EPA Section 608 CFC Certification Exam Overview
The EPA Section 608 certification is required under the Clean Air Act for any technician who purchases or handles refrigerants used in stationary refrigeration and air-conditioning equipment. The exam is administered by EPA-approved certifying organizations and is divided into four categories: Type I (small appliances), Type II (high-pressure systems), Type III (low-pressure systems), and Universal (all three types combined).
Each type-specific section contains 25 questions. A passing score of 84% (21 out of 25) is required for each section. The Universal certificate requires passing all three type-specific sections. There is no time limit, but most candidates finish within 1 to 2 hours.
The certification covers chlorofluorocarbons (CFCs) such as R-11 and R-12, hydrochlorofluorocarbons (HCFCs) such as R-22, and hydrofluorocarbons (HFCs) such as R-134a and R-410A, as well as their environmental impact and safe handling requirements.
Key CFC Certification Knowledge Areas
The EPA Section 608 exam tests your understanding of refrigerant chemistry, environmental law, and safe handling procedures. You must know the ozone depletion potential of common refrigerants — R-12 has an ODP of 1.0 and is now fully phased out under the Montreal Protocol, while R-22 (HCFC) has been phased out of new equipment production since 2010 and virgin supply restrictions apply since 2020.
Venting prohibitions are a major exam topic. Under Section 608, intentional venting of any CFC, HCFC, or HFC refrigerant is illegal. Recovery equipment manufactured after November 15, 1993 must meet EPA efficiency standards. Technicians must use certified recovery/recycling equipment and follow proper procedures before opening any system or disposing of appliances.
Type I questions focus on small appliances (under 5 lbs of refrigerant, factory-sealed systems). Type II covers high-pressure systems such as residential and commercial air conditioners using R-22 or R-410A. Type III covers low-pressure centrifugal chillers using R-11, R-113, or R-123. Knowing which rules apply to each type is essential for passing.
- ✓Memorize ODP and GWP values for R-11, R-12, R-22, R-123, R-134a, and R-410A
- ✓Understand Montreal Protocol phase-out timelines for CFCs and HCFCs
- ✓Know EPA's three categories of venting prohibition exceptions (de minimis, mixtures)
- ✓Study recovery efficiency requirements for high- and low-pressure equipment
- ✓Learn proper refrigerant cylinder handling, storage, and DOT transport rules
- ✓Understand leak inspection frequency rules based on charge size and system type
- ✓Know the EPA reportable release threshold and required repair timelines
- ✓Review recordkeeping requirements: purchase records, recovery logs, disposal forms
- ✓Practice Type I appliance recovery techniques: system-dependent and self-contained
- ✓Study low-pressure system procedures: deep evacuation, standing vacuum test, nitrogen purge
How to Use This Practice Test PDF
Print the PDF and complete each section separately — Type I, Type II, and Type III — as you would in the actual exam. Time yourself to 25 minutes per section. After scoring, focus your review on any topic where you missed more than 4 questions, since a passing score requires getting at least 21 out of 25 correct.
Use the EPA Section 608 study guide published by your certifying organization alongside this practice test. For free reference material, the EPA publishes Refrigerant Recovery and Recycling — A Technician's Guide and related fact sheets at epa.gov/section608. Repeat the practice test until you consistently pass all three sections before scheduling your certification exam.
