The 2006 edition (ANSI/ASHRAE Standard 70-2006) represented a significant update. It consolidated previous addenda and refined the test methods for newer refrigerant blends, particularly HFCs (like R-134a, R-404A, and R-410A). For many years, 70-2006 was the active, recognized standard by building codes such as the IMC (International Mechanical Code) and ICC.
