Knowing the real corrosion potential of fuel ethanol – measuring pHe according to ASTM D6423

Knowing the real corrosion potential of fuel ethanol – measuring pHe according to ASTM D6423

Excessive acidity in alcohol based fuels accelerates engine corrosion. Total Acid Number (TAN) accounts for all titratable acids regardless of their strength and is therefore not suitable to accurately predict the corrosion potential. pHe, on the other hand measures the strength of the acids present in the sample. Therefore, pHe...
