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).

Sample EPA 608 Type 1 Practice Test Questions

Test your knowledge with these three questions from our EPA 608 Type 1 practice test. Review the explanations carefully — each EPA 608 Type 1 practice test question highlights the reasoning behind the correct answer.

Q: When recovering refrigerant from a small appliance with an operating compressor, what is the minimum recovery efficiency required?

  • A. 80%
  • B. 85%
  • C. 90% ✓
  • D. 95%

Explanation: This EPA 608 Type 1 practice test question tests a core rule: EPA regulations require 90% recovery efficiency when the small appliance compressor is operational. When the compressor is non-operational, the minimum drops to 80%. If neither 80% nor 90% can be achieved, the system must be evacuated to 4 inches of Hg vacuum.

Q: Which of the following is considered a "small appliance" under EPA Section 608?

  • A. A 10-ton rooftop AC unit
  • B. A split-system heat pump
  • C. A household refrigerator ✓
  • D. A centrifugal chiller

Explanation: This EPA 608 Type 1 practice test question covers definitions. A small appliance is equipment that is manufactured, charged, and hermetically sealed in a factory with 5 lbs or less of refrigerant. Household refrigerators fit this definition. Rooftop units and split systems are Type II (high-pressure), and centrifugal chillers are Type III (low-pressure).

Q: Before disposing of a small appliance, a technician discovers it has a known refrigerant leak and the compressor will not run. What is the required recovery procedure?

  • A. Recover 90% of the charge
  • B. Recover 80% of the charge
  • C. Evacuate to 4 inches Hg vacuum
  • D. Evacuate to 0 psig ✓

Explanation: This EPA 608 Type 1 practice test scenario is frequently tested. When a small appliance is known to be leaking and must be disposed of, the technician is required to evacuate the system to 0 psig (atmospheric pressure) before disposal. This is the minimum requirement when dealing with leaking systems being sent for scrap.

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.
