US: New ASTM standard for testing water vapor transmission

Understanding water transmission rate is a key component for the shelf life of many products. The standards organization American Society for Testing and Materials (ASTM) is developing a new standard to test the transmission rate of water vapor into packaging materials.
The proposed standard (WK49124, Test Method for Water Vapor Transmission Rate through Packages Using a Modulated Infrared Sensor) is based on another ASTM standard (F1249) that measures water vapor through plastic film and sheeting with a pressure modulated infrared detector. This detector lends itself well to testing whole packages, including bottles with closures and sealed pouches (News Release ASTM, 13 May 2015).
