BS EN ISO 4080:2024

This standard BS EN ISO 4080:2024 Rubber and plastics hoses and tubing, and their assemblies. Determination of permeability to gas is classified in these ICS categories:

• 23.040.70 Hoses and hose assemblies

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.
