EPA 608 Core Study Guide
The complete written breakdown of everything covered on the EPA 608 Core exam, organized the way the actual test is structured.
Description
The Core Study Guide covers every topic tested on the EPA Section 608 Core exam: refrigerant regulations, ozone depletion and environmental impact, recovery and recycling requirements, safe handling practices, and technician responsibilities under federal law. Each section is broken into short, plain-language explanations with the exact numbers and thresholds the exam tests on — recovery levels, leak rate percentages, and recordkeeping requirements — so you're not re-reading dense regulatory text to find what matters. Updated for 2026 refrigerant regulation changes. Works alongside any Core, Type I, II, III, or Universal exam purchase.
