This standard specifies the procedure for testing the resistance to vertical flame propagation for a single vertical electrical insulated conductor or cable, or optical fibre cable, under fire conditions.

IEC 63172:2020 provides a methodology for determining the energy efficiency class of electrical accessories, to enable the system designer to determine the most efficient components for an electrical installation, also considering all functionalities. This methodology is based on the energy consumption, taking into account the individual functions of the accessory. The energy efficiency class approach contributes to the overall reduction of the energy consumption of an electrical installation.

IEC 62793:2020(E) describes the characteristics of thunderstorm warning systems (TWSs) in order to implement lightning hazard preventive measures. Single sensors and/or a network of sensors (e.g. lightning location system) can be used as a TWS. This second edition cancels and replaces the first edition, published in 2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - portable devices are no...view more

IEC 60050-845:2020 gives the general terminology used in lighting, as well as general terms pertaining to specific applications and associated technologies. This second edition reviews and complements the previous one. It has the status of a horizontal publication in accordance with IEC Guide 108:2006. This terminology is consistent with the terminology developed in the other specialized parts of the IEV.

This document specifies the requirements of the test procedures to be applied for recurrent tests of current-using electrical equipment and appliances for the verification of the effectiveness of the protective measures and the permissible limits for product compliance.
This procedure is applicable to current-using electrical equipment connected to final circuits. They can be either pluggable equipment type A connected to final circuits at work places via a plug or permanently connected equipme...view more

IEC TR 63043:2020(E), which is a technical report, describes common practices and state of the art for renewable energy power forecasting technology, including general data demands, renewable energy power forecasting methods and forecasting error evaluation. For the purposes of this document, renewable energy refers to variable renewable energy, which mainly comprises wind power and photovoltaic (PV) power – these are the focus of the document. Other variable renewable energies, like concentrati...view more

IEC TR 63282:2020(E) collects information and reports experience in order to make recommendations for the standardization of voltage levels and related aspects (power quality, EMC, measurement …) for LVDC systems (systems with voltage level lower than 1 500 V d.c.).
Rationale for the proposed voltage values are given. Variation of parameters for the voltage (power quality) and recommendation for their boundaries are defined. Nevertheless, some of the technical items are not exhaustively explain...view more

EN 60332-3-10:2018 details the apparatus and its arrangement and calibration for methods of test for the assessment of vertical flame spread of vertically mounted bunched wires or cables, electrical or optical, under defined conditions.

IEC 62745:2017(E) specifies requirements for the functionality and interfacing of cableless (for example, radio, infra-red) control systems that provide communication between operator control station(s) and the control system of a machine. Specific requirements are included for such operator control stations that are portable by the operator.

IEC SRD 63268:2020(E) depicts a comprehensive standardization landscape of the interfaces between the main grid stakeholders and the grid users, grid users comprising DERs and Customer Premises.
This document considers the main "physical" and "logical" interactions (i.e. through wires/functions – power and/or communication) between grid users and grid stakeholders, both from an electrical standpoint and from a data standpoint. Then for each interaction type, the document presents the standardiz...view more

This part of IEC 60068 specifies a uniform and reproducible method of confirming that
temperature test chambers conform to the requirements specified in the climatic test procedures
of IEC 60068-2-1 and IEC 60068-2-2, when loaded with either heat-dissipating or non heatdissipating
specimens under conditions which take into account air circulation inside the
working space of the chamber. This document is intended primarily for users when conducting
regular chamber performance monitoring.

IEC 60068-3-7:2020 is available as IEC 60068-3-7:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 60068-3-7:2020 specifies a uniform and reproducible method of confirming that temperature test chambers conform to the requirements specified in the climatic test procedures of IEC 60068-2-1 and IEC 60068-2-2, when loaded with either heat-dissipating or non heat-dissipating specimens under...view more

IEC 62321-10:2020 specifies one normative technique for the determination of polycyclic aromatic hydrocarbons (PAHs) in polymers of electrotechnical products. These PAHs can especially be found in the plastic and rubber parts of a wide range of consumer articles. They are present as impurities in some of the raw materials used in the production of such articles, in particular in extender oils and in carbon black. They are not added intentionally to the articles and do not perform any specific fu...view more

This document defines product category rules (PCR) for electronic and electrical products and systems (EEPS).
It specifies the process and requirements on how to conduct life cycle assessment in the context of
environmental declarations.
PCR is complemented by additional product-specific rules (PSR), which further define e.g. functional units and
default scenarios in the product-specific context. Therefore, it also provides guidance on how to develop PSR
in corresponding technical committee...view more

IEC 62714-4:2020 specifies the integration of logic information as part of an AML model for the data exchange in a heterogenous engineering tool landscape of production systems.
This document specifies three types of logic information: sequencing, behaviour, and interlocking information.
