ISO 28902-2:2017 spécifie les exigences et les modes opératoires d'essais de performance relatifs aux techniques de lidar Doppler pulsé hétérodyne et présente leurs avantages et limites. Dans le présent document, le terme «lidar Doppler» s'applique uniquement à des systèmes lidars pulsés hétérodynes permettant d'extraire des mesures du vent à partir de la diffusion d'une…

ISO 28902-2:2017 specifies the requirements and performance test procedures for heterodyne pulsed Doppler lidar techniques and presents their advantages and limitations. The term "Doppler lidar" used in this document applies solely to heterodyne pulsed lidar systems retrieving wind measurements from the scattering of laser light onto aerosols in the atmosphere. A description of…

This Standard sets forth the minimum requirements for containment sumps, and associated sump fittings and accessories (products) intended for below- or at-grade use as an enclosure for housing of, and access to, underground piping, connector piping, and other fueling system components (such as pumps, valves, sensors, wiring, etc.) in addition to temporary containment of typical liquid fuels as…

CISPR TR 16-4-4:2007+AMD1:2017 contains a recommendation on how to deal with statistics of radio interference complaints. Furthermore it describes the calculation of limits for disturbance field strength and voltage for the measurement on a test site based on models for the distribution of disturbances by radiated and conducted coupling. This second edition of CISPR 16-4-4 contains two thoroughly…

IEC 60287-3-1:2017 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 60287-3-1:2017 is applicable to the conditions of steady-state operation of cables at all voltages, buried…

IEC 60287-3-1:2017 is applicable to the conditions of steady-state operation of cables at all voltages, buried directly in the ground, in ducts, troughs or in steel pipes, both with and without partial drying-out of the soil, as well as cables in air. The term "steady state" is intended to mean a continuous constant current (100 % load factor) just sufficient to produce asymptotically…

IEC 60287-3-1:2017 s'applique aux conditions de fonctionnement en régime permanent des câbles de toutes tensions enterrés directement dans le sol, placés dans des fourreaux, caniveaux ou tubes d'acier, avec ou sans assèchement partiel du sol, ainsi que les câbles posés à l'air libre. On entend par "régime permanent" la circulation continue d'un courant constant (…

1.1 This Standard sets forth the minimum requirements for primary, secondary, and coaxial types of flexible connector pipes intended for short length transfer and containment of the specific liquid fuels (or vapours thereof) identified in this Standard, at commercial (public) or fleet (private) automotive motor vehicle fueling stations or similar fuel dispensing applications, and piping systems…

1.1 Installations et lieux de travail concernés Cette norme détermine les caractéristiques d’un système de GSO et de lieux de travail traitant ou entreposant des matières potentiellement dangereuses, soit en raison d’une propriété chimique intrinsèque, biologique, toxicologique ou physique, ou de leur énergie cinétique ou potentielle. 1.2 Exigences minimales relatives au cycle de vie Cette norme…

This part of IEC 61400 specifies a procedure for measuring the power performance characteristics of a single wind turbine and applies to the testing of wind turbines of all types and sizes connected to the electrical power network. In addition, this standard describes a procedure to be used to determine the power performance characteristics of small wind turbines (as defined in IEC 61400-2) when…
