Le présent document décrit les méthodes de production, les spécifications, les exigences, les méthodes d'essai, les règles de contrôle, les marques, l'emballage, le transport et le stockage des câbles à fils parallèles en acier préfabriqués, qui sont constitués de fils d'acier haute résistance galvanisés à chaud ou revêtus de zinc-aluminium décrits dans l'ISO 19203.

This document specifies the production methods, specifications, requirements, test methods, inspection rules, marks, packing, transportation and storage for pre-fabricated parallel wire strand (PPWS), which are made of hot-dip galvanized or zinc-aluminium coated high tensile steel wires described in ISO 19203.

This document describes methods for measuring lateral resolution and sharpness in imaging surface chemical analysis. It applies to all methods of surface analysis which use a beam to analyse the chemical composition of surfaces under defined settings of an instrument. It applies to scanning instruments, where a finely focused beam is scanned over the sample in a preselected field of view, as well…

This document provides guidance on reviewing and assessing the implementation and operation of information security controls, including the technical assessment of information system controls, in compliance with an organization's established information security requirements including technical compliance against assessment criteria based on the information security requirements established…

IEC 62364:2019 gives guidelines for: a) presenting data on hydro-abrasive erosion rates on several combinations of water quality, operating conditions, component materials, and component properties collected from a variety of hydro sites; b) developing guidelines for the methods of minimizing hydro-abrasive erosion by modifications to hydraulic design for clean water. These guidelines do not…

L'IEC 62364:2019 donne des lignes directrices pour: a) présenter les données disponibles concernant les taux d'érosion hydro-abrasive avec diverses combinaisons de qualité de l'eau, conditions d'exploitation, matériaux et propriétés des composants; ces données ayant été obtenues sur différents sites hydroélectriques; b) développer des lignes directrices permettant de réduire…

IEC 60691:2015+A1:2019 is applicable to thermal-links intended for incorporation in electrical appliances, electronic equipment and component parts thereof, normally intended for use indoors, in order to protect them against excessive temperatures under abnormal conditions. This standard may be applicable to thermal-links for use under conditions other than indoors, provided that the climatic and…

Le présent document décrit les essais de performance hydraulique (y compris les essais de cavitation) utilisant une pompe de petite taille (centrifuge, hélico-centrifuge ou axiale, ici appelées «modèle réduit de pompe»). Le présent document est utilisé pour les essais de performances des pompes avec un modèle réduit de pompe similaire d'un point de vue géométrique, afin de garantir les…

This document describes hydraulic performance tests (including cavitation tests) using a small size pump (centrifugal, mixed flow or axial pump, hereinafter referred to as a "model pump"). This document is used for pump acceptance tests with a geometrically similar model pump to guarantee the performance of a large size pump manufactured for practical use (hereinafter, a "prototype…
