This standard specifies methods for measuring the performance of electric household portable appliances for cooking, grilling and similar use. This standard defines the main performance characteristics of such appliances which are of interest to the user, and specifies methods of measurement. This standard is concerned neither with safety nor performance requirements. Taking into account the lower grade of accuracy and repeatability, due to the variations in time, 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 a single appliance in different laboratories. This standard does not apply to microwave ovens, electric cooking ranges, hobs, ovens and grills for household use, nor to appliances designed exclusively for commercial or industrial use.
