5.2 Construction
5.2.1 General
5.2.1.1 Strength and rigidity
The commercial beverage cooler and its parts shall be constructed with adequate strength and rigidity
for normal conditions of handling, transport and use and attention shall be given to the following:
a) interior fittings, including shelves, baskets, rails, etc. and their supports, shall be sufficiently strong
for the duty required;
b) where sliding shelves, baskets, trays or drawers are fitted they shall retain their shape and ease of
movement when fully loaded;
c) any fitments which are provided with stops to prevent accidental removal shall be self-supporting
when fully loaded and withdrawn to the limit of the stops.

Where drains, drip trays or evaporation receptacles are fitted, they shall have ample capacity and shall
be easily accessible and cleanable.
5.2.1.4 Joints and seams
All construction joints and seams within the net volume shall prevent the accumulation of potentially
contaminating substances.
All construction joints and seams within the net volume shall permit the easy removal of any deposits of
potentially contaminating substances.
5.2.2 Materials
5.2.2.1 General
The materials shall be durable and shall not favour the development of mould or emit odours.
Under normal conditions of use, materials in contact with foodstuffs shall be resistant to moisture and
shall neither be toxic nor contaminate them.
5.2.2.2 Wear resistance
Internal and external finishes shall be resistant to wear and capable of being cleaned effectively and
hygienically. Finishes shall not crack, chip, flake, rub off or soften under normal conditions of use or

5.2.3.1 Efficiency
The thermal insulation shall be efficient and permanently fixed. In particular, the insulating material
shall not be subject to shrinkage and shall not allow under normal working conditions an accumulation
of moisture.
5.2.3.2 Vapour barrier
Suitable means shall be used to prevent deterioration of the thermal insulation by the ingress of
moisture.
5.2.3.3 Containment of insulation material
Where the insulation space is vented to the inside, it shall be ensured that particles of the insulation
material cannot escape into the foodstuff display compartment.
For fibrous insulation materials, it shall not be possible to insert a rigid probe of 1 mm diameter
through any aperture which allows access to the insulating material, the probe being applied with
negligible force.
5.2.4 Refrigerating system
5.2.4.1 Design and construction

For commercial beverage coolers with components thereof which are charged with refrigerant prior to
transportation, the maximum ambient temperature during transit shall be taken into account. All
refrigerant containing components shall be in accordance with ISO 5149-2.
5.2.4.2 Condensation
There shall be suitable means to prevent water condensed on cold surfaces of the commercial beverage
cooler and its parts from harmfully affecting the operation of the refrigerating system or its controls.

For commercial beverage cooler fitted with doors or lids, the refrigerating system shall suffer no
damage if any door or lid in the commercial beverage cooler is left open while the commercial beverage
cooler is operating in an ambient temperature corresponding to the climate class (see Table 1) for
which the commercial beverage cooler is intended.
When the door or lid is kept open under normal operating conditions (for example, during product
loading) or is left open accidentally, any automatic motor overload protective device may come into
operation.
5.2.4.4 Refrigerant
When deciding on the refrigerant for the system, attention shall be given to the possible hazards
associated with the use of certain refrigerants and heat-transfer media or secondary refrigerant, due to
their toxicity, flammability etc. Guidance on this point is available in ISO 5149-2.
5.2.5 Electrical components
Electrical components shall be in accordance with EN 60335-2-89 and EN 60335-1.

6.1 General
When the characteristics of a commercial beverage cooler are to be verified, all the tests and inspections
shall be applied to one and the same commercial beverage cooler. These tests and inspections may also
be made individually for the study of a particular characteristic.
Table 2 lists the tests and inspections. Commercial beverage cooler shall comply with the requirements
specified in this part of standard using the appropriate test method.

6.2 Tests outside test room
6.2.1 General
The tests which may be carried out outside the test room deal with the inspection of construction
characteristics, physical dimensions and the absence of odour and taste.
6.2.2 Seal test for doors and lids
The effectiveness of doors or lids provided to ensure a seal shall be tested as follows (with the
commercial beverage cooler not running). See Figure 1.
Insert a strip of paper 50 mm wide, 0,08 mm thick and of a suitable length at any point of the seal. With
the door or lid closed normally on it the strip of paper shall not slide freely.
NOTE 1 Attention is drawn to the fact that some commercial beverage coolers having doors provided to ensure
an air seal are fitted with decompression valves which allow air to penetrate for a short period of time so that any
drop in pressure created inside the commercial beverage cooler may be compensated. No test is required for such
valves.
NOTE 2 The most unfavourable points can be found by inspecting the contact of the seal with the commercial
beverage cooler closed and lighted from the inside.
6.2.3 Test on durability of door and lid
6.2.3.1 Test condition/preparation
The purpose of these tests, carried out using the following procedures, is to check the durability of the
hinges and handles of doors. The ambient temperature shall be between +16 °C and +32 °C. The
refrigerating appliance shall be switched off.
6.2.3.2 Opening sequence
The movement of the door shall be controlled from an angle of 0° to an angle of opening between 5° and
45°, followed by a free movement of the door, the controlled movement being approximately sinusoidal.
The opening of the door shall take place in the first quarter of the period of the cycle.
6.2.3.3 Closing sequence
The number of cycles per minute shall be 10 to 25. External doors shall withstand 100 000 opening and
closing operations without deterioration which could be prejudicial to the airtightness of the door.
