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 undertaken in the same oven.
