IEC TS 62344:2022 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC TS 62344:2022 applies to the design of earth electrode stations for high-voltage direct current (HVDC) links. It…

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 60079-5:2015+AMD1:2022 contains specific requirements for the construction, testing and marking of electrical equipment, parts of electrical equipment and Ex components in the type of protection powder filling "q", intended for use in explosive gas atmospheres. This standard supplements and modifies the general requirements of IEC 60079-0. Where a requirement of this standard…

This standard supplements and modifies the general requirements of IEC 60079-0. Where a requirement of this standard…

IEC 62841-4-2:2017+AMD1:2022 applies to hand-held hedge trimmers which are designed for use by one operator for trimming hedges and bushes, including extended-reach hedge trimmers with a maximum length of 3,5 m. The rated voltage is not more than 250 V for single-phase a.c. or d.c. tools, and 480 V for three-phase a.c. tools. The rated input is not more than 3 700 W. The limits for the…

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…

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…

IEC 62841-3-10:2015+AMD1:2022 applies to transportable cut-off machines intended to cut materials such as metals, concrete and masonry and to be fitted with one abrasive bonded reinforced wheel of Type 41, or diamond cut-off wheel with the peripheral gaps, if any, not exceeding 10 mm and with a rated no-load speed not exceeding a peripheral speed of the wheel of 100 m/s with the maximum wheel…

1.1 Scope and object This standard applies, when required by the relevant product standard, to low-voltage switchgear and controlgear hereinafter referred to as "equipment" or “device” and 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. This standard states the general rules and common safety requirements for low-voltage…

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…
