Question 1
A technician is servicing a domestic freezer containing 2.2 pounds of R-
22. Which EPA certification is required?
A. Type I
B. Type II
C. Type III
D. Universal
,ANSWER: A. Type I
EXPLANATION: Small appliances containing 5 pounds or less of
refrigerant that are hermetically sealed at the factory fall under
Type I certification rules.
Question 2
When recovering R-134a from a window AC unit using a passive recovery
system with an inoperative compressor, the technician should:
A. Access only the low side of the system.
B. Access only the high side of the system.
C. Access both the high and low sides of the system.
D. Vent the remaining vapor after 5 minutes.
ANSWER: C. Access both the high and low sides of the system.
EXPLANATION: Accessing both the high and low sides is necessary
when the compressor is dead to optimize refrigerant recovery
efficiency and prevent oil trapping.
Question 3
Which of the following refrigerants used in modern household
refrigerator units is classified as an A3 flammable refrigerant and has a
low GWP?
A. R-12
B. R-22
C. R-134a
D. R-600a
,ANSWER: D. R-600a
EXPLANATION: R-600a (isobutane) is an A3 hydrocarbon refrigerant
used increasingly in small appliances because of its low global
warming impact.
Question 4
What maximum weight of refrigerant defines a "small appliance" under
EPA Section 608 regulations?
A. 2 pounds
B. 5 pounds
C. 15 pounds
D. 50 pounds
ANSWER: B. 5 pounds
EXPLANATION: The EPA strictly defines a small appliance as a product
manufactured, charged, and hermetically sealed in a factory with 5
pounds or less of refrigerant.
Question 5
Which type of recovery equipment captures refrigerant with the
assistance of components within the appliance being serviced?
A. Self-contained recovery equipment
B. System-dependent recovery equipment
C. Active recovery equipment
D. Dual-stage recovery equipment
, ANSWER: B. System-dependent recovery equipment
EXPLANATION: System-dependent (passive) recovery uses the
pressure of the appliance compressor or a vacuum pump paired
with a non-powered recovery bag/tank to remove refrigerant.
Question 6
Technicians who perform open-book, unproctored online Section 608
Type I exams must achieve what passing score?
A. 70%
B. 72%
C. 80%
D. 84%
ANSWER: D. 84%
EXPLANATION: Online open-book exams require a higher passing
score of 84%, whereas proctored, closed-book exams require a
72% passing grade.
Question 7
If a technician passes an unproctored open-book Type I exam, what
limitation applies to their certification?
A. It expires after 2 years.
B. It cannot be used to purchase any HCFC refrigerants.
C. It cannot be upgraded to a Universal certification without retaking Core
in a proctored setting.
