Rubber and plastics hoses and hose assemblies - Determination of permeability to gas

ISO 4080:2009 specifies three methods for the determination of the volume of gas diffusing through a rubber or plastics hose or length of tubing in a specified time.Method 1: For determining the permeability of the complete hose or length of tubing, excluding end-fittings, to the test gas. The permeability is calculated with respect to the length of the hose or tubing.Method 2: For determining the permeability at the hose/fitting interface. This method is used when determining the permeability characteristics of hoses with an unpricked cover, when the gas usually issues from the textile reinforcement at the cut ends. The permeability is calculated with respect to the length of the hose.Method 3: For determining precisely the permeability of a hose or hose assembly to the test gas. The permeability is calculated with respect to the surface area of the hose lining.The methods are applicable only to gases which are insoluble in water.

Rubber and plastics hoses and hose assemblies - Determination of permeability to gas

ISO 4080:2009 specifies three methods for the determination of the volume of gas diffusing through a rubber or plastics hose or length of tubing in a specified time.

  • Method 1: For determining the permeability of the complete hose or length of tubing, excluding end-fittings, to the test gas. The permeability is calculated with respect to the length of the hose or tubing.
  • Method 2: For determining the permeability at the hose/fitting interface. This method is used when determining the permeability characteristics of hoses with an unpricked cover, when the gas usually issues from the textile reinforcement at the cut ends. The permeability is calculated with respect to the length of the hose.
  • Method 3: For determining precisely the permeability of a hose or hose assembly to the test gas. The permeability is calculated with respect to the surface area of the hose lining.

The methods are applicable only to gases which are insoluble in water.

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

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