To this end, an experimental apparatus was designed to provide the fundamental conditions for one-dimensional heat conduction, under steady state. The boundary conditions were assumed as type 2 on the upper face and type 1 on the rear face of a plate-form sample. A heat flux sensor was placed on the center of the upper face to measure a constant heat flux supplied by electrical resistance. Two type-k thermocouples were positioned to measure the temperature drop between the plate faces. Then, these measures are replaced into a mathematical model to determine the thermal conductivity of the material under analysis. The uncertainty assessment using the Monte Carlo method indicates low dispersion of the thermal conductivity, about 2.00 %, at a confidence level of 95.45 %. This indicates a good precision of the experimental apparatus developed, enabling its application with other non-conductor materials, when the conditions established in the mathematical modelling are strictly followed.<br \/>\n[\/vc_column_text]<\/p>\n<p><span class=\"vc_btn2-container vc_btn2-center\"><br \/>\n<a class=\"vc_general vc_btn3 vc_btn3-size-xl vc_btn3-shape-square vc_btn3-style-classic vc_btn3-color-om-accent-color-3 vc_btn3-icon-left\" href=\"https:\/\/metrologia2021.org.br\/wp-content\/uploads\/2021\/12\/CBM1807_205101.pdf\"><span class=\"vc_btn3-inner\"><i class=\"vc_btn3-icon fa fa-file-pdf-o\"><\/i> Download do Artigo<\/span><\/a><br \/>\n<\/span><br \/>\n[vc_text_separator title=&#8221;V\u00cdDEO&#8221; i_icon_fontawesome=&#8221;fa fa-video-camera&#8221; color=&#8221;om-accent-color-3&#8243; add_icon=&#8221;true&#8221;]<br \/>\n<iframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/FiLipkXDaaU\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe><\/p>\n","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column][vc_text_separator title=&#8221;ARTIGO&#8221; i_icon_fontawesome=&#8221;fa fa-file-pdf-o&#8221; color=&#8221;om-accent-color-3&#8243; add_icon=&#8221;true&#8221;][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]Autores: Jos\u00e9 Ricardo Ferreira Oliveira, Jos\u00e9 Aguiar dos Santos Junior, Vin\u00edcius Soares Medeiros, Gilmar Guimar\u00e3es [\/vc_column_text][vc_separator][vc_column_text]Resumo:The aim of this work&hellip;<\/p>\n<p><a href=\"https:\/\/metrologia2021.org.br\/?p=2140\" class=\"read-more-link\"><span class=\"read-more-icon\"><\/span>Leia mais<\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[1],"tags":[],"_links":{"self":[{"href":"https:\/\/metrologia2021.org.br\/index.php?rest_route=\/wp\/v2\/posts\/2140"}],"collection":[{"href":"https:\/\/metrologia2021.org.br\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/metrologia2021.org.br\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/metrologia2021.org.br\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/metrologia2021.org.br\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=2140"}],"version-history":[{"count":1,"href":"https:\/\/metrologia2021.org.br\/index.php?rest_route=\/wp\/v2\/posts\/2140\/revisions"}],"predecessor-version":[{"id":2141,"href":"https:\/\/metrologia2021.org.br\/index.php?rest_route=\/wp\/v2\/posts\/2140\/revisions\/2141"}],"wp:attachment":[{"href":"https:\/\/metrologia2021.org.br\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=2140"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/metrologia2021.org.br\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=2140"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/metrologia2021.org.br\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=2140"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
