IEC 60947-2:2016 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 60947-2:2016 applies to circuit-breakers, the main contacts of which are intended to be connected to circuits, the…

IEC 60947-2:2016 applies to circuit-breakers, the main contacts of which 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.; it also contains additional requirements for integrally fused circuit-breakers. This fifth edition cancels and replaces the fourth edition published in 2006, Amendment 1:2009 and Amendment 2:2013. This edition…

ISO 16486-4:2016 specifies the characteristics of valves made from unplasticized polyamide (PA-U) in accordance with ISO 16486‑1, intended to be buried and used for the supply of gaseous fuels. Valves made from other material than unplasticized polyamide designed for the supply of gaseous fuels conforming to the relevant standards are permitted to be used in PA-U piping system according to ISO…

1 Scope This International Standard specifies requirements, including dimensions, for agent-specific filling systems for agent-specific anaesthetic vaporizers. This International Standard does not specify construction materials. NOTE 1 For recommendations on materials, see Annex A. Because of the unique properties of desflurane, dimensions for this agent have not been specified in this…

1.1 This Standard applies to motor-operated food processing appliances intended for use on nominal system voltages of 600 V and less, except that, where appliances are driven by universal type motors or electromagnetic mechanisms, the Scope is limited to appliances rated for use on nominal system voltages of 240 V or less. This Standard applies to appliances designed to be used in accordance…

ISO 7076-6:2016 specifies requirements for compressed air foam systems (CAFS) in which foam concentrate and compressed air are continuously added to the water being discharged from the fire-fighting pump. This part of ISO 7076 is applicable to CAFS that can be permanently installed in fire-fighting vehicles, transportable, or mobile. ISO 7076-6:2016 specifies requirements for CAFS which are used…

IEC 61995-1:2005+A1:2016 applies to devices for the connection of luminaires (DCL) intended for household and similar purposes, for the electrical connection of fixed luminaires to final circuits rated at not more than 16 A without providing mechanical support for the luminaire. DCLs are intended for use according to their IP rating per IEC 60529. This consolidated version consists of the first…

IEC 61803:1999+A1:2010+A2:2016 applies to all line-commutated high-voltage direct current (HVDC) converter stations used for power exchange in utility systems. This standard presumes the use of 12-pulse thyristor converters but can, with due care, also be used for 6-pulse thyristor converters. In some applications, synchronouscompensators or static var compensators (SVC) may be connected to the a…

L'IEC 61803:1999+A1:2010+A2:2016 s'applique à tous les postes de conversion en courant continu à haute tension (CCHT), commutés par le réseau, et utilisés pour l'échange de puissance dans des systèmes de distribution d'énergie. Cette norme présuppose l'utilisation de convertisseurs à thyristors à 12 impulsions mais peut également, en utilisant les précautions appropriées…
