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 (see www.iso.org/directives).

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. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www.iso.org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to

the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

www.iso.org/iso/foreword.html.

This document was prepared by Technical Committee ISO/TC 86, Subcommittee SC 7 Testing and

rating of commercial refrigerated display cabinets and Technical Committee CEN/TC 44, Commercial

refrigerated cabinets, catering refrigerating appliances and industrial refrigeration in collaboration.

Ice makers for commercial use — Classification,
requirements and test conditions
1 Scope

This Standard specifies methods for the measurement of energy consumption, water consumption, ice

production capacity and of harvested ice characteristics of ice makers for commercial use.

This Standard does not apply to:
— ice makers intended to be incorporated in appliances for household use;
— ice makers with remote condensing units.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

— IEC Electropedia: available at https:// www .electropedia .org/
3.1 Types of appliances
3.1.1
ice maker

factory-made appliance consisting of a condensing unit and ice-making section operating as an

integrated unit, with means for making and harvesting ice, also including means for storing or

dispensing ice, or both

Note 1 to entry: Ice makers are intended to produce ice in irregular shapes or flakes or ribbons or wafers as well

as uniformly shaped ice cubes.
3.1.1.1
ice maker with built-in condensing unit
appliance in which the refrigeration unit is an integral part of the cabinet
3.1.1.2
ice maker with remote condensing unit

appliance in which the compressors, condensers and liquid receivers (when required) are not supplied

with the cabinet
3.1.1.3
split ice maker

appliance in which the condenser is not integrated in the main ice making unit and the condenser and

piping are made in accordance with manufacturers indications using dedicated condensers

type ice maker
3.2.2
ice flakes

ice which contains at least 70 % flaked ice (and no more than 30 % water) which is produced by a

continuous type ice maker

ice maker that continually freezes and harvests ice flakes at the same time
3.3.3
modular-type ice maker
ice maker without storage means
3.3.4
self-contained ice maker

ice-maker in which the ice-making mechanism, storage compartment and condensing unit are

integrated within a cabinet
3.4
ice storage bin

factory-made container (not necessarily shipped in one package with the ice-maker) that forms or is

intended to form a non-refrigerated compartment for the storage of ice

Note 1 to entry: the container is equipped with additional devices (e.g. container support, carts, etc.).

3.5
separate storage compartment

non-refrigerated compartment for the storage of ice that is separate from the ice-making mechanism

Unless otherwise specified, measurements shall be made under test conditions and with equipment

set-up as specified in 4.2 to 4.5 and Clause 5.
4.2 Test room

The test room walls and ceilings shall be insulated to ensure that the temperature of both the inside

walls and the ceiling surface is within 2 °C of the ambient temperature.

Fluorescent or LED lighting shall be used owing to its high light output, low surface temperature and

low heat load on the test room.
The air flow shall be horizontal with a speed ≤0,25
