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. — Method1 is for determining the permeability of the complete hose wall or length of tubing wall, excluding end fittings, to the test gas. — Method2 is for determining the permeability at the hose and fitting interface to the test gas. — Method3 is for precisely determining the permeability of the complete hose or length of tubing, including end fittings.
