5.1 Test Method—The Coordinating Research Council sponsored testing to develop this test method to evaluate a fuel's tendency to form intake valve deposits. 5.1.1 State and Federal Legislative and Regulatory Action—Regulatory action by California Air Resources Board (CARB)5.1.2 Relevance of Results—The operating conditions and design of the engine used in this test method are not representative of all engines. These factors shall be considered when interpreting test results. 5.2 Test Validity: 5.2.1 Procedural Compliance—The test results are not considered valid unless the test is completed in compliance with all requirements of this test method. Deviations from the parameter limits presented in Sections 12 – 14 will result in an invalid test. Apply engineering judgment during conduct of the test method when assessing any anomalies to ensure validity of the test results. 5.2.2 Engine Compliance—A test is not considered valid unless the test engine meets the quality control inspection requirements as described in Sections 10 and 12. |
