Application
Use for test the light transmittance and haze degree of all transparent and semi-transparent parallel plane samples (plastic plate, sheets etc), and turbidity or clarity of liquid samples (water, drinks etc), used in the industries of plastics, membrane, coatings and paints, printing ink, research institute and so on.
Standards
GB 2410-2008, ASTM D1003-2007, and JISK7105-81.
Principle
The equipment is applied to the evaluation of specific light-transmitting and wide-angle-light-scattering properties of planar sections of materials such as essentially transparent plastic.
Two procedures are provided for the measurement of luminous transmittance and haze. hazemeter and spectrophotomet.Material having a hazevalue greater than 30 % is considered diffusing and should be tested in accordance with Practice E 167.
(The values stated in SI units are to be regarded as the standard.)
