ASTM C735-04

Standard Test Method for Acid Resistance of Ceramic Decorations on Returnable Beer and Beverage Glass Containers

SIGNIFICANCE AND USE
This test method evaluates the quality and serviceability of ceramic decorations on returnable beer and beverage containers.
This test method is also suitable for specification acceptance. Its significance is that bottles with good acid resistance coatings have longer service life.
SCOPE
1.1 This test method covers qualitative determination of the acid resistance of ceramic decorations on returnable beer and beverage containers, to assure the necessary durability of the decoration.  
1.2 This test provides an indication of performance when and if the decoration is to be exposed to the acid solutions used in reclaiming bottles, and it also covers those instances where the beverages themselves have acidic properties.  
1.3 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.
