Significance and Use
This practice is intended to provide a means of rapid evaluation of comparative image quality relative to carbon paper, carbonless paper, inked ribbons, and similar image-producing products.
1.1 This practice covers standardized procedures utilizing the electric or electronic typewriter as an imaging device for measuring the performance properties of carbonless paper, carbon paper, inked ribbon, and similar image producing products.
Note 1—Electric and electronic typewriters covered by this practice have a full-character type element. Examples of such elements are type bar, ball, thimble, and daisy wheel.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 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.
