IEC 60335-2-27:2009+A1:2012 deals with the safety of electrical appliances incorporating emitters for exposing the skin to ultraviolet or infrared radiation, for household and similar use, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances. Appliances intended to be used in tanning salons, beauty parlours and similar premises, are also within…

1 SCOPE 1.1 The intent of this fire test method is to determine the integrity of electrical power, data and optical fibre cables which are evaluated for their ability to maintain circuit integrity. 1.2 The electrical power, data and optical fibre cables covered by this Standard are installed to comply with the requirements in the Canadian Electrical Code and the National Building Code of Canada.…

1 Scope This clause of Part 1 is replaced by the following. This International Standard deals with the safety of electric HEAT PUMPS, including SANITARY HOT WATER HEAT PUMPS, AIR-CONDITIONERS, and DEHUMIDIFIERS incorporating motor-compressors and hydronic room FAN COILS, their maximum RATED VOLTAGES being not more than 250 V for single phase appliances and 600 V for all other appliances.…

Scope 1.1 This standard applies to newly produced automatic valves (Section 3, Definitions) constructed entirely of new, unused parts and materials. These valves may be individual automatic valves or valves utilized as parts of automatic gas ignition systems. This standard also applies to commercial/industrial safety shutoff valves (Section 3, Definitions), herein after referred to as C/I…

1 Scope 1.1 This International Standard is applicable to: - flow-metering devices that are connected, either directly or by means of flexible connecting assemblies, and disconnected by the operator at terminal units of a medical gas pipeline system for flow adjustment, measurement and delivery of medical gases; - flow-metering devices that are connected and disconnected by the operator at gas-…

The proportion of Renewable Energies is likely to increase in all major electricity markets. Their large scale incorporation into existing electricity grids will be complex, and their successful integration will likely depend on large-capacity Electrical Energy Storage. This White Paper’s primary goal is to provide a global view on the state of the art and future directions for grid…

Published in the IEC since 1966, the drawings given in this publication represent the unification of national standards. The database version of this publication avails the standard sheets in PDF format and it also provides search facilities for easy…

This part of ISO 23611 provides guidance for the design of field studies with soil invertebrates (e.g. for the monitoring of the quality of a soil as a habitat for organisms). Detailed information on the sampling of the most important soil organisms is provided in the other parts of this International Standard (ISO 23611-1 to ISO 23611-5). This part of ISO 23611 is used for all terrestrial…

Scope 1.1 This Standard is intended to be read together with Annex A, Ref. No. 1. The requirements of Annex A, Ref. No. 1 apply unless modified by this Standard.

Scope 1.1 These requirements cover devices and systems intended for use in accordance with Annex A, Ref. No. 1, to reduce the risk of electric shock to the user from accessible parts, in grounded or isolated circuits for charging electric vehicles. These circuits are external to or on board the vehicle. 1.2 The devices and systems covered by these requirements are compatible with the designs of…
