About EPA 608 Testing
The Federal Government of the United States requires all individuals who open a system or container holding a controlled refrigerant to be certified. Persons who work on stationary equipment or use refrigerant designed for these systems can become certified by passing a proctored Section 608 examination. Candidates for this test can be certified in any of three equipment categories plus Universal.
Type I: A Type I technician primarily works on small appliances such as domestic refrigerators, window air conditioners, PTACs and vending machines.

Type II: A Type II technician primarily works on equipment using a high pressure refrigerant such as HCFC-22. The equipment includes residential air conditioners and heat pumps, supermarket refrigeration and process refrigeration.
Type III: A Type III technician primarily works on equipment using a low pressure refrigerant such as HCFC-123 or CFC-11. These units are primarily chillers.

Universal: Any candidate passing all three of these EPA types is certified as Universal.
To pass any EPA type, a candidate must pass the Core section of the test plus one of the technician types listed above. Once Core is passed, it need not be taken again and it may be used for additional EPA types. The test is divided into four sections: Core, Type I, Type II and Type III. Each test section has 25 multiple choice questions drawn from a bank of test questions. Questions regarding equipment regulations, safety, shipping and identifying refrigerants appear in every test section, so it is important to know these well. Multiple versions of the test are offered at the same time, each with different questions. A passing score of 70%, or 18 out of 25 correct, is required in order to be certified. Each section is graded independently, so a technician could pass Core, Type I and Type III and fail Type II. In this case the technician would be certified as a Type I & Type III technician. Core must be passed to receive any certification. All sections must be passed in order to achieve Universal Technician status.
A technician may choose to take Core plus any combination of Type I, Type II or Type III. It is not required to take all four sections on the examination, however, much of the content from section to section relates to Core content, so once the Core content is mastered, reviewing for the other sections is much easier.
