Abstract
This study was conducted to determine methods for improving sensitivity standards for smoke detectors. The smoke detection theory was theoretically reviewed, and local and international indoor air quality and sensitivity test standards were compared and analyzed. The results showed that the uniformity of the specimen, nonreflection of spatial characteristics, differences in experimental methods, and simple test conditions were limitations for local sensitivity test standards. Small-scale sensitivity tests performed according to Korean standards and Go/No-go tests (actual-scale sensitivity test) according to UL268 were conducted to improve the limitations of the Korean sensitivity test standards. The analysis results showed that carbon monoxide and particulate matter 10.0 could be used as factors when configuring test conditions. The equation between obscuration and selected factors was derived. The enactment of standards related to actual-scale sensitivity tests in Korea and the revision of test conditions by applying the equation of selected factors were proposed to improve sensitivity tests.
