In this research, aluminum composite panels of the general materials and fire retardant materials as building claddings make researches about fire performance comparison analysis. Test methods of the small and medium cone calorimeter experiments and SBI (Single Burning Item) experiments was applied to the determination. As a result, in the experiments peak heat release rate cone calorimeter the general aluminum composite panel $1,293kW/m^2$ ($75kW/m^2$), flame-retardant aluminum composite panel $70kW/m^2$ ($75kW/m^2$) was measured. In the SBI experiments fire growth rate the general fire aluminum composite panel is approximately 743 W/s and the flame-retardant aluminum composite panel is approximately 97 W/s of the value were measured. Thus, a standards enactment are urgently required in this case it is used as building claddings of the aluminum composite panel by fire risk assessment.

With the recent increase in the spread of ESS (Electric Storage System), the damage to human life and property is also rapidly increasing due to continuous fires caused by ESS. In the manufacture of urethane sandwich panels used in ESS, it is necessary to improve the flame retardant performance. In this study, in order to realize the flame retardant properties of flexible polyurethane foam, the effect of the tissue density of the product due to the change of the isocyanate functional group parameter that changes the physical properties of the product on the fire performance was studied. The product was manufactured by changing the density of the urethane structure, and combustion performance tests, gas toxicity tests, and smoke density tests were performed. As a result, it was confirmed that the total amount of heat released had excellent performance when the isocyanate functional group was high, and had no correlation with the maximum heat release rate. When the value of the isocyanate functional group was 2.7 or more, the collapse of the shape could be prevented. In the gas hazard test, the performance was increased when the isocyanate functional group was relatively high, so a flame retardant for the Char system, which had a dense structure and easy to form a carbonized film, was added. confirmed to be. Therefore, as a result of this study, it is thought that it will be possible to lay the foundation for the development of a flame retardant to replace the cheap urethane sandwich panel used in the past.

The earlier studies on the fire resistance performance of woods used as building materials have focused on confirming combustion characteristics of fire retardant or flame resistant treated wood. In this paper, to confirm internal temperature changes closely related to pyrolysis of woods exposed to the flame, heating experiments were conducted in a heating furnace according to the standard heating temperature curves after Douglas-fir, which is widely used as structural materials, was treated with a flame resistant solution and flame retardant paint. As a result of the experiment, it was confirmed that the thermal diffusion inside the wood has decreased when the wood was treated with the flame resistant solution. However, in high temperature, the flame resistant effect could not be expected due to the peeling of the coating in the case of the flame resistant paint treated wood. Therefore, it can be considered that it is more effective to use the flame resistant solution which penetrates in to the inside of the wood than flame resistant paint which forms the coating on the surface of the wood in order to enhance the flame resistance effect on the thick wood.

Due to the construction technique (or the construction culture) growth in and out of Korea, newly-developed products have been continuously released. Furthermore, all legislation and regulation that the World follows are gradually becoming unified. (e.g. FTA(Free Trade Agreement) with the United States was contracted, and inevitable FTA contraction with EU and China ), For this reason, it is considered that Korean fire regulation on building interior materials needs to be reviewed and compared with that of international standard so that it becomes legitimate and reasonable one. Especially, this reference is going to make a description of building interior materials' Flame retardant performance standard.

방염대상물품의 방염성능을 평가함에 있어서 건축물의 내장재로 활용되어지는 목재의 경우 방염액 또는 방염필름 등을 활용한 직접적인 방염처리방법을 많이 활용하고 있는데 방염성능을 평가하는 기준으로는 잔염시간, 잔신시간, 탄화길이, 탄화면적 등의 수치가 기준을 만족하여야 하는데 목재를 활용한 합판에 적용되어지는 방염처리방법에 따라 성능기준의 모호성이 나타날 수 있기 때문에 방염성능의 적합여부를 판단하기 어려운 점이 있어 이에 대해 실험적으로 고찰한 결과를 살펴보았다.

Fire protection for nuclear power plants should be designed according to the concept of "Defense in Depth" to achieve the reactor safety shutdown. This concept focuses on fire prevention, fire suppression and safe shutdown. Fire prevention is the first line of "Defense in Depth" and the licensee should establish administrative measures to minimize the potential for fire to occur. Administrative measures should include procedures to control handling and use of combustibles. Electrical cables is the major contributor of fire loads in nuclear power plants, therefore electrical cables should be fire retardant. Electrical cables installed in nuclear power plants should pass the flame test in IEEE-383 standard in accordance with NUREG-0800, "Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants". To assure the fire retardant of electrical cables during design life, both aged and unaged cable specimens should be tested in accordance with IEEE-383. It can be generally thought that the flammability of electrical cables has been increased by wearing as time passed, however the results from fire retardant tests performed in U.S.A and Korea indicate the inconsistent tendency of aging and consequential decrease in flammability. In this study, it is expected that the effective methodology for validation of fire retardant performance would be identified through the review of the results from fire retardant tests.

After the installation of electric cables at block, PE(pre-erection) and hull stages, the coating stains on the electric cable sheath were unavoidably occurred by additional painting process. According to class rules paint or coating applied on the electric cables shall not adversely affect the mechanical, chemical of fire resistant characteristics of the electric cable sheath. However, there has not been quantitatively studied about the effect of coating stains on properties of sheath materials. In this study, we tried to investigate the effect of coating stains on the performance and deterioration of sheath materials by using FTIR, SEM analysis, flame retardant, high potential voltage and tensile test. The results sowed that coating stains, which were occurred during painting work on site could not adversely affect on the performance and deterioration of sheath materials.

As interest in the eco-friendly ships and lightweight equipment is increasing in the shipbuilding and marine industry, composite materials are applied to equipment such as pipes. In this study, a basalt fiber reinforced furan composite (BFC), an eco-friendly material, was manufactured to apply the pipe insulation cover that requires environment-friendly and heat/flame retardant performance. An optimization study of post-curing conditions of BFC was conducted, and experiments and analysis were performed on mechanical strength, heat/flame retardant properties, and affinity properties. Finally, as a result of the study BFC material is proved to be a good candidate to apply pipe insulation cover.
