This specification covers circular, fully tempered, high clarity, flat glasses prescribed for use in portlight applications. The glazing quality float glasses are classified into four types according to the type of edge and the texture of each face. All products should conform to the required values for breaking strength, surface and edge compression, clarity, and warpage and quality of finish.
