1 Scope This part of GB/T 12704 specifies the method to determine water-vapor transmission of fabrics with water method. This part includes two methods: Method A “upright cup method” and Method B “inverted cup method”. This part is applicable to various sheet fabrics with thickness less than 10mm. Thereinto, Method B is only applicable to testing of waterproofing permeable fabric. 2 Normative References The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of GB/T 12704. For dated references, subsequent amendments (excluding corrections), or revisions, of any of these publications do not apply to this part of GB/T 12704.
