12、DE PRIXAMENDMENT 2 AMENDEMENT 2 2 60745-2-6 Amend. 2 IEC:2008 FOREWORD This amendment has been prepared by subcommittee 61F: Safety of hand-held motor-operated electric tools, of IEC technical committee 61: Safety of household and similar electrical appliances. The text of this amendment is based on

13、 the following documents: FDIS Report on voting 61F/734/FDIS 61F/754/RVD Full information on the voting for the approval of this amendment can be found in the report on voting indicated in the above table. With this amendment, this Part 2 is established on the basis of the fourth edition (2006) of I

14、EC 60745-1, Hand-held motor-operated electric tools Safety Part 1: General requirements. Main changes include editorial modifications to match with the fourth edition of IEC 60745-1, addition of a new safety warning to Clause 8: Marking and instructions, and clarifications in Annex K. The committee

15、has decided that the contents of this amendment and the base publication will remain unchanged until the maintenance result date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn,

16、replaced by a revised edition, or amended. _ 1 Scope Replace the existing text of Clause 1 by the following: This clause of Part 1 is applicable, except as follows: Addition: This standard applies to hammers. Tools covered by this standard include but are not limited to percussion and rotary hammers

Amendment 2:2009 to CAN/CSA-C22.2 No. 60745-2-6-0460745-2-6 Amend. 2 IEC:2008 3 3 Definitions Change the title of Clause 3 to read: 3 Terms and definitions 8 Marking and instructions Replace the existing text of 8.12.1 by the following: 8.12.1.1 Addition: Hammer safety warnings Wear ear protectors

18、. Exposure to noise can cause hearing loss. Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury. Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting acces

19、sory contacting a “live“ wire may make exposed metal parts of the power tool “live“ and could give the operator an electric shock. 20 Mechanical strength Replace the existing text of 20.3 by the following: 20.3 Replacement: Hammers up to 10 kg shall withstand being dropped three times in total on a

20、concrete surface from a height of 1 m. For these three drops, the sample shall be tested in the three most unfavourable positions and the lowest point of the tool shall be 1 m above the concrete surface. For the test, separable accessories are not mounted. Hammers exceeding 10 kg are subjected to th

21、ree impacts that result from the tool being tipped over to strike a concrete surface. The tool is tipped with the longest accessory recommended by the manufacturer except when the recommended accessory is longer than 1 m. In this case, the tools are tested with a 1 m accessory. The tool is positione

22、d in an upright position with the tip of the accessory resting on a concrete surface. The tool is then tipped in three different directions on to the concrete surface. Add the following subclause: 20.5 Replacement: Hammers are regarded as tools that are likely to cut into concealed wiring or their o

23、wn cord. Therefore, handles and grasping surfaces, as specified in the instruction manual, shall have adequate mechanical strength in order to provide insulation between the grasping area and the output shaft.

24、e is checked by the following test: A separate sample, at the discretion of the manufacturer, is to be subjected to a single impact on each handle and each recommended grasping surface. For hammers up to 10 kg, the impacts are carried out from a height of 1 m onto a concrete surface. For hammers exc

25、eeding 10 kg, the impacts are carried out by tipping the tool over to strike the concrete surface. The tool is tipped with the longest accessory recommended by the manufacturer except when the recommended accessory is longer than 1 m. In this case, the tool is tested with a 1 m accessory. The impact

26、s are followed by an electric strength test according to Clause 15 using 1 250 V a.c. between the grasping surfaces in contact with foil and the output shaft of the tool. 21 Construction Replace the existing text of 21.18 by the following: 21.18 Addition: Percussion hammers and rotary hammers operat

27、ing in the percussion mode may have a switch with a locking arrangement to lock it in the “on” position. For these tools, the switch shall unlock automatically with a single motion without releasing the grasp on the tool. Compliance is checked by inspection and by a manual test. For rotary hammers,

28、a switch lock-on device, if any, shall be located outside the grasping area or so designed that it is not likely to be unintentionally locked on by the users hand during intended left- or right-handed operation. This grasping area is considered to be the contact area between either hand and the tool

29、 while the index finger of that hand is resting on the switch actuator of the tool. Compliance is checked by inspection or by the following test. For a switch with a lock-on button device within the grasping area, the lock-on device shall not be actuated by a straight-edged utensil when the utensil

30、is made to pass back and forth across the device in any direction. The straight edge of the utensil shall be of sufficient length to bridge the surface of the lock-on device and any surface adjacent to the lock-on device.

K.8.12.1.1 Replacement of this subclause of Part 2: Wear ear protectors. Exposure to

32、noise can cause hearing loss. Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury. Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring. Cutting accessory contacting a “live“ wire

33、may make exposed metal parts of the power tool “live“ and could give the operator an electric shock. K.12.4 This subclause of Part 2 is not applicable.
