GB/T 42267-2022 specifies the determination method of compression permanent deformation of flexible porous polymer materials under humid conditions. The standard specifies the scope of application, specifies the principle and process of measuring residual deformation after applying compressive force to materials and unloading in a specific humid environment, standardizes instrumentation and equipment, sample preparation, test steps and result calculation, and makes requirements for key parameters such as Humidity, temperature and compression conditions, providing a unified standard for scientifically evaluating the performance of such materials in humid environments.
