HAND-HELD TOOLS, TRANSPORTABLE TOOLS AND LAWN AND GARDEN MACHINERY – SAFETY – Part 2-10: Particular requirements for hand-held mixers FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62841-2-10 has been prepared by IEC technical committee 116: Safety of motor-operated electric tools.

NOTE In Europe (EN 62841-2-10), Annex I is normative. I.2 Noise test code (grade 2) This clause of Part 1 is applicable except as follows: I.2.4 Installation and mounting conditions of the power tools during noise tests Addition: Mixers are suspended vertically with no mixer basket installed. I.2.5 Operating conditions Addition: Mixers are tested at no-load, all speed setting devices adjusted to the highest value. I.3 Vibration This clause of Part 1 is applicable except as follows: I.3.3.2 Location of measurement Addition: Figure I.101 shows the position for different types of tools. I.3.5.3 Operating conditions Addition: I.3.6.2 Declaration of the vibration total value Addition: BS EN 62841-2-10:2017 IEC 62841-2-10:2017 © IEC 2017 Annex I (informative) Measurement of noise and vibration emissions Mixers are tested at no-load, all speed setting devices adjusted to the highest value. During the test, the tool is held vertically. For the test, one simulated test mixer basket with a specified unbalance as shown in Figure I.102 is mounted to the output spindle or, for tools with more than one output spindle, to one of the output spindles. The test mixer basket consists of a steel rod and an aluminium wheel with an unbalance, see Figure I.103, mounted appropriately to the steel rod. The upper end of the steel rod may be modified in order to fit to the output spindle. NOTE Experimental investigations have shown that the vibration emission values of mixers when mixing material are similar or even lower than at no-load, because the main source of vibration is the unbalance of the mixer basket(s). Hence, the above test results in a worst case value. The vibration total value ah of the handle with the highest emission and the uncertainty K shall be declared.

If a clause is stated in this annex, its requirements replace the requirements of the main body of this Part 2-10 unless otherwise specified. K.8.14.1.101 Items d), f) and h) are not applicable. K.12.2.1 This subclause is not applicable. NOTE In Europe (EN 62841-2-10), the following additional subclause applies: K.21.18.Z101 Isolation and disabling device Tools with an integral battery shall either be equipped – with an isolation device to prevent the risk of injury from mechanical hazards during servicing or user maintenance; or – with a disabling device that prevents unintentional starting of the tool. An isolation device shall – provide disconnection of all poles of the battery from the serviceable region of the tool; – be equipped with an unambiguous indication of the state of the disconnection device which corresponds to each position of its manual control (actuator); – be provided with protection against accidental reconnection. NOTE 1 Examples of methods to achieve this disconnection include removable jumpers, integral batteries that can be disconnected for servicing or user maintenance, or an electromechanical power switch with a direct mechanical link between the actuator and the contact. NOTE 2 The risk of accidental reconnection for a power switch is addressed by the requirement of 21.18.1.2. The other examples in NOTE 1 achieve this by the necessary actions for reconnection. A disabling device may be achieved by any of the following: – a self-restoring or non-self-restoring lock-off device where two separate and dissimilar actions are necessary before the motor is switched on (e.g. a power switch which has to be pushed in before it can be moved laterally to close the contacts to start the motor). It shall not be possible to achieve these two actions with a single grasping motion or a straight line motion; – a removable disabling device provided with the tool where it shall not be possible for the tool to be operated when either applied or removed. Compliance is checked by inspection and by manual test. IEC 62841-2-10:2017 © IEC 2017 Annex L (normative) Battery tools and battery packs provided with mains connection or non-isolated sources All clauses of the main body of this Part 2-10 apply unless otherwise specified in this annex. If a clause is stated in this annex, its requirements replace the requirements of the main body of this Part 2-10 unless otherwise specified.
