자기반응성물질의 성상판정방법에 대한 국내‧외 기준의 비교 연구

Abstract

This study compares the class-5 hazardous substances characteristics assessment method, domestically enforced according to the Safety Control of Dangerous Substances Act, with that of Japanese method, using categorization system of dangerous substances similar to domestic method, and assessment method mentioned in UN RTDG(Recommendations on the Transport of Dangerous Goods) to examine the difference in the assessment method and to reconsider points of improvements for domestic hazardous substances characteristics assessment method. As a result, domestic pressure vessel tests were conducted on three types of orifices of 0.6mm, 1.0mm, and 9.0mm. However, in Japan, test on 0.6mm orifices included in Korea is not included, and the designated quantity was determined to be 10kg and 100kg. In the case of UN RTDG, the diameter of the orifice used ranges from 1.0 mm to 24.0 mm, and the risk of substances was classified according to the experiment results based on the damage on the disk. Therefore, there is a possibility that substances determined as non-risk substances may be defined as dangerous substances by a 0.6mm domestic test, so it is necessary to review international standards more closely and apply them domestically.
