This European Standard specifies the general procedure for determining:a)The inward leakage of facepieces; orb) inward leakage of respiratory protective devices (RPD), which isThe total inward leakage excluding any filter penetration; orc) total inward leakage of respiratory protective devices.Device preparation, selection of test subjects, test procedure andThe method of calculation of leakage are included. Two methods are described, one using an aerosol (sodium chloride aerosol) and one using a gas (sulfur hexafluoride)
