Defined by standard <strong>EN 13501-1<\/strong>, it categorizes materials into different classes, from A1 to F, based on their fire behavior : <\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>A1<\/strong> : Non-combustible materials.<\/li>\n\n\n\n<li><strong>A2 :<\/strong> Slightly combustible materials.<\/li>\n\n\n\n<li><strong>B<\/strong> to<strong> D<\/strong> : Materials with increasing combustibility.<\/li>\n\n\n\n<li><strong>E :<\/strong> Easily flammable materials.<\/li>\n\n\n\n<li><strong>F :<\/strong> Materials that are either untested or do not meet the criteria.<\/li>\n<\/ul>\n\n<p>This classification also considers two additional criteria :<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>s<\/strong> (smoke): The amount and speed of smoke production.<\/li>\n\n\n\n<li><strong>d <\/strong>(droplets) : The production of burning droplets or debris.<\/li>\n<\/ul>\n\n<p>For example, a classification of <strong>B-s1,d0 <\/strong>indicates a material with good fire resistance, low smoke production, and no flaming debris projections.<\/p>\n\n<h2 class=\"wp-block-heading\"><strong>Differences Between the French M1 Standard and the Euroclass Standard<\/strong><\/h2>\n\n<p>France has traditionally used a national classification, NF P92-507, commonly known as the <strong>M<\/strong> classification, to evaluate the fire reaction of materials. This system is divided into five categories : <\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>M0 : <\/strong>Non-combustible.<\/li>\n\n\n\n<li><strong>M1 :<\/strong> Combustible but not easily flammable.<\/li>\n\n\n\n<li><strong>M2 :<\/strong> Hardly flammable.<\/li>\n\n\n\n<li><strong>M3 :<\/strong> Moderately flammable.<\/li>\n\n\n\n<li><strong>M4 : <\/strong>Easily flammable.<\/li>\n<\/ul>\n\n<p>The Euroclass and <a href=\"https:\/\/www.alfaflor.com\/en\/treatment-anti-fire-standard-m1-m2-m3-etc-classification-for-eop\/\" data-type=\"post\" data-id=\"123\">M1 standards<\/a> are two separate classifications that assess the fire reaction of materials using different criteria. They coexist and are applied based on regulatory requirements for each project or sector. Some equivalencies exist between both systems.   <\/p>\n\n<div style=\"height:14px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<p>For instance, an M1-rated material generally corresponds to B-s1,d0 in the Euroclass system. However, the <a href=\"https:\/\/www.alfaflor.com\/en\/euroclass-standards-everything-you-need-to-know-about-fire-classification-for-construction-materials\/\">Euroclass standard <\/a>provides a more comprehensive evaluation as it includes additional criteria such as smoke production and flaming debris, offering a more detailed fire behavior assessment. <\/p>\n\n\n\n<p><strong>That said, there is no exact correspondence between these classifications. The equivalencies provided are for reference only, and only laboratory testing can accurately determine a material\u2019s Euroclass rating. <\/strong><\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"715\" src=\"https:\/\/www.alfaflor.com\/wp-content\/uploads\/Norme-euroclasse-1200x715.png\" alt=\"\" class=\"wp-image-25203\" srcset=\"https:\/\/www.alfaflor.com\/wp-content\/uploads\/Norme-euroclasse-1200x715.png 1200w, https:\/\/www.alfaflor.com\/wp-content\/smush-avif\/Norme-euroclasse-600x357.png.avif 600w, https:\/\/www.alfaflor.com\/wp-content\/uploads\/Norme-euroclasse-768x458.png 768w, https:\/\/www.alfaflor.com\/wp-content\/uploads\/Norme-euroclasse-990x590.png 990w, https:\/\/www.alfaflor.com\/wp-content\/uploads\/Norme-euroclasse-441x263.png 441w, https:\/\/www.alfaflor.com\/wp-content\/uploads\/Norme-euroclasse.png 1222w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" data-smush-avif-fallback=\"{&quot;srcset&quot;:&quot;https:\\\/\\\/www.alfaflor.com\\\/wp-content\\\/uploads\\\/Norme-euroclasse-1200x715.png 1200w, https:\\\/\\\/www.alfaflor.com\\\/wp-content\\\/uploads\\\/Norme-euroclasse-600x357.png 600w, https:\\\/\\\/www.alfaflor.com\\\/wp-content\\\/uploads\\\/Norme-euroclasse-768x458.png 768w, https:\\\/\\\/www.alfaflor.com\\\/wp-content\\\/uploads\\\/Norme-euroclasse-990x590.png 990w, https:\\\/\\\/www.alfaflor.com\\\/wp-content\\\/uploads\\\/Norme-euroclasse-441x263.png 441w, https:\\\/\\\/www.alfaflor.com\\\/wp-content\\\/uploads\\\/Norme-euroclasse.png 1222w&quot;}\" \/><\/figure>\n<\/div>\n<\/div>\n\n<h2 class=\"wp-block-heading\"><strong>Alfaflor\u2019s Solutions for Euroclass Compliance<\/strong><\/h2>\n\n<p>To meet Euroclass standard requirements, particularly for wood fireproofing projects, <strong>Alfaflor<\/strong> offers customized solutions :<\/p>\n\n<h3 class=\"wp-block-heading\"><strong>Intumescent Varnish<\/strong><\/h3>\n\n<p>Intumescent varnish is a protective coating that expands when exposed to heat, forming an insulating barrier. This thermal shield slows fire spread and enhances the fire resistance of wooden structures. Applying this varnish helps achieve high Euroclass ratings, such as B,s1-d0, ensuring improved fire safety.  <\/p>\n\n<h3 class=\"wp-block-heading\"><strong>Autoclave Treatment<\/strong><\/h3>\n\n<p>Autoclave treatment involves impregnating wood with fire-retardant products under pressure. This technique ensures deep penetration of fire-resistant agents, enhancing the material\u2019s durability against fire hazards. This process is particularly recommended for exposed or hard-to-reach wood elements, providing long-lasting and effective protection.  <\/p>\n\n<p>In addition to our solutions for Euroclass compliance, we also offer <strong>M1-certified<\/strong> fireproofing products, including: <a href=\"https:\/\/www.alfaflor.com\/en\/catalogue\/fire-retardants\/wood-fire-retardants\/\" data-type=\"product\" data-id=\"102\">Eurobois<\/a>, <a href=\"https:\/\/www.alfaflor.com\/en\/catalogue\/fire-retardants\/textile-fire-retardants\/\" data-type=\"product\" data-id=\"103\">Eurotextil<\/a>, <a href=\"https:\/\/www.alfaflor.com\/en\/boutique\/fire-retardants\/cardboard-fire-retardants\/cardboard-flame-retardant-eurocarton\/\" data-type=\"product\" data-id=\"14817\">Eurocarton<\/a>, and <a href=\"https:\/\/www.alfaflor.com\/en\/catalogue\/fire-retardants\/artificial-plants-fire-retardants\/\" data-type=\"product\" data-id=\"101\">Euroflor<\/a>.<\/p>\n\n<p>Since each project has unique requirements, we encourage our clients to <strong>contact us directly<\/strong> to discuss the best options for their specific needs.
