ASTM D1434 Standard Test Method for Testing Gas Permeability Characteristics of Plastic Film and Sheeting August 21,2019.

Gas Transmission Rate(GTR),also called gas permeability, is the ability of a barrier material to allow gases (O2, N2, CO2 etc.) to permeate through it in a specific time. Gas permeability may vary with temperature, humidity, pressure and speicmen thickness.



There are many different industries where gas permeation control is very important. Gas sensitive foods, beverages and pharmaceuticals are put in packaging with controlled gas transmission to achieve the safety and shelf life. Also clothing industries, building materials industries both need to control the gas permeation barrier properties.



There are various techniques to measure gas(O2, N2, CO2 etc.),and the popular test method including two type like Coulometry and pressure-difference method, comply to international testing standard ASTM ASTM D3985 ASTM F1927 ASTMD1434.



GBPI has been contribute to barrier properties testing equipment, especially gas/oxygen and water vapor transmission rate tester over 17 years.N530 Gas permeability tester is our GBPI popular star testing equipment for measuring gas transmission rate through barrier material.


Gas Permeability Analyzer ASTM D1434


N530 Gas Permeation Analyzer for the measurement of gas permeability of various films, infusion bags and other packaging materials O2, N2, CO2 and other non-inflammable gas and non-corrosive gases through the barrier properties. It has equipped with three independent testing cells and independent temperature control systems and three testing sensors, can testing three samples at the same time, can testing three different gas. Works with highest precision and testing data accuracy, comply to international testing standard ASTM D1434.
