____________ ELECTRIC MOTOR-OPERATED HAND-HELD TOOLS, TRANSPORTABLE TOOLS AND LAWN AND GARDEN MACHINERY – SAFETY – Part 2-2: Particular requirements for hand-held screwdrivers and impact wrenches 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.

For impact wrenches, replace the test of Part 1 as follows: An impact wrench is operated with no-load for 12 h at a voltage equal to 1,1 times the highest rated voltage or 1,1 times the upper limit of the rated voltage range and then for 12 h at a supply voltage equal to 0,9 times the lowest rated voltage or 0,9 times the lower limit of the rated voltage range. The 12 h of operation need not be continuous. If applicable, the tool is adjusted to the maximum attainable speed. The tool may be switched on and off by means of a switch other than that incorporated in the tool. Each cycle of operation comprises an “on” period of 100 s and an “off” period of 20 s, the “off” periods being included in the specified operating time. During the test, the tool is placed in three different positions, the operating time, at each voltage, being approximately 4 h for each position. NOTE The change of position is made to prevent abnormal accumulation of carbon dust in any particular place. Examples of the three positions are horizontal, vertically up and vertically down. IEC 62841-2-2:2014 © IEC 2014 After this, the impact wrenches are operated intermittently for 12 h at a supply voltage equal to 1,1 times the highest rated voltage or 1,1 times the upper limit of the rated voltage range, then for 12 h at a supply voltage equal to 0,9 times the lowest rated voltage or 0,9 times the lower limit of the rated voltage range. Each cycle of operation comprises a tool impacting for a period of 1 s and a resting period of 9 s with the tool switched “off”, the “off” periods being included in the specified operating time. During these tests, replacement of the carbon brushes is allowed, and the tool is oiled and greased as in normal use. If mechanical failure occurs and does not impair compliance with this standard, the part that failed may be replaced. If the temperature rise of any part of the tool exceeds the temperature rise determined during the test of 12.1, forced cooling or rest periods may be applied, the rest periods being excluded from the specified operating time. If forced cooling is applied, it shall not alter the air flow of the tool or redistribute carbon deposits. During these tests, overload protection devices incorporated in the tool shall not activate. 18 Abnormal operation This clause of Part 1 is applicable, except as follows: 18.8 Replacement of Table 4 by the following: Table 4 – Required performance levels Type and purpose of SCF Minimum Performance Level (PL) Power switch  prevent unwanted switch-on a Power switch  prevent unwanted switch-on for tools where the bit does not rotate without applying axial pressure Not an SCF Power switch  provide desired switch-off a Power switch  provide desired switch-off for tools where the bit does not rotate without applying axial pressure Not an SCF Provide desired direction of rotation Not an SCF Any electronic control to pass the test of 18.3 Not an SCF Any speed limiting device Not an SCF Prevent exceeding thermal limits as in Clause 18 a 19 Mechanical hazards This clause of Part 1 is applicable, except as follows: 19.6 This subclause is not applicable. 20 Mechanical strength This clause of Part 1 is applicable, except as follows: IEC 62841-2-2:2014 © IEC 2014 20.5 This subclause is not applicable for impact wrenches with a square drive greater than or equal to 13 mm. 21 Construction This clause of Part 1 is applicable, except as follows: 21.30 This subclause is not applicable for impact wrenches with a square drive greater than or equal to 13 mm. 22 Internal wiring This clause of Part 1 is applicable. 23 Components This clause of Part 1 is applicable. 24 Supply connection and external flexible cords This clause of Part 1 is applicable, except as follows: 24.4 Replacement of paragraphs 1 and 2: For impact wrenches, the lightest cable which can be used is heavy polychloroprene sheathed flexible cable (60245 IEC 66) or equivalent. 25 Terminals for external conductors This clause of Part 1 is applicable. 26 Provision for earthing This clause of Part 1 is applicable. 27 Screws and connections This clause of Part 1 is applicable. 28 Creepage distances, clearances and distances through insulation This clause of Part 1 is applicable.

