ISO 5151:2017 specifies performance testing, the standard conditions and the test methods for determining the capacity and efficiency ratings of air-cooled air conditioners and air-to-air heat pumps.
ISO 5151:2017 is applicable to the following equipment:
-      non-ducted air-cooled air conditioners and non-ducted air-to-air heat pumps; or
-      ducted air conditioners and/or ducted heat pumps rated at less than 8 kW and intended to operate at an external static pressure of less than 25 Pa.
ISO 5151:2017 is limited to:
-      residential, commercial and industrial single-package and split-system air conditioners and heat pumps;
-      factory-made, electrically driven and use mechanical compression;
-      utilizing single, multiple and variable capacity components;
-      multiple split-system utilizing one or more refrigeration systems, one outdoor unit and one or more indoor units, controlled by a single thermostat/controller.
The requirements of testing and rating contained in this document are based on the use of matched assemblies.
ISO 5151:2017 is not applicable to the rating and testing of the following:
a)    water-source heat pumps or water cooled air conditioners;
b)    multi-split-system air conditioners and air-to-air heat pumps (follow ISO 15042 for the testing of such equipment);
c)    mobile (windowless) units having a condenser exhaust duct;
d)    individual assemblies not constituting a complete refrigeration system;
e)    equipment using the absorption refrigeration cycle;
f)     ducted equipment except for those specified in this clause (follow ISO 13253 for the testing of such equipment).
ISO 5151:2017 does not cover the determination of seasonal efficiencies, which can be required in some countries because they provide a better indication of efficiency under actual operating conditions.
NOTE          Throughout this document, the terms "equipment" and "systems" mean "air conditioners" and/or "heat pumps".
