標準簡介
This Standard specifies test methods for determining the refractive index of plastics, namely; Method A : a refractometric method for measuring the refractive index of moulded parts, cast or extruded sheet or film, by means of a refractometer; Method B : an immersion method (making use of the Becke line phenomenon) for determining the refractive index of powdered or granulated transparent materials by means of a microscope.
