IEC 61754-13:2024 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 61754-13:2024 edition 3.0 and the previous IEC 61754-13:2006 edition 2.0. Furthermore, comments from IEC SC 86 B experts are provided to explain the reasons of the most relevant changes, or to clarify any part of…

This document establishes uniform requirements and test procedures for lowering control devices fitted on the boom, intermediate boom and arm cylinders of hydraulic excavators and backhoe loaders to control the rate of drop in the case of a hydraulic line failure or rupture. It is applicable to the lowering control devices of hydraulic excavators and the backhoe equipment of backhoe loaders used…

Le présent document établit des exigences uniformes et des modes opératoires d'essai pour les dispositifs de contrôle d’abaissement montés sur vérin de flèche ou de bras des pelles hydrauliques ou chargeuses pelleteuses pour contrôler le taux de chute en cas de défaillance ou de rupture du circuit hydraulique. Il s'applique aux dispositifs de contrôle d’abaissement des pelles…

IEC 61406-2:2024 complements IEC 61406-1 by providing additional requirements for those cases where data elements are encoded within the Structured Identification Link string with standardized syntax and semantics. In addition, this document covers cases where the uniqueness relates to product types/models or lots/batches. The default assumption is that the Identification Link identifies unique…

IEC 60136:2024 applies primarily to brushes and brush-holders for cylindrical commutators and slip rings for electrical rotating machines. Some clauses of this document may cover other configurations, such as flat commutators or plain disks. It defines the dimensions of brushes and their components, together with their tolerances: - dimensions of brush block (t, a, r), - angles α and β, -…

This document specifies the requirements for flame arresters that prevent flame transmission when explosive gas-air or vapour-air mixtures are present. It establishes uniform principles for the classification, basic construction and information for use, including the marking of flame arresters, and specifies test methods to verify the safety requirements and determine safe limits of use. This…

IEC 61280-4-2:2024 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 62180-4-2:2024 is applicable to the measurements of attenuation and optical return loss of an installed optical…

ISO/IEC 80079-49:2024 specifies the requirements for flame arresters that prevent flame transmission when explosive gas-air or vapour-air mixtures are present. It establishes uniform principles for the classification, basic construction and information for use, including the marking of flame arresters, and specifies test methods to verify the safety requirements and determine safe limits of use…

Le présent document spécifie une méthode de détermination des dimensions de foyers émissifs effectifs supérieurs à 0,1 mm pour des tubes radiogènes dont la tension est inférieure ou égale à 1 000 kV tension radiographique, au moyen de la méthode radiographique par sténopé avec évaluation numérique. La tension appliquée pour ce mesurage est limitée 200 kV pour l’évaluation visuelle du film et peut…

This document specifies a method for the measurement of effective focal spot dimensions above 0,1 mm of X-ray systems up to and including 1 000 kV X-ray voltage by means of the pinhole camera method with digital evaluation. The tube voltage applied for this measurement is restricted to 200 kV for visual film evaluation and can be selected higher than 200 kV if digital detectors are used. The…
