EN ISO 12572: Water Vapor Permeability of Construction Products

 

The EN ISO 12572 standard defines methods for determining the water vapor permeability of construction products. This standard is crucial for evaluating the capacity of materials to regulate moisture, which has a significant impact on indoor climate and the longevity of buildings. By complying with this standard, companies can ensure their products meet the required standards for moisture management.

Main Testing Methods in EN ISO 12572

The EN ISO 12572 standard describes several testing methods, including:

High Vacuum Method:

This method uses a high vacuum to measure the water vapor permeability of materials, providing highly precise results. It is often applied in specialized laboratories where a highly controlled testing environment is required.

Water Vapor Diffusion Resistance:

This method measures the resistance that the material provides to water vapor penetration. It is ideal for evaluating moisture regulation and is commonly used in the testing of insulation materials.

Comparative Analysis:

This method allows for the direct comparison of water vapor permeability between different materials. It is particularly useful for selecting the most suitable materials for specific applications.
