The ventilation resistance test takes the center part of the mask for testing. The gas flow for the test needs to be adjusted to (8±0.2) L/min, the diameter of the sample test area is 25 mm, and the test area of the test sample is A. Measure the pressure difference between the two sides of the mask with a differential pressure meter or equivalent equipment, and calculate the ventilation resistance according to the formula ΔP=M/A.
ΔP-the pressure difference per square centimeter area of the test sample, the unit is Pa per square centimeter (Pa/cm³);
M --The differential pressure value of the test sample in Pa (Pa);
A --Test area of test sample, unit is square centimeter.
