1.1 This test method covers the determination of the volume of liquefied petroleum gas diffusing through the wall of a hose during a specified period of time. 1.2 The values stated in SI units are to be regarded as standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. A specific precautionary statement is given in the warning in Section 5 . 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 2.1 Rubber hose has an inherent characteristic of permitting diffusion of a gas through the hose structure. This test method quantitatively measures the loss of liquefied petroleum gas.
