1 Scope 1.1 This standard applies to flashlights and lanterns powered by secondary (rechargeable) batteries and general purpose primary (non-rechargeable) batteries with a maximum voltage of 75 V d.c. The terms flashlights and lanterns as used within this standard refer to products that are battery-powered. 1.2 Flashlights and lanterns that are battery-powered and also powered from a line-…

This document specifies requirements for design, dimensions, material, fabrication and production testing of gate, globe, ball/plug and butterfly valve design types used as isolation valves and check valves for low-temperature applications. This document is applicable to isolation valves for use in low and cryogenic temperature service where the design low-temperature service is -50 °C down to –…

IEC/IEEE 63195-1:2022 specifies protocols and test procedures for repeatable and reproducible measurements of power density (PD) that provide conservative estimates of exposure incident to a human head or body due to radio-frequency (RF) electromagnetic field (EMF) transmitting communication devices, with a specified measurement uncertainty. These protocols and procedures apply for exposure…

IIEC TR 61292-1:2022 which is a Technical Report, applies to optical components of optical fibre amplifiers (OFAs). This document provides information about the most relevant parameters of these optical components, especially for erbium doped fibre amplifiers (EDFAs) and fibre Raman amplifiers (FRAs). It provides introductory information for a better understanding operation and applications of…

IEC/IEEE 63195-2:2022 specifies computational procedures for conservative and reproducible computations of power density (PD) incident to a human head or body due to radio-frequency (RF) electromagnetic field (EMF) transmitting devices. The computational procedures described are finite-difference time-domain (FDTD) and finite element methods (FEM), which are computational techniques that can be…

This document describes the consensus standardization process established by the Bureau de normalisation du Québec (BNQ) to meet the accreditation requirements of the standards development organizations of the Standards Council of Canada (SCC). This process is based on the requirements and guidelines set out in the document Canadian Standards Development — Requirements & Guidance —…

1.1 Scope This part of IEC 60947 applies to the types of equipment listed in 1.1.1 and 1.1.2 whose main contacts are intended to be connected to circuits the rated voltage of which does not exceed 1 000 V a.c. or 1 500 V d.c. Starters and/or contactors dealt with in this standard are not normally designed to interrupt short-circuit currents. Therefore, suitable short-circuit protection (see…

1 Scope This standard applies to a.c. semiconductor motor controllers and starters, which may include a series mechanical switching device, intended to be connected to circuits, the rated voltage of which does not exceed 1 000 V a.c. This standard characterizes a.c. semiconductor motor controllers and starters with and without bypass means. AC semiconductor motor controllers and starters…

1.1 Scope and object This part of IEC 60947 applies to control circuit devices and switching elements intended for controlling, signalling, interlocking, etc., of switchgear and controlgear. It applies to control circuit devices having a rated voltage not exceeding 1 000 V a.c. (at a frequency not exceeding 1 000 Hz) or 600 V d.c. However, for operational voltages below 100 V a.c. or d.c.,…

1 Scope Clause 1 of IEC 61058-1:2016 is applicable except as follows: Addition: This document applies to cord switches (mechanical or electronic) for appliances actuated by hand, by foot or by other human activity, to operate or control electrical appliances and other equipment for household or similar purposes with a rated voltage not exceeding 250 V and a rated current not exceeding 16 A…
