ASE AC 609 EXAM 60 QUESTIONS & CORRECT
ANSWERS LATEST 2025
Ozone Depletion Potential - ANSWER-chemical rating that ranges from 0.01-1.0
and that refers to the amount of ozone depletion caused by a substance
compared to CFC-11 (eg HCFC-22 depletes .034 of the ozone where CFC-11 would
deplete 1.0)
class 1 substance - ANSWER-ozone depleting chemical with an ozone depletion
potential greater than .2 (eg CFCs)
class 2 substance - ANSWER-ozone depleting chemical with an ozone depletion
potential less than .2 (eg HCFCs)
CFCs - ANSWER-Chlorofluorocarbons, eg R-12 (CFC-12)
HCFCs - ANSWER-Hydrochlorofluorocarbons, eg R-22 (HCFC-22)
HFCs - ANSWER-hydrofluorocarbons, eg R-134a (HFC-134a)
HFOs - ANSWER-Hydrofluoroolefins, eg R-1234yf (HFO-1234yf)
mvac - ANSWER-Motor Vehicle Air Conditioner
, MVAC-Like Appliances - ANSWER-an appliance similar enough to an mvac that
one does not need a 608 certification (eg tractors, buses, and construction
equipment. DOES NOT INCLUDE: refrigerated trailers, boats, trains, and aircraft)
ODS - ANSWER-ozone depleting substance
Which component of CFC refrigerant is the cause of ozone depletion? - ANSWER-
Chlorine pg1
The Stratospheric Ozone layer protects us from; - ANSWER-ultraviolet radiation
pg1
The current standard for recovery only equipment is SAE; - ANSWER-J2810 pg3
When checking a cylinder of recycled HFC-134a for non-condensable gasses at
70F, the pressure should not exceed: - ANSWER-76 psig pg10
Section 609 of the Federal Clean Air Act requires that all persons servicing motor
vehicle air conditioning must; - ANSWER-all of the above pg 1
After charging a system using manifold gauges, the refrigerant in the hoses; -
ANSWER-must be recovered pg 5
Recovery cylinders must be; - ANSWER-UL or DOT approved
After initial recovery procedures, the technician should; - ANSWER-. wait 5
minutes to determine if the system returns to a positive pressure
