MEASURING METHODS
FOREWORD
1)
The IEC (International Electrotechnical Commission) is a worldwide organization for standardization
comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to
promote international cooperation on all questions concerning standardization in the electrical and
electronic fields. To this end and in addition to other activities, the IEC publishes International Standards.
Their preparation is entrusted to technical committees; any IEC National Committee interested in
the subject dealt with may participate in this preparatory work. International, governmental and
non-governmental organizations liaising with the IEC also participate in this preparation. The IEC
collaborates closely with the International Organization for Standardization (ISO) in accordance with
conditions determined by agreement between the two organizations.
2)
The formal decisions or agreements of the IEC on technical matters, prepared by technical committees on
which all the National Committees having a special interest therein are represented, express, as nearly as
possible, an international consensus of opinion on the subjects dealt with.
3)
They have the form of recommendations for international use published in the form of standards, technical
reports or guides and they are accepted by the National Committees in that sense.
4)
In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
International Standard IEC 619 has been prepared by sub-committee 59G: Small kitchen
appliances, of IEC technical committee 59: Pe
rformance of household electrical appliances.
This second edition cancels and replaces the first edition issued in 1978 and its
amendment 1 (1992). It constitutes a technical revision.
The text of this standard is based on the following documents:
DIS Report on Voting
59G(CO)25
59G(CO)33
Full information on the voting for the approval of this standard can be found in the repo
rt

Annex A forms an integral pa
rt of this standard.

ELECTRICALLY OPERATED FOOD PREPARATION APPLIANCES -
MEASURING METHODS
1 Scope and object
1.1 Scope
This International Standard applies to electrically operated food preparation appliances for
household use.
The purpose of this standard is to state and define test methods of measuring the
functions that can be carried out by means of household electrical food preparation
appliances, which are of interest to the user and to give some guidelines for the evaluation
of test results.
Taking into account the lower grade of accuracy and repeatability, due to variations in
time and origin of test materials and ingredients and to the influence of the subjective
judgement of test operators, the described test methods may be applied more reliably for
comparative testing of a number of appliances at approximately the same time, in the
same laboratory, by the same operator and with the same utensils, rather than for testing
of single appliances in different laboratories.
As there is no definition of a given type or size of oven, and as a number of the tests
involve baking of the final product in order to make a determination of volume, a variation
in results can be expected between ovens used. All comparative tests should be under-
taken in the same oven.
1.2 Aspects excluded from the scope
This standard is not concerned with safety.
It does not apply to appliances designed exclusively for commercial or industrial use.
Attention is drawn to the fact that sometimes the same result may be obtained using
different functions.
2 Normative references
Void.
NOTE - Other clauses which include normative references will be developed later.
3 Definitions
For the purpose of this International Standard the following definitions apply:
3.1 Terms used to define the functions
3.1.1 whisking: To incorporate air and increase the volume of egg-whites.
619 ©IEC:1993 - 11 -
whipping cream:
3.1.2 To incorporate air and increase the volume of cream.
3.1.3 beating: To mix and incorporate air (e.g.: cake batter).
3.1.4 heavy mixing: To incorporate ingredients evenly into a heavy mixture without
chopping (e.g.: fruit cake containing glacé cherries).
3.1.5 mixing: To combine ingredients evenly (e.g.: pastry, pie).
To work a heavy mixture to form a smooth, pliable mass.
3.1.6 kneading:
3.1.7 blending/pureeing: To make semi-solid ingredients liquid or to chop with liquid
(e.g.: babyfood, fruit, soup).
3.1.8 emulsifying: To combine together insoluble liquids so that one or more is
suspended in droplets throughout the other (e.g.: mayonnaise).
3.1.9 chopping: To reduce solid ingredients to small particles (e.g.: meat, onions,
almonds).
3.1.10 slicing: To cut into slices (e.g.: carrots. cucumber, leeks).
3.1.11 shredding: To reduce to small strips (e.g.: carrots, cheese).
3.1.12 french fry: To cut potatoes into the shape of French fries.
NOTE - The definition of other functions is under consideration.
3.2 Terms used to define the major families of appliances
3.2.1 mono-function appliance: Appliance designed to perform only one function.
3.2.2 multi-function appliance: Appliance designed to perform more than one function.
Appliances can be either hand-held type or table type.
NOTE - Sometimes, for some appliances, it may be necessary to change the attachments or tools in order
to perform the different functions.

5 General conditions for measurements
Unless otherwise specified, the measurements are conducted under the following
conditions.
5.1 General
The attachments, speed, tools and quantities of ingredients used shall be those recom-
mended by the manufacturer. In the absence of manufacturer's recommendations, the
quantities quoted shall be used. The ingredients specified have been selected primarily to
ensure uniform and reproducible results. A list of ingredients known to be suitable is given
in annex A. Unless otherwise stated, the appliance shall be operated in accordance with
the manufacturer's instructions.
5.2 Electrical supply
The measurements shall be made at rated frequency and at a voltage which is within
±0,5 % of the rated voltage or the mean of the rated voltage range.
NOTE - If the rated voltage differs from the nominal supply voltage of the count ry concerned, measurements
carried out at rated voltage may be misleading. Therefore, for comparative testing the voltage used for the
tests is to conform to the nominal supply voltage and this shall be reported.
5.3 Ambient temperature
The ambient temperature and the temperature of all utensils and ingredients shall be
maintained at (20 ± 5) °C, unless otherwise specified.
NOTE - In tropical climates, the ambient temperature may be (27 ± 5) °C but the temperature should be
recorded.
619 ©I EC:1993 - 15 -
5.4 Movement of hand-held machines
For whisking and whipping, a figure-of-eight movement shall be used unless it is imprac-
tical, in which case the beaters shall follow the shape of the bowl. The number of complete
movements shall not exceed fifteen per minute.
For other operations, hand-held machines shall be moved as necessary to achieve good
operation but at a speed not exceeding thirty movements per minute.
Hand-held machines supplied with bowl and stand shall be operated in accordance with
the manufacturer's instructions. If no instructions are supplied and it is obvious that the
bowl has to be moved, this is allowed but must be stated in the report.
5.5 Type of bowl
For appliances supplied with a bowl, the measurements shall be made using this bowl.
For appliances not supplied with a bowl, one of the bowls shown in figures 1, 2 and 3 shall
be used, choosing the most suitable for the function that has to be measured.
Ingredients
5.6
Where different ingredients have been used following particular national habits or parti-
cular country conditions a clear reference to these ingredients has to be given in the test
repo rt .
Where it is required that minimum and maximum quantities have to be processed, care
has to be taken that the same proportion between all ingredients is maintained.
Preliminary tests
5.7
Sometimes and for some functions it may be necessary to carry out, for a given appliance
or for a series of appliances, some preliminary tests in order to find out the time and the
procedure to obtain the best result.
5.8 Baking temperature
Where in the standard it is required to bake the prepared mixture, baking has to be made
in a normal (not forced convection) oven, at a suitable temperature in accordance with the
oven manufacturer's instructions.
