Abstract

Amended at the Law of indoor air quality management open a court according to the test method and excess standard of the fluid building material were changed. It used the paint and the putty in the fluid building material from this research and comparison of amended and original method it led and in about change direction of amended standard with change of the emission rate who is caused by in the amended test method and excess standard it examined. The reduction emission rate about 45% decreases in the change of test period of the paint, there was not an effect of the emission rate whom it follows in change of dry time. Also change of the emission rate whom it follows in change of application quantity the product which above $5\;mg/m^2h$ has the high emission rate the change of the emission rate is big but there was not change of the emission rate from the products of that others. The putty the emission rate about 61% decreases in case in the change of test period, there was not an effect of the emission rate whom it follows at dry time. The emission rate about 164% increased with increase of application quantity. It tried to compare two test methods, it compared in the paint and putty all current test method it was relaxed the possibility of knowing the thing there was a standard.

이 연구에서는 2008년에 개정된 "다중이용시설 등의 실내 공기 질 관리법"의 시행규칙 중에서 페인트와 퍼티의 시험방법과 개정된 시험방법을 비교하고 변경된 관리기준의 변화 방향에 대해서 알아보았다. 페인트의 경우 개정된 시험방법은 시험기간의 변경으로 인하여 원래 시험방법에 의한 방출강도 보다 약 45% 감소하였으며, 건조시간의 변화에 따른 방출강도의 영향은 없었다. 또한 도포량의 변화에 따른 방출강도의 변화는 $5\;mg/m^2h$ 이상의 높은 방출 강도를 가지는 제품은 방출강도의 변화가 크나 그 이외의 제품들에서는 방출강도의 변화가 없었다. 퍼티의 경우 개정된 시험방법은 시험기간의 변경으로 원래 시험방법에 의한 방출강도 보다 평균 61% 감소하였고, 건조시간의 변화에 따른 방출강도의 영향은 없었다. 그러나 퍼티의 도포량의 변화로 인하여 원 시험방법에 의한 방출강도보다 약 164% 증가 하였다. 개정된 시험방법에 따른 변경된 TVOCs의 관리기준은 페인트와 퍼티 모두 원래 시험방법에 의한 과거의 관리기준 보다 각각 1.8배 및 5.8배 완화된 것으로 나타났다.
