ISO 5630-6:2009规定了一种通过暴露于二氧化氮气体加速印刷和书写纸老化的方法，并评估其对机械和光学性能的影响，以预测因暴露于污染空气而发生的长期自然老化的稳定性。适用于所有纤维素基印刷和书写用纸，包括涂布纸和填充纸。

ISO 5630-6:2009 specifies a method for accelerating the ageing of printing and writing papers through exposure to nitrogen dioxide gas and assessing the effect on mechanical and optical properties for the purpose of predicting stability to long-term natural ageing that occurs due to exposure to polluted air. It is applicable to all cellulose-based printing and writing papers, including coated papers and filled papers.
