3.1 Coffee machine types
3.1.1
fully automatic machine
coffee machine, other than a vending machine, in which the preparation of the coffee starting from the
ingredients up to the delivered beverage is fully controlled by the machine based on the input of the user
Note 1 to entry: The user typically places a cup underneath and presses a button, and the machine does the rest.
3.1.2
traditional machine
coffee machine in which the preparation of coffee requires pressurized hot water to pass through grinded coffee
by one or more interventions of the user in process of preparation and delivery of coffee
EXAMPLES For intervention of the user the examples are manually filling of grinded coffee in the portafilter and manually
emptying after the dispensing of the coffee.
Note 1 to entry: The user prepares coffee (properly grounded), put it into portafilter and mounts the portafilter on the coffee
machine, then presses the button.
3.1.3
cold machine
switched off machine, mounted inside the testing chamber, left at testing conditions for a time of
16h00 min ± 10 min from the end of a heating phase of the machine, all delivery groups on, that lasted at least
1h
3.2
end of beverage delivery
time when the continuous flow of the delivery of the liquid beverage stops
Note 1 to entry: This is not the last drop of beverage delivered.
Note 2 to entry: This is not applicable in case of steam wand hot milk.
3.3
delivery time
time from when the command to deliver a beverage is given to the machine to the end of beverage delivery
EXAMPLE For command to deliver a beverage: press a button, activate a lever.
Note 1 to entry: The delivery time ends when the continuous flow stops, not the last drop, see 3.2.
3.5 Milk
3.5.1
cold milk
UHT cow liquid milk with a level of fat of 2,5 % to 4 %, a temperature of 5 °C ± 2 °C
Note 1 to entry: UHT means Ultra High Temperature.
