DIN 53122-2

Introducing DIN 53122-2 - Industrial Physics

DIN 53122-2 is a global DIN international standard that’s used to measure the water vapor transmission rate of plastic films, elastomer films, paper, board and other sheet materials using an electrolysis method. 

WVTR is the amount of water vapor transmitted through a unit area of a test specimen per unit of time under specified conditions. 

This DIN standard serves to determine water vapor transmission rate (WVTR) - also known as the density of moisture flow rate (DMFR) - of sheet materials using the Keidel electrolytic hygrometer.  

The DIN 53122-2 test method can be applied to single-layer or laminated plastic films, plastics-coated papers and other sheet materials. It’s best suited for determining a density of moisture flow rate ranging from 0.01 to 5 g(m2.d). 

Why is WVTR testing to DIN 53122-2 standards valuable?  

It goes without saying that you don’t want water vapor to get through your packaging films and barriers. It’s obvious why you wouldn’t want this in the food sector – nobody likes soggy potato chips! But it’s also a vital and more demanding consideration for our customers who work with highly sensitive electronics in the automotive or aerospace sectors, for example. 

In order to measure water vapor permeability through a material, you’ll need to know the water vapor transmission rate (WVTR) or moisture vapor transmission rate (MVTR). Simply put, this permeation rate calculation shows you the mass of water vapor that is transmitted through a measured area in a specific unit of time under specified conditions of temperature and humidity.
