This standard establishes comprehensive technical specifications for the specific product of coated boxboard. It stipulates the requirements for the performance, appearance, and other aspects of such paperboard, and details the corresponding inspection methods and judgment rules, providing a unified basis for the production, inspection, and sale of the product. The standard explicitly states that it applies to products primarily made with bleached wood pulp for the top layer and unbleached sulfate wood pulp for the bottom layer, which are single-side coated. During the testing process, it is necessary to use corresponding conventional paper testing instruments based on the various test methods described, such as specialized equipment for determining indicators like basis weight, brightness, smoothness, surface absorption weight, and ring crush strength.
