Le présent document définit un spectre de bruit ferroviaire normalisé pour l'évaluation et la détermination des performances acoustiques de dispositifs conçus pour réduire le bruit ferroviaire aérien à proximité des voies ferrées. Tous les dispositifs de réduction du bruit autres que les écrans antibruit et dispositifs apparentés agissant sur la propagation du bruit aérien, comme par exemple les dispositifs d'atténuation des vibrations transmises par le sol et les dispositifs embarqués, ne relèvent pas du domaine d'application du présent document.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- 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.

With Requirements, quickly access the main part of the normative text!
