EQUILIBRIUM REFLUX BOILING POINT TESTER OF AUTOMOTIVE HYDRAULIC BRAKE FLUID - BIS 8654

Compliance Standards

Is 8654

Application

To determine the ERBP of hydraulic brake fluid according to ANNEX A of IS 8564 & averaging results.

Summary of test method

60 ml of brake fluid is boiled under specified equilibrium conditions (reflux) at atmospheric pressure in 100 ml flask. The average temperature of the boiling fluid at the end of the reflux period, corrected for variation s in barometric pressure if necessary, is the ERBP.
