Description

Excerpt from A Portable Instrument for Measuring Air Permeability of Fabrics<br/><br/>The portable air permeability apparatus described in this paper can be used to determine the rate of air flow through a great variety of fabrics at pressure drops up to 1 inch of water. By a proper choice of air orifices the uncertainty for an air permeability determination will be less than 42 per cent. This is less than the variation observed between specimens taken from different portions of the same fabric.
