ISO 2528: Determination of Water Vapor Permeability of Materials

 

The ISO 2528 standard specifies a method for determining the water vapor permeability of materials. This standard is crucial for assessing how materials allow moisture to pass through, which is significant for numerous applications in the packaging and construction industries. Compliance with the ISO 2528 standard ensures that materials effectively act as barriers against water vapor, thus maintaining the quality and durability of products.

Key Testing Methods in ISO 2528

The ISO 2528 standard includes various methods for accurately measuring water vapor permeability:

Gravimetric Method

This method determines permeability by measuring the weight of water that passes through the material over a defined period. It allows precise determination of the permeability rate under controlled conditions.

Capillary Method

This method investigates the material’s ability to transport water through capillarity. It is particularly useful for porous materials and helps to understand the interaction between water and the material.

 

Application Areas of the ISO 2528 Standard

The ISO 2528 standard is important in various fields, including:
