  • TEST CRITERIA
    • STABILITY- THE CONSTRUCTION MUST REMAIN STABLE DURING THE PERIOD OF THE FIRE AND MUST NOT COLLAPSE.
    • INTEGRITY- THE CONSTRUCTION MUST MAINTAIN ITS INTEGRITY DURING THE TEST PERIOD SUCH THAT NO GAPS OF SUFFICIENT WIDTH OPEN UP TO ALLOW PENETRATION OF FLAMES.
    • INSULATION- THE FIRE INSULATION PROPERTIES OF THE CONSTRUCTION MUST BE SUCH THAT UNEXPOSED FACE MUST NOT INCREASE IN TEMPERATURE BY MORE THAN AN AVERAGE OF 140°C OR BY MORE THAN 180°C AT ANY ONE POINT FOR THE DURATION OF THE TEST I.E 2 HOURS.
  • PASSIVE FIRE PROTECTION RATINGS
    • STRUCTURAL INTEGRITY (LOAD BEARING) –
      • “A” RATING (CELLULOSIC) = 60 MINUTES.
      • “H” RATING (HYDROCARBON) = 120 MINUTES.
    • NON-LOAD BEARING –
      • “B” RATING FROM 15 MINUTES .
    • INSULATION –
      • “A0” (CELLULOSIC) = 60 MINUTES FIRE PROTECTION + NO INSULATION REQUIRED-NO LIMIT ON BACK FACE.
      • “A60” (CELLULOSIC) = 60 MINUTES FIRE PROTECTION + 60 MINUTES INSULATION-BACK FACE LIMIT REQUIRED.
      • “H0” (HYDROCARBON) = 120 MINUTES FIRE PROTECTION + NO INSULATION REQUIRED.
      • “H60” (HYDROCARBON) = 120 MINUTES FIRE PROTECTION + 60 MINUTES INSULATION.
      • “H120” (HYDROCARBON) = 120 MINUTES FIRE PROTECTION + 120 MINUTES INSULATION.
