This test method covers a procedure to determine a measure of the acid strength of high ethanol content fuels.
1.1This test method covers a procedure to determine a measure of the acid strength of high ethanol content fuels. These include denatured fuel ethanol and ethanol fuel blends. The test method is applicable to denatured fuel ethanol and ethanol fuel blends containing ethanol at 51 % by volume, or more.
1.2Acid strength as measured in this test method is defined as pHe. A pHe value for alcohol solutions is not comparable to pH values of water solutions.
1.2.1The value of pHe measured will depend somewhat on the fuel blend, the stirring rate, and the time the electrode is in the fuel.
1.3The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3.1Hydrogen ion activity in water is expressed as pH and hydrogen ion activity in ethanol is expressed as pHe.
1.4This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
