Adhesives for load-bearing timber structures - Test methods - Part 3 : determination of the effect of acid damage to wood fibres by temperature and humidity cycling on the transverse tensile strength

Le présent document décrit une méthode de détermination de l'influence sur la résistance à la rupture d'un joint de l'attaque des fibres de bois provoquée par l'action d'acides contenus dans l'adhésif ou un primaire utilisé lors du processus de collage pendant des cycles climatiques. Il concerne les applications suivantes : évaluation de la conformité des adhésifs à la NF EN 301, à la NF EN 15425 et à la NF EN 16254 ; évaluation de l'aptitude à l'emploi et de la qualité des adhésifs pour les structures portantes en bois ; détermination de l'éventuelle influence nuisible de l'adhésif après collage sur la résistance du bois résultant d'une action chimique.

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.
