Rubber and plastics hoses and tubing, and their assemblies - Determination of permeability to gas

PUBLISH DATE 2024
ISO 4080:2024

This document specifies three methods to determine the permeability to gas by measuring the volume of gas diffusing through a rubber or plastics hose or length of tubing used for gas applications in a specified time.

  • MethodΒ 1 is for determining the permeability of the complete hose wall or length of tubing wall, excluding end fittings, to the test gas.
  • MethodΒ 2 is for determining the permeability at the hose and fitting interface to the test gas.
  • MethodΒ 3 is for precisely determining the permeability of the complete hose or length of tubing, including end fittings.
