Fine ceramics (advanced ceramics, advanced technical ceramics) — Determination of light transmittance of ceramic films with transparent substrate ISO 20508:2003

Publication date:   Nov 28, 2003

Scope

ISO 20508:2003 specifies a test method for determining the visible light transmittance of a transparent coating material, e.g., the transparent electrode for display devices, in which a fine ceramic thin film is coated on to a substrate.
ISO 20508:2003 is not applicable to deliberately coloured, uneven or non-parallel faced test pieces. A translucent medium is not included in this International Standard.
