This British Standard gives methods for the determination of:
a) mass per unit length; and
b) mass per unit area
of woven fabrics that have been in the standard atmosphere for testing.
The methods are applicable to woven fabrics (including those of the "stretch" type) made up full width or folded down the middle, and apply to the determination of the fabric mass of complete pieces as well as of sample lengths.
