The document describes two models of an air permeability tester - a digital model and an analog model. Both models measure the air resistance, air permeability, maximum pore size, mean pore size, and micron rating of filtration media. The digital model provides direct digital readings on screen while the analog model uses a u-tube water manometer. Both clamp the sample between annular grips and create a vacuum to draw air through the sample, then measure the volume of air using calibrated flow meters. The tester is used to characterize important properties of filtration media.

2. Air permeability called of a fabric to allow passage of air through it under the effect of a different in
pressure across its two faces. It is defined as the volume of air passing through a defined area under a
specified pressure difference over a known period of time. It is a very important property for fabrics which
are used under conditions where it is necessary to know precisely the amount of air passing through it.

TECHNICAL DATA
IS 11056 - 1984 Method for Determination of air permeability of Fabrics
DIN 53887 Testing of Textiles - Determination of the Air Permeability of fabric
RELATED STANDARD
The test specimen is held between two annular ring shaped grips. The grips are lined with rubber gaskets to
reduce flow of air through the edges. The two grips can be brought in contact with each other with the help of a
hand operated screw arrangement. The test area can be altered by placing adapter discs of different openings
in the grips.
The vacuum needed to draw air through the exposed area of the test specimen is created with the help of a
vacuum pump supplied with the equipment. The volume of air passing through the test area is measured with
the help of a set of rota meters. A digital pressure indicator is provided to indicate the difference in pressure
between the two faces of the test specimen.
The equipment is assembled over a sheet metal panel and is finished in grey hammertone stoving painting and
bright chrome / zinc plating to give it a corrosion resistance finish.
