IEC 63044-4:2021 provides the functional safety requirements for HBES/BACS. In addition, it defines functional safety requirements for the interface of equipment intended to be connected to an HBES/BACS network. It does not apply to interfaces to other networks. This document does not provide functional safety requirements for safety-related systems. This document does not provide requirements…

L'IEC 63044-4:2021 spécifie les exigences de sécurité fonctionnelle pour HBES/SGTB. De plus, elle spécifie des exigences de sécurité fonctionnelle relatives à l'interface des équipements destinés à être connectés à un réseau HBES/SGTB. Elle ne s'applique pas aux interfaces avec d'autres réseaux. Le présent document ne spécifie pas d’exigences de sécurité fonctionnelle des…

Le présent document spécifie les dimensions de raccordement principales, ainsi que les exigences de fonctionnement, pour les coupleurs hydrauliques utilisés pour transmettre la puissance hydraulique des tracteurs agricoles aux machines agricoles. Il s'applique aux coupleurs utilisés sur les canalisations hydrauliques, à l'exception des coupleurs utilisés dans les circuits de freinage.…

This document specifies the essential interface dimensions and the operating requirements for hydraulic couplers employed to transmit hydraulic power from agricultural tractors to agricultural machinery. It is applicable to couplers used in hydraulic lines other than those used for braking circuits. NOTE       All hydraulic couplers are intended to be connected and disconnected frequently to…

This document specifies a test method for the determination of the resistance of fire dampers to heat, and for the evaluation of their ability to prevent fire and smoke from spreading from one fire compartment to another through an air distribution system. This document describes the test requirements related to intumescent fire dampers. It is intended for intumescent fire dampers that are…

IEC 62271-213:2021 is applicable to the voltage detecting and indicating system (VDIS) to be installed on indoor and outdoor high-voltage equipment. The VDIS as defined by this document includes a coupling system per phase (capacitive, resistive coupling or other technology) to connect to live parts (main circuit). This first edition cancels and replaces the first edition of IEC 61243-5…

The purpose of IEC 60545:2021 is to establish, in a general way, suitable procedures for commissioning and operation of hydraulic machines and associated equipment, and to indicate how such machines and equipment should be commissioned and operated. Commissioning and operation of the associated equipment are not described in detail in this document but is considered in the commissioning and…

IEC 62878-2-602:2021 specifies the requirements and evaluation methods of electrical connectivity. It is applicable to stacked electronic modules.

IEC 60747-5-13:2021 provides the accelerated test method to assess effects of the tarnishing of silver and silver alloys used for LED packages due to hydrogen sulphide. Particularly, this test method is intended to give information on silver and silver alloy tarnishing effects to the luminous/radiant flux maintenance of LED packages. Additionally, this test method can give information on electric…

IEC 62053-41:2021 applies only to static watt-hour meters of accuracy classes 0,5 and 1 for the measurement of DC electrical energy in DC systems, and it applies to their type tests only. This document applies to electricity metering equipment designed to: • measure and control electrical energy on electrical networks with two poles where one of the poles is connected to earth and with voltage…
