Inspection Validating the specifications, value and safety of your raw materials, products and assets. Formally confirming that your products and services meet all astm f1249 external and internal standards.

A pressure modulated sensor measures moisture transmitted through the material tested. By producing actionable results in less time, F accelerates product and packaging development, and time to market is similarly reduced. Global Reach Intertek is the industry leader with over 43, astm f1249 in g1249, locations in over countries.

It provides for the determination of asrm water vapor transmission rate Astm f12492 the permeance of the film to water vapor, and 3 for homogeneous materials, water vapor permeability coefficient. F can accurately differentiate barrier attributes of materials and packaging below the sensitivity limits of E Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to astm f1249 wide range of industries around the world.

Send us a request Wilton UK: F provides more precise and repeatable WVTR testing data compared to E96, and 1f249 that information in less time. Referenced Documents purchase separately The astm f1249 listed below are referenced within the subject standard but are not provided as part of the standard.


Testing Evaluating astm f1249 your products and services meet and exceed quality, safety, sustainability and performance standards.

Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.

Water Vapor Transmission Rate (WVTR) ASTM F

F astm f1249 operator-dependent variables for more accurate test results, and enables more informed packaging decisions. Validating the specifications, value and safety of astm f1249 raw materials, products and assets.

It is essential to accurately test the barrier property, also called as water sstm transmission rate WVTR. Certification Formally confirming that your products and services meet all trusted external and internal standards.

ASTM F1249

The method is applicable to sheets and films up to 3 mm 0. Key factors to understand material permeation include thickness of the material and aetm factors such as relative humidity and temperature. astm f1249

The inverse relationship of WVTR to thickness and the direct relationship of Astm f1249 asfm the partial pressure differential of water astm f1249 may not always apply.

Test results from E96 method are also highly operator dependent. The lowest detection limit is limited by the balance, usually only measures WVTR above 0.

ASTM E96 test method is astm f1249 known as gravimetric or cup test. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.


For modern high barrier materials, this method is not sensitive enough to measure the results, or efficiently obtain results in a reasonable time period. F allows companies of all sizes to accomplish more astm f1249 fewer labor resources and provides better, more precise results.

For moisture sensitive products, such as crackers, dry milk astm f1249, prescription medicines, atm. Assurance Testing Inspection Certification. Testing repeatability is of great importance.

E96 is astm f1249 labor intensive and generally provides poor in-lab repeatability and reproducibility between astm f1249. Send us a request Need help or have a question? This method is suitable to test modern flexible barrier films and sheets consisting of single and multilayer natural or synthetic polymers and foils. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
