Railway applications - Noise emission - Characterisation of the dynamic properties of track sections for pass by noise measurements

Le présent document spécifie une méthode de caractérisation du comportement dynamique de la structure d'une voie, relativement à sa contribution au rayonnement sonore associée au bruit de roulement. Cette méthode est applicable pour évaluer les performances de sections de voies de référence pour le mesurage du bruit des véhicules ferroviaires dans le cadre d'essais d'homologation. Cependant, la méthode n'est pas applicable pour caractériser le comportement vibratoire de voies sur des structures porteuses comme les ponts ou les remblais.

- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
