Innovative test methods for determination of the wood hardness and density

Hardness and density of the wood are considered to be among the most important technical properties of wood flooring. There are standardized methods for determining specified properties, but in factory conditions they are rarely used. The reason is that they require expensive specialized equipment, a large number of test samples, trained staff, and they are relatively long lasting. For these reasons, there was a need for simpler, faster and less expensive method to determine the above mentioned properties of wood. This paper explores the possibility of substitution of the standard methods for determining Brinell hardness with the method of the relative size of the impression (RSI), and also the possibility of substitution of standard test methods for determine wood density (ISO 3131: 1975) with method of measuring the mass of floor elements whose volume is known. The aim of the research is finding a scientifically based, simpler, faster and cheaper ways of determining the aforementioned properties of wood. Innovative methods have proven to be very simple and useful with satisfactory results for practical use.
