Breaking News!
Clark Testing is now offering Coolant testing in the form of ASTM D7820 – Engine Coolant Corrosion Protection Under Accelerated Thermal and Oxidizing Conditions Using a Rotating Pressure Vessel.

This is an accelerated test method to assess engine coolant performance under high temperature oxidizing test conditions of new, used or recycled engine coolants. The test may also serve as a screening tool to determine the oxidation stability of the coolant in question.
