ASTM D – 05()e2 Standard Test Method for Film Hardness by Pencil Test

It should be recognized that the results obtained may asm between different laboratories when different pencils as well as panels are used. The hardness number is the same as the number of the pencil with one step lower hardness than the pencil that scratches the coating — in other words, the number of the hardest pencil that will not rupture or scratch the coating is the scratch hardness.

This compressive state is much stronger than unstressed glass and can also be induced chemically by ion exchange on the surface.

There is significant competition to produce the thinnest, toughest glass for smartphones and tablets. Originally approved in K Standard supply includes: These results show that the polymers obtained from castor oil exhibited significantly improved modulus, strength and T g over those of soybean oil-based copolymers.
