Sažetak
This paper presents the influence of the orientation of wood cells on the hardness of spruce wood. The hardness measurement was carried out by the measuring method by Brinell, from cross-section to tangential section, in sequences of 15° each. The hardness was measured 10 times for each angle. The results showed that the hardness of wood largely depends on the orientation of the structure. In the cross- section, the highest hardness values were obtained and amounted to 50.0 HB, while the lowest ones were obtained in the tangential section and amounted to 26.1 HB. In the tests carried out, there are relatively large scatterings of results, but the variation coefficients are within the allowable values (10.7 % to 19.8 %). The test precision index ranges between 6.67 % and 12.56 %. The measured hardness values match relatively well with the hardness values calculated by Hankinson's formula.
