1.1 本试验方法涵盖了一种加速实验室和现场程序，用于在水存在的情况下，在汽油和掺有10%硫酸的汽油等样品上测定铁的腐蚀 % 乙醇，E10（规格 D4814 ); 汽油混合物成分（丁烷除外）；柴油和生物柴油B5，4-D级除外（规范 D975 ); 生物柴油B6至B20（规格 D7467 ); 柴油混合成分，如轻循环油；1号燃油、2号燃油（规格 D396页 ); 航空涡轮燃料（规范 D1655 ). 1.2 以国际单位制表示的数值应视为标准。 1.2.1 例外情况- 括号中的值仅供参考。 1.3 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。 1.4 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====== 5.1 一般来说，只要存在水与产品/材料混合的可能性（涵盖在 1.1 )通过该试验方法获得的结果将表明铁部件的预期腐蚀程度。 5.2 测试还确定产品/材料的防锈性能（涵盖在 1.1 )为测试产品在管道运输之前或运输过程中可能经过的各个阶段做准备。 5.3 测试结果还旨在表明是否向产品/材料中添加了铁缓蚀剂的剂量水平和类型（涵盖在 1.1 )足以实现受影响资产（如储罐、工艺管线和运输系统）的预期保护。

1.1 This test method covers an accelerated laboratory and field procedure for the determination of corrosion of iron, in the presence of water, on samples such as gasoline and gasoline blended with 10 % ethanol, E10 (Specification D4814 ); gasoline-blend components (except butane); diesel fuel and biodiesel B5, except Grade No. 4-D (Specification D975 ); biodiesel B6 to B20 (Specification D7467 ); diesel-blend component such as light cycle-oil; No. 1 fuel oil, No. 2 fuel oil (Specification D396 ); aviation turbine fuel (Specification D1655 ). 1.2 The values stated in SI units are to be regarded as the standard. 1.2.1 Exception— Values in parentheses are for information only. 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. 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 ====== 5.1 In general, wherever the possibility exists of water getting mixed with products/material (covered under 1.1 ) the results obtained by this test method will indicate the degree to which corrosion of iron components can be expected. 5.2 Test also determines the antirust properties of products/material (covered under 1.1 ) in preparation for the various stages through which the tested product may pass prior to or during its transport through a pipeline. 5.3 Test results are also meant to show whether or not the dosage levels and type of iron corrosion inhibitor added to a product/material (covered under 1.1 ) is sufficient for achieving the desired protection of affected assets such as storage tanks, process lines, and shipment systems.
