Road traffic noise reducing devices - Test method for determining the acoustic performance - Part 2 : intrinsic characteristics of airborne sound insulation under diffuse sound field conditions

Le présent document spécifie une méthode d'essai de laboratoire permettant de mesurer la performance intrinsèque d'isolation aux bruits aériens des dispositifs de réduction du bruit conçus pour les routes dans des conditions de réverbération, par exemple à l'intérieur de tunnels ou tranchées profondes ou sous des couvertures. Il traite de l'évaluation de la performance intrinsèque des écrans antibruit qui peuvent raisonnablement être assemblés à l'intérieur de l'installation d'essai décrite dans la NF EN ISO 10140-2 et la NF EN ISO 10140-4.

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!

The Redline + service - standards comparator allows you to easily and simply identify major changes between the current standard and its last canceled version.

At a glance, you will be able to identify the additions, deletions or modifications to a text, table, figure and formula.


The Redlines + service is offered to you on the collection of French standards in force, in French language and in HTML and PDF format.
