ASTM F1782-97(2008)

1.1 This practice covers the determination of the amount of ink deposit, sometimes known as ink content, on inked fabric ribbons.

1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. See 6.1 and 9.4 for specific precautionary statements.
Rationale:

This practice covers the determination of the amount of ink deposit, sometimes known as ink content, on inked fabric ribbons using gravimetric analysis. The amount of ink deposit is determined by analytically weighing a conditioned test specimen. The ink deposit is removed by the use of a suitable solvent(s) in an ultrasonic cleaner. The de-inked fabric sample is conditioned and reweighed. The amount of ink deposit is then calculated. The apparatus which shall be used are the analytical balance and the ultrasonic bath.
