IEC 63370:2022 Lithium-ion batteries and charging systems - Safety IEC 63370:2022 contains a subset of requirements from IEC 62841-1:2014 that are applicable for battery charging systems. The battery charging system includes the battery(ies) and its related charging circuitry. In many cases, the same battery charging system is utilized for a wide variety of end products. Therefore, the purpose of this document is to provide a means for evaluating a battery charging system for electric motor-operated hand-held tools, transportable tools and lawn and garden machinery. This evaluation can then be utilized over a wide range of products covered by IEC 62841 (all parts), without having to re-evaluate the battery charging system for each case where the battery charging system is utilized in or with a product. This document applies to the safety of lithium-ion batteries and charging systems for use in rechargeable battery-powered motor-operated or magnetically driven @ELECTRICALSTANDARD

IEC 60601-2-57:2023 Medical electrical equipment - Part 2-57: Particular requirements for the basic safety and essential performance of non-laser light source equipment intended for therapeutic, diagnostic, monitoring, cosmetic and aesthetic use IEC 60601-2-57:2023 applies to basic safety and essential performance of equipment incorporating one or more sources of optical radiation in the wavelength range 200 nm to 3 000 nm, with the exception of laser radiation, and intended to create photobiological effects in humans for therapeutic, diagnostic, monitoring, and cosmetic or aesthetic applications; hereafter referred to as light source equipment (ls equipment). @ELECTRICALSTANDARD

IEC 60255-27:2023 Measuring relays and protection equipment - Part 27: Product safety requirements IEC 60255-27:2023 specifies the product safety requirements for measuring relays and protection equipment having a rated AC voltage up to 1 000 V, or a rated DC voltage up to 1 500 V. This document specifies essential safety requirements to minimize the risk of fire and hazards caused by electric shock or injury to the user and property. This document specifies only product safety requirements; functional performance of the equipment is not covered. This document covers all the ways in which the equipment can be mounted and used in cabinets, racks and panels. This document also applies to auxiliary devices such as shunts, series resistors, transformers, auxiliary control panels, display devices, etc., that are used in conjunction with measuring relays and protection equipment and are tested together. @ELECTRICALSTANDARD

IEC 60255-26:2023 Measuring relays and protection equipment - Part 26: Electromagnetic compatibility requirements IEC 60255-26:2023 specifies the requirements for electromagnetic compatibility for measuring relays and protection equipment. It is applicable to measuring relays and protection equipment and combinations of devices to form schemes for power system protection including the control, monitoring, communication and process interface equipment used with those systems. This document specifies limits and test methods, for measuring relays and protection equipment in relation to electromagnetic emissions which might cause interference in other equipment. This document specifies the immunity test requirements for measuring relays and protection equipment in relation to continuous and transient, conducted and radiated disturbances, including electrostatic discharges. @ELECTRICALSTANDARD
