標(biāo)準(zhǔn)簡(jiǎn)介

Defines two 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.
