Acoustics — Measurement of the influence of road surfaces on traffic noise — Part 1: Statistical pas...
This document specifies a method of comparing traffic noise on different road surfaces for various compositions of road traffic for the purpose of evaluating different road surface types. Sound levels representing either light or heavy vehicles at selected speeds are assigned to a certain road surface. The method is applicable to traffic travelling at constant speed, i.e. free-flowing conditions…
Acoustique — Mesurage de l’influence des revêtements de chaussées sur le bruit émis par la circulati...
Le présent document présente une méthode dite «méthode SPB» (de l’anglais «Statistical Pass-By» signifiant statistique au passage) pour la comparaison du bruit émis par la circulation, pour différentes conditions de trafic, sur différents revêtements afin d’évaluer les différents types de revêtements de chaussée. Les niveaux sonores représentant des véhicules légers ou lourds à des vitesses…

- electrical installations of buildings and overhead lines,
- other telecommunication services distribution systems,
-…
Wind energy generation systems - Part 29: Marking and lighting of wind turbines
IEC TS 61400-29:2023, which is a Technical Specification, instils good practice for aviation lighting and marking of wind turbines in both onshore and offshore domains. Consideration is given to visible lighting and infrared (IR) lighting, which is necessary to maintain conspicuity to users of night vision goggles (NVGs). ICAO Annex 14 Standards and Recommended Practices have been used as the…
Solid biofuels — Determination of fines content in pellets
This document specifies a method for determining the amount of material passing through a sieve with 3,15-mm-diameter round holes. It is intended for use in all applications (e.g. laboratories, production sites, field locations) where the measurement of fines is required.
Biocombustibles solides — Détermination de la teneur en fines des granulés
Le présent document spécifie une méthode pour la détermination de la quantité de matériau passant à travers un tamis à trous ronds de 3,15 mm de diamètre. Il est destiné à être utilisé dans toutes les applications (par exemple: laboratoires, sites de production, emplacements sur le terrain) où la mesure des fines est requise.
