By studying various test methods of water vapor transmission rate, Labthink manufactures many water vapor permeability testing instruments based on ASTM E96/GB 1037 (gravimetric method), ISO 15106-2/ASTM F1249 (infrared sensor method), ISO15106-3 (electrolytic sensor method) and ISO15106-1/ASTME398 (humidity sensor method). Labthink has the .Warranty: 1 Years Max Diameter of Workpiece: <500mm Type: Water Vapor Permeability Testing Machine for Leath Accuracy Grade: 0.5 Load Way: Electronic Load Loading Method: Static Load
The water vapour permeability test measures how well fabrics let moisture through. It does this at different temperatures and humidities. It simulates how well fabrics move water vapor. Bodies release it when they sweat. They release it to the outside. Moisture permeability is the quality of water vapor transfer on both sides of the fabric.Lab Asphalt Permeability Testing; Field Permeability Testing of Pavement; Calculating the Coefficient of Permeability; Asphalt permeability has a direct impact on the performance and longevity of pavements. Long-term internal exposure to water and water vapor in the asphalt voids is a significant factor in the premature deterioration of roadways.The test evaluates the water vapor transfer through semi-permeable and permeable samples. The data can be used by manufacturers and designers and is often important in packaging applications. Test Procedure: A cup is filled with distilled water leaving a small gap (0.75" to 0.25") of air space between the specimen and the water.Test Equipment:Air permeability testing machine including an air source, test fixtures, and a flow meter. GB/T 5453 and GB/T 24218.15. . while a humidity control equipment for the water vapor transmission method. BS 3424-16 and BS 6F 100 3.13. Features:Suitable for measuring the air permeability of fabrics.
