GB/T 40166-2021
Paper and board—Accelerated ageing (exposure to nitrogen dioxide)

GB/T 40166-2021 "Paper and board — Accelerated ageing (in nitrogen dioxide)" is applicable to paper and board. It specifies the test method for accelerated ageing of samples in a nitrogen dioxide environment, clarifying parameter requirements such as nitrogen dioxide concentration, ageing temperature, and time. The standard defines the procedures for sample preparation, ageing equipment, test operations, and performance testing after ageing, aiming to evaluate the ageing stability of paper under specific gas environments.
