Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directives

Air-cooled air conditioners and air-to-air heat
pumps — Testing and calculating methods for seasonal
performance factors —
Part 3:
Annual performance factor
1 Scope
1.1 This part of ISO 16358 specifies the testing and calculating methods for seasonal performance
factor of equipment covered by ISO 5151, ISO 13253 and ISO 15042.
1.2 This part of ISO 16358 also specifies the seasonal performance test conditions and the corresponding
test procedures for determining the seasonal performance factor of equipment, as specified in 1.1., under
mandatory test conditions and is intended for use only in marking, comparison, and certification purposes.
1.3 This part of ISO 16358 does not apply to the testing and rating of:
a) water-source heat pumps or water-cooled air conditioners;
b) portable units having a condenser exhaust duct;
c) individual assemblies not constituting a complete refrigeration system; or
d) equipment using the absorption refrigeration cycle.
