ASHRAE Standard 15-2007, Section 7.5.3, allows the use
of Group A3 refrigerants where approved by the authority
having jurisdiction (AHJ). Small portable cooling appliances
and/or self-contained refrigeration systems are generally not
regulated by the model codes that form the basis for most local
regulation (see the 2006 International Mechanical Code, Section
106.2). Requiring specific local approvals from the AHJ
for systems using small amounts of flammable refrigerant
charge would be impractical, and inconsistent with national
code practice. This addendum allows the use of such systems
through an exception to Section 7.5.3.
