Title
TEST METHOD FOR SURFACE HARDNESS OF FPD POLARIZING FILM

Semiconductor Equipment and Materials International

Publication Date:
Jul 1, 2007

Scope:

This specification defines the measurement method of surface hardness of a polarizing film and its materials for FPD applications.

NOTICE: This standard does not purport to address safety issues, if any, associated with its use. It is the responsibility of the users of this standard to establish appropriate safety and health practices and determine the applicability of regulatory or other limitations prior to use.

Purpose

This specification defines the procedural guideline for measuring the surface hardness of a polarizing film and its materials for FPD. These procedures are applicable to manufacturing, quality control, and development work.

This specification clarifies the differences when evaluating a polarizing film and its materials, using ISO15184:1998 "Paint and Vanishes – Determination of Film Hardness by Pencil Test," the specification defined for determining the hardness of coating films. It specifically clarifies the load in the test method and evaluation items in the evaluation method.
