31、MENT 1 AMENDEMENT 1 2 60745-2-1 Amend. 1 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 the followi

32、ng documents: FDIS Report on voting 61F/731/FDIS 61F/751/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 IEC 60745-1,

33、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 and the addition of a new safety warning to Clause 8: Marking and instructions. The committee has decided that the contents of thi

34、s 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 At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or am

35、ended. _ 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 drills and impact drills. 3 Definitions Change the title of Clause 3 to read: 3 Terms and definitions 8 Marking and instructions Replace

36、 the existing text of 8.12.1 by the following: Amendment 1:2010 to CAN/CSA-C22.2 No. 60745-2-1-0460745-2-1 Amend. 1 IEC:2008 3 8.12.1.1 Addition: Drill safety warnings Wear ear protectors when impact drilling. Exposure to noise can cause hearing loss. NOTE The above warning applies only to impact dr

37、ills and may be omitted for drills other than impact drills. 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 co

38、rd. Cutting accessory contacting a “live“ wire may make exposed metal parts of the power tool “live“ and could give the operator an electric shock. 12 Heating Replace the existing text of 12.3 by the following: 12.3 Addition: The temperature-rise limit specified for the external enclosure does not a

39、pply to the enclosure of the impact mechanism. 17 Endurance Replace the existing text of 17.2 by the following: 17.2 Replacement for impact drills: Impact drills are operated with no load and, if the impact mechanism can be engaged and disengaged at will, the impact mechanism shall remain disengaged

40、, for 12 h at supply voltage equal to 1,1 times rated voltage and then for 12 h at a supply voltage equal to 0,9 times rated voltage. The speed is adjusted to the highest value of the highest range. Each cycle of operation comprises an “on” period of 100 s and an “off” period of 20 s, the off period

41、s 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. During this test, replacement of the carbon brushes is allowed, and the tool is oiled and greased as in

42、normal use. The tool may be switched on and off by means of a switch other than that incorporated in the tool. The impact drills are then mounted vertically in a test apparatus as shown in Figure 101 and are operated at rated voltage or at the mean value of the rated voltage range, for four periods

43、of 6 h each, the interval between these periods being at least 30 min; if the impact mechanism can be engaged and disengaged at will, the impact mechanism shall remain engaged. During these tests, the impact drills are operated intermittently, each cycle comprising a period of operation of 30 s and

44、a rest period of 90 s during which the tool remains switched off. During the tests, an axial force, just enough to ensure steady operation of the impact mechanism, is applied to the impact drill through a resilient medium. Amendment 1:2010 to CAN/CSA-C22.2 No. 60745-2-1-04 4 60745-2-1 Amend. 1 IEC:2

45、008 If the impact mechanism fails mechanically during the test without causing an accessible part to become live, it may be replaced by a new one. During these tests, overload protection devices shall not operate. NOTE 1 Monitoring of external temperatures will help avoid mechanical failures. NOTE 2

46、 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. 21 Construction Replace the existing text of 21.18 by the following: 21.18 Addition: A switch lock-on device, if

47、 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 while the index finger of

48、 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 device within the grasping area, the lock-on device shall not be actuated by a straight-edged utensil when the utensil is made to pass back and forth ac

49、ross the device in any direction. The straight-edged utensil may be of any convenient length sufficient to bridge the surface of the lock-on device and any surface adjacent to the lock-on device. 23 Components Replace the existing text of Clause 23 by the following: This clause of Part 1 is applicable, except as follows: 23.3 Replacement: Overloa
