Water Vapor Permeability (WVP) Testing Services
Water vapor permeability in footwear and leather products is a critical factor in terms of comfort and lifetime. Our laboratory offers water vapor permeability (WVP) testing services in accordance with TS EN ISO 20344 standard. These tests are important to improve the performance of your products and ensure compliance with international standards.
Water Vapor Permeability (WVP) Tests
Definition and Importance of the Test
Water vapor permeability measures how well a material passes water vapor. This property is particularly important for the comfort of footwear. Adequate water vapor permeability reduces foot perspiration and discomfort, thus improving the user experience.
Test Procedure
The water vapor permeability test is performed in accordance with TS EN ISO 20344, TS EN ISO 14268 and TS EN ISO 5402-1 standards. The test sample is conditioned at a specific temperature and humidity and analyzed in a water vapor permeability tester. The test is performed to evaluate the water vapor permeability of the sample and the results are reported in mg/cm²-h.
Safety and Quality Control
In our laboratory, all necessary safety precautions are taken to perform tests safely. Staff work using personal protective equipment such as masks, face shields, goggles and gloves. In addition, water vapor permeability tests are performed in accordance with the “Guide to Analytical Internal Quality Control Practices”, which guarantees the reliability and accuracy of the results.
Reporting of Test Results
Evaluation of Results
Test results are reported as a water vapor permeability (WVP) value, expressed in mg/cm²-h. The report includes information such as the standard used, description of the sample and test conditions. In addition, if any deviations or additional processing was performed, this information is also indicated in the report.
Application Areas
Water vapor permeability tests are of great importance for footwear manufacturers, leather goods manufacturers and quality control laboratories. These tests support the quality control processes of your products, giving you a competitive advantage in the market and increasing consumer confidence.
