ASTM F3299-18

Introducing ASTM F3299-18 – Industrial Physics

ASTM F3299-18 is a global ASTM test method that guides water vapor transmission rate testing of plastic sheeting and film using a coulometric electrolytic detection sensor. 

The water vapor transmission rate (WVTR) is an important property of packaging materials and can be directly related to shelf life and packaged product stability. The purpose of this ASTM test method is to obtain reliable values for manufacturers and users of plastic sheeting and film.   

To carry out this type of permeability test in a repeatable and reliable manner you will need to invest in a suitable water vapor transmission rate tester. 

Why is water vapor permeation testing important?

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. 

What types of plastic sheeting testing does ASTM F3299-18 cover?

ASTM F3299-18 water vapor transmission rate testing is applicable to sheets and films made from single or multilayer synthetic or natural polymers and foils. This also includes coated materials.  

What can your WVTR testing results be used for?

The reliable data you obtain from following the ASTM F3299-18 approach can be used as a referee method of water vapor transmission rate testing. That’s as long as the purchaser and seller have agreed on sampling procedures, standardization procedures, test conditions, and acceptance criteria.
