ASTM D2457 -Standard Testing Instruments

ASTM D2457 covers the measurement of specular gloss of plastic films and solid plastics using defined reflection angles under controlled lighting conditions. The standard helps manufacturers study surface appearance, shine consistency, and finish quality of plastic products. It is widely applied in industries such as packaging, automobile, consumer goods, electronics, and the polymer industry, where the visual quality of the surface is of importance. The test supports product comparison, process control, and appearance evaluation during manufacturing. Presto Laboratories offers high-accuracy gloss meters designed according to ASTM D2457 requirements for quick and repeatable gloss measurement. The equipment assists industries to keep the surface finish in a consistent manner and also analyze the aesthetic appearance of plastic materials prior to market dispersion.
