61853 series [9] apply.

IEC PAS 61850-90-19:2026 document takes over the IEC 61850 data model specific definitions such as the definition of permissions and their assignment to roles from IEC 62351-8.
The general requirements for Role-Based Access Control (RBAC) are defined in IEC 62351-8. This part of IEC 61850, which is a Publicly Available Specification, applies those requirements to the IEC 61850 environment, including the RBAC modelling considerations, the impacts on IEC 61850 models and protocols, and the resulting engineering process requirements.
Additionally, the binding of permissions to objects is defined to allow an interoperable implementation regarding the semantic of roles. This is achieved by an assignment to unique data objects based on the SCL description. Note that for this, IEC 61850-6:2009+AMD1:2018+AMD2:2024 is a prerequisite as it defined a unique identification of objects in SCL.

IEC 60309-2:2021 applies to plugs, fixed or portable socket-outlets, and appliance inlets, hereinafter referred to as accessories, with a rated operating voltage not exceeding 1 000 V DC or 1 000 V AC with a frequency not exceeding 500 Hz and a rated current not exceeding 125 A, primarily intended for industrial use, either indoors or outdoors.

IEC 60947-5-3:2026 provides additional requirements to those given in IEC 60947-5-2 and IEC 60947-5-1:2024, Annex D (reed contact magnetic switches). It addresses the fault performance aspects of proximity devices with a defined behaviour under fault conditions (PDDB). It does not address any other characteristics that can be required for specific applications.
This document does not apply to protective equipment to directly detect the presence of persons, that are covered by the IEC 61496 series or IEC TS 62998 series.
NOTE 1 A PDDB device can be used to detect indirectly the presence of a person, for example by detecting the position of a platform on which the operator stands (example, garbage trucks).
This document does not specify requirements for the analogue output of PDDB, if any.
This document does not deal with any specific requirements on acoustic noise as the noise emission of proximity devices is not considered to be a relevant hazard.
A PDDB product is intended to be used as sensing subsystem of a safety related control system according to IEC 62061 or ISO 13849-1. Depending on construction principles and complexity, this document is based on product development of the IEC 61508 series to meet the product specific requirements of one or more of the following:
– IEC 61508 series;
– IEC 62061;
– ISO 13849 series.
NOTE 2 The Functional safety device type classification regarding functional safety correlates with IEC 62683-2-3.
This document includes requirements for PDDB when designed for use as part of an interlocking device according to ISO 14119.
This document does not consider aspects of:
– software updates and self-evolving behaviour;
– explosive atmospheres.

IEC TS 61641:2026 identifies methods used to verify the ability of the assembly:
– to limit the risk of injury to personnel during an internal arc-fault;
– to limit the damage to an acceptable level as a result of an internal arc-fault;
– to improve the power availability following an internal arc-fault.
This document takes into consideration:
– the effects of the internal overpressure acting on covers, doors, etc.;
– the thermal effects of the internal arc-fault or its roots on the enclosures and of ejected hot gases and glowing particles.
– the correct function of the IAMS within the assembly;
– the prevention of unintended operation of the IAMS within the assembly, for example caused by switching arcs;
– the functioning behaviour of the IAMS immediately after the assembly is energized.
This document describes different methods to assess the performance of an assembly or zones of an assembly in respect of arcing in air due to an internal failure:
– with "passive" arc-fault protection (provided by mechanical construction, e.g. suitable door locks, hinges, pressure relief devices, barriers);
NOTE 1 This approach corresponds to the method according to IEC TR 61641:2014.
– with "active" arc-fault protection (with the integration of IAMS);
NOTE 2 This approach corresponds to the method according to IEC TS 63107:2020.
– with the use of an arc ignition protected zone (to make the ignition of an arc-fault an extremely remote possibility).
NOTE 3 This approach corresponds to the method according to IEC TR 61641:2014.
IAMS consist of internal arc-fault control devices (IACD), e.g. optical-based IACD's in accordance with IEC 60947-9-2 and internal arc-fault reduction devices (IARD), e.g. arc quenching devices (AQDs) in accordance with IEC 60947-9-1 and short-circuit protection devices SCPD's in accordance with IEC 60947-2 (see Figure EE.1). IAMS can be provided by a combined-type device according to IEC 60947-9-2.
IEC 60364-4-42:2024 (Clause 427) provides guidance on the need for internal arc-fault protection.
This document does not supersede any individual product standard. Individual devices are required to comply with their relevant standard.
This document does not apply to integration of arc fault detection devices (AFDD) according to IEC 62606.
Informative Annex AA gives guidance for the user (see IEC 61439-1:2020, 3.11) on internal arc-fault mitigation.
Informative Annex BB gives guidance for the user (see IEC 61439-1:2020, 3.11) of assemblies with "active" arc-fault protection (with the integration of IAMS).
Informative Annex CC gives guidance for the original manufacturer of an assembly when incorporating an integrated IAMS.
This document does not consider other effects which can constitute a risk, such as emission of toxic gases, loud noises and/or intense light. Furthermore, this document does not consider conditions during maintenance work and the personal protective equipment used.
This edition cancels and replaces IEC TR 61641:2014 and IEC TS 63107:2020. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) Introduction of the term "arcing class zone", using the term "arcing classes" from the previous document IEC TR 61641:2014.
b) Structured using of the terms "zone" and "area". "Area" is used to describe the place of installation and the accessibility of the assembly (macro-environment). "Zone" is used in this document to describe a defined space within the assembly (micro-environment).
c) Assembly protection is classified into two levels.
