1.1本试验方法涵盖在规定时间内通过软管壁扩散的液化石油气体积的测定。 1.2以国际单位制表示的数值应视为标准值。 1.3本标准无意解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。第5节的注释中给出了具体的预防说明。 ====意义和用途====== 橡胶软管具有允许气体通过软管结构扩散的固有特性。该试验方法定量测量液化石油气的损失。

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 and health practices and determine the applicability of regulatory limitations prior to use. A specific precautionary statement is given in the note in Section 5. ====== Significance And Use ====== 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.
