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 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…

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…

Scope This part of IEC 61400 applies to lightning protection of wind turbine generators and wind power systems. Refer to Annex M guidelines for small wind turbines. This document defines the lightning environment for wind turbines and risk assessment for wind turbines in that environment. It defines requirements for protection of blades, other structural components and electrical and control…

Scope This part of the CSA E60598 series of Standards specifies requirements for recessed luminaires designed to be installed and used on branch circuits not exceeding 600 V nominal in accordance with CSA C22.1, Canadian Electrical Code, Part I. It also specifies requirements for recessed air-handling luminaires for use with heating, ventilating, and air-conditioning systems in accordance…

Scope 1.1 Facilities and worksites affected This Standard identifies the requirements for a PSM system for facilities and worksites handling or storing materials that are potentially hazardous either due to an inherent chemical, biological, toxicological, or physical property of those materials, or due to the material’s potential or kinetic energy. 1.2 Minimum lifecycle requirements This…
