In this part of the study series, the classification of our sample set is carried out according to the EN 338. A visual pre-grading is presented, to remove the worst specimens and achieve a better final result and a standardized visual grading is also shown. Our results are compared with literature values of clear specimens as well. Amount of 80% of the specimens were found to be suitable for further structural use. The total sample set is classified in strength class D35 (average density 712.6\u00b172.5 kg\/m3; average MoRadj 65.4\u00b116.2 MPa; average MoEadj 13.4\u00b13.1 GPa), while the visually pre-graded part with better average test results is classified in strength class D45. Industrial wood residues contain a sufficiently high proportion of elements for further processing, so that after sorting it can be used as raw material for glued-laminated load-bearing timber.<\/p>\n","protected":false},"author":5,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4581],"tags":[4601,4602,4417,4600,529],"release_year":[],"ppma_author":[4335,4336,2192],"class_list":["post-4636","post","type-post","status-publish","format-standard","hentry","category-wood-research-volume-68-number-3-2023","tag-classification","tag-grading","tag-oak-timber","tag-structural","tag-yield"],"featured_image_src":null,"author_info":{"display_name":"Stela Sl\u00e1mov\u00e1","author_link":"https:\/\/www.woodresearch.sk\/cms\/author\/slamovavupc-sk\/"},"authors":[{"term_id":4335,"user_id":0,"is_guest":1,"slug":"denes-horvath","display_name":"D\u00e9nes Horv\u00e1th","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""},{"term_id":4336,"user_id":0,"is_guest":1,"slug":"sandor-feher-2","display_name":"S\u00e1ndor Feh\u00e9r","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""},{"term_id":2192,"user_id":0,"is_guest":1,"slug":"matyas-bader","display_name":"M\u00e1ty\u00e1s B\u00e1der","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""}],"_links":{"self":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts\/4636","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/comments?post=4636"}],"version-history":[{"count":2,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts\/4636\/revisions"}],"predecessor-version":[{"id":4669,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts\/4636\/revisions\/4669"}],"wp:attachment":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/media?parent=4636"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/categories?post=4636"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/tags?post=4636"},{"taxonomy":"release_year","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/release_year?post=4636"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/ppma_author?post=4636"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
