Plastics. Determination of refractive index1 Scope This International Standard specifies 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. It is applicable not only to isotropic transparent, translucent, coloured or opaque materials but also to anisotropic materials. The method is recommended when great accuracy is

both for testing transport losses of aerosol sampler substrates under prescribed conditions in order to calculate the expanded uncertainty of a measuring procedure according to EN 13205-1:2014

BS EN 17074 provides Product Specific Category Rules for flat glass products (Flat Glass PCR) used in buildings and other construction works to support the assessment of the environmental performance and the development of Environment Product Declarations
