The classifications according to the F1four test methods are identified as follows:

  • ENV 1187:2002 test 1: XROOF(t1), where t1 = Burning brand alone,

  • ENV 1187:2002 test 2: XROOF(t2), where t2 = Burning brand + wind,

  • ENV 1187:2002 test 3: XROOF(t3), where t3 = Burning brand + wind + radiation,

  • F2ENV 1187:2002 test 4: X ROOF (t4) where t4 = burning brand + wind + supplementary radiant heat.

TE

  • critical external fire spread time

    • TP

  • critical time to fire penetration

    CLASSES OF EXTERNAL FIRE PERFORMANCE FOR ROOFS/ROOF COVERINGS f1

    The number of classes is still under review and will be amended as soon as the necessary information is available.

    * Attention shall be drawn to dripping from the underside of the specimen, any mechanical failure and any development of holes by adding a suffix “x” to the designation to denote that one or more of these took place during the test. In addition, depending upon inclination of the product during the test, the letters EXT.F will be added to indicate “flat or horizontal” and EXT.S will be added to indicate “inclined”.
