✦ Synopsis

THE BUREAU has published a description of the various methods which may be employed for determining ,the permeability of balloon fabrics to hydrogen. The precise and rapid method used at the Bureau of Standards measures the hydrogen penetrating a given area of fabric by means of a gas interferometer. Data are given to show the effect upon the apparent permeability of different experimental conditions such as temperature, pressure, humidi,ty of the gas, etc. A knowledge of the effect of these factors enables one to compare results of tests made under different Conditionsl The test adopted as standard by the Bureau is described.
