This National Standard of Canada establishes a classification system and specifies physical property requirements. Test methods to determine the properties for each class of polyethylene sheet material are specified. This document covers a material intended to be used in building construction applications, that may be used above grade or in contact with the ground. The material can provide the…

IEC 60335-2-40:2022 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 60335-2-40:2022 edition 7.0 and the previous IEC 60335-2-40:2018 edition 6.0. Furthermore, comments from IEC SC 61D experts are provided to explain the reasons of the most relevant changes, or to clarify any part…

IEC 60335-2-40:2022 deals with the safety of electric heat pumps, sanitary hot water heat pumps and air conditioners, incorporating motor-compressors as well as hydronic fan coils units, dehumidifiers (with or without motor-compressors), thermoelectric heat pumps and partial units. Their maximum rated voltage being not more than 300 V for single phase appliances and 600 V for multi-phase…

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…

1.1 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 Domaine d’application 1.1 Cette norme s’applique aux gaines électriques de catégories A et B constituées d’une toile de verre tissée très serré et enduites de polymère d’acrylique, de polymère de silicone ou de polymère vinylique (voir le tableau 1 pour les matériaux et les caractéristiques nominales), et destinées à des appareils conçus pour être installés et utilisés conformément au Code…

IEC 60335-2-113:2016+A1:2021 deals with the safety of cosmetic and beauty care appliances incorporating lasers or intense light sources for household and similar purposes, where their operation relies on contact with the skin, their rated voltage being not more than 250 V. Battery-operated appliances and other d.c. supplied appliances are within the scope of this standard. Dual supply appliances…

1 Scope 1.1 These requirements cover single pole locking-type separable attachment plugs, cord connectors, panel inlets, and panel outlets, adapters, and accessories, rated up to a maximum of 800 amperes and up to 600 volts ac or dc and not intended for connection or disconnection under load conditions. 1.2 These devices are intended to provide power from feeders or branch circuits, or are…

1 Scope 1.1 These requirements cover flexible metallic hose supplied with fittings on each end that facilitate connection without twisting the hose. They have a corrugated metal core or a nonmetallic inner core which are covered with a stainless steel braid. They have a nominal inside diameter of not more than 4 in (101 mm) intended for use in piping systems carrying compressed gases, such as…

1 Domaine d’application 1.1 Ces exigences couvrent les tuyaux flexibles métalliques fournis avec deux raccords, un à chaque extrémité, qui facilitent le raccordement sans qu’il faille tordre le tuyau. Les tuyaux sont dotés d’un centre en métal ondulé ou d’un centre intérieur non métallique recouvert d’une tresse en acier inoxydable. Leur diamètre intérieur nominal ne dépasse pas 4 po (101 mm…
