Povezave med kakovostjo smrekove hlodovine in vizualno oceno trdnostnega razreda žaganega lesa : diplomsko delo - visokošolski strokovni študij = The relationship between spruce round wood quality and a visual assessment of strength class of sawn wood : graduation thesis - higher professional studiesDimc, MatejNamen diplomskega dela je ugotoviti povezave med kakovostjo smrekove hlodovine in vizualno oceno trdnostnega razreda žaganega lesa. Zbrali smo vzorec 1.023 hlodov iz štirih različnih rastišč v ... Sloveniji. Vso hlodovino smo na podlagi standarda SIST EN 1927-1 razvrstili v štiri kakovostne razrede hlodovine A, B, C in D ter jo nato razžagali v sortimente različnih prerezov (38 x 100 mm, 50 x 150 mm, 44 x 210 mm in 140 x 140 mm). Žagani les smo nato po SIST DIN 4074-1 razvrstili v sortirne razrede S13, S10 oz. S7. Ugotovili smo, da med posameznimi rastišči ni bistvenih razlik v kakovosti hlodovine. Hlodovine kakovosti A v preučevanem vzorcu ni bilo, 66 % hlodovine je bilo kakovosti B, 33 % kakovosti C in 1 % kakovosti D. 10 % žaganega lesa je bilo razvrščenega v sortirni razred S13, 41 % v razred S10, 32 % v razred S7, 17 % kosov pa smo uvrstili med izmet. Večina napovedi sortirnih razredov žaganega lesa je bila previsoka (82 % kosov). Menimo, da samo na podlagi razvrstitve hlodovine v kakovostne razrede ne moremo zanesljivo napovedovati, v kateri vizualni trdnostni razred žaganega lesa bodo uvrščeni sortimenti, izdelani iz te hlodovine.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [M.
