F provides more precise and repeatable WVTR testing data compared to E96, and provides that information in less time.
The method is applicable to sheets and films up to 3 mm 0. Due to the limitation of the sensitivity. Link to Active This link will always route to the current Active version r1249 the standard. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
Water Vapor Transmission Rate Scope: Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Packaging Applications – Industrial Determine water vapor transmission rate of flexible f12499 materials used in packaging or industrial applications. Need help or have a question? It provides for the determination of 1 water vapor transmission rate WVTR2 the permeance of the film to water vapor, and 3 for homogeneous materials, water vapor permeability coefficient.
Water Vapor Transmission Rate (WVTR) ASTM F1249
F eliminates operator-dependent variables for more accurate test results, and enables more informed asttm decisions. At a selected temperature and humidity, a barrier film is sealed between a wet chamber and dry chamber. A pressure modulated sensor measures moisture transmitted through the material tested. Formally confirming that your products and services meet all trusted external and internal standards. Product packaging plays an important role in protecting product quality for the duration of its desired v1249 life and providing packaged product stability.
F can accurately differentiate barrier attributes of materials and packaging below the sensitivity limits of E Packaging Applications – Healthcare 4. Send us a request Need help or have a question? The lowest detection limit could be as low as 0. Test results from E96 method are also highly operator dependent.
Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Key factors to understand material permeation include thickness of the material and environmental factors such as relative humidity and temperature.
E96 is highly labor intensive and generally provides poor in-lab repeatability and reproducibility between labs. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of asfm standard. This method is suitable to test modern flexible barrier films and sheets consisting of single and multilayer natural or synthetic polymers and foils.

Note 1 — Values for water vapor permeance and water vapor permeability must be used with caution.
F allows companies of all sizes to accomplish more with fewer labor resources and provides better, more precise results.
Send us a request Wilton UK: For moisture sensitive products, such as crackers, dry milk powers, prescription medicines, etc. Assurance Testing Inspection Certification. F has many clear advantages over E96, including precision, repeatability, accuracy and sensitivity. Inspection Validating the specifications, value and safety of your raw materials, products and assets.
