Measurement of the leakage and fit factor of a filtering facepiece by continuous monitoring of pressure pulsations / R.C. Brown, N.P. Vaughan
Sumario: A novel method for measuring the fit factor of filtering facepiece respirators is described. Measurement is made by the continual monitoring of the pressure produced by a volume of air injected into the respirator cavity, and withdrawn so that the added volume varies sinusoidally with time
