Adhesives for load bearing timber structures other than phenolic and aminoplastic - Test methods - Part 4: Determination of open assembly time for one component polyurethane adhesives
This document specifies a method of determining the open assembly time in a standard climate.This document is intended to determine the open assembly time for one component polyurethane adhesives using a defined procedure for obtaining a reliable base for comparison of open assembly time between adhesives. The method gives a result that cannot be applied to the safe manufacture of timber structures without taking into account the influence of factors such as timber density/moisture content, factory temperature and relative air humidity.
