1. Which type of system does EPA Section 608 Type II certification
cover?
a) Small appliances only
b) Low-pressure appliances only
c) High-pressure and very high-pressure appliances
d) All refrigerant-containing equipment
c) High-pressure and very high-pressure appliances
Type II certification applies to high-pressure (over 15 psig) and very
high-pressure appliances, including air conditioning and refrigeration
systems typically found in residential, commercial, and industrial
settings.
2. What is the primary goal of the EPA Section 608 certification?
a) To improve refrigerant efficiency
, b) To prevent ozone depletion by controlling refrigerant emissions
c) To reduce carbon dioxide emissions
d) To increase the lifespan of HVAC equipment
b) To prevent ozone depletion by controlling refrigerant emissions
The EPA 608 program focuses on minimizing the release of ozone-
depleting substances (ODS) like CFCs and HCFCs into the atmosphere.
3. Which refrigerants are commonly handled under Type II
certification?
a) R-22, R-134a, R-404A
b) R-410A only
c) R-12 only
d) All low-pressure refrigerants
a) R-22, R-134a, R-404A
Type II covers high-pressure refrigerants, such as R-22 (HCFC), R-134a
(HFC), and blends like R-404A, which are widely used in commercial
and industrial applications.
4. Which of the following is a characteristic of high-pressure
refrigerants?
, a) Boiling point above 150°F
b) Vapor pressure over 155 psig at 104°F
c) Low global warming potential
d) Only used in small appliances
b) Vapor pressure over 155 psig at 104°F
High-pressure refrigerants have elevated vapor pressures and require
specialized equipment for recovery and service.
5. When performing a refrigerant recovery from a high-pressure
system, which device is required?
a) Standard hand pump
b) Certified recovery machine
c) Vacuum pump only
d) No special device is needed
b) Certified recovery machine
EPA regulations mandate the use of certified recovery/recycling
machines to safely remove refrigerants from Type II systems without
releasing them into the atmosphere.
, 6. What must be done before opening a high-pressure system for
service?
a) Turn off the power and isolate the system
b) Add lubricant to the compressor
c) Increase system pressure to maximum
d) Open all service valves
a) Turn off the power and isolate the system
Safety is critical: electrical isolation prevents shocks, and turning off
the compressor prevents sudden pressure releases during service.
7. How is refrigerant purity typically verified before reuse?
a) By measuring temperature only
b) Using a refrigerant identifier or analyzer
c) By checking the system label
d) By smell and color
b) Using a refrigerant identifier or analyzer
Refrigerant identifiers analyze the composition to prevent
contamination, ensuring that recovered refrigerant meets purity
standards.
