METHOD OF EVALUATING CORROSIVENESS OF JET FUEL

摘要

FIELD: chemistry.SUBSTANCE: method of evaluating corrosiveness of jet fuel comprises determining the decrease in weight of copper-containing material placed in the fuel before and after testing at high temperature. The copper-containing material used is copper foil which is placed in the fuel and held in hermetically sealed cells in the form of metal vessels at temperature of 150±2°C for 4 hours while holding in two steps of 2 hours each and replacing the fuel after the first step. The greater the decrease in the weight of the copper foil before and after test, the more corrosive the jet fuel.EFFECT: high reliability and faster evaluation.1 tbl
