ASTM F396-00(2009)

This practice can be used to evaluate various properties of one-time noncorrectable ribbons on a comparative basis. These properties include write, flake-off, heat stability, bleed-through, offset master erasability, reproduction, unintentional transfer, and general quality, that is, splices, skips, and holes in coating, offset to back of ribbon, and transfer to fingers.

This practice is suitable for comparative service evaluation and research and development. This practice may not be practical for manufacturing control because of time required to run some of the tests.

1.1 This practice provides information and techniques for evaluating several performance qualities of one-time noncorrectable typewriter ribbons on a comparative basis for general office use, but not for specialized applications such as optical character recognition (OCR), data terminals, etc.

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 whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
