refrigerant had been recovered. MVAC service technicians rely on complete refrigerant recovery to refill MVAC systems according to the motor vehicle manufacturer specification. In light of substandard recovery performance, SAE revised their standards to include performance standards that ensure an improved standard of refrigerant recovery and recharge. SAE replaced standard J with standard J in October 2006. J encompasses all of J, adds standards on recharging of MVAC systems, and adds performance standards to improve equipment refrigerant recovery performance. Specifically, J sets a recharge accuracy standard of 0.5 ounces and
