Adhesives for load-bearing timber structures - Test methods - Part 7 : determination of the working life under referenced conditions

Le présent document spécifie une méthode permettant de déterminer, à partir d'un essai de viscosité, la durée d'utilisation des adhésifs pour structures portantes en bois dans des conditions de référence. Cette méthode n'est pas applicable pour déterminer la durée d'utilisation d'un adhésif multi-composants dont la durée de vie réelle est très courte. Le présent document vise seulement à fournir une base fiable de comparaison des adhésifs. La méthode fournit des résultats qui ne sont pas applicables sans risque à la fabrication de structures en bois, sans des modifications prenant en compte l'influence de la température et de l'humidité relative de l'air dans l'usine.

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!
