Abstract: Causes for failure silver strip test of jet fuel post to tanker transport were discussed. By analyzing the results of silver strip corrosion test, doctor test, determination of mercaptan sulfur, contents of sulfur and nitrogen in jet fuel post to tanker transport，it was found that the existence of H2S, SO2, SO3, sulfuric acid and sulfuric esters in jet fuel was nearly impossible, the silver strip corrosion should be mainly caused by sulfide corrosion. Simulation test of transporting jet fuel by tanker was carried out and results showed that the dissolving of elementary sulfur from inner tank wall to fuel caused the unqualified silver strip corrosion test.
