Abstract
A method of monitoring the fire resistance of hydraulic fluids involves measuring a property of the hydraulic fluid that changes as the hydraulic fluid is used; relating the measurement to the fire resistance of the hydraulic fluid; and if necessary, taking remedial action in order to improve the fire resistance of the hydraulic fluid. A suitable property is the molecular weight of polymer anti-mist additives such as polymethyl methacrylate and the fire resistance may be improved by adding to the hydraulic fluid, a concentrate of the polymer in a suitable solvent when the measured molecular weight falls below an acceptable value.
