Modern barriers require more sensitive and accurate test methods. Does E96 stand up to the test?

In this white paper, we address this and much more... going in-depth to discover which test will produce the most accurate results in the most efficient way.

ASTM has approved two test methods to track water vapor transmission from materials: ASTM E96 – Water Vapor Transmission of Materials Using Gravimetric Method (adopted in 1941), and ASTM 1249 – Water Vapor Transmission Rate Through Plastic Film Sheeting Using a Modulated Infrared Sensor (adopted in 1990). This white paper explores these methods to determine which provides better water vapor transmission rate (WVTR) test results to meet today’s packaging needs.
