The ultimate purpose of this study is to improve the irrational system related to flame retardant coating performance test of field flame retardant coating articles and to secure the reliability of flame retardant coating through rational flame retardant coating test. To achieve this, the analysis was conducted on the interior finishing materials used in the interior fields and the trends of recent field flame retardant coating, based on the results of flame retardant coating performance test of field flame retardant coating articles which the first-line fire stations have recently conducted. And I attempted to present the methods of field flame retardant coating performance test suitable to current realities and the ways of improvement for securing reliability by analyzing the problems with the methods and procedures of field flame retardant coating articles and the registration system of flame retardant coating business.

EPS sandwich panel contains flame retardants that slow down ignition during fires,reduce the amount of heat generated, and block the spread of combustion. However, if a sandwich panel does not satisfy standards for fire-retardant performance, it may increase damage to property and human life. It is difficult to test the fire-retardant performance of a finishing material with the naked eye, so it is necessary to develop convenient and fast evaluation methods that are convenient and fast. In this study, a fire safety evaluation method for EPS sandwich panel was analyzed using X-ray to detect specific components related to the fire-retardant performance X-ray fluorescence analysis (XRF) indicated that suitable panel products contained more aluminum in comparison to unsuitable products. Gibbsite was identified as the main crystalline material of flame retardant EPS through X-ray diffraction analysis (XRD) and was included in both suitable products and unsuitable products, but there was a difference in crystalline structure. This study was verifies the possibility of evaluating fire-retardant performance using ultimate analysis and crystal analysis through these X-ray methods.

This experimental study shows the combustion characteristics for each coating thickness of water and oil paint which are used as fire retardant paints that prevent fire propagation through cables in underground culverts and trays. To evaluate combustion characteristics, smoke density(ASTM E 662) and Limited Oxygen Index(ASTM D 2863) experiment method was used. As the results of this study, the combustion characteristics of fire retardant paints produced the following : (a) The molt suitable coating thickness of fire retardant paint was 1.5∼2.0 mm in water paint and 0.2 mm in oil paint. (b) Flaming method in experiments of smoke density were found to be higher than Non-flaming method. (c) Water paint has the fire retardant effect and characteristics better than oil paint in measurement results of smoke density and oxygen index. (d) The oxygen index of water and oil fire retardant was able to know that it was satisfied a standard (30 or above).

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/$m^2$ 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/$m^2$ 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.

Four different polymer compounds were manufactured to make cable sheaths for the shipping industry. Two kinds of ethylene vinyl acetate (EVA) as the main matrix polymers and EVA-grafted maleic anhydride (EVA-g-MAH) as the coupling agent were selected for compounding with fire retardant, crosslinking agent, filler, plasticizer, and other additives. The properties of the four compounded materials were investigated with different contents of the fire retardant, silanecoated magnesium dihydroxide (S-MDH). In the rheology evaluation, the $t_{60}$ and ${\Delta}T$ values increased with increasing S-MDH contents. On the other hand, the tensile strength decreased with increasing S-MDH content due to a relative decrease in binder polymers. With increasing S-MDH content, fire resistance increased, but cold resistance showed no obvious enhancement due to the polar effect of vinyl acetate in EVA.

This study was undertaken to evaluate the performance of flame retardant for fire precaution from sparks at welding-cutting process in industry sites such as shipbuilding yard and chemical factory. As the results of the performance experiment, six kinds of welding blanket in samples that are used commercially had enough in the performance of flame retardant. Nevertheless, the performance to fire precaution un welding blanket shows that the coaling product of two kinds with fiber glass is not sufficient. The lower oxygen index to welding blanket is considered that it is more than 30 in domestic standard. We suggested that the performance improvement of flame retardant for welding blanket need continuously, and the guideline of the flame retardant to welding blanket should be considered and established.

In this study, I evaluated toxicity that analyze performance of flame-retardant about flame-retardant painting wood and combustion gas that is based on the toxicity index. Processing condition of flame retardant solution and treatment method of samples didn't affect greatly to performance of flame retardant. Occurrence of combustion gas showed a almost similar result from the sample which spraying flame retardant solution and toxicity corresponds to high level, Hazard Class III, and the flame retardant solution saturation sample which makes put out Hazard Class II which is a low toxicity relatively.

The combustion properties required for fire simulations of multi-layer, multi-component flame retardant cables were measured using a cone calorimeter. The CO and soot yields combustion efficiencies of the flame retardant cables were investigated. TFR-8 (flame retardant PCV and XLPE added), TFR-CVV-SB (flame retardant PCV and general PVC), and VCTF, which are excellent in the flame retardancy of cables, were considered. As the main result, the CO yield (y_CO) of the TFR-8 and TFR-CVV-SB flame retardant cables increased by 23% and 16%, respectively, with increasing incident radiation heat flux from 25 kW/㎡ to 50 kW/㎡. On the other hand, the CO yield of VCTF was not influenced significantly by the changes in radiant heat flux. Finally, the soot yield and combustion efficiency increased as the sheath material (flame retardant performance) was strengthened. Therefore, in a fire environment where various heat fluxes coexist, attention should be paid to the top of the application of the combustion property of the flame retardant cable.
