Moisture Permeability Cups

Permeability Cups (also known as Perm Cups or Payne Cups) are used to determine the permeability of films to water vapor and other liquids. Materials tested include paint, varnish, thin plastic films, and other types of sheets thin enough to be tightly sealed across the face of the cup. Permeability is expressed as the weight of vaporous material that passes through a specified area and thickness of free film within a specified time interval under controlled conditions.

The Perm Cup is designed to be in complete compliance with ISO 7783 and ASTM D 1653

Perm cups are available in two sizes: 10cm2 and 25cm
