ASTM D6422-99 PDF

Scope: 1.1 This test method covers the ability of gasoline-alcohol blends to retain water in solution or in a stable suspension at the lowest temperature to which they are likely to be stored or exposed in use. 1.2 This test method is intended to measure the temperature at which a gasoline-alcohol blend separates into two distinct phases in accordance with the criteria defined in this test method. Samples that form a haze are considered not to have phase separated. 1.3 This test method is applicable to gasoline-alcohol blends for use as fuels in spark-ignition engines that contain saturated C1 to C4 alcohols only. The test method does not apply to fuels that contain an alcohol as the primary component, such as M85 or Ed85, or to gasoline-ether blends. 1.4 The values stated in SI units are the standard, except when other units are specified by federal regulation. Values given in parenthesis are provided for informational purposes. 1.5 This standard may involve hazardous materials, operations, and equipment. 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 the standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
