EPA 608 Type 2 Practice Test 2025 (High Pressure Appliances)

Last Updated on January 18, 2025

EPA 608 Type 2 Practice Test 2025 (High or Very High-Pressure Appliances) Questions Answers. You can free prepare for the EPA 608 Certification Exam on our website.

High-pressure or extremely high-pressure systems are covered in the Type II exam, but not vehicle air conditioning or small appliances. Although the recovery procedures and standards are also part of this exam, the focus is more on leak detection.

In the actual test, there will be 25 questions with the following subject matter:

  1. Before charging a system, the correct ways to look for leaks and how to conduct a leak test.
  2. Annual leak rate for systems holding more than 50 pounds of refrigerant in commercial and industrial refrigeration
  3. Techniques and needs for recovery
  4. The best way to manage emissions while the system is being recovered and reduce cross-contamination
  5. Recovery requirements for these systems’ disposal, maintenance, and leaks.
  6. The determination of a high-pressure system’s essential parts
  7. How to do the pressure/temperature test and where the refrigerant is situated in the system
