Abstract

This paper presents data about the firmness of bending of outside corner joints, mountable- demountable and fix, of refined panels of particle board with a width of 25 mm. The research was conducted on two kinds of samples and two different kinds of connective elements. The two kinds of sample objects are divided in two groups according to the way of composition as follows: - group 1: the first are obtained by extraction i.e. cutting up an already constructed element – bedside table which was subjected to a test method for determining firmness, durability and stabilityfurniture for indoor use EN 1730: 2000; - group 2: the second sample objects were not subjected to any tests and were composed of two parts of particle board with given dimensions in accordance with the normative and are connected with the chosen connective objects. In this research the following constructive connections were used: an excentre clutch – minifix with a clamp and an element for tying from the firm Hafele and a plastic corner brace.
