ASTM International has devised a new test for measuring oxygen transmission rate through plastic packaging for food, pharmaceuticals and other products.

The 'F3136 Test Method for Oxygen Gas Transmission Rate through Plastic Film and Sheeting Using a Dynamic Accumulation Method', is applicable for film, sheeting, laminates, coextrusions and coated or uncoated papers or fabrics.

The new standard is utilized for package material and design evaluation, quality control and assurance, research and development, and competitive product and film analysis.

ASTM member and Harbor Associates packaging consultant Nick Winters said: "The development of the new standard was important because it validates commercial development of low cost, durable and simple-to-use instrumentation for oxygen permeability testing."

Oxygen transmission rate, which is a crucial property of packaging, aids in extension and controlling of the shelf life of products.

F3136 will be useful for the manufacturers of packaging films and those engaged in commercial testing labs.

Earlier this month, ASTM came up with a standard for conducting strength test for fiber-reinforced plastic (FRP) used in pipelines, cooling towers and other construction projects.

The standard, 'E2954 Test Method for Axial Compression Test of Reinforced Plastic and Polymer Matrix Composite Vertical Members', helps consumers determine strength of square, round and rectangular tubing, I-shapes, channels and other shapes.
