GB/T 7974-2002 《 Paper,board and pulp-Measurement of brightness-Diff/Geometry》 Related products
The GB/T 7974-2002 standard specifies the method for measuring the luminance (whiteness) of paper, Cardboard and pulp, using the blue light diffuse reflection factor under the simulated D65 Light source to measure the luminance. The standard applies to pulp, paper and Cardboard samples without or containing fluorescent whitening agents to ensure the accuracy of the measurement results.
