Each establishment is required to have the treatment classification test report to present to the safety commissions. Fire-retardant treatment involves applying a product that limits the material&#8217;s contribution to the development of fire, enabling it to reach the reaction-to-fire classification required for the use concerned.<\/p>\n<h2 id=\"importance-m1-m2-standards\">Importance of M1 and M2 standards and explanation<\/h2>\n<p>The application method validated by the test report for EUROMASSIF BOIS is full immersion in a bath: spray application is not within the scope of the test report.<\/p>\n<p>The M1 and M2 standards are reaction to fire classifications of materials, indicating their behavior in the event of fire. The M1 standard designates a M1-classified material, while the M2 standard corresponds to a hardly flammable material. These standards are crucial because they ensure a high level of safety in public places, thereby reducing risks for occupants. Materials classified M1 or M2 are subject to rigorous tests to assess their fire resistance and their contribution to the spread of flames.<\/p>\n<p>The treatment uses a colourless, odourless liquid product, applied by soaking (immersion) until saturation \u2014 the method validated by the test report. <a href=\"https:\/\/www.alfaflor.com\/en\/boutique\/fire-retardants\/wood-fire-retardants\/5l-fire-retardant-container-for-wood-euromassif-bois\/\">EUROMASSIF BOIS<\/a> carries hazard statement H317 (may cause an allergic skin reaction): wear gloves and eye protection, and refer to the safety data sheet.

LNE test report no. P258195 \u2013 DEC\/3 covers natural softwood of the yellow fir type, raw and untreated, 10 mm thick. The classification does not automatically extend to hardwoods (oak, beech\u2026), wood-based panels (MDF, plywood\u2026), softwood species not comparable to yellow fir, or significantly different thicknesses: any support outside this scope requires prior validation by your inspection body.
