IEC Foreword
1) IEC (International Electrotechnical Commission) is a worldwide standardization organization composed of all national electrotechnical committees (IEC National Committees). The purpose of IEC is to promote international cooperation on standardization issues in the electrical and electronic fields. To this end, IEC, in addition to other activities, also publishes international standards. The formulation of these standards is entrusted to technical committees: any IEC National Committee interested in the technical issue can participate in the formulation work. International, governmental and non-governmental organizations that have relations with [EC can also participate in the formulation work. IEC and ISO (International Organization for Standardization) work closely together on the basis of the two organizations. 2) IEC's formal resolutions or agreements on technical issues are made by technical committees represented by all national committees interested in the issue, and, as far as possible, express international consensus on the issues involved. 3) These resolutions or agreements are published in the form of standards, technical reports or guidelines for international use and are accepted by national committees in this sense.
4 In order to promote international unification, IEC national committees agree to adopt the contents of IEC international standards as national or regional standards to the greatest extent possible. The differences between IEC standards and corresponding national or regional standards should be clearly pointed out in the latter. 5) IEC does not prescribe a clear procedure for expressing consensus and does not bear any responsibility for any equipment claiming that it conforms to an IEC standard.
This international standard was prepared by IEC Technical Committee 61 "Safety of Household and Similar Electrical Appliances". This standard constitutes the third edition of IEC 60335-2-14 and replaces the second edition of IEC 60335-2-14 and its amendments. It also replaces the second edition of IEC 60335-2-33:1987 "Particular requirements for coffee grinders and coffee grinders" and its first amendment (1990), and cancels this standard.

This chapter in GB 4706.1-1998 is applicable except for the following. 2.2.9 This clause is replaced by the following:
Normal operation: The appliance is operated under the specified conditions or at rated input power (if this is less favorable). NOTE
1 If conditions are not specified, the appliance shall be operated under the most unfavourable load conditions specified in the instructions for use. 2 The rated power input is the constant torque obtained when the appliance is placed in the normal use position and is not subjected to unbalanced forces greater than those occurring in normal use. 3 Operation at rated power input is considered to be less favourable if the power input measured in the test of 10.1 deviates from the rated power input by more than the following:
■ For appliances with a rated power input not exceeding 300 W, the deviation is -20 %; · For appliances with a rated power input exceeding 300 W, the deviation is -15 % or -60 W, whichever is the greater. 2.2.9.1 When a food mixer with a beater for mixing cake batter is operated, the blades of the beater shall be placed as close as possible to the bottom of the mixing bowl filled with dry sand of a size between 170 μm and 250 μm. The height of the sand in the mixer is about 80% of the length of the effective part of the beater.
Food mixer with a kneader for mixing dough, the kneader works in a mixing bowl filled with a mixture of flour and water. Notes
1 The protein content of the flour is (10±1)%, which can be ignored. There are no chemical additives in the flour. 2 In case of doubt, the flour used should be produced not less than 2 weeks and not more than 4 months, and the flour should be stored in plastic bags with as little air as possible.
The mixing bowl is filled with flour, the mass of which is equal to 35% of the capacity of the mixing bowl in cm, in g. For every 100 g of flour, add 72 g of water at a temperature of 25℃±1℃.
NOTE 3: In case of doubt, the amount of water may be 1.2 grids of water required to obtain a consistency of 500 Brabender units at a temperature of 29°C ± 1°C as measured by a consistency meter. For hand-held food mixers, the kneader moves in a "B" shape at a speed of 10 to 15 times per minute. The kneader touches the wall of the bowl at the diagonal points and touches the bottom at the bottom. If no mixing bowl is provided, a mixing bowl with a height of about 13 cm, an inner diameter of about 17 cm at the top and an inner diameter of about 15 cm at the bottom, and a conical inner surface should be used. Its inner surface is smooth and the walls and bottom are smoothly connected. 2.2.9.2 Food processing shall be carried out in accordance with the provisions for food filters and mixers with mixing dough. However, the amount of mixing is the maximum specified in the instructions for use. If high-speed rotating accessories are used to make dough, only 60 g of water is added for every 100 g of flour.
