IEC 61300-2-1:2023 evaluates the effects of vibration on fibre optic devices at the predominant frequency ranges and magnitudes that are encountered during field service on attenuation. NOTE Most vibrations encountered in service are not of a simple harmonic nature. However, it has been shown that tests based on vibrations of this type are satisfactory to simulating actual service. This fourth…
L'IEC 61300-2-1:2023 permet d’apprécier les effets des vibrations sur l’affaiblissement des dispositifs fibroniques pour des plages et amplitudes de fréquences prépondérantes qui sont rencontrées pendant l’intervention sur site. NOTE: La plupart des vibrations rencontrées en service ne sont pas de la nature d’une harmonique simple. Cependant, il a été démontré que les essais utilisant des…
Essai d’émissions acoustiques de pneumatique — Méthode avec un tambour
Le présent document spécifie des méthodes de mesurage des émissions acoustiques issues du contact pneumatique/chaussée, pour des pneumatiques montés sur un appareillage appuyant un pneumatique sur un tambour en rotation tournant en roue libre, c’est-à-dire lorsque le pneumatique tourne en marche libre non motorisée).
Les spécifications données sont destinées à obtenir une corrélation entre les…
This document specifies methods for measuring tyre-to-road sound emissions from tyres fitted on rig that applies the tyre on a rotating drum under coast-by conditions (i.e. when the tyre is in free‑rolling, non‑powered operation).
The specifications are intended to achieve a correlation between results of testing the exterior noise of tyres in a semi anechoic chamber and outdoor testing as…
Solar energy — Calibration of pyranometers by comparison to a reference pyranometer
This document specifies two preferred methods for the calibration of pyranometers using reference pyranometers; indoor (Type A) and outdoor (Type B).
Indoor or type A calibration, is performed against a lamp source, while the outdoor method B, employs natural solar radiation as the source.
Indoor calibration is performed either at normal incidence (type A1), the receiver surface perpendicular to…
