BT-13 Navistar Stability Heating Test
Sliding or slow moving, highly loaded systems such as industrial machinery and heavy duty gear boxes may become overheated due to friction and other conditions. Lubricants, cutting fluids and gear oils contain extreme pressure additives to protect metallic surfaces from wear. To maintain this protection, the fluids must be stable at high temperatures. This test determines the stability of lubricating fluids at elevated temperatures.
The fluid is heated to 149°C for 100 hours. The resulting percent pentane insolubles (ASTM D893), change in viscosity (ASTM D445) and evaporation loss are reported.
