SUPERSEDED (see Active link, below)
ASTM F92
1. Scope
1.1 This practice covers the determination of the usable image producing life of an inked fabric typewriter ribbon or an inked fabric printer ribbon expressed as the number of impressions obtainable from a given unit.
1.2 This practice is not applicable to one-time typewriter ribbons such as carbon ribbons.
1.3 This practice is suitable for narrow printer ribbons with a width of 2 in. (50.8 mm) or less.
1.4 The values stated in inch-pound units are to be regarded as the standard. The SI units given in parentheses are for information only.
1.5 This standard does not purport to address all of the safety problems, 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.
