1.1 本试验方法涵盖航空涡轮燃料中过氧化氢含量的测定。本试验方法也可适用于测定任何水不溶性有机液体，特别是柴油、汽油和煤油中的过氧化氢含量。 1.2 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 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咨询并建立适当的安全、健康和环境实践，并确定监管限制的适用性。 有关特定警告声明，请参阅 6.3 – 6.5 , 附件A1 和 附件A2 . 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 本试验方法和试验方法 D3703 测量航空燃料中相同的过氧化物种类（主要是过氧化氢）。 4. 2. 过氧化氢数的大小表示存在的氧化成分的数量。燃油变质会导致过氧化氢和其他含氧化合物的形成。过氧化氢数测量将氧化碘化钾的化合物。 4.3 由于氢过氧化物对燃料系统中的某些弹性体产生不利影响，因此测定燃料的氢过氧化物数具有重要意义。

1.1 The test method covers the determination of the hydroperoxide content of aviation turbine fuels. The test method may also be applicable to the determination of the hydroperoxide content of any water-insoluble, organic fluid, particularly diesel fuels, gasolines, and kerosines. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This standard does not purport to address all the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to consult and establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific warning statements, see 6.3 – 6.5 , Annex A1 , and Annex A2 . 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 ====== 4.1 This test method and Test Method D3703 measure the same peroxide species (primarily hydroperoxides) in aviation fuels. 4.2 The magnitude of the hydroperoxide number is an indication of the quantity of oxidizing constituents present. Deterioration of fuel results in the formation of hydroperoxides and other oxygen-carrying compounds. The hydroperoxide number measures those compounds that will oxidize potassium iodide. 4.3 The determination of the hydroperoxide number of fuels is significant because of the adverse effect of hydroperoxides upon certain elastomers in the fuel systems.
