CFC CFC Section 608 Certification Types 2 — Questions and Answers
Question 1: Under Section 608, small appliances (Type I) are distinguished from other system types by having a refrigerant charge of no more than how many pounds?
- 2 pounds
- 5 pounds (Correct answer)
- 10 pounds
- 15 pounds
Correct answer: 5 pounds
Type I small appliances are defined as systems with 5 pounds or less of refrigerant that are fully factory-charged and hermetically sealed.
Question 2: A technician with only Type II certification encounters a large centrifugal chiller using R-11. What must they do?
- Proceed since Type II covers all systems
- Obtain Type III or Universal certification before servicing (Correct answer)
- Obtain a temporary EPA waiver
- Use only Type I recovery equipment
Correct answer: Obtain Type III or Universal certification before servicing
Type II certification only covers high-pressure systems; a technician must hold Type III or Universal certification to legally service low-pressure systems like R-11 chillers.
Question 3: How does EPA Section 608 certification differ from Section 609 certification?
- Section 608 covers mobile AC; Section 609 covers stationary systems
- Section 608 covers stationary refrigeration and AC; Section 609 covers motor vehicle AC (Correct answer)
- They are identical programs with different names
- Section 609 is only for commercial systems
Correct answer: Section 608 covers stationary refrigeration and AC; Section 609 covers motor vehicle AC
Section 608 governs stationary refrigeration and air-conditioning equipment, while Section 609 applies specifically to refrigerant handling in motor vehicle air-conditioning systems.
Question 4: Which certification type is considered the most comprehensive under EPA Section 608?
- Type II
- Type III
- Universal (Correct answer)
- Type I
Correct answer: Universal
Universal certification is the most comprehensive because it qualifies a technician to service all appliance categories covered under Section 608.
Question 5: A technician working on a rooftop commercial packaged unit using R-410A needs which Section 608 certification type at minimum?
- Type I
- Type II (Correct answer)
- Type III
- No certification needed for R-410A
Correct answer: Type II
R-410A is a high-pressure refrigerant, so servicing equipment containing it requires at least Type II certification under Section 608.
Question 6: Under EPA Section 608, which persons are specifically required to hold certification?
- Only technicians who install new equipment
- Technicians who purchase refrigerant or service refrigerant-containing equipment (Correct answer)
- Only HVAC contractors with 5+ employees
- Anyone who owns refrigeration equipment
Correct answer: Technicians who purchase refrigerant or service refrigerant-containing equipment
Section 608 requires certification for any technician who purchases refrigerants or performs service that involves handling or recovering refrigerants from equipment.
