In the ASTM D1384 corrosion test, our heat transfer media (in addition to prototype and competitor products) are subjected to extreme conditions for 336 hours at 88°C. This procedure lets us examine corrosion inhibition and oxidation stability properties. Metal coupons — modified to meet the respective requirements — are used as test samples. These metal samples normally consist of copper, brass, various aluminium alloys, iron, steels, and hard and soft solders of various compositions.
Conclusions can be drawn about the quality of the heat transfer medium by examining visual changes of the test samples, the weight differential after testing, and changes in the pH value of the test medium. TYFOCOR® quality is plain to see.
