Air Permeability Testing Equipment - UTSTESTER

What is the air permeability test for?

Gas permeability testing is primarily used to evaluate how permeable a material is to gases, including air and specific gases such as water vapor. This type of testing is important for a wide variety of industries and application scenarios including, but not limited to, textiles, apparel, medical supplies, sports equipment, construction materials, electronics, and more. The purpose of breathability testing is to ensure that the material has good gas exchange properties for comfort, safety, longevity, and performance stability.

Specific contents and methods of air permeability testing include:

1. Air flow rate: measure the amount of air passing through a unit area of material per unit time, usually in liters / square meter / second or cubic meters / square meter / second as a unit, reflecting the degree of permeability of the material to the air.
2. Resistance to air permeation: Measures the resistance of a material to air circulation, usually measured in Pascals, reflecting the ability of the material to impede air circulation.
3. Water Vapor Transmission Rate (WVTR): measures the amount of water vapor passing through a unit area of material per unit time, usually in grams/m2/day or grams/m2/hour, reflecting the degree of permeability of the material to water vapor.
4. Moisture Permeability: Relates to the water vapor transmission rate and reflects the material's ability to absorb and remove moisture.

These tests are used not only to evaluate the physical properties of a material, but also to ensure that a product complies with specific industry or safety standards. For example, in the textile industry, breathability is one of the most important indicators for evaluating the comfort of textiles. Especially when designing products such as outdoor sportswear and sports shoes, breathability tests are needed to verify that they can provide good breathability to absorb moisture and sweat and keep them dry. In addition, breathability testing is also used in a variety of fields such as automotive interior materials, construction materials, packaging materials, electronic products, etc., to ensure that the breathability of materials can meet the needs of specific applications.
