  • Page 77: Appendix A Filter Saturation Test

    Test for saturation by organic gases (limited usage) • For our purpose, Esco will be using the propan-2-ol challenge and burning sulphur test method. SECTION B: PROPAN-2-OL CHALLENGE TEST The filter, when challenged continuously at 800 ppm +/- 50 ppm of propan-2-ol, shall maintain the concentration of propan-2-ol in the exhaust stream at below 40 ppm throughout the period of evaporation of 1 liter of propan-2-ol and below 400 ppm throughout the period of evaporation of 2 liter of propan-2-ol.

Determine the air volume flow rate through the fume cupboard and record the value as F /min. 2. Pour about 100 ml of propan-2-ol into a preweighted, stoppered, conical flask containing a few anti-bump granules.
