Glass substrate can be undecorated, decorated, uncoated, coated, annealed or strengthened, flat or patterned. One or more of the surfaces of glass may have a surface with ink, coatings, frit, patterns, a low-e type coating etc.
1.3This test method is a qualitative test which covers manual and semi-automatic mechanical pummel testing and visual rating of tested specimens.
