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.
Amendment 1 to ISO 23953-2:2005 was prepared by the European Committee for Standardization (CEN)
Technical Committee CEN/TC 44, Commercial refrigerated cabinets, catering refrigerating appliances and
industrial refrigeration, in collaboration with Technical Committee ISO/TC 86, Refrigeration and air-
conditioning, Subcommittee SC 7, Testing and rating of commercial refrigerated display cabinets, in
accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

Replace the subclause with the following:
4.1.6.2 Temperature sensor location
The temperature sensor location shall be readily accessible to enable on-site testing for the correct
indication of temperature and replacement of the temperature measuring instrument on site in service.
NOTE 1 The temperature sensor of a thermometer is considered to be “readily accessible” if it can be reached
directly for examination. It can be necessary to remove access panel(s) to carry out replacement.
NOTE 2 For cabinets with natural convection cooling, the positioning of the temperature sensor in a guide tube is
also considered to be “readily accessible” if the sensor can be introduced into and removed from the guide tube
without a tool.
Wherever possible, the mounting method shall not supply heat to, or withdraw heat from, the temperature
sensor.
The temperature sensor shall be protected against heat radiation from the external ambient.
The temperature sensor's location is defined as part of the temperature test of the refrigerated display
cabinet. During the temperature test, air temperatures at the declared sensor location shall be measured
and these values noted in the test report.
NOTE 3 For electronic controllers, it is possible to display a calculated temperature.
NOTE 4 For the recording and display of temperatures, one or two temperature sensors can be used. The
temperature sensor can be the same as those used for controlling the refrigeration. An alarm can be activated in
case of error. This option is not in accordance with the requirements of EN 12830.
NOTE 5 It is the responsibility of the supplier and user to ensure that the location of the temperature sensor
complies with national regulation on temperature control of foodstuffs.

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.
Amendment 1 to ISO 23953-2:2005 was prepared by Technical Committee ISO/TC 86, Refrigeration and air-
conditioning, Subcommittee SC 7, and by Technical Committee CEN/TC 44, Commercial refrigerated
cabinets, catering refrigerating appliances and industrial refrigeration in collaboration.

DRAFT AMENDMENT ISO 23953-2:2005/DAM 1
Refrigerated display cabinets —
Part 2:
Classification, requirements and test conditions
AMENDMENT 1
Modify the fifth paragraph of clause 4.1.6.2 as follows:
The air return temperature shall be displayed. The temperature sensor shall be mounted to indicate the
temperature at the air-return side at the level of the clearly marked load limit line, except for vertical cabinets
for chilled foodstuffs, vertical closed cabinets for chilled and frozen foodstuffs, horizontal cabinets for chilled
and frozen foodstuffs with a front glass and cabinets with natural convection cooling.
Add the following text just after the two indents of b) in clause 4.1.6.2:
For horizontal cabinets for chilled and frozen foodstuffs with a front glass the temperature sensor probe
position shall be defined by option a).
For cabinets with natural convection cooling, the manufacturer defines the temperature sensor location.
Add the following text and figures after the third paragraph of clause 5.3.1.3.2:
For all vertical and semi-vertical cabinets, when the warm condenser air flow direction is across the testing
room air flow direction, from the front to the back of the cabinet, then an air deflector positioned as shown in
Fig. 1 shall be used in such a way to create a duct between the back of the cabinet and the vertical panel.
This duct shall be closed in the front end side towards the testing room airflow discharge direction and open in
the opposite side. On the top this duct shall be closed at the same height of the cabinet.
The distance d between the back of the cabinet and the vertical panel shall be specified by the manufacturer,
p
in compliance with EN ISO 23953-2, clause 5.3.2.1.

Figure 3 — Size end position of the air back duct
In general, the power of horizontal cabinets is much lower than that of vertical cases. The installation of a back
duct is therefore not necessary.
Usually plug-in horizontal cabinets are not intended to be placed against a wall so that a vertical partition
against the rear is not necessary (clause. 5.3.2.1)
The warm condenser air can be removed by the test room airflow.
The air movement of the test room shall be parallel to the longitudinal axis (EN ISO 23953-2, clause 5.3.2.2).
The direction of the warm condenser airflow should be the same as the test room air flow direction and not
opposed to it.
If this is not possible because of the cabinet’s design the condenser airflow should be across the test room
airflow direction (see Figure 4).

This test package may be a box made of plastic material of any density, and of 1 mm nominal thickness.
Cellular or foam material shall not be used. The case shall not incorporate any protrusions that would cause
the vertical separation of packages in a stack. Opposite faces shall be substantially parallel, and moulding
draft shall be the minimum practicable. Seams or joints shall not result in protrusions sufficient to cause
significant air gaps between adjacent packages.
Colour can be important if dark enough to be affected by ambient heat radiation; however, a pastel colour, e.g.,
light pink, pale blue or green, shall have no significant effect in normal surroundings.
The contents shall be water soaked into a porous material such as a natural, plastics or cellulose sponge.

For closed refrigerated cabinets with lids or doors hinged in a way that the rotation axis is perpendicular to the
longitudinal axis of the cabinet the direction of air flow shall be such that the air movement is parallel to the
plane of the cabinet display opening and the air enters the cabinet when the door(s) is (are) open.
The majority of the doors shall open in order to allow the air entry into the cabinet; if doors can be indifferently
hinged left and right, all doors shall open in the same direction.
Test room air movement shall be checked during the test in order to be sure that the test room is running
correctly. The method of checking is left to the discretion of testing authority.

If not otherwise stated in the manufacturer’s manual or marked inside the cabinet, the packages and the
wood shall be loaded on standard Euro pallets (1200 x 800 x 144) mm or if not applicable on a similar tray of
the same height. The surface of the pallet should be covered by a sheet of plastic or carton so that the
packages can be loaded properly.
If the cabinet is designed for the use of special storage trolleys, these trolleys shall be used for testing. In this
case the M-packages shall be positioned as specified in the above figure but inside the trolleys.
NOTE Sensitive foodstuff loading type might be possible only for top part (shelves) of this kind of cabinets.

5.3.2.3.3.2 Cross-section
For refrigerated base deck depths of less than or equal to 550 mm, or any shelf depth, M-packages shall be
located into two longitudinal sections, such that the M-package axis is situated at 50 mm from the back panel
and 50 mm from the front limit of loading (see Figures 14 to 27).
For refrigerated base deck depths of more than 550 mm, a third longitudinal section shall be placed midway
across the base deck depth with a tolerance of

d/2 mm from the air-discharge side for cabinets with forced-air cooling (see Figures 14 to 16, Figure
0
18 (a) and (b) and Figures 22 to 27), or
d/2 ± 50 mm for natural-convection-cooled cabinets equipped with two evaporators or having a
symmetrical layout (see Figures 19 to 21), or
+ 100
d/2 mm from the evaporator side for other natural-convection-cooled cabinets (see Figure 17).

In the height, for the base deck and each refrigerated shelf, M-packages shall be located into the lower and
upper loading layers. When the distance between the axes of M-packages is more than 400 mm, another M-
package layer shall be introduced (see Figures 23, 24 and 26).
1) The meaning of “intended for sensitive foodstuffs not suitable for multiple layer stacking” is that the foodstuffs are
displayed on tilted shelves where it is not possible to make a load level over 100 mm or for straight she
