1 Scope

This standard specifies the three measurement methods through rubber or plastic hose reinforced hose or a specific time of the gas volume. Method 1. In addition to measuring the entire outer ends of the hose connector hose or reinforced hose to test gas permeability. Permeability of the hose or Enhanced calculate the length of the hose. Method 2. Determination of permeability hose/hose connector contact surfaces. When the hose outer cover layer without needling, gas is usually from the fabric reinforcing layer Exudation cut end, this time using this method. Permeability calculated by the length of the hose. Method 3. Accurate measurement hose or hose assemblies to test gas permeability. Calculated by the surface area of \u200b\u200bthe hose permeability innerliner. This standard applies only to water-insoluble gas. Note 1. Although the results of Tier 1 and Tier 2 are represented by the same unit, but did not use the same piercing and pierced hoses have been obtained no results comparison Necessary because different tests prescribed time, whereby different permeability. Note 2. Method 3 is the preferred method.
