This study was performed to test the combustive properties of the pipe insulation materials which are mainly used in the industries and buildings. Fire characteristic test of pipe insulation film according to the KS F ISO 5660-1 was performed. The experimental materials commonly used in the pipe insulation were used four kinds of films. Two kinds of 4 types of products that have the flame retardant performance and the other two types of them have no flame retardant performance. They were selected for fire characteristic test. The result of finding 25kW/㎡ radiation from the ignition was that flame retardant products were 140sec and the other one were 69sec in average of heat release rate(HRR). The result of flame retardant products in the 50kW/㎡ was 34sec and the other one were 15sec in average of HRR. However, the HRR of flame retardant products was much higher than the other one. Flame propagation test was conducted according to the KOFEIS 1001. The result of flame retardant products was that flame retardant products had a hold without fire spread after firing them. But the other one were completely fired after firing them. Therefore, I want to recommend that flame retardant products need to be used by the regulation to prevent or decrease a fire spread.
