1 ABOUT THIS INSTRUMENTThe Elcometer 5100 Payne Permeability Cup is a simple instrument which is used to determine the vapour
transmission rate of unsupported films of paint, varnish, plastic, paper, etc.
The Payne cup is filled with a suitable liquid or dry desiccant and then the film being tested is clamped andsealed across the open end of the cup.
The assembly is weighed at the start of the test and again at the end. Any difference between the twoweights will be due to water-vapour which has permeated through the film in a given time.
The instrument is simple to use and is available in three sizes to suit the requirements of the film being
tested. The instrument is manufactured from anodised aluminium.
1.1 STANDARDSYour Elcometer 5100 Payne Permeability Cup can be used in accordance with the following National andInternational Standards:
ASTM D1653; ASTM E96; ISO 7783 supersedes NF T30-018.

2 TAKING A MEASUREMENTFigure 1. Elcometer 5100 Payne
Permeability Cups

Take care to avoid damaging your Elcometer 5100 Payne Permeability Cup. Deformation or otherdamage to the cup flange or sealing ring will affect the readings and the instrument may have to bereplaced.
2.1 TEST PROCEDURE
1. Prepare the film to be tested.
3

The coating has to be applieda onto a substrate (eg Leneta RP-1K) which allows the film to beremoved after it has dried. Silicone coated paper is suitable for many types of coating, however theuser of the cup should determine the most suitable substrate for their application.
2. Fill the Payne cup with specified liquid or dry desiccant.
3. Place the film carefully over the top of the cup ensuring that the film covers the flange of the cup.
4. Place the rubber gasket and the sealing ring on the film and secure using the clamps provided.
5. Weigh the assembly and record the result in grams (m1).
6. Leave the cup undisturbed for the period of time stated in the standard conditions.
7. At regular intervals re-weigh the assembly and record the result in grams (m2) until linear.
8. Calculate the water-vapour transmission rate of the film in grams per sq. metre per day (g/(m2.d)):
P = 240 x ∆m / A
Where ∆m = rate of change in mass in mg/h, and A = area in square centimetres of test piece takenfrom the following table:
