General:
The method evaluates the corrosivity of heat transfer fluids (HTFs) toward common system metals under controlled laboratory conditions.
It is essentially the heat transfer fluid equivalent of ASTM D1384 (which applies to engine coolants).
This test method covers a simple beaker-type procedure for evaluating the effects of heat transfer fluids (HTF) on metal specimens under controlled laboratory conditions. Fluids tested under this method are specifically designed for heating and air conditioning (HVAC) systems.
Test:
The test determines how well a heat transfer fluid protects metals used in thermal fluid systems, such as:
Carbon steel
Copper
Brass
Stainless steel
Aluminum (if applicable to the system)
Precision:
Repeatability, reproducibility and bias are not established as the method is designed as a comparative corrosion screening test.
