This document addresses the design and development of fuelling protocols for compressed hydrogen gas dispensing to vehicles with compressed hydrogen storage of fuel. The document does not address dispensing of compressed hydrogen gas to vehicles with hydride-based hydrogen storage systems as well as the dispensing of liquefied or cryo-compressed hydrogen. This document is intended to be used for…

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 document1 specifies the framework, concepts, methodology for testing, and criteria to be achieved to claim compliance to Rec. ITU-T T.800 | ISO/IEC 15444-1 or Rec. ITU-T T.814 | ISO/IEC 15444-15. It provides a framework for specifying abstract test suites (ATSs) and for defining the procedures to be followed during compliance testing. This document: ‒      specifies compliance testing…

IEC 60794-1-213:2024 defines test procedures to be used in establishing uniform requirements for the environmental performance of microduct. The test determines the capability of the microduct to withstand internal pressure without leakage and visible damage. This document applies to microduct used for installation of microduct cable or fibre unit by blowing. Throughout this document, the wording…

IEC 62153-4-3:2013+AMD1:2024 CSV determines the screening effectiveness of a cable shield by applying a well-defined current and voltage to the screen of the cable and measuring the induced voltage in order to determine the surface transfer impedance. This test measures only the magnetic component of the transfer impedance. This second edition cancels and replaces the first edition published in…

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 is part of the ISO 11890 series, dealing with the sampling and testing of coating materials and their raw materials. This document is applicable to the determination of volatile organic compound (VOC) content in the following cases: —     case 1: where there are single-pack coating materials other than case 3, and the expected VOC content is greater than a mass fraction of 5 %,…

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…

This document specifies a test method for the temperature coefficient of refractive index of optical glass using interferometry. Temperature changes in optical glass lead to changes in the optical path length. The change in optical path length can be measured with an interferometer using the number of cycles of light/dark change of the interference stripe. This document defines a test method to…
