  • Fire has developed from the inter-action of heat at the early state and it is very difficult to estimate the magnitude of the fire. Cone Calorimeter can obtain the important material properties from the exposed part of it. It can be contained that ignition, loss of mass, heat release rate, smoke generation, and gas analysis. The purpose of this study is emphasize on the properties of structural steels in terms of physical, mechanical and that will be important way to build the databases of fire safety.

  • The international standard for FT-IR gas analysis of fire effluents in ISO 5660-1 cone calorimeter has been being developed in ISO TC 92. A comparison of the round-robin test of WD 21397 was conducted with six participating laboratories in 2018. The test specimens were PMMA, rigid PU foam board, and PVC flooring. The measurement quantities were the time-to-ignition, peak heat release rate, total heat release, and effective heat of combustion for a cone calorimeter test and peak gas concentration, gas generation, and gas yield for FT-IR gas analysis. No outliers were identified. For the cone calorimeter quantities, the repeatability and reproducibility were 1.5% and 9.8%, respectively. For FT-IR gas analysis, the repeatability and reproducibility was 12.9% and 27.9%, respectively.

  • 실규모급 화재 실험의 신뢰성 있는 발열량 측정을 위해서 흡입 배관의 직경 1.6 m, 직선길이 26m, 후드 직경 10 m 그리고 흡입용량 $2,000m^3/min$ 이상의 대형 콘 칼로리미터를 구성하여 헵탄의 화재 크기별 연소 실험을 진행하였다. 발열량 측정을 비교 분석하기 위해서 산소 소모 지수법, 질량 소모법, 복사열 그리고 대류열 측정 기법에 따라서 각각의 발열량을 산출하고 크기를 비교하였다. 그 결과 대형 콘 칼로리미터에 의해서 측정한 산소 소모 지수법은 이론 발열량에 해당하는 질량 소모법과 최대 약 2.3 % 정도, 복사열에 의한 발열량 산출법은 12.2 % 정도, 연소면적에 의한 이상적인 발열량과는 최대 30 % 정도, 그리고 대류열만 고려한 경우 약 50 % 정도 차이가 나는 것을 확인하였다.

  • Fire resistance and thermal stability of polypropylene composite systems were investigated by using several halogenated fire-retardants such as decabromodiphenyl oxide (DBDPO) and chlorinated paraffin wax (CPW). The fire resistance of composite systems was thoroughly examined by measuring limited oxygen index (LOI, ASTM D2863, ISO 4589) and characteristic properties of cone calorimetry(ASTM E1354, ISO 5660) heat release rates (HRR), time to ignition (TTI), total heat release (THR), effective heat of combustion (EHC), mass loss rates, etc. Comparing the cone calorimetry experimental results of the halogen flame retardants, DBDPO exhibited twice higher efficiency than CPW in polypropylene systems, and the LOI also showed similar trends to cone calorimetry. The thermo-oxidative stability of the composite systems was increased about 30-5$0^{\circ}C$ in thermogravimetry analysis.Collectively, the combustion, extinction and thermally-stable characteristics of flame retardants were identified in this study.

  • Architectural fabrics are now used in membrane structure with the merits of free shape, lightness and opened up new possibility for the design of new building structures. Recently PVC, PVF, PVDF, PTFE coated fabric for using the membrane structures. However, clear standards for the design and construction is not exist because of the lack of Architectural fabric research. In this paper, Flammable properties of PVDF, PTFE coated fabrics are obtained through the Flammability test using the Cone Calorimeter. Based on these results, identify the fire resistance property of the Architectural fabric.

  • 주거 건축 및 가구산업의 자재로써 합성목재(Wood-Plastic Composites)는 점차 각광받고 있다. 본 연구에서는 합성목재의 연소특성을 살펴보기 위하여 한계산소지수 측정(ASTM D2863) 및 콘칼로리미터 시험(ISO 5660-1)을 실시하였으며 또한 일반목재인 적송(red pine)과 방부 처리를 한 방부목에 대하여도 동일한 시험을 통하여 합성목재와 연소특성을 비교 검토하였다. 한계산소지수 측정결과 합성목재가 적송 및 방부목에 비해 가장 낮게 측정되었다. 콘칼로리미터 시험결과 합성목재의 열방출률값이 가장 빨리 피크치에 도달하였고 점차적으로 감소하였다. 합성목재의 최대 열방출률 값 및 평균 열방출률 값은 적송 및 방부목에 비해 가장 높게 나타났으며 총 방출열량 또한 가장 높게 나타났다.

  • Some major properties such as a heat release rate have been measured experimentally for the validation of fire model and the clarification of fire phenomena as the study is more rigorous recently. Although the reduced-scale experiment also provides the basic data and the physical understanding in fire study, it is not enough to explain real fire problem directly because there is no exact analogy theory between a real fire and the reduced scale model. Therefore, large cone calorimeter have been built and used in a few foreign countries for the measurement of large scale fire. This paper addressed the theoretical background and the description of key features in the design of the facility. It will be a useful guide for implementation of the large scale cone calorimeter in the future.
