Fans — Efficiency classification for fans — Part 1: General requirements
This document deals with the classification of fan power consumption and efficiency for many fan types given in the ISO12759 series. In addition, it details specific application efficiency classification information. These procedures are described in ISO 12759-3, ISO 12759-4, ISO 12759-5 and ISO 12759‑6.
This document does not describe a method to compare these classifications and minimum…
Composite hollow insulators - Pressurized and unpressurized insulators for use in electrical equipme...
IEC 61462:2023 applies to composite hollow insulators consisting of a load-bearing insulating tube made of resin-impregnated fibres, a housing (outside the insulating tube) made of elastomeric material (for example silicone or ethylene-propylene) and metal fixing devices at the ends of the insulating tube (see Figure D.1 and Figure D.2 for examples). The object of this document is to define the…
Isolateurs composites creux - Isolateurs avec ou sans pression interne pour utilisation dans des app...
L'IEC 61462:2023 s’applique aux isolateurs composites creux qui sont constitués d’un tube isolant supportant la charge mécanique constitué de fibres imprégnées de résine, protégé par un revêtement en élastomère (par exemple silicone ou éthylène-propylène) et de pièces métalliques fixées à ses extrémités (voir des exemples à la Figure D.1 et à la Figure D.2). Le présent document a pour objet…
Measurement of fluid flow by means of pressure-differential devices — Guidelines for the specificati...
This document describes the geometry and method of use for conical-entrance orifice plates, quarter-circle orifice plates, eccentric orifice plates and Venturi tubes with 10,5° convergent angles. Information is also given for square-edged orifice plates and nozzles under conditions outside the scope of ISO 5167 series.
NOTE The data on which this document is based are limited in some cases.
Mesurage du débit des fluides au moyen d'appareils déprimogènes — Lignes directrices pour la sp...
Le présent document décrit la géométrie et le mode d’emploi des diaphragmes à entrée conique, des diaphragmes quart de cercle, des diaphragmes excentriques et des tubes de Venturi avec un angle de convergent de 10,5°. Des informations sont également données pour les diaphragmes et tuyères à arête rectangulaire utilisés dans des conditions qui sont hors du domaine d’application de la série ISO …
