BAS EN 15416-4:2010

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.
