纸和纸板 CIE白度的测定，D65/10°(室外日光)
Application Summary AI generated
This standard specifies the method for measuring the CIE whiteness of paper and board under D65 illumination and a 10° observer angle, simulating outdoor daylight conditions. It is applied in the paper manufacturing and quality control industry to evaluate the optical brightness of white or near-white paper products, such as printing paper, packaging board, and office paper, ensuring consistency in visual appearance for end-use applications. The test is critical for production lines and laboratory testing to meet customer specifications for whiteness under natural daylight viewing conditions.
