2 Definitions
Add, after definition 2.2.9.3, the following new definition:

2.2.9.4
normal operation of an ice-cream appliance

operation of the appliance using the maximum quantity of the mixture of ingredients indicated

in the instructions. The mixture used being that which gives the most unfavourable results, the

mixture being at an initial temperature of 23 °C ± 2 °C
Replace definition 2.109 by the following:
2.109
flammable refrigerant
refrigerant with a flammability classification of group 2 or 3 according to ISO 5149
NOTE For refrigerant blends which have more than one flammability classification the most unfavourable
classification is taken for the purpose of this definition.
Add, after definition 2.109, the following new definitions:
2.110
ice-cream appliance
compression-type appliance which is used to make ice-cream
2.111
free space
space with a volume exceeding 60 l where a child can be entrapped and which is accessible
after opening any door, lid or drawer and removing any detachable internal part, including
shelves, containers or removable drawers which are themselves only accessible after opening
any door or lid. In calculating the volume, a space with any single dimension not exceeding
150 mm or any two orthogonal dimensions each of which do not exceed 200 mm is ignored.

4 General conditions for the tests

4.3 Replace the first paragraph by:
Before starting the tests:
– ice-cream appliances are operated empty at rated voltage for 1 h or the maximum setting
of an incorporated timer, whichever is shorter;
– other compression-type appliances shall be operated at rated voltage for at least 24 h,
then switched off and left to stand for at least 12 h.

4.7 Replace the first paragraph by:

For ice-cream appliances, tests specified in clauses 10, 11 and 13 are carried out at an

ambient temperature of 23 °C ± 2 °C.

For other appliances, tests specified in clauses 10, 11, 13 and subclause 19.103 are carried

out at an ambient temperature of:

32 °C ± 1 °C on appliances of extended temperate (SN) and temperate (N) classes;

38 °C ± 1 °C on appliances of subtropical (ST) class;

43 °C ± 1 °C on appliances of tropical (T) class;
Before starting these tests, the appliance with the doors or lids open is brought to within 2 K of
the ambient temperature specified.

6.101 Replace the first line by:
Appliances, other than ice-cream appliances, shall be of one or more of the following climatic
classes:
7 Marking and instructions
7.1 Modification:
Replace the third dash by :
– rated power input in watts or rated current in amperes, except that compression-type
appliances, other than ice-cream appliances, shall be marked only with the rated current
in amperes;
Add the following:
For compression-type appliances, the defrosting power input in watts shall be marked
separately if the current corresponding to the defrosting power input is greater than the rated

current of the appliance.
7.12 Add the following:
The instructions for ice-cream appliances shall include the ingredients and maximum quantity
of mixtures that can be used in the appliance.

any incorporated timer operates, whichever occurs first.

10.2 Replace the text under "Addition" by the following:

The appliance is operated for a period of 1 h or the maximum setting of an incorporated timer
which ever is shorter. Excluding starting current, the maximum value of the current averaged
over any 5 min period is obtained. The interval between current measurements shall not
exceed 30 s.
Replace note 101 by the following:
NOTE 101 Starting current is considered to be excluded if the first current measurement is made approximately
1 min after starting.
11 Heating
