This document specifies a method of determining the minimum pressing time for two glue line thicknesses, close contact glue line and 0,3 mm thick glue line (for gap filling adhesive 1,0 mm), at three temperatures. It is applicable to adhesives used in load- bearing timber structures. This document is only intended for obtaining a reliable base of comparison of pressing time between adhesives. The method gives results that cannot be applied to the safe manufacture of timber structures without modifications for the influences of timber density/absorbency, moisture content, factory temperature and relative air humidity.
