DIN 533803-3

Introducing DIN 533803-3 - Industrial Physics  

DIN 533803-3 is a global DIN international standard to follow when you need to determine the gas transmission rate of plastic films using the volumetric 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. 

DIN 533803-3 gas transmission rate testing key definitions  

Here are some of the common terms you’ll encounter when you are gas transmission rate testing to DIN 533803-3 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 DIN 533803-3 gas transmission testing 

Over the decades we’ve learnt a thing or two about gas transmission rate testing. This includes monitoring the oxygen transmission rate of polyethylene and measuring the transmission rate of packaging films. We like to share this knowledge where we can!

Need DIN 533803-3 GTR testing support? Get in touch  

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

For example, we wrote this blog on the types of oxygen analyzers, their uses and functions. Then there’s this piece detailing how to protect your reputation with oxygen permeation testing, or this one that investigates the barriers to permeation testing, what can be measured…and why?
