Application Summary AI generated
GB/T 2913-2026 specifies the method for measuring the whiteness of plastic materials using a photoelectric reflectometer or spectrophotometer. It is applied in quality control and product development within the plastics industry to evaluate the optical appearance of raw resins, masterbatches, and finished plastic products such as films, sheets, and molded parts. The standard ensures consistent whiteness assessment for applications where color uniformity is critical, including packaging, consumer goods, and construction materials.
