The results of a qualitative fitting test for half-mask respirators utilizing a sodium saccharin aerosol were compared to the results of a quantitative fitting test utilizing an oil mist aerosol. For a respirator-wearer combination having a fit factor less than 10, as determined by the quantitative test, the point estimate of the probability of that combination not being rejected by the saccharin qualitative test was found to be 0.00 with 95% confidence that this statistic is not expected to exceed 0.05. For a respirator-wearer combination having a fit factor less than 100, the point estimate of the probability of that combination not being rejected by the qualitative test was found to be 0.03 with 95% confidence that this statistic is not expected to exceed 0.08. The effects of temperature and relative humidity on the size distribution of the saccharin aerosol were also investigated and found to be slight.
将利用糖精钠气雾剂对半面罩呼吸器进行定性贴合测试的结果，与利用油雾气溶胶进行定量贴合测试的结果进行了比较。对于通过定量测试确定贴合系数小于10的呼吸器佩戴者组合，发现该组合不被糖精定性测试拒绝的概率的点估计值为0.00，且有95%的置信度认为该统计量预计不会超过0.05。对于贴合系数小于100的呼吸器佩戴者组合，发现该组合不被定性测试拒绝的概率的点估计值为0.03，且有95%的置信度认为该统计量预计不会超过0.08。还研究了温度和相对湿度对糖精钠气雾剂粒径分布的影响，发现影响较小。
