This test method is used to compare the relative erasability of similar ribbons having approximately the same amount (degree) of ink (inking) transfer capability. It is suitable for compiling rankings for comparative testing against a control ribbon for service evaluation and quality control (research).

1. Scope

1.1 This test method covers the determination of the erasability of inked ribbons.

1.2 Results are expressed in visual ranking order or in comparison to a control.

1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.4 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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
