1.1本试验方法包括评估抑制矿物油（尤其是汽轮机油）在水与油混合时帮助防止含铁零件生锈的能力。本试验方法也用于测试其他油，如液压油和循环油。程序中规定了重于水的液体的测试。 注1-对于合成流体，如磷酸酯类型，塑料支架和烧杯盖应由耐化学性材料制成，如聚四氟乙烯（PTFE）。 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和健康实践，并确定监管限制的适用性。 有关具体的警告声明，请参阅6.4-6.6。 ====意义和用途====== 在许多情况下，例如在蒸汽涡轮机的齿轮中，水可能与润滑剂混合，并且铁质零件可能生锈。 该测试表明，抑制矿物油有助于防止此类生锈。本试验方法也用于测试液压油和循环油，包括比水重的流体。它用于新机油的规格和在用机油的监测。 笔记 3-本试验方法用作试验方法D 3603的基础 . 试验方法D 3603 用于在单独的水平和垂直测试杆表面上测试油，并可以提供更具辨别力的评估。

1.1 This test method covers the evaluation of the ability of inhibited mineral oils, particularly steam-turbine oils, to aid in preventing the rusting of ferrous parts should water become mixed with the oil. This test method is also used for testing other oils, such as hydraulic oils and circulating oils. Provision is made in the procedure for testing heavier-than-water fluids. Note 1—For synthetic fluids, such as phosphate ester types, the plastic holder and beaker cover should be made of a chemically resistant material, such as polytetrafluoroethylene (PTFE). 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. For specific warning statements, see 6.4-6.6. ====== Significance And Use ====== In many instances, such as in the gears of a steam turbine, water can become mixed with the lubricant, and rusting of ferrous parts can occur. This test indicates how well inhibited mineral oils aid in preventing this type of rusting. This test method is also used for testing hydraulic and circulating oils, including heavier-than-water fluids. It is used for specification of new oils and monitoring of in-service oils. Note 3—This test method was used as a basis for Test Method D 3603 . Test Method D 3603 is used to test the oil on separate horizontal and vertical test rod surfaces, and can provide a more discriminating evaluation.
