ASTM D5598 Standard Test Method for Evaluating Unleaded Automotive Spark-Ignition Engine Fuel for Electronic Port Fuel Injector Fouling
ASTM D5598对汽车无铅火花点火发动机油进行电子口燃油喷口结污评定的标准试验方法
1. Scope
1.1 This test method covers a vehicle test procedure to evaluate the tendency of an unleaded spark-ignition engine fuel to foul electronic port fuel injectors (PFI).
1.2 The test method is applicable to unleaded spark-ignition engine fuels which may contain antioxidants, corrosion inhibitors, metal deactivators, dyes, deposit control additives, and oxygenates.
1.3 The values stated in SI units are to be regarded as the standard. The values in parentheses are provided for information only.
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. Specific precautionary statements are given throughout this test method. Note 1
If there is any doubt as to the latest edition of Test Method D 5598, contact ASTM Headquarters. Other properties of significance to spark-ignition engine fuel are described in Specification D 4814.
