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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 15502 was prepared by Technical Committee ISO/TC 86, Refrigeration and air-conditioning,
Subcommittee SC 5, Testing and rating of household refrigeration appliances.
This first edition cancels and replaces ISO 5155:1995, ISO 7371:1995, ISO 8187:1991 and ISO 8561:1995, of
which it constitutes a technical revision. It also incorporates the amendments ISO 7371:1995/Amd.1:1997,
ISO 8187:1991/Amd.1:1997 and ISO 8561:1995/Amd.1:1997.

INTERNATIONAL STANDARD ISO 15502:2005(E)
Household refrigerating appliances — Characteristics and test
methods
1 Scope
This International Standard specifies the essential characteristics of household refrigerating appliances,
factory-assembled and cooled by internal natural convection or forced air circulation, and establishes test
methods for checking the characteristics. These are type tests, and because of this, when verification of the
performance of a refrigerating appliance of a given type in relation to this International Standard is necessary,
it is preferable, wherever practicable, that all the tests specified be applied to a single unit. The tests can also
be made individually for the study of a particular characteristic.
NOTE For the safety requirements applicable to household refrigerating appliances, see IEC 60335-2-24, for noise
requirements applicable to household refrigerators and freezers, see ISO 8960, and for additional safety requirements
applicable to the refrigerating systems of household refrigerating appliances, see in ISO 5149.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced

4 Classification
4.1 Refrigerating appliances conforming to this International Standard are classified into four climate
classes or into a range of classes, see Table 1. The range of ambient temperatures in which the appliances
are intended to be used, and for which the required storage temperatures are to be met (see Clause 6), shall
be as specified in Table 1.
Table 1 — Climate classes
Class Symbol Ambient temperature range
°C
Extended temperate SN + 10 to + 32
Temperate N + 16 to + 32
Subtropical ST + 16 to + 38
Tropical T + 16 to + 43
4.2 Refrigerator-freezers conforming to this International Standard are classified into the following two
types:
a) refrigerator-freezer type I — having a single, user-adjustable temperature control device for regulating the
temperatures of the fresh-food storage compartment and of the food freezer compartments;
b) refrigerator-freezer type II — having user-adjustable means for the separate regulation of the
temperatures of the fresh-food storage compartment and of the food freezer compartments.
NOTE Where there is another kind of compartment, there can be additional means of regulating that compartment's
temperature.
5 Materials, design and manufacture
5.1 General
Refrigerating appliances shall be constructed in such a manner as to ensure adequate performance and
durability in use. Their performance in use is checked by applying a series of relevant tests, which shall be
recorded in the final test report (see Clause 19).
5.2 Materials and finishes
Materials used inside refrigerating appliances shall not transmit odours or taste to food. A test procedure for
guidance is given in Annex C.
Materials used inside refrigerating appliances shall not contaminate food placed in contact with them nor
transmit poisonous substances to food. They shall be resistant to the action of moisture and food acids.
All surface finishes shall be resistant to impact, sufficiently hard, colour-fast, smooth, easily washable, and
resistant to damage by moisture and by food acids.
5.3 Thermal insulation and air-tightness
The thermal insulation of the refrigerating appliances shall be efficient. In particular, the insulating material
shall not be subject to shrinkage and shall not allow, under normal working conditions, an excessive
accumulation of moisture.
