5.3.2.3.1;
- ADD relevant requirements for the use of European standard pallets at the end
of 5.3.2.3.1;
- MODIFY the tolerance on the loading height in 5.3.2.3.2 a);
- ADD the explanatory notes for refrigerated cabinet for sensitive foodstuffs in
This Part has the following editorial modification:
- ADD the content of ISO 23953-2:2005’s amendment Amd.1:20012 (E).

Refrigerated display cabinets – Part 2:
Classification, requirements and test conditions
1 Scope
This Part of GB/T 21001 specifies requirements for the construction, characteristics
and performance of refrigerated display cabinets used in the sale and display of
foodstuffs. It specifies test conditions and methods for checking that the requirements
have been satisfied, as well as classification of the cabinets, their marking and the list
of their characteristics to be declared by the manufacturer.
This Part is not applicable to refrigerated vending machines or cabinets intended for
use in catering or similar non-retail applications; nor does it cover the choice of the
types of foodstuffs chosen to be displayed in the cabinets.
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 document (including any amendments) applies.
GB/T 21001.1-2015 Refrigerated display cabinets - Part 1: Vocabulary (ISO
23953-1:2005 + Amd.1:2012 (E), IDT)
ISO 817 Refrigerants - Designation system
ISO 9050 Glass in building - Determination of light transmittance, solar direct
transmittance, total solar energy transmittance and ultraviolet transmittance, and
related glazing factors
IEC 60335-2:89 Safety of household and similar electrical appliance - Part 2:
Particular requirements for commercial refrigerating appliances with an
incorporated or remote refrigerant condensing unit
EN 378-2 Refrigerating systems and heat pumps - Safety and environmental
requirements - Part 2: Design, construction, testing, marking and documentation
EN 60335-1 Safety of household and similar electrical appliances - Part 1: General
requirements
during the running-in period (see also 5.3.2.4) at a temperature equal to the lower limit
of the M-package temperature class with a tolerance (0°C, +2°C).
1 000 g packages and 500 g packages should be used.
To complete the loading, use test packages of the following sizes as fillers:
- 25 mm × 100 mm × 200 mm.
The test packages shall be arranged so as to form an even level.
Each refrigerated shelf area shall be loaded with test packages arranged in such a way
that they form rows with a length of 200 mm by the depth of the cabinet in the direction
of the airflow in the cabinet.
A clearance of 25 mm ± 5 mm shall be left between package rows and adjacent to the
internal end walls of the cabinet.
It is permitted to use partitions with a thickness of approximately 25 mm to position the
packages on condition that they have minimal effect on normal airflow and minimal
thermal conduction.
Lengthways, any remaining spaces shall be filled with test packages to obtain one or
two adjustment rows of which the width can measure from 100 mm up to 300 mm.
Depth-wise, any remaining spaces of less than 25 mm wide shall be filled with wooden
vertical dividers, placed approximately midway along the space between two M-
packages.
For roll-in cabinets or multi-deck cabinets with a loading height above 500 mm (see
Figure 25), some wood loading may be used. The thickness of each layer is not
specified. (EXAMPLE: Varnished pieces of exterior grade beech plywood with good
water resistance, 200 mm × 50 mm by the depth of loading.) If not otherwise stated in
the manufacturer's handbook/instructions or marked inside the cabinet, the packages
and the wood shall be loaded on standard Euro pallets (1200×800×144) 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 Figure
25, but inside the trolleys.
Note: Sensitive foodstuff loading type can be possible only for the top part (shelves) of this type
of cabinet.
Metallic grids can be used to support the test package loading on M-package rows and
the adjacent ones.
