In general, flammability tests are used to determine the ignition capacity of a textile material in the presence of pure flame, radiant heat, or a combination of both. They concern all textile products, but particularly personal protective equipment, textile materials and products used in the transportation sector.<\/strong><\/p>\n<\/div><\/div><\/div><\/div><\/div>

Our capabilities for assessing the flammability behaviour of materials include several types of measurements:<\/p>\n

    \n
  • Flame behaviour: damaged length, persistent flame, residual incandescence (ASTM D6413,<\/span> ISO 15025,<\/span> CAN\/CGSB 4.2<\/span> No. 27.10),<\/span> and flame spread rate (MVSS 302);<\/span><\/li>\n
  • Heat behavior;<\/li>\n
  • Measurement of smoke opacity generated by materials exposed to heat, with or without flames (ASTM E662);<\/span><\/li>\n
  • Smoke toxicity;<\/li>\n
  • Radiant panel ratings (ASTM E162<\/span> and ASTM E648);<\/span><\/li>\n
  • Heat capacity (ASTM E1354<\/span> calorimetric cone);<\/li>\n
  • Thermal protection factor – flame and radiant heat (ISO 17492,<\/span> ASTM F2700,<\/span> and NFPA 1971<\/span> and NFPA 2112);<\/span><\/li>\n
  • Thermal protection factor to flame alone (CAN\/CGSB4.2<\/span> No. 78.1,<\/span> ASTM D4108,<\/span> ASTM F1930<\/span> and FlashFireMan\u2122)<\/li>\n
  • Thermal protection factor under radiant heat alone (ASTM F1939<\/span> and NFPA 1977).<\/span><\/li>\n<\/ul>\n

    PERSONAL PROTECTIVE EQUIPMENT (PPE)
    \n<\/span><\/strong>CTT Group has developed a particular expertise in flammability testing adapted for PPE.<\/p>\n

    Beyond the flammability of the material itself, our tests can determine the thermal protection factor of a garment<\/strong>, which is the amount of heat and the rate at which it passes through a material. This data is of vital importance when it comes to, for example, firefighter clothing (NFPA 1971)<\/span><\/strong>.<\/p>\n

    The development of textiles for certain PPE also requires this type of characterization, notably for welders (EN 11611),<\/span> electricians (NFPA 70E,<\/span> ASTM F1506)<\/span> or workers in contact with hydrocarbons (NFPA 2112).<\/span><\/p>\n<\/div>

    CTT Group has developed a unique flammability dummy to measure heat penetration in a garment, the Flash Fireman\u00ae. See it in action in preliminary tests (NFPA 2112<\/span> and ASTM F 1930):<\/span><\/p>\n<\/div>
