标准摘要
[中文适用范围]： 本文件基于吸湿法测定建筑制品和建筑材料在热状态下水分蒸气透过性的方法。不同试件的测试条件均被指定了。所描述的一般原则适用于所有吸湿性和非吸湿性建筑制品和材料，包括绝热材料及带有饰面或表皮的整体式制品。附录中提供了适合测试方法的各种细节。对于不同材料类型获得的结果。本方法可用于设计用途、生产控制以及产品说明书的包含目的。 该结果适用于通过不同材料类型的测定方法获得的结果。 [外文原描述]： ISO 12572:2016 specifies a method based on cup tests for determining the water vapour permeance of building products and the water vapour permeability of building materials under isothermal conditions. Different sets of test conditions are specified. The general principles are applicable to all hygroscopic and non-hygroscopic building materials and products, including insulation materials and including those with facings and integral skins. Annexes give details of test methods suitable for different material types. The results obtained by this method are suitable for design purposes, production control and for inclusion in product specifications.
