국문 초록

본 연구에서는 Chung’s equations 1, 2와 3을 확장하고 화재 시 연기위험성 등급 평가를 표준화하기 위해 연기성능지수-V와 연기성장지수-V를 계산하였다. 이를 위하여 6 종류의 목재를 선별하여 ISO 5660-1의 규격에 의한 콘칼로리미터(cone calorimeter)법으로 시험하였다. 또한 총괄적으로 Chung’s equation-VI에 따라 연기위험성지수-VI에 의한 연기위험성을 등급화 하였다. 그 결과, 연기위험성지수-VI는 굴참나무(0.03) ≈ 밤나무(0.04) ≈ 느티나무(0.08)

영문 초록

In this study, smoke performance index-V and smoke growth index-V were calculated to expand Chung s equations 1,2, and 3 and to standardize smoke hazard rating evaluation in case of fire. For this purpose, six types of wood were selectedand measured by the cone calorimeter method according to ISO 5660-1. Also, overall, smoke risk was graded by smokerisk index-VI according to Chung s equation-VI. As a results, smoke hazard index-VI was found in the order of oyster oak(0.03) ≈ chestnut (0.04) ≈ zelkova (0.08) < PMMA (1.00) < pitch pine (3.13) < spruce (10.08) < lauan (11.65). Therefore,it was predicted that oyster oak, chestnut, and zelkova had the lowest smoke risk, and lauan had the highest. However,the average concentration of carbon monoxide in the specimen is 53-142 ppm, which is higher than the OSHA limit (PEL),it is concerned that it will harm health.
