GB/T 459-2002 "Determination of Dimensional Stability of Paper and Board" specifies the method for determining the dimensional stability of paper and board, applicable to various types of paper and board. The test involves soaking the specimen in water until saturation and measuring its dimensional changes, or equilibrating it under standard temperature and humidity conditions and determining the rate of dimensional change after humidification or drying. The standard clarifies specimen handling, measurement accuracy, and result calculation methods, reflecting the dimensional stability of paper under varying humidity conditions.
