1.2 Although other systems may be available, this practice covers two of the most commonly used instruments; the Clearwave 082 Optical Character Tester and the Macbeth Print Contrast Meter.

1.3 These instruments also have the capability of predicting machine readability of documents. This practice does not address this capability.

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.
