This standard applies to electric coffee makers for household and similar use. It does not apply to appliances designed exclusively for commercial or industrial use. The object of this standard is to state and to define the main performance characteristics, which are of interest to the user and to describe the standard methods for measuring these characteristics. This standard is concerned neither with safety nor performance requirements. Taking into account the degree of accuracy and repeatability, due to variations in time and origin of test materials and ingredients and 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 single appliances in different laboratories. NOTE 1 Similar use denotes use in premises other than household, for example offices, where the appliance is used in a similar way to normal household use. NOTE 2 The measuring methods of this standard are specific to coffee makers with a view to the following types of coffee percolator, filter type coffee makers, espresso coffee makers and capsule and pod/pad makers; they may, however, be used for coffee makers having other systems, as far as this is reasonable
