SAE Compatibility Fluid /ISO Refereace Fluid

Part No: RM 66-07

Quantity:1 Quart(32 FL 0Z)0.946L

CHEMICAL STABILITY—Mix 30mL of fluid with 30mL of SAE Compatibility Fluid described in Appendix B (RM-66-). Determine the equilibrium reflux boiling point of this fluid mixture by use of the test apparatus specified in 5.1, applying heat to the flask at such a rate that the fluid is refluxing in 10 min ± 2 min at a rate in excess of 1 drop/s. The reflux rate shall not exceed 5 drop/s. Record the maximum fluid temperature observed during the first minute after the fluid begins refluxing at a rate in excess of 1 drop/s. Over the next 15 min ± 1 min, adjust and maintain the rate of reflux to 1 to 2 drops/s. Maintain a timed and constant equilibrium reflux rate of 1 to 2 drops/s for an additional 2 min; record the average value of four temperature readings taken at 30s intervals as the final equilibrium reflux boiling point. Chemical reversion is evidenced by the decrease in temperature between the maximum fluid temperature recorded and the final equilibrium reflux boiling point.
