- Abstract
- This report describes a spray ignition flammability test procedure which was developed and designed to be used as an alternative to the spray ignition test used by the Mine Safety and Health Administration (MSHA) to qualify hydraulic fluids for use in underground coal mines. The test procedure allows for quantitative measurement of heat and energy developed by fluids which may ignite in the test and provides for rank ordering of fluids according to their flammability. The testing program included currently used fluids such as invert emulsions, synthetics, and water glycols. Studies showed that the water glycol fluids were the only fluid type to resist ignition by spray testing. All other fluid types were ignited and in some cases produced considerable flaming.
