See the questions first

Two from the bank, answered.

Real items, with the answer marked and the reason written out — the same format as all 240.

Core (Universal)

Section 608 of the Clean Air Act primarily regulates which activity?

  1. AThe price technicians may charge customers
  2. BThe design of home thermostats
  3. CHow refrigerant is handled in serviceCorrect
  4. DThe electrical wiring of condensing units

Why: Section 608 of the Clean Air Act establishes the national program for managing ozone-depleting and substitute refrigerants during the service, maintenance, repair, and disposal of appliances. It does not set thermostat designs, service prices, or wiring rules. The regulations that carry out Section 608 are found in 40 CFR Part 82, Subpart F.Clean Air Act §608

Recovery & Recycling

Which term means simply removing refrigerant from an appliance and storing it in an external container without cleaning or testing it?

  1. AReclamation
  2. BRetrofitting
  3. CRecycling
  4. DRecoveryCorrect

Why: Recovery is removing refrigerant from an appliance and putting it into a container in any condition, with no processing. Recycling cleans it for reuse, and reclamation restores it to new-product purity verified against AHRI 700. Knowing these three definitions is one of the most tested exam topics.40 CFR §82.152

The exam itself

EPA Section 608 Technician Certification, by the numbers.

Questions50–100 questionsThe count is fixed by Appendix D to Subpart F and does not vary by certifying organization — but it depends on which certification you sit. Each section is 25 questions. Type I, Type II and Type III are each the Core section plus one technical section; Universal is the Core section plus all three technical sections.
TimeNot published by US EPANo time limit exists in § 82.161 or in Appendix D to Subpart F, and EPA publishes none. Any time allowance is set by the certifying organization giving the test.
SectionsCore (Universal) · Regulations & Safety · Type I — Small Appliances · Type II — High-Pressure · Type III — Low-Pressure · Recovery & Recycling
Passing score70%This is the one figure the regulation itself fixes, so it does not vary by certifying organization. It applies to the closed-book, proctored test for every type. A Type I certification taken in the mail-in, open-book format requires 84 percent instead.
