(8)
A family must not contain more than 25 models.
Specific energy consumption
(9)
For the purposes of subclause (2)(a)(i), the specific energy consumption of a refrigerated cabinet is equal to,—
(a)
for an RDC, the amount SEC in kWh per 24 hours per m2 as calculated in accordance with clause 5.3.6.3.5 of ISO 23953-2; and
(b)
for an RSC, the amount SEC in kWh per 24 hours per m3 as calculated in accordance with subclause (10); and
(c)
for a scooping cabinet, the amount SEC in kWh per 24 hours per m2 as calculated in accordance with clause 6.3.7.3.5 of EN 16838; and
(d)
for an ice cream freezer cabinet, the amount SEC in kWh per 24 hours per m3 as calculated in accordance with clause 6.3.6.6.4 of EN 16901.
(10)
In subclause (9)(b), for an RSC, the amount SEC is given by following formula:
SEC = energy consumption ÷ net volume
- energy consumption
is the cabinet’s energy consumption in kWh per 24 hours (see clause 16)
- net volume
is the cabinet’s net volume in cubic metres (see clause 8).

Part 2 Variations to standards and related matters
Variations to standards
22 Variations that relate to ISO 23953-2
(1)
The following table sets out the variations that relate to ISO 23953-2 for the purposes of the definition of that standard in clause 9:
| Item | | The following provision of ISO 23953-2: | | is taken to be varied by: |
|---|
| 1 | | clause 4.1.6 | | inserting, before the Note to the clause: “Remote temperature monitoring is permitted.”
|
| 2 | | paragraph (b) of clause 5.3.2.3.2 | | replacing “chilled vertical cabinets” with “open cabinets” |
| 3 | | paragraph (d) of clause 5.3.2.3.2 | | |
| 4 | | clause 5.3.2.3.2 | | inserting, after paragraph (d): “(e) The loading height for closed cabinets shall equal half height loading of test packages.” |
| 5 | | description of Figure 27 | | replacing “frozen” with “closed” |
| 6 | | clause 5.3.2.7.1 | | inserting, after paragraph (b) of the clause: “Automatic lighting function switches are permitted. Should a cabinet have no automatic lighting control function fitted, the lights are to be operated continuously for the duration of the test.” |
| 7 | | clause 5.3.3.2 | | replacing the clause with: “5.3.3.2 Closed refrigerated cabinets (a) The test for closed refrigerated cabinets shall always be carried out on the complete cabinet, regardless of the number of doors or lids. Each door or lid shall be opened six times per hour. Doors that are used for service, cleaning or loading of the cabinet only shall not be opened during this test. Where more than one door or lid pertains to the cabinet under test, the sequence in which the doors and lids are opened shall be staggered, ie, in the case of two doors: door 1 at 0 min, door 2 at 5 min, door 1 at 10 min, door 2 at 15 min, etc. Hinged lids and doors shall be opened beyond an angle of 60°. Sliding glass doors or lids shall be opened beyond 80 % of the maximum area which can be opened. The door or lid shall be opened for a total of 6 s. During this opening period, the doors or lids shall be kept open beyond the minimum required opening for 4 s. Prior to the start of the 12-h period of door opening, each door or lid shall be opened once for 3 min. Where a cabinet is provided with more than one door or lid, each door or lid shall be opened once for 3 min consecutively. Within the test period, the doors or lids shall be opened cyclically for 12 h within 24 h. The 12-h cycle of door or lid opening shall start at the beginning of the test period. (b) If the refrigerated cabinet is fitted with a lighting system, this shall be switched on 1 h before starting the opening cycle. During the test, lighting pertaining to the cabinet shall be lit continuously and anti-sweat heaters shall run for the duration of the test period unless controlled by a time-clock, smart sensor or similar automatic device. Where a cabinet is fitted with an automated lighting control, the tests shall be conducted using the pre-set lighting regime. (c) In all test conditions, maximum energy consumption and minimum efficiency should be determined as worst case.” |
(2)
For the purposes of items 5 and 7 of the table in clause 16(1), and of clauses 7(2) and 20(4) (to the extent that they apply to low-sales-volume RSCs), ISO 23953-2 applies as if, in addition to the variations specified in subclause (1),—
(a)
references in that standard to Commercial Refrigerated Display Cabinets were references to low-sales-volume RSCs:
(b)
for normal-duty or heavy-duty RSCs, tests were required to be undertaken at test room climate class 4.
