    Since the instrumental ratings are affected more than the visual ratings by changes in surface refractive index, non-agreement between visual and instrumental gloss ratings can occur when high gloss specimen surfaces differing in refractive index are compared. The angular dimensions of the receptor eld stop are odf from the receptor lens in a collimated-beam-type instrument, as illustrated in Fig. A study of the effect of geometric conditions on results of gloss tests with special attention to high-gloss panels.

    NOTE 1—The parallel-beam glossmeters possess the better uniformity of principle-ray angle of reection, but the converging-beam glossmeters possess the better uniformity in extent of angular divergence accepted for measurement. Measurements by this test method correlate with visual observations of surface shininess made at roughly the corresponding angles. If the reading is not within Cylindrical Mandrel Bend Tester.

    Specular Gloss – ASTM D523

    Some manufacturers may consider testing and certification an obstacle to overcome to get to market. Others might see it as an important way to reduce risk or liability.

    The ASTM D test method explains the measurement of gloss on non-metallic samples for geometries of 20, 60 and 85 degrees. The ASTM D standard test method is used to measure the gloss of solid plastics and plastic films (opaque and transparent both). There are four separate gloss angles for the different specimens, such as 60° for. ASTM D covers the measurement of the specular gloss of nonmetallic specimens for glossmeter geometries of 60º, 20º, and 85º. The geometry of angles and apertures is chosen so that these procedures may be used as follows: The 60º geometry is used for intercomparing most specimens and for determining when the 20º geometry may be more.
