1 Scope
This document specifies a method for determining the effect on bond strength of damage
to wood fibres caused by the action of acids from the adhesive or primer used in the
gluing process during climatic cycling.
It is applicable to the following applications:
-
a) for assessing the compliance of adhesives with EN 301, EN 15425 and EN 16254;
-
b) for assessing the suitability and quality of adhesives for load-bearing timber structures;
-
c) for determining if the adhesive after bonding has a damaging influence on the strength
of the wood due to chemical action.
This test is intended primarily to obtain performance data for the classification
of adhesives for load-bearing timber structures according to their suitability for
use in defined climatic environments. This test is carried out on Norway spruce (Picea abies L.) or Beech (Fagus sylvatica L.).
This method is not intended to provide data for structural design and does not necessarily
represent the performance of the bonded member in service.
