The ASTM D2809-2021 standard is used to evaluate the cavitation corrosion and erosion corrosion characteristics of engine chill down fluid on aluminum automotive water pumps. This test method is mainly aimed at testing the corrosion of chill down fluid on water pump materials under actual operating conditions. However, it is worth noting that when testing two-phase chill down agents, the results are not relevant to field tests, so it is not recommended to evaluate the cavitation effect of two-phase chill down agents. The standard provides SI unit reference during the evaluation process and reminds users to comply with relevant safety and environment regulations before use.
