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…

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.,…

1.1 This standard sets forth minimum requirements for metallic and nonmetallic safety cans: a) With a maximum capacity of 5.3 US gallons (20 L); b) With a minimum capacity of 8 US fl oz (236 mL); c) That are intended to store and handle flammable and combustible liquids; d) That are intended for commercial and industrial applications; and e) That are equipped with self-closing lids or valves…

This document provides a system for the identification and presentation of information about freight containers. The identification system is intended for general application, for example in documentation, control and communications (including automatic data processing systems), as well as for display on the containers themselves. The methods of displaying identification and certain other data (…

fireplaces and appliances intended to be vented through the throat of a masonry fireplace. These appliances are designed for burning solid fuels such as wood and coal. 1.2 This Standard covers catalytic combustors utilized with fireplace inserts. 1.3 Fireplace inserts and hearth-mounted stoves as covered by this standard are not certified for installation in factory-built fireplaces within…

1.1 La présente norme s’applique aux poêles sur socle et aux foyers encastrables préfabriqués pour les foyers en maçonnerie et les appareils dans lesquels l’évacuation d’air se fait par la gorge du foyer en maçonnerie. Ces appareils sont conçus pour brûler des combustibles solides comme du bois et du charbon. 1.2 Cette norme porte sur les chambres de combustion catalytiques utilisées avec les…

1.1 These requirements apply to Factory-Built Type A Chimneys, which do not require field fabrication. The chimneys are typically intended for use with gas and liquid fuel-fired residential appliances and building heating equipment, where the appliance or equipment flue-gas temperatures do not exceed 540 °C. 1.2 The chimneys are typically intended for use in accordance with regulatory Codes,…

1.1 These requirements apply to factory-built chimney assemblies which do not require field fabrication. 1.2 The factory-built chimney assemblies are for use with gas, liquid and solid fuel-fired residential appliances and building heating equipment, where the flue-gas temperatures normally do not exceed 650 ºC. 1.3 The factory-built chimney assemblies are intended for installation and use in…
