The SB detection sensitivity of our test at an impact pressure of 21.3 kPa was carried out by visual inspection of leaked SB on the back surface of the sample and on the absorption paper. The sample fabric was considered as having failed the splash test if SB leakage was detected (upper two rows of Table 2 ). For woven sample 3, the fail rate was 5/5 based on the absorption paper and 0/5 by visual inspection; for samples 4 and 5, the rates were 5/5 and 3/5, respectively. For non-woven sample 10, the fail rate was 2/5 based on the absorption paper and 1/5 by visual inspection; for sample 11, the rates were 4/5 and 3/5, respectively. Therefore, leakage could be detected with greater sensitivity using absorption paper than by visual inspection (i.e., the ISO 22609 test). The testing apparatus consisted of a test booth equipped with a splash gun, sample holder, and a splash pressure control unit. Samples were placed on a sheet of absorption paper in the holder, which had a diameter of 8 cm. The distance between the splash gun and sample holder was 30 cm. A 2-ml volume of SB was ejected by the splash gun at the sample.
