1 Scope This part of IEC 60974 is applicable to power sources for arc welding and allied processes designed for industrial and professional use, and supplied by a voltage not exceeding 1 000 V, battery supplied or driven by mechanical means. This document specifies safety and performance requirements of welding power sources and plasma cutting systems. This document is not applicable to…

1 Domaine d’application La présente partie de l’IEC 60974 s'applique aux sources de courant de soudage à l'arc et aux procédés connexes conçus pour un usage industriel et professionnel qui sont alimentés sous une tension ne dépassant pas 1 000 V, alimentés par batterie ou entraînés par des moyens mécaniques. Le présent document spécifie les exigences de sécurité et de…

This document specifies a method for the determination of the characteristic size of the openings of a single layer of a geotextile or geotextile-related product using the wet-sieving principle.

Le présent document présente une méthode permettant de déterminer la dimension caractéristique des ouvertures d'une couche simple de géotextile ou de produit apparenté selon le principe de tamisage par voie humide.

ISO/IEC 14776-481:2019 defines a device model that is applicable to all SCSI devices. Other command standards expand on the general SCSI device model in ways appropriate to specific types of SCSI devices. ISO/IEC 14776 (all parts) specifies the interfaces, functions, and operations necessary to ensure interoperability between conforming SCSI implementations. This document is a functional…

IEC 62282-8-102:2019 deals with PEM cell/stack assembly units, testing systems, instruments and measuring methods, and test methods to test the performance of PEM cells and stacks in fuel cell mode, electrolysis and/or reversible mode.

IEC 62282-8-102:2019 traite des entités d'assemblage de cellules/piles à membrane échangeuse de protons (PEM – proton exchange membrane), des systèmes d'essai, des instruments et méthodes de mesure, ainsi que des méthodes d'essai destinées à vérifier la performance des cellules et piles à membrane échangeuse de protons en mode pile à combustible, électrolyse et/ou réversible.

ISO/IEC 14776-415:2019 defines a reference model that specifies common behaviors for SCSI devices, and an abstract structure that is generic to all SCSI I/O system implementations.The set of Small Computer System Interface (SCSI) specifies the interfaces, functions, and operations necessary to ensure interoperability between conforming SCSI implementations. This document is a functional…

This document specifies the structure model with related parameters, file format and fitting procedure for characterizing critical dimension (CD) values for wafer and photomask by imaging with a critical dimension scanning electron microscope (CD-SEM) by the model-based library (MBL) method. The method is applicable to linewidth determination for specimen, such as, gate on wafer, photomask,…

This document specifies a method using scanning electron microscopy for determination of the concentration of inorganic fibrous particles in the air. The method specifies the use of gold-coated, capillary-pore, track-etched membrane filters, through which a known volume of air has been drawn. Using energy-dispersive X-ray analysis, the method can discriminate between fibres with compositions…
