标准摘要
[中文适用范围]： 本 SAE 推荐实践提出了可用于模拟真实世界燃料的测试液体的建议。为了限制商业燃料和液体中发现的变异性，需要使用标准化测试液体。商业燃料在制造商、批次、季节和地理位置之间可能存在很大差异。此外，标准化测试液体普遍可用，并将促进材料测试的一致测试结果。因此，本文件：解释商用汽车燃料成分； b.定义材料测试流体的标准化成分； C。定义测试流体的术语； d.描述测试液体的准备；和 e。推荐用于测试燃油系统材料的液体。本文件第 7 节中规定的测试流体成分仅推荐用于评估材料。除非缔约方同意，否则它们不适用于其他活动，例如发动机开发、设计验证或过程验证。本文件附录 B 中列出的市场测试燃料可用于发动机、车辆或部件测试。 [外文原描述]： This SAE Recommended Practice presents recommendations for test fuels and fluids that can be used to simulate real world fuels. The use of standardized test fluids is required in order to limit the variability found in commercial fuels and fluids. Commercial fuels can vary substantially between manufacturers, batches, seasons, and geographic location. Further, standardized test fluids are universally available and will promote consistent test results for materials testing. Therefore, this document:aExplains commercial automotive fuel componentsbDefines standardized components of materials test fluidscDefines a nomenclature for test fluidsdDescribes handling and usage of test fuelseRecommends fluids for testing fuel system materialsThe test fluid compositions specified in Section 7 of this document are recommended solely for evaluating materials. They are not intended for other activities, such as engine development, design verification, or process validation unless agreed upon by the contracting parties. Most marketplace fuels contain additives for such purposes as oxidation stability, intake and combustion chamber deposit control, anti-foaming, electrostatics, octane, corrosion mitigation, etc., applied at a parts per million basis. It is not the intention of this document to include a surrogate for the potential effects of these additives. As far as this committee is aware, current additives do not adversely affect fuel system materials. Those contemplating new or improved additives for future applications could use the basic test fluids or fuels from this document, and specify the fuel is to be unadditized in order to inject such additives and use the resulting mixtures to assess whether these new additives might affect fuel system materials.For the purposes of this document, the term FUEL is used in conjunction with fully blended hydrocarbon or hydrocarbon oxygenate mixtures for use in commercial automotive engines. The term FLUID is applied to mixtures of specific controlled components used to simulate the effects of fuels.Cross Reference:
