ASTM D7244-20 - Standard Test Method for Relative Cure of Energy-Cured Inks and Coatings

1.1 This test method describes the procedure for evaluating the relative cure of printed energy-cured (ultraviolet or electron beam) ink or coating by a mechanical solvent rub test using a motorized Crockmeter.

1.2 This test method is applicable to laboratory and production prints on any flat substrate that is no thicker than 3 mm (0.125 in.), durable enough to withstand the test conditions, and for which a control (reference) sample is available.

1.3 This test method applies to comparisons between energy-cured inks and coatings of the same chemistry and film weight and should not be used to compare different ink or coating chemistries or various applied film weights without first establishing process performance.

1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
