ISO 19013-2:2016规定了内燃机汽油燃料回路中使用的橡胶管和软管的要求。涵盖的汽油燃料包括那些含有氧化物的燃料，如甲醇和已氧化的燃料（“酸性气体”）。此外，ISO 19013的这一部分还可以作为一个分类系统来应用，以使原始设备制造商（OEM）能够详细说明特定应用的“线路调用”测试，这些测试不包括在规定的主要类型中（见附录G中的示例）。在这种情况下，软管或管道不会带有任何显示ISO 19013？2:2016编号的标记，但可能会详细说明OEM自己的识别标记，如其零件图所示。

ISO 19013-2:2016 specifies the requirements for rubber tubing and hoses used in gasoline fuel circuits for internal combustion engines. The gasoline fuels covered include those containing oxygenates such as methanol and fuels that have become oxidized ("sour gas"). In addition, this part of ISO 19013 can also be applied as a classification system to enable original equipment manufacturers (OEMs) to detail a "line call-out" of tests for specific applications where these are not covered by the main types specified (see example in Annex G). In this case, the hose or tubing would not carry any marking showing the number of ISO 19013？2:2016, but may detail the OEM's own identification markings as shown on their part drawings.
