Abstract: To prevent improper design and construction of fire compartments through-penetration in buildings, and in order to reinforce public building safety management, all beams, pillars, ceilings, floors, doors, walls, and interior decorative materials must have fireproof properties. Moreover, cable conduits, water pipes, and air ducts located in through-penetration sites within buildings should be properly designed to block the spread of smoke and hot air, thus, reducing losses due to fire disasters. This study used common firestop materials, such as firestop sheets, mineral wool, and two-pack fire barrier foam to conduct 10-min surface burning tests on individual substrates. The flame spread distance and smoke per minute were measured and recorded in order to calculate the Flame Spread Index (FSI) and Smoke Developed Index (SDI). The results showed that all three firestop materials meet with the ASTM E84 Class A.

Abstract: This study tested four types of fireproof and stuffing materials, including firestop sheets, silicone fire barrier sealant, mineral wool batt, and double agent fire barrier foam, on through-floor pipes and walls. Based on the specifications of the American society for testing and materials (ASTM) E84, a 10 min substrate surface burning test was conducted to test fireproof and stuffing materials. The results indicated that the level of fireproof material substrates reached the level of class A in ASTM E84. Combination methods A and B were tested by 180 min heating for specimens, according to the ASTM E814 standard temperature-time (T-t) heating curve, followed by the water spraying test. The results showed that methods A and B have 180 min of fire prevention effects (F rating), and method B can achieve 180 min of heat prevention effects (T rating).
