608 Type II practice questions

Know the scope before you practice.

EPA defines Type II certification for servicing or disposing of high- or very high-pressure appliances, except small appliances and motor vehicle air conditioners (MVACs). EPA-approved certifying organizations administer the certification tests, and the official topic list is the best place to check what areas apply.

The questions below were written for Brassleaf Prep and are based on EPA’s Section 608 Test Topics. They are not copied from an EPA or certifying-organization exam.

Practice questions

1. Question 1 · Type II

   Which equipment category is associated with EPA Section 608 Type II certification?

   1. Small appliances only.
   2. High- or very high-pressure appliances, except small appliances and MVACs.
   3. Low-pressure appliances only.
   4. All equipment, regardless of refrigerant or appliance type.

   Answer: High- or very high-pressure appliances, except small appliances and MVACs.

   EPA defines Type II for servicing or disposing of high- or very high-pressure appliances, except small appliances and motor vehicle air conditioners (MVACs).

2. Question 2 · Type II

   What does EPA list as a Type II practice before charging or recharging a high-pressure appliance?

   1. Leak-test the appliance before charging or recharging.
   2. Vent a small amount of refrigerant to check the odor.
   3. Add a second refrigerant before checking the system.
   4. Skip leak testing when the appliance has a receiver.

   Answer: Leak-test the appliance before charging or recharging.

   EPA’s Type II topic list includes the need to leak-test before charging or recharging high-pressure appliances.

3. Question 3 · Type II

   Which approach can speed the beginning of a recovery process on a Type II appliance?

   1. Recover liquid refrigerant first when the system and equipment instructions allow.
   2. Open the system to air before connecting the recovery machine.
   3. Mix refrigerants in the recovery cylinder.
   4. Use oxygen to raise the appliance pressure.

   Answer: Recover liquid refrigerant first when the system and equipment instructions allow.

   EPA’s Type II recovery topics state that recovering liquid at the beginning can speed the process. The method must still suit the appliance and the recovery equipment instructions.

4. Question 4 · Type II

   After reaching the required recovery vacuum, why wait briefly and observe system pressure?

   1. A pressure rise can indicate refrigerant remains in the appliance or oil.
   2. It confirms that the cylinder label has dried.
   3. A pressure rise proves the system contains nitrogen only.
   4. It replaces the need to check recovery requirements.

   Answer: A pressure rise can indicate refrigerant remains in the appliance or oil.

   EPA lists waiting a few minutes after the required recovery vacuum to see whether pressure rises, which can indicate liquid refrigerant remains in the appliance or oil.

Keep each statement tied to its source.

EPA’s Type II list includes leak detection before charging or recharging, recovery techniques, recovery requirements, refrigeration, and safety. Use EPA’s topic page and the testing organization’s instructions for any regulatory detail that depends on the appliance or service situation.
