Scope:

This method measures the air permeability in terms of the number of cubic centimetres of air passing through one square centimetre of fabric per second when the differential between the air pressures on opposite sides of the fabric is equal to 12.7 mm of water. It is applicable to all types of fabrics and to a variety of other permeable materials in sheet form.
