Endorsement notice
The text of the International Standard IEC 60661:1999 + A1:2003 + A2:2005 was approved by CENELEC as a
European Standard with agreed common modifications.

1 Addition of an Introduction
Add the following between the foreword and Clause 1:
Introduction
IEC 60661:2006-02 (consolidated edition of IEC 60661:1999 + A1:2003 + A2:2005) focuses mainly on filter
coffee makers; capsule & pad makers are completely missing, and many clauses cannot be applied to them.
Therefore, a complete reworking of the standard could solve that inadequate status; this will be done later.
2 Modification to Clause 1 "Scope and object"
In NOTE 2, add "and capsule and pod/pad makers" after "espresso coffee makers".
3 Modification to Clause 2 "Normative references"
Replace the text by the following:
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated references,
the latest edition of the referenced document (including any amendments) applies.
EN 50564:2011, Electrical and electronic household and office equipment – Measurement of low power
consumption (IEC 62301:2011, mod.)
EN 60584-2, Thermocouples – Part 2: Tolerances (IEC 60584-2)
EN ISO 3696:1995, Water for analytical laboratory use – Specification and test methods (ISO 3696:1987)
ISO 3972:1991, Sensory analysis – Methodology – Methods of investigating sensitivity of taste
ISO 4121:1987, Sensory analysis – Methodology – Evaluation of food products by methods using scales
4 Modifications to Clause 3 "Definitions"
Replace definition 3.4 by the following:
3.Z1
pressure coffee maker
coffee maker with water heated and forced through ground coffee and filter by steam pressure or mechanical
pump
3.Z1.1
espresso coffee maker
coffee maker with heated water that is forced through ground coffee and filter by steam pressure, manual
piston drive or mechanical pump, with a mechanical pump pressure equal to or higher than 10 bar

- 5 - EN 60661:2014
3.Z1.2
low pressure coffee maker
coffee maker with heated water that is forced through ground coffee and filter by steam pressure, manual
piston drive or mechanical pump, with mechanical pump pressure lower than 10 bar
Note 1 to entry: Electrical "moka pot" coffee maker with water heated and forced through ground coffee and filter by
steam pressure is a low pressure coffee maker.
5 Modification to 23.2 "Taste of the coffee"
In the second paragraph, replace "ISO 3696" by "EN ISO 3696".
6 Modification to Clause 25 "Descaling test"
Delete the second paragraph.
7 Modification to Clause 26 "Energy consumption"
Replace the text of Clause 26 by the following:
26.Z1 Special conditions and measurement accuracy
26.Z1.1 Ambient temperature
Ambient temperature condition for energy consumption measurements shall be 23 °C ± 2 °C.
26.Z1.2 Storage of appliances
Appliances are stored at ambient temperature for at least 6 h before measurements.
26.Z1.3 Energy measurement accuracy
a) The energy measurements shall be accurate to ± 1,5 %.
b) The resolution of energy measurements shall be 1 Wh or better.
c) Standby and off mode are measured according to EN 50564:2011.
For energy measurements during active modes, a) and b) are applicable.
For appliances connected to more than one phase, the power measurement instrument shall be equipped to
measure total power of all phases connected.
26.Z1.4 Weighing accuracy
The uncertainty of the balance for weighing filter coffee shall be less than or equal to 1,0 g.
The uncertainty of the balance for weighing the mass of brewed coffees and steaming water for pressure
coffee makers shall be less than or equal to 0,1 g.

26.Z1.5 Temperature measurement accuracy
The uncertainty of the temperature measurements relevant for energy measurements – ambient and water or
coffee – shall be less than or equal to ± 1,5 K.
Temperature measurement shall be conducted in line with EN 60584-2.
26.Z2 Pressure coffee makers
26.Z2.1 Categories and designations
Categories and designations of coffee makers that are to be measured as "pressure coffee makers" are fully
automatics, capsule, pod or pad makers, and makers with manual piston drive. "Moka pot" espresso coffee
makers are not in the scope.
26.Z2.2 Coffee period
26.Z2.2.1 Preparations
All features (such as auto-power-down, heating systems, grinding, brewing, rinsing, etc.) are to be set in
factory default mode except the amount of coffee used per cup.
The coffee beans used shall be 100 % Arabica.
The capsules/pods/pads used are according to manufacturer’s instruction and shall be specified in the
measurement report.
The beakers used shall be as described in Annex ZA.
Water temperature (T ) in the reservoir shall be 23 °C ± 1 ºC.
w
Water temperature (T ) and ambient temperature (T ) are measured before start and reported.
w A
If the amount of coffee used per cup can be adjusted, the settings shall be as close to 40 g and 120 g as
possible. The chosen settings shall be reported.

If refilling water or emptying the (used) coffee grounds is needed during the measurement, this should be done
in a waiting period. The temperature of the water shall be 23 °C ± 1 °C.

The appliance is switched on and the energy consumption measurement starts and continues for 100 min ±
2 s.
The temperature of the coffee is measured within 5 s after serving and a short stirring in the middle of the
plastic beaker, with a rod of negligible heat capacity.
The first brewing cycle starts 60 s ± 2 s after the maker is ready for brewing. This is a 40 g coffee, and
temperature (T ) and mass of coffee (M ) are measured and to be reported.
C1 C1
In case the temperature does not reach 76 °C, a correction of the energy is made as described in 26.Z2.6.2.
In case the actual coffee mass deviates from the nominal, a correction is made as described in 26.Z2.6.2.
The second brewing cycle is done 60 s ± 2 s after the maker has finished the first brewing cycle. If needed, the
maker is to be re-activated. This is a 120 g coffee, and temperature (T ) and mass of coffee (M ) are
C2 C2
measured and to be reported. For makers where there is no possibility to change the cup size, two cups of
same size are brewed, irrespectively of size. After that, the energy measurement shall continue without any
further interaction until minute 30.
30 min ± 2 s from start, the third brewing is made, a 2 x 40 g coffee is made. If needed, the maker is to be re-
activated. The mass of coffee (M ) is measured and to be reported. After that, the energy measurement shall
C3
continue without any further interaction.
In case the maker can only make single coffees, the double coffees are replaced by 2 singles of the same
weight to be made immediately in sequence. The mass of both coffees is measured and to be reported.
40 min ± 2 s from start, the accumulated energy consumption is measured and to be reported (E ).
100 min ± 2 s from start, the accumulated energy consumption is measured and to be reported (E ).
26.Z2.3 Steam function
26.Z2.3.1 Preparations
The beaker used shall be as described in Annex ZA.
The water temperature at the start in the beaker (T ) shall be 15 °C ± 2 °C.
S
100 g ± 1 g water is heated up to 55 °C ± 2 ºC in the beaker.
