ASBC Methods of Analysis
Surface Protective Coatings
This method evaluates the performance characteristics of durable lubricating coatings on glass in two ways: lubricity and coating quality. The first is a measure of the coefficient of friction between coated glass containers, while the second is a measure of the abrasion protection provided by the coating. Permanently coated nonreturnable bottles can be evaluated by the dry and wet rub test procedures.
