EPA 608 Type I Practice Test

The EPA 608 Type 1 practice test covers small appliances — any refrigeration equipment that contains 5 pounds or less of refrigerant. This includes household refrigerators, window air conditioners, PTAC units, dehumidifiers, drinking water coolers, and vending machines. Our EPA 608 Type 1 practice test focuses on the recovery procedures, equipment requirements, and regulations specific to these small systems. If you service any of these appliances, the EPA 608 Type 1 practice test is your fastest path to certification.

What Does the EPA 608 Type 1 Practice Test Cover?

The Type I section has 25 multiple-choice questions. You need at least 18 correct (70%) to pass. Here are the key topics tested on the EPA 608 Type 1 practice test:

• Small Appliance Definition: The EPA 608 Type 1 practice test defines a small appliance as equipment manufactured, charged, and hermetically sealed in a factory with 5 lbs or less of refrigerant. This includes household refrigerators, freezers, room AC units, PTACs, dehumidifiers, and vending machines.
• Recovery Requirements: The EPA 608 Type 1 practice test emphasizes that technicians must recover 90% of the refrigerant when the compressor is operational, or 80% when the compressor is not operational. If the system is known to be leaking, technicians must evacuate to 0 psig before disposal.
• Pre vs. Post November 15, 1993 Equipment: Recovery equipment manufactured before this date has different efficiency requirements. Post-1993 equipment must be capable of achieving a 4-inch Hg vacuum when the compressor operates and 4-inch Hg vacuum when it does not.
• Self-Contained Recovery Equipment: The EPA 608 Type 1 practice test covers how technicians typically use self-contained recovery devices that capture refrigerant directly without requiring the system compressor. System-dependent equipment uses the appliance's own compressor to aid recovery.
• Refrigerant Identification: The EPA 608 Type 1 practice test includes questions about common small appliance refrigerants: R-12 (older units), R-134a (modern domestic refrigerators), R-22 (window ACs), and R-290 (propane, in newer eco-friendly units).

Key Facts for the EPA 608 Type 1 Practice Test

Keep these critical facts in mind as you prepare with our EPA 608 Type 1 practice test. These are the most frequently tested points on the EPA 608 Type 1 practice test:

• The EPA 608 Type 1 practice test confirms that small appliances do not need to be leak-tested or repaired before disposal — but refrigerant must still be recovered.
• Technicians must have access to a certified recovery device. Using the system compressor (system-dependent recovery) is allowed but not required.
• R-290 (propane) is increasingly used in new small appliances — the EPA 608 Type 1 practice test notes it is flammable (A3 safety classification) and requires special handling precautions.
• The EPA 608 Type 1 practice test covers piercing valves (saddle valves) used to access sealed systems — they should be leak-tested after installation and are considered part of the system.
• The sale restriction exemption, tested on the EPA 608 Type 1 practice test, allows Type I technicians to purchase refrigerant in containers of 20 lbs or less for small appliance service.
