Fire isolation (class I) The growth of temperature on non-firing surface of construction can not be higher than 140 Celsius degrees (the average value) and 180 Celsius degrees in one point. Smoke-tight (class I) The barrier ability to limit the penetrating smokes and hot fire-gases into the protected part of the building (staircase) through the steppings on the barrier cracks surface. The measure of the smoke-tight is the amount of intensity flow air Q in m3 / h. and is counted on class expressed in minute ( for exapmle S15). |
Fire-resistant class (E) The barrier ability to hold the pressure of flames and the hot gases back during definite in classification time expressed in minutes. The flames on heated side can not appear longer than 10 seconds.
