ISO 15105-2

Introducing ISO 15105-2 - Industrial Physics

ISO 15105-2 is a global ISO standard that will determine the gas transmission rate of any plastic material in the form of film, sheeting, laminate, co-extruded material or flexible plastic-coated material. 

There are two different parts to the ISO 15105 gas transmission rate testing standard: 

  • ISO 15105-1: differential-pressure method 
  • ISO 15105-2: equal-pressure method. 

Why is gas transmission rate testing helpful?

Plastic materials form barrier properties for food and other products that may be easily oxidized or mildewed by oxygen and water content. Gas transmission tests are performed to measure the permeation of a particular gas through the barrier materials, helping you to select the right packaging materials to protect your products. 

Gas transmission testing can help to determine whether packages can keep oxygen or other gasses away from sensitive products to avoid the deterioration of their contents. 

ISO 15105-2 transmission rate testing key definitions

Here are some of the common terms you’ll encounter when you are gas transmission rate testing to ISO 15105-2 standards.   

Gas-transmission rate (GTR): the quantity of a given gas passing through a unit of the parallel surfaces of a plastic film in unit time under the conditions of test. 

Gas permeability (coefficient of gas permeability): the volume of gas passing through a plastic material of unit thickness, per unit area and unit time, under unit partial-pressure difference between the two sides of the material.

So, how can Industrial Physics improve your ISO 15105-2 gas transmission rate testing?  

At Industrial Physics we’re proud to supply gas analyzers, gas permeability testers, oxygen analyzers, and moisture analyzers to suit a wide range of industries. 

8700 & 8701 OxySense® Oxygen Permeability Analyser 

The 8700 with fixed platens is ideal for rapid permeation testing of multiple bottles in PET bottle manufacturing and as an invaluable R&D resource in laboratories for development work to test and validate new packages. 

Systech Illinois – AquaSense 7101 Water Vapor Permeation 

Advanced coulometric sensor technology meets the best in user-friendly operation with the AquaSense 7101 water vapor transmission rate tester.  

It’s the ideal choice for measuring the moisture vapor transmission rate (MVTR) of liquids through both current and newly formulated packaging film materials. Which is just what you need for speedy, quality control testing.  

Need gas transmission rate testing solutions? Get in touch

We’ve learnt a thing or two about gas transmission rate testing over the decades. Now Industrial Physics is recognized as a brand that likes to bring new, innovative gas transmission testers and GTR testing equipment to market. 

We like to share our knowledge and we’re here to help you to answer your questions about gas transmission rate testing. Across the knowledgebase section of our website we publish lots of blogs on related subjects.  

You could start with this blog - the Industrial Physics FAQ guide to permeation testing. And then follow-up with this piece which explores why there is a need for measuring the oxygen transmission rate on PET bottle caps.
