IP 354 - Acidity in Aviation Turbine Fuel

We perform testing by IP 354 to measure trace amounts of acid in jet fuel, which can impair the fuel’s water separation characteristics and cause corrosion. Some acids can be present in aviation turbine fuels due either to the acid treatment during the refining process or to naturally occurring organic acids. Significant acid contamination is unlikely because of the many check tests made during the refining process. However, trace amounts of acid are undesirable because it can impair the water separation characteristics of the aviation turbine fuel and cause the fuel to corrode metals. Acidity by IP 354 determines the acidity in aviation turbine fuel in the range from 0.000 to 0.100 mg KOH/g.

We also perform acidity and acid number testing by ASTM D1613ASTM D3242ASTM D3339ASTM D664ASTM D7795ASTM D847ASTM D974IP 139IP 177ISO 6618ISO 6619, and SAE ARP5088. These different test methods use different instruments or procedures or are used for certain sample types.
