Application of statistical methods in glue testing

The use of glue in industry has been increasing lately so the demands for a better quality (at a reasonable price) and a simple application as possible require quick and positive testing. Physical - mechanical properties testing without application of statistical methods is in practice also possible but not statistically reliable. The data acquired by pattern testing taken from everyday use and treated by means of t and F tests and by means of other statistical methods are presented in the article. As can be seen from enclosed examples good and positive testing is only possible by introducing and applying statistical methods.
