Yes. EPA has 2 major standards for refrigerant certification. Certification for Mobile Air Conditioner must be in accordance with EPA Section #609. A separate certification is required for Stationary AC (non-mobile) in accordance with EPA Section #608 (4 separate types exist depending upon the size & type equipment worked on).
