Tests For Firestops
A test has been developed for measuring the performance of firestops, materials and methods in a building designed to resist fire. ASTM, an independent testing organization, has devised a test for firestops, one which is also used for fire walls and floors.
The test uses a prescribed temperaturetime fire exposure, a hose stream application which uses increasing pressure and duration with time of fire exposure, and evaluation criteria which limit flame penetration and unexposed side temperatures.
