GB/T 14207-2008 "Sandwich structure or core water-absorption test method" standard specifies the specific test method for evaluating the water-absorption energy of sandwich structure or core material. The standard is applicable to all types of sandwich structure or core materials, including but not limited to Spinning & weaving products, hygiene products and other fields. The test method covers the determination of water-absorption energy of materials under different conditions, aiming to provide a standardized evaluation system to ensure that products meet relevant mass requirements. These test results can be used to guide the selection of materials and the design of products, while helping manufacturers and consumers understand and compare the performance of different materials on water-absorption energy.
