GB/T 40167-2021 "Paper and board — Accelerated ageing (100℃)" is applicable to various printing and writing papers, including coated and filled papers. It specifies an accelerated ageing method in which specimens are placed in airtight glass tubes and aged for a certain period under the condition of 100℃. By comparing the changes in folding endurance and tearing strength of the specimens before and after ageing, the stability of the paper is evaluated, and the specimen handling, ageing conditions, and testing procedures are standardized.
