Sheet materials - Determination of water vapour transmission rate (WVTR) - Gravimetric (dish) method

ISO 2528:2017 specifies a method for the determination of the water vapour transmission rate (often erroneously called "permeability") of sheet materials. This method is not generally recommended for use if the transmission rate is expected to be less than 1 g/m2 per day or for materials thicker than 3 mm. In such cases the method specified in ISO 9932 is preferred. The method cannot be applied to film materials that are damaged by hot wax or that shrink to an appreciable extent under the test conditions used. For some purposes it may be necessary to determine the transmission rate of creased material; a procedure for this is given in Annex A.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
