EPA 608 CORE ACTUAL CERTIFICATION EXAM
2024 VERSION 1 WITH 200 QUESTIONS AND
CORRECT ANSWERS (100% CORRECT
VERIFIED ANSWERS) WITH RATIONALE
(BRAND NEW!!)
Appliance - ANSWER Any device which contains and uses a
Class I (chlorofluorocarbon; CFC), Class II (hydrofluorocarbon;
HCFC) substance or substitute (e.g. Hydrofluorocarbon: HFC) as
a refrigerant and which is used for household or commercial
purposes, including any air conditioner, motor vehicle air
conditioner, refrigerator, chiller, or freezer. For a system with
multiple circuits, each independent circuit is considered a
separate appliance. EPA interprets this definition to include all air-
conditioning and refrigeration equipment except that designed
and used exclusively for military purposes.
Apprentice - ANSWER Any person who is currently registered as
an apprentice in maintenance, service, repair, or disposal of
appliances with the U.S. Department of Labor's Office of
Apprenticeship (or a State Apprenticeship Council recognized by
the Office of Apprenticeship).
Comfort Cooling - ANSWER A category of air-conditioning
appliances used to provide cooling in order to control heat and/or
humidity in occupied facilities including, but not limited to,
residential, office, and commercial buildings.
Commercial Refrigeration - ANSWER A category of refrigeration
appliances used in the retail food and cold storage warehouse
sectors.
Industrial Process Refrigeration - ANSWER A category of
refrigeration appliances used in industrial materials processing.
,Major Maintenance, Service, or Repair - ANSWER Maintenance,
service, or repair that involves removal of the appliance
compressor, condenser, evaporator, or auxiliary heat exchanger
coil.
Motor Vehicle Air Conditioner (MVAC)- Like Appliance - ANSWER
Mechanical vapor compression, open-drive compressor
appliances used to cool the driver's or passenger's compartment
of an specific to the type of equipment the technician seeks to
work on. Tests must be administered by an EPA-approved
certifying organization. Section 608 Technician Certification
credentials do not expire. Lost cards may be replaced by
contacting the certifying organization.
Opening an Appliance - ANSWER Any service, maintenance, or
repair of an appliance that would release any refrigerant from the
appliance to the atmosphere. Connecting and disconnecting
hoses and gauges to and from the appliance to measure
pressures within the appliance and to add refrigerant to or recover
refrigerant from the appliance are not considered "opening."
Reclaim - ANSWER To reprocess recovered refrigerant to at least
the purity specified in the Air-Conditioning, Heating, and
Refrigeration Institute (AHRI) Standard 700 and to verify this
purity using the analytical methodology prescribed in the
standard. Reclamation requires specialized machinery not
available at a particular job site or auto repair shop. The
technician will recover the refrigerant and then send it either to a
general reclaimer or back to the refrigerant manufacturer.
Recover - ANSWER To remove refrigerant in any condition from
an appliance and store it in an external container without
necessarily testing or processing it in any way.
,Recycle - ANSWER When referring to a refrigerant, to recycle
means to extract refrigerant from an appliance (except an MVAC)
and clean it for reuse in equipment of the same owner without
meeting all of the requirements for reclamation. In general,
recycled refrigerant is refrigerant that is cleaned using oil
separation and single or multiple passes through devices such as;
replaceable core filter-driers; that reduce moisture, acidity and
particulate matter. Under Section 609 of the Clean Air Act,
refrigerant can be removed from one car's air conditioner,
recycled onsite and then charged into a different car.
Refrigerant Pressure Classifications - ANSWER Shown below are
examples of refrigerants that fall in the "very high", "high", and
"low" pressure categories.
Small Appliance - ANSWER Any of the following products that is
fully manufactured, charged, and hermetically sealed in a factory
with five pounds or less of refrigerant: refrigerators and freezers
designed for home use, room air conditioners (including window
air conditioners and packaged terminal air conditioners),
packaged terminal heat pumps, dehumidifiers, under-the-counter
ice makers, vending machines, and drinking water coolers.
Self-Contained (Active) - ANSWER Uses its own means to draw
refrigerant out of the refrigeration system.
System-Dependent (Passive) - ANSWER Relies upon the
compressor in an appliance and/or the pressure of the refrigerant
in the appliance to remove the refrigerant into an external
container.
Technician - ANSWER Any person who, in the course of
maintenance, service, or repair of an appliance (except MVACs),
could be reasonably expected to violate the integrity of the
refrigerant circuit and thereby release Class I or Class II
, refrigerants into the environment. This term also means any
person who, in the course of disposal of an appliance (except
small appliances, MVACs, and MVAC-like appliances), could be
reasonably expected to violate the integrity of the refrigerant
circuit and thereby release refrigerants from the appliance into the
environment. Activities reasonably expected to violate the integrity
of the refrigerant circuit include but are not limited to: attaching or
detaching hoses and gauges to and from the appliance, adding or
removing refrigerant, adding or removing components, and cutting
the refrigerant line. Activities such as painting the appliance,
rewiring an external electrical circuit, replacing insulation on a
length of pipe, or tightening nuts and bolts are not reasonably
expected to violate the integrity of the refrigerant circuit. Activities
conducted on appliances that have been properly evacuated are
not reasonably expected to release refrigerants unless the activity
includes adding refrigerant to the appliance. Technicians could
include, but are not limited to installers, contractor employees, in-
house service personnel, and owners and/or operators of
appliances. This term also means any person disposing of
appliances, except for small appliances.
Type I Certification - ANSWER For technicians who maintain,
service, or repair small (household) appliances. Must pass the
Core exam and the Type I exam to receive a Type I certification.
Type 2 Certification - ANSWER For technicians who maintain,
service, repair or dispose of high pressure or very-high-pressure
appliances, except small appliances and Motor Vehicle Air
Conditioners (MVACs). Must pass the Core exam and the Type II
exam to receive a Type II certification.
Type 3 Certification - ANSWER For technicians who maintain,
service, or repair low-pressure appliances or dispose of low-
pressure appliances. Must pass the Core exam and the Type III
exam to receive a Type III certification.
