DIN EN 302-7:2004-10

This part of EN 302 specifies a method for determining the conventional working life for adhesives for load-bearing timber structures, by a viscosity test. This method is not suitable for determining the conventional working life of a multi-component adhesive whose actual working life is very short. This document is only intended for obtaining a reliable basis for comparison between adhesives. The method gives results which cannot be applied to the safe manufacture of timber structures without modifications for the influences of factory temperature and relative air humidity.
