This European Standard specifies a method to assess the resistance to oxidation of a phosphate ester fluid under accelerated oxidizing conditions, together with the corrosive effect on copper and steel during ageing. The means of assessment is the change in acidity of the fluid plus absorbent water and the change in mass of test pieces of copper and steel. The precision of the test method applies to changes in acid number up to 3,0 mg KOH/g and changes in mass of up to 3 mg per test piece.
NOTE Accelerated oxidation of fire-resistant fluids based on phosphate esters is characterized by the formation of acid constituents.
