EPA 608 Type I Practice Test 2

Question 1

Type I certification under EPA Section 608 specifically covers technicians servicing which type of equipment?

Accepted Answer

Small appliances — hermetically sealed systems with 5 lbs or less of CFC/HCFC

Answer

Type I certification covers small appliances, defined under EPA Section 608 as household refrigerators, freezers, room air conditioners, dehumidifiers, vending machines, drinking water coolers, and similar equipment that uses 5 pounds or less of CFC or HCFC refrigerant in a hermetically sealed system manufactured and charged at the factory.

Question 2

What method of refrigerant recovery is typically used for Type I small appliances where the compressor is still operational?

Accepted Answer

System-dependent (passive) recovery using the appliance's own compressor

Answer

For small appliances with operational compressors, EPA allows system-dependent (passive) recovery — using the appliance's own compressor to pump refrigerant into a recovery cylinder. This method is efficient for small charges. If the compressor is not functional, a recovery machine must be used instead. Recovery is always required regardless of charge size.

Question 3

A household refrigerator typically uses which refrigerant in modern production?

Accepted Answer

R-134a (HFC-134a) or R-600a (isobutane)

Answer

Modern household refrigerators use either R-134a (an HFC with zero ODP) or R-600a (isobutane, a natural hydrocarbon refrigerant with zero ODP and very low GWP). R-12 was phased out of new refrigerators by 1994 due to its high ODP. R-22 is used in air conditioning systems, not refrigerators. R-410A is used in modern air conditioners.

Question 4

For Type I small appliances, what is the required recovery efficiency when the appliance's compressor is NOT functioning?

Accepted Answer

The system must be evacuated to 4 inches of mercury vacuum

Answer

When a Type I small appliance has an inoperable compressor, the technician must use a recovery machine to evacuate the system to at least 4 inches of mercury (Hg) vacuum. This standard applies because the appliance's compressor cannot assist with recovery, so a more rigorous method is needed to capture the remaining refrigerant effectively.

Question 5

Which organization certifies recovery equipment used for servicing Type I small appliances?

Accepted Answer

AHRI (Air-Conditioning, Heating, and Refrigeration Institute) certifies recovery equipment under EPA-approved programs

Answer

Recovery and recycling equipment used for EPA Section 608 compliance must be tested and certified by an EPA-approved equipment testing organization. AHRI has administered the certification program for recovery/recycling equipment, testing that equipment meets EPA efficiency standards. Technicians must use only certified equipment to comply with Section 608.
