This standard practice provides methods for evaluating the chemical resistance of Printing inks and Coatings on flexible Encasement materials. Encasement materials may come into contact with a variety of chemicals such as water, alcohol and acids during use, and the methods described in the standard are used to ensure that these Printing and Coatings do not degrade or dissolve as a result of chemical contact. The practice includes four test methods (Methods A through D), which increase in test severity step by step, from incidental to continuous exposure situations. Users should choose the appropriate method based on the type of chemical exposure expected and the need for abrasion resistance. The standard does not cover specific acceptability criteria, which need to be jointly determined by users and producers based on actual application.
