ABSTRACT

Many companies provide well-designed furniture, at a low price and in almost all cases this means wood particle boards or fibreboards. Solid wood furniture has become a luxury, thus the market has oriented to the cheaper materials (wood based panels) for furniture manufacturing, so as to broaden the population segment that addresses. These materials, such as, particle board (PB), medium-density fibreboard, (MDF) and plywood contain formaldehyde, which is released in our living spaces in some amount. The acceptable level of formaldehyde emission has decreased dramatically and regulations have been established by some institutions to set emission limits for all products manufacturers. This study aims to analyse the formaldehyde emission from wood based panels found on the Romanian market and its integration in the standard limits. Panels like particle board, fibreboard and plywood were tested in order to evaluate the formaldehyde emission by the gas analyse method at a temperature of 60°C and a constant air flow. It was found that formaldehyde emissions from plywood and PB samples are in the limit permitted by EN 13986:2005 standard, for E1- class. In contrast with these results, emissions from MDF samples were higher, exceeding the standard limits. The issue of formaldehyde emission from these MDF panels is probably related to the bonding adhesives used in the production. Furniture made of these boards could be dangerous for people health, and producers should be aware about the E2 class panels' uses indoor and severe measures of control should be taken into consideration.
