1.1 本试验方法仅包括在加速氧化条件下测定成品汽油的稳定性。( 警告- 本试验方法 2. 不用于测定汽油成分的稳定性，尤其是含有高百分比低沸点不饱和化合物的汽油成分，因为这些成分可能会在装置内引起爆炸性条件。但是，由于某些样品的性质未知，压力容器组件应包括一个安全爆破盘，以保护操作员。） 注1: 通过测量潜在胶质来测量汽油的氧化稳定性，请参阅试验方法 D873 ，或IP测试方法 138 注2: 精度数据是使用仅来自烃源且不含氧化物的汽油开发的。 1.2 公认的国际单位制压力单位为千帕（kPa），温度单位为摄氏度。 1.3 警告 -许多监管机构已将汞指定为一种危险物质，可导致严重的医疗问题。汞或其蒸汽已被证明对健康有害，并对材料具有腐蚀性。处理汞和含汞产品时要小心。有关更多信息，请参阅适用的产品安全数据表（SDS）。当地或国家法律禁止销售汞或含汞产品，或两者兼有。用户必须确定其所在地销售的合法性。 1.4 本标准并非旨在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、健康和环境实践，并确定监管限制的适用性。 1.5 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====== 5.1 诱导期可用于指示车用汽油在储存过程中形成胶质的趋势。然而，应该认识到，在不同的储存条件和不同的汽油下，其与储存中树胶形成的相关性可能会显著不同。

1.1 This test method covers the determination of the stability of gasoline in finished form only, under accelerated oxidation conditions. ( Warning— This test method 2 is not intended for determining the stability of gasoline components, particularly those with a high percentage of low boiling unsaturated compounds, as these may cause explosive conditions within the apparatus. However, because of the unknown nature of certain samples, the pressure vessel assembly shall include a safety burst-disc in order to safeguard the operator.) Note 1: For measurement of oxidation stability of gasoline by measurement of potential gum, refer to Test Method D873 , or IP Test Method 138. Note 2: The precision data were developed with gasolines derived from hydrocarbon sources only without oxygenates. 1.2 The accepted SI unit of pressure is the kilo Pascal (kPa), and of temperature is °C. 1.3 WARNING —Mercury has been designated by many regulatory agencies as a hazardous substance that can cause serious medical issues. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Use Caution when handling mercury and mercury-containing products. See the applicable product Safety Data Sheet (SDS) for additional information. The potential exists that selling mercury or mercury-containing products, or both, is prohibited by local or national law. Users must determine legality of sales in their location. 1.4 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. 1.5 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 ====== 5.1 The induction period may be used as an indication of the tendency of motor gasoline to form gum in storage. It should be recognized, however, that its correlation with the formation of gum in storage may vary markedly under different storage conditions and with different gasolines.
