Marko (fabric) contact with flames and at least one type of heat. Heat contact may take the form of convective, radiant or contact heat, an electric arc, splashes of molten metal, or certain combinations of these types. Marko fabrics must also comply with other standards and are therefore tested for tear resistance, tear strength, burst strength and seam strength. The Marko trademark was later applied to new designs that were developed to address specific risks in the workplace. These include: Marko (fabric) Marko (UNE EN 11612) is a registered trademark for a group of flame retardant fabrics used in the manufacture of
