This is irreversible, so the original appearance of the manufactured articles cannot be restored.<\/p>\n<p>However, if the sheet is not too severely affected by oxidation, its mechanical strength is not impacted, so the panel\u2019s general performance is not compromised.<\/p>\n<p>The appearance of initially very small but growing rust spots may indicate that the protective limit has been exceeded, so the steel of the sheet\u2019s body is being attacked. In these situations, the panel\u2019s original performance could be compromised, so it must be replaced.<\/p>\n<p>However, it is important to note that the information above is indicative; occupational safety technicians must assess the objective conditions of each construction site, under their sole responsibility.<\/p>\n<\/div><\/div><\/div><div class=\"fusion-panel fusion-toggle-no-divider fusion-toggle-boxed-mode panel-default fusion-faq-post fusion-faq-post-3064 \"><span class=\"entry-title rich-snippet-hidden\"><b>bare panels<\/b>: can JVP 4&#215;4 flooring be used with no floor covering? <b>YES<\/b>, with caution<\/span><span class=\"vcard rich-snippet-hidden\"><span class=\"fn\"><a href=\"https:\/\/jvph.net\/en\/author\/admin\/\" title=\"Posts by admin\" rel=\"author\">admin<\/a><\/span><\/span><span class=\"updated rich-snippet-hidden\">2021-01-12T15:59:30+01:00<\/span><div class=\"panel-heading\"><h4 class=\"panel-title toggle\"><a data-toggle=\"collapse\" class=\"collapsed\" data-parent=\"#accordian-1\" data-target=\"#collapse-1-3064\" href=\"#collapse-1-3064\"><div class=\"fusion-toggle-icon-wrapper\"><div class=\"fusion-toggle-icon-wrapper-main\"><div class=\"fusion-toggle-icon-wrapper-sub\"><i class=\"fa-fusion-box\" aria-hidden=\"true\"><\/i><\/div><\/div><\/div><div class=\"fusion-toggle-heading\"><b>bare panels<\/b>: can JVP 4&#215;4 flooring be used with no floor covering? <b>YES<\/b>, with caution<\/div><\/a><\/h4><\/div><div id=\"collapse-1-3064\" class=\"panel-collapse collapse\"><div class=\"panel-body toggle-content post-content\"><p>JVP 4&#215;4 panels\u2019 galvanised sheet metal receives no subsequent treatment. However, it can be used with no additional covering provided its use is rigorously assessed in light of the considerations below.<\/p>\n<p>The galvanised sheet\u2019s abrasion resistance is known: since the exposed surface is substantially composed of zinc, it has a Mohs hardness of between 2.5 and 3, and the underlying steel has a Mohs hardness of between 4.5 and 5.<\/p>\n<p>It follows that, since the materials normally constituting road and earth dust are crystalline, with a Mohs hardness of 6 or more, the risks of scraping and scratching the bare sheet by walking are considerable.<\/p>\n<p>When considering using unfinished JVP 4&#215;4 panels, it is important to consider the specific non-slip features of galvanised sheet.<\/p>\n<p>JVP has had third-party laboratories perform slip-resistance testing in accordance with the most common international standards, such as ENV 12633:1-2003, BS 7976-2: 2002 and BCRA Tortus method, which are available on request.<\/p>\n<p>In general, Italian regulations accept Tortus results, so galvanised sheet metal is perfectly appropriate for dry and wet rubber soles and critical for dry leather soles. However, the test results must be assessed by occupational safety engineers, under their sole responsibility.<\/p>\n<\/div><\/div><\/div><div class=\"fusion-panel fusion-toggle-no-divider fusion-toggle-boxed-mode panel-default fusion-faq-post fusion-faq-post-3057 \"><span class=\"entry-title rich-snippet-hidden\"><b>CE mark and DoP<\/b>, is CE marking required for JVP 4&#215;4 systems?
