IEC 60335-2-106:2021+AMD1:2025 CSV deals with the safety of - portable heated carpets; - heated carpets and similar appliances; - heating units to heat the room in which they are located and that are intended to be installed directly under materials used as a removable floor covering such as carpet, cushion vinyl, or loose laid laminate, their rated voltage being not more than 250 V for…

IEC 61643-11:2025 is applicable to devices for surge protection against indirect and direct effects of lightning or other transient overvoltages. These devices are intended to be connected to AC power circuits and equipment rated up to 1 000 V RMS, the preferred frequencies taken into account in this document are 50/60 Hz. Other frequencies are not excluded. Performance and safety requirements,…

This document specifies the safety requirements for domestic gas cooking appliances. This covers appliances that are freestanding, built-in or table-top and are intended to be used indoors. This document applies to the gas sections of the appliances and their component parts (e.g. combined gas-electric cooking appliances). This document does not apply to: a)       electrical heated elements as…

This document: —     defines a reference land administration domain model (LADM) covering basic information-related components of land registration (including elements above and below the surface of the Earth); —     provides an abstract, conceptual model with three packages and one sub-package related to: —    parties (people and organizations); —    basic administrative units, rights,…

IEC 61643-41:2025 is applicable to devices for surge protection against indirect and direct effects of lightning or other transient overvoltages. These devices are intended to be connected to DC power circuits and equipment rated up to 1 500 V DC. Performance and safety requirements, tests and ratings are specified in this document. These devices contain at least one nonlinear component and are…

This document specifies a test method for measuring in situ the sound absorption coefficient of road surfaces for the one-third octave band frequencies ranging from 250 Hz to 1 600 Hz under normal incidence conditions. If necessary for practical applications the diameter of the tube can be reduced to 80 mm. This will increase the upper boundary of the frequency range to 2 000 Hz one-third octave…

IEC TR 63534:2025 reviews existing theoretical attempts and engineering applications in the area of solar PV systems coupled to LVDC systems. There are three aspects that are identified to be highly relevant to standard compilations: power converters and possible control mechanisms that are eligible for facilitating the interlinking between PV and LVDC networks; local PV system islanding…

This document establishes requirements and recommendations for the design format and data content of a drone or UAS remote pilot and remote crew licence, encompassing both visual human-readable features and machine-readable technologies. By establishing a common basis, this document aims to standardize drone or UAS remote pilot and remote crew licence without impeding the efforts of individual…
