Safety of machinery - Requirements for cableless control systems of machinery
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.

High-temperature secondary batteries - Part 1: General requirements
IEC 62984-1:2020 specifies general aspects, definitions and tests for high-temperature secondary batteries for mobile and/or stationary use and whose nominal voltage does not exceed 1 500 V. This document does not cover aircraft batteries, which are covered by IEC 60952 (all parts), or batteries for the propulsion of electric road vehicles, covered by IEC 61982 (all parts).

Electrical energy storage (EES) systems - Part 5-2: Safety requirements for grid-integrated EES systems - Electrochemical-based systems
IEC 62933-5-2:2020 primarily describes safety aspects for people and, where appropriate, safety matters related to the surroundings and living beings for grid-connected energy storage systems where an electrochemical storage subsystem is used.

Household and similar electrical air cleaning appliances - Methods for measuring the performance - Part 1: General requirements
IEC 63086-1:2020 applies to electrically powered household and similar air cleaners intended for use on rated single-phase AC input voltage circuits not exceeding 250 V and DC input voltage circuits not exceeding 48 V. If the test methods in this document are applied to combination products (air conditioners, humidifiers, dehumidifiers, heaters, etc.) with air cleaning function, they are only aimed at their air cleaning function when tested. Battery-operated appliances are within the scope of this document. Dual-supply appliances, either mains-supplied or battery-operated, are regarded as battery-operated appliances when operated in the battery mode. This document is not applicable to: - appliances intended exclusively for industrial purposes; - appliances intended for use in medical treatment locations, such as surgical suites, laboratories, medical treatments rooms, etc. - household range hoods or cooking fume extractors – see IEC 61591. This first edition cancels and replaces IEC PAS 62587 published in 2008.

Digital addressable lighting interface - Part 105: Particular requirements for control gear and control devices - Firmware Transfer
IEC 62386-105:2020 applies to control gear and control devices. Typically, a bus unit according to IEC 62386 (all parts) contains firmware. There are circumstances where it might be necessary to change the firmware after production or shipping of the product. For example if the bus unit does not operate as intended. In such a case, a firmware update of a bus unit via the interface is beneficial. This firmware update process is primarily designed to be a bug fix process, not a feature extension process. Nevertheless the firmware update process can be used for feature extensions. But it is important that the risk of negative effects to the complete system is considered in detail.

Mechanical structures for electrical and electronic equipment - Thermal management for cabinets in accordance with IEC 60297 and IEC 60917 series - Part 6: Air recirculation and bypass of indoor cabinets
IEC 62610-6:2020 deals with thermal management for cabinets in accordance with IEC 60297 and IEC 60917 series, provides compatible measurement methods of recirculation ratio and bypass ratio which are indicators for defining quality of airflow in the forced air cooling that can be commonly applied to indoor cabinets for mounting subrack and/or chassis-based equipment. This document contains the following: a) the definition of recirculation and bypass flow rates in the cooling of the cabinet, b) the levels of the recirculation ratio RC, c) the definition of the formula for the recirculation ratio RCs of forced air cooling subrack and/or chassis-based equipment installed in the cabinet, d) the definition formula of recirculation ratio RCr and bypass rate BPr of the entire cabinet, e) the requirements of the measuring method of each temperature necessary for calculating the recirculation ratio RCs, RCr and bypass ratio BPr. The purpose of this document is to provide: • for the equipment integrator and development designer of the cabinet the criteria for efficiently and co

Dependability reviews during the life cycle
IEC 62960:2020 provides guidance on a review methodology for dependability from a technical perspective that is applicable at all stages of a system life cycle. Its application can improve the dependability of a system throughout its life cycle by triggering appropriate actions at appropriate times to address potential dependability problems. It provides guidance for developers, manufacturers, users and third-party independent reviewers such as consulting organizations. This document describes a dependability review methodology focusing on: - coherence of review activities across life cycle stages and their impact on dependability; - stakeholder identification and how this affects dependability review activities; - the relationships between different types of reviews; - procedures for effective dependability reviews; - examples of dependability review activities.

Secondary cells and batteries containing alkaline or other non-acid electrolytes - Safety requirements for secondary lithium cells and batteries for use in electrical energy storage systems
IEC 63056:2020 specifies requirements and tests for the product safety of secondary lithium cells and batteries used in electrical energy storage systems (Figure 2) with a maximum DC voltage of 1 500 V (nominal). Basic safety requirements for the secondary lithium cells and batteries used in industrial applications are included in IEC 62619. This document provides additional or specific requirements for electrical energy storage systems.
