WebNov 1, 2024 · Sensitivity test of inflow velocity on contaminant contention. This test was conducted in oder to assess the sensitivity of BSC contention performance to different values on the inflow velocity. The standard for this equipment's certification [23] states that inflow velocity must be in the 0.51 to 0.56 m. s − 1 range. WebThe certification process of a BSC is performed by five tests: downflow velocity test, inflow velocity test, HEPA filter leak test, smoke pattern test and site installation test. The downflow and inflow velocity tests are performed at the same time, because adjusting either the motor/blower or baffle system affects both results.
