1.1 This test method covers determination of the alkali resistance of ceramic labels (hereafter referred to as ACL (Applied Color Label)) on returnable beverage bottles (hereafter referred to as ware) to ensure the necessary durability of the label. A number of states require the cleaning and sanitizing of this ware by washing in hot alkali solutions. Accelerated tests are needed to ensure that the ACL will withstand the anticipated number of washings and still present an acceptable ware identification and appearance.
