Abstract
As a result of the quality tests on plywood, medium density fiberboard(MDF), and newly applied oriented strand board(OSB) as well as those required for use of environment on wood-baed flooring board(SEM, percentage of moisture content for over-dried one, size change, absorbing thickness, impact resistance, formaldehyde, permeability, and heat transfer), plywood showed the most stable quality. OSB and MDF requires solutions from moisture and management for discharging toxic matters such as formaldehyde. For temperature rising and diffusion according to heat transfer by board, all of them showed the similar results and yet, the board using MDF with additional materials should be improved with heating efficiency. Therefore, in case that there are different characteristics from those by board type, it is necessary to establish criteria individually or by product according to types of boards, and to prepare for detailed standards.
