ISO/CEN PARALLEL PROCESSING
This draft has been developed within the European Committee for Standardization (CEN), and
processed under the CEN-lead mode of collaboration as defined in the Vienna Agreement.
This draft is hereby submitted to the ISO member bodies and to the CEN member bodies for a parallel
five-month enquiry.
Should this draft be accepted, a final draft, established on the basis of comments received, will be
submitted to a parallel two-month approval vote in ISO and formal vote in CEN.

To expedite distribution, this document is circulated as received from the committee
secretariat. ISO Central Secretariat work of editing and text composition will be undertaken at
publication stage.
Pour accélérer la distribution, le présent document est distribué tel qu'il est parvenu du

Secrétariat central de l'ISO au stade de publication.

THIS DOCUMENT IS A DRAFT CIRCULATED FOR COMMENT AND APPROVAL. IT IS THEREFORE SUBJECT TO CHANGE AND MAY NOT BE REFERRED TO
AS AN INTERNATIONAL STANDARD UNTIL PUBLISHED AS SUCH.
IN ADDITION TO THEIR EVALUATION AS BEING ACCEPTABLE FOR INDUSTRIAL, TECHNOLOGICAL, COMMERCIAL AND USER PURPOSES, DRAFT
INTERNATIONAL STANDARDS MAY ON OCCASION HAVE TO BE CONSIDERED IN THE LIGHT OF THEIR POTENTIAL TO BECOME STANDARDS TO WHICH
REFERENCE MAY BE MADE IN NATIONAL REGULATIONS.
RECIPIENTS OF THIS DRAFT ARE INVITED TO SUBMIT, WITH THEIR COMMENTS, NOTIFICATION OF ANY RELEVANT PATENT RIGHTS OF WHICH THEY
ARE AWARE AND TO PROVIDE SUPPORTING DOCUMENTATION.

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.

l length of the air back duct = length of the cabinet
h height of the air back duct = height of the cabinet
d  depth of the air back duct

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).
