The TAPPI T 573 standard specifies a method for accelerating the temperature aging of printing and writing paper by means of a dry oven exposure device. The test is designed to simulate the aging process of paper in a high temperature environment in order to assess its long-term Stability and durability. By exposing paper to high temperature conditions in a sealed glass tube, manufacturers can predict how the paper will behave in actual use, ensuring product mass and Reliability. This method is suitable for all types of printing and writing paper, including plain base paper, paper with added internal additives, Spreader paper, printing paper, and variants of Miscellaneous that may occur in normal use.
