Scope 1.1 These minimum requirements cover equipment for manifolding high-pressure gas cylinders to supply gas for various industrial and commercial applications. Cylinders are manifolded for the purpose of centralizing the gas supply, to provide a continuous supply of gas, or to provide gas at a rate in excess of that which may be obtained from a single cylinder. 1.2 The requirements apply to…

Domaine d’application 1.1 Ces exigences minimales s’appliquent à l’équipement servant au raccord de bonbonnes de gaz sous haute pression pour l’alimentation en gaz dans diverses applications commerciales et industrielles. Les bonbonnes sont reliées à un collecteur afin de centraliser l’approvisionnement en gaz dans le but d’assurer la continuité de l’approvisionnement en gaz ou de distribuer le…

1 Scope 1.1 These requirements cover power-operated equipment for dispensing liquefied petroleum gas into the fuel storage container of a vehicle where the gas is primarily used as an engine fuel. 1.2 The electrical features of power-operated dispensers are as described: a) In the United States: UL 1238, Standard for Control Equipment for Use with Flammable Liquid and LP-Gas Dispensing…

IEC 63364-1:2022 specifies terms, the test method, and the report of sound variation detection system based on IoT. It provides the evaluation method for each part of the sound variation detection system based on IoT in the block diagram, the characterization parameters, symbols, test setups and the conditions. In addition, this document defines the configuration items and criteria of standard…

IEC TS 62607-6-18:2022(E) establishes a standardized method to determine the chemical key control characteristic functional groups for functionalized graphene-based material and graphene oxide by thermogravimetry analysis (TGA) coupled with Fourier transform infrared spectroscopy (FTIR), referred to as TGA-FTIR. The content of functional groups is derived by changes in mass of the…

IEC TR 62595-1-5:2022(E), which is a Technical Report, provides information for the future standardization of the electrical signal interface of LED backlight units for liquid crystal display television sets, which include control signals, control data and LED driver interface. This document only provides information about 2-D local dimming LED backlight units, with or without local boosting.…

IEC TS 62607-6-5:2022(E) establishes a standardized method to determine the key control characteristics contact resistance, and sheet resistance for graphene-based materials and other two-dimensional materials by a transmission line measurement. The method uses test structures applied to the 2D material by photolithographic methods consisting of several metal electrodes with…

This document provides a common approach and guidance to those undertaking assessment of the major safety hazards as part of the planning, design, and operation of LNG facilities onshore and at shoreline using risk-based methods and standards, to enable a safe design and operation of LNG facilities. The environmental risks associated with an LNG release are not addressed in this document. This…

This document specifies a means of uniquely identifying a musical work. It standardizes and promotes internationally the use of a standard identification code so that musical works can be uniquely distinguished from one another within computer databases and related documentation and for the purposes of collecting societies involved in the administration of rights to such works. The International…

IEC 62682:2022 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 62682:2022 edition 2.0 and the previous IEC 62682:2014 edition 1.0. Furthermore, comments from IEC SC 65A experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content…
