ActiveFibrous raw material, pulp, paper and board—Determination of residue(ash) on ignition at 575℃ and 900℃
造纸原料、纸浆、纸和纸板 灼烧残余物（灰分）的测定（575℃和900℃）
Application Summary AI generated
This standard specifies methods for determining the ash content of fibrous raw materials, pulp, paper, and board by ignition at 575°C and 900°C. It is applied in the paper industry for quality control and raw material analysis, where the lower temperature measures total mineral content and the higher temperature distinguishes between carbonates and other inorganic residues. The standard is used in manufacturing, testing laboratories, and procurement to assess product purity, filler levels, and compliance with material specifications.