I.3 Vibration This clause of Part 1 is applicable except as follows: I.3.3.2 Location of measurement Addition: IEC 62841-2-2:2014 © IEC 2014 Annexes Annex I (informative) Measurement of noise and vibration emissions I.2.4 Installation and mounting conditions of the power tools during noise tests Impact wrenches are tested under load. The load is applied by means of a brake system, so that the socket driving the brake rotates at a test speed of (45  5) min–1 and the impact mechanism is caused to operate continuously. The brake as shown in Figure I.101 is supported on a resilient material and mounted on a bench such that the geometric centre of the tool is 1 m above the reflecting plane. The details of the brake system are given in Annex C of ISO 28927-2:2009. To prevent chattering noise from items 2, 3 and 5 of the brake shown in Figures C.1 and C.2 of ISO 28927-2:2009, these parts may be insulated between each other by material such as rubber. Figures I.102 and I.103 show the positions for different screwdrivers and impact wrenches. IEC 62841-2-2:2014 © IEC 2014 I.3.5.3 Operating conditions Addition: The operating conditions of Part 1 apply except those specified in Table I.101 and Table I.102. Table I.101 – Operating conditions for screwdrivers Orientation Screwdrivers are tested at no-load. The screwdriver is hold horizontally during the test. Tool bit Tool bit of medium length and size. Grip force Hold the machine with normal gripping force, avoiding excessive gripping force. Test cycle One test cycle is given when the tool is switched on for no load at maximum speed for more than 10 s and then switched off again. The measurement is conducted during 10 s within this period. NOTE As it is difficult to measure load applications of screwdrivers in laboratories and results have shown that the load has no influence on the vibration results, the measurements are conducted with no-load only. Table I.102 – Operating conditions for impact wrenches Orientation The tools are tested under load. Either a hexagon head bolt is screwed into a nut or a hexagon nut is screwed onto a bolt using a steel plate as part of a test fixture according to Figure I.104. The test fixture shall be either mounted on the floor or on a concrete block at least the size of the test fixture with a minimum thickness of 200 mm. NOTE Figure I.104 shows an example for mounting the test fixture. The bolts or nuts are of the biggest capacities of the tool under test. The screw case is a hard joint with one steel washer under the head. The initial setting of the bolt or nut shall provide 10 mm of exposed length from the steel plate to provide the run up. The test fixture shall not turn or move during the test. The steel plate shall be long enough to accept 5 fixings with a clearance between each fixing of at least the dimension of the head of the bolt or nut or a dimension distance which does not cause interference with the adjacent fixing. Tool bit Hex head sockets of the size and depth needed for the bolts or nuts defined above. Feed force Provide sufficient grip and feed force to maintain safe control. Avoid excessive grip and feed force. Test cycle The test cycle will be one fixing for the specified bolt or nut for a period of run down and 5 s from first impact (one test series contains five cycles). The measurement starts from switch on of the tool with the socket / bit engaged with the bolts or nuts to the end of 5 s of impact with continuous operation. This includes the time to cover run up of 10 mm. I.3.6.2 Declaration of the vibration total value Addition: The vibration total value ah of the handle with the highest emission and the uncertainty K shall be declared and: – for screwdrivers the work mode description “screw driving”; – for impact wrenches the work mode description “impact tightening of fasteners of the maximum capacity of the tool”. 1 m 1 m IEC 62841-2-2:2014 © IEC 2014 IEC 1053/14 Figure I.101 – Brake IEC 1054/14 Figure I.102 – Position of transducer for screwdrivers IEC 62841-2-2:2014 © IEC 2014 Key bolt anchor loading device (bolts or nuts, washers, steel plate) steel plate steel block (clamp) concrete block or floor steel block (support) resilient material (in the case a block is used) IEC 1055/14 Figure I.103 – Positions of transducers for impact wrenches IEC 1056/14 a) Typical example of the test fixture A A b) Loading device steel plate Figure I.104 – Test fixture options for impact wrenches IEC 62841-2-2:2014 © IEC 2014 A-A IEC 1057/14 IEC 62841-2-2:2014 © IEC 2014 Annex K (normative) Battery tools and battery packs K.1 Addition: All clauses of this Part 2-2 apply unless otherwise specified in this annex.
