Organic thermal insulation such as cellular polystyrene insulation is mainly used in buildings. Organic thermal insulation is a highly flammable petrochemical material. Because of such characteristics, organic thermal insulation caused fire accident for buildings. The inflammability of cellular polystyrene insulation specified by Korea standard KS M 3808:2011, "Cellular polystyrene(PS) insulation": combustion time ≤ 120 seconds, combustion length ≤ 60 ㎜ through Korea standard KS M ISO 9772:2013, "Cellular plastics - Determination of horizontal burning characteristics of small specimens subjected to a small flame". In this study, horizontal and vertical burning test (KS M ISO 9772 and UL 94 V, respectively) were analyzed about many cellular polystyrene insulations. As a results, horizontal burning test is very little differentiation the flame-retardant performance levels. However, vertical burning test is not like that. To better assess the level of the flame-retardant performance, the current standard needs to be improved.
