The NATE-recognized EPA 608 Core exam (often paired with NATE certification exams) covers foundational knowledge on ozone depletion, Clean Air Act regulations, Montreal Protocol, refrigerant chemistry (ODP/GWP), the "Three Rs" (Recover, Recycle, Reclaim), leak detection, safe handling/shipping, and general safety protocols. It consists of 25 multiple-choice questions.
Key Topics Covered in the EPA 608 Core Syllabus: Environmental Impact: Ozone depletion, effects of CFCs, HCFCs, HFCs, and HFOs on the atmosphere, and global warming potential (GWP).

Refrigerant Types & Identification: Properties of common refrigerants, refrigerant blends (azeotropic vs. zeotropic), and oil types. Recovery, Recycling, and Reclaiming: Definitions, proper techniques for recovering refrigerant, and safety regulations regarding the "Three Rs". Leak Detection: Methods for detecting leaks in various systems. Safety & Shipping: Safety precautions for handling refrigerants, proper usage of recovery cylinders, and shipping regulations.
