only come from: -


recovery and recycling.


Refrigerant that is recovered can be returned to: -


the same system or other systems owned by the same person without restriction.




Refrigerant can not be called "reclaimed" unless it: - .


has been chemically analyzed and the refrigerant meets the ARI-700 standard.


The EPA can require a technician to demonstrate their ability to perform
proper procedures for recovering and/or recycling refrigerant. Failure to
demonstrate competency can result in: -


revocation of the technicians certification.

, What characteristic(s) of CFCs make them more likely to reach the stratosphere than most
other compounds containing chlorine? -


Refrigerants that contain chlorine but not hydrogen are so stable that they do not
break down in the lower atmosphere after being released. The chlorine or bromine
reacts with the ozone, causing it to change back to oxygen, thus destroying the ozone
layer.

A system is considered dehydrated when: -


the vacuum indicator shows you have reached and held the required finished vacuum.




Disposable refrigerant containers are used for ______


virgin refrigerant


Which refrigerant is an HCFC? -


R-123, R-124, R-22


What statement is true about an azeotropic refrigerant mixture? -


It is a mixture that acts like a single-component refrigerant over its entire range.


Chlorofluorocarbos (CFCs) and hydrochlorofluorocarbons (HCFCs) have which of the
following in common? -


It is a mixture that acts like a single-component refrigerant over its entire range.


To scrap a disposable cylinder, the internal cylinder pressure should be reduced to at
