GB/T 21332-2008 Rigid cellular plastics—Determination of water vapour transmission properties
Abstract
This standard specifies the methods for determining the water vapor permeability, water vapor transmission rate, water vapor transmission coefficient, and water vapor diffusion resistance index of rigid foam plastics. This standard applies to rigid foam plastics with a thickness of more than 10 mm. They can be complete materials or foam materials with self-adhering or adhered surface layers.
