This mat is lapped with plastic film that works as a damp-proof course. Fire safety is an important concern because our panels consist of woods havings with gaps between them and other flammable raw materials. This paper describes fire tests conducted with a 50-\nmm-thick, small-scale specimen in order to obtain basic information about the fire resistance of our panels.\nTwo types of fire tests were conducted: one type involved direct heating from one surface, and the other involved indirect heating using a 12.5-mm-thick plaster board as a cover. The small vertical furnace that was used provided a heating temperature that almost satisfied the heating curve specified in the ISO 834 standard. The results revealed that 12 min of direct heating caused charring to a depth of 25 to 30 mm; however, the unexposed side (rear surface)temperature was approximately 80℃. In the case of indirect heating, such a charring depth required 30 min of heating with the rear surface temperature maintained below 80℃ during the heating time. Fiberglass insulation materials were also tested by indirect heating for the purpose of comparison. The rear surface temperature of a 50-mm-thick fiberglass with a density of 16kg/㎥ was　found　to　be　158℃ after heating for 30 min; this suggests that our panels exhibit higher heat shielding performance than the\nfiberglass. It is clear that the charring layer acted as an insulator. Interestingly, moisture content measurements revealed that some of the water that remained near the rear surface of the panels provided heat shielding.","subitem_description_type":"Other"}]},"item_41_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"SEKINO, Noboru"}]},{"nameIdentifiers":[{}],"names":[{"name":"YOSHIBA, Megumi"}]},{"nameIdentifiers":[{}],"names":[{"name":"TANIUCHI, Hironori"}]},{"nameIdentifiers":[{}],"names":[{"name":"YAMAUCHI, Go"}]}]},"item_41_publisher_14":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"岩手大学農学部附属寒冷フィールドサイエンス教育研究センター"}]},"item_41_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0286-4339","subitem_source_identifier_type":"ISSN"}]},"item_41_text_4":{"attribute_name":"著者(機関)","attribute_value_mlt":[{"subitem_text_value":"岩手大学農学部農林環境科学科森林科学講座"},{"subitem_text_value":"岩手大学農学部農林環境科学科森林科学講座"},{"subitem_text_value":"岩手県林業技術センター林産利用部"},{"subitem_text_value":"（株）ヤマウチ"}]},"item_41_version_type_27":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"関野, 登"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"葭葉, 恵"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"谷内, 博規"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山内, 剛"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-11-14"}],"displaytype":"detail","filename":"biuf-n38p1-21.pdf","filesize":[{"value":"2.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"biuf-n38p1-21.pdf","url":"https://iwate-u.repo.nii.ac.jp/record/8990/files/biuf-n38p1-21.pdf"},"version_id":"7289f4b3-888d-4692-b3c3-eeb3742ed008"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"木質小片断熱材の防火性能に関する基礎的研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"木質小片断熱材の防火性能に関する基礎的研究"}]},"item_type_id":"41","owner":"3","path":["1506"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-08-17"},"publish_date":"2011-08-17","publish_status":"0","recid":"8990","relation_version_is_last":true,"title":["木質小片断熱材の防火性能に関する基礎的研究"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T11:19:49.801094+00:00"}
