    1. Scope

    1.1 This test method covers a procedure for measuring the index of refraction of transparent organic plastic materials.

    1.2 A refractometer method is presented. This procedure will satisfactorily cover the range of refractive indices found for such materials. Refractive index measurements require optically homogeneous specimens of uniform refractive index.

    Note 1--This test method and ISO 489 are technically equivalent.

    1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
