14、ical Committee CENELEC TC 61F (transformed into TC 116), was submitted to the formal vote and was approved by CENELEC as EN 60745-2-6 on 2003-02-01. A number of amendments to EN 60745-2-6 have since been voted on and published as amendments A1, A11, A2 and A12. A further draft amendment (FprAD) incl
15、uding improvements to the vibration test code was submitted to the Unique Acceptance Procedure. The combined texts were approved by CENELEC as a new edition of EN 60745-2-6 on 2010-02-01.

17、lication of an identical national standard or by endorsement (dop) 2011-02-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2013-02-01 This standard is divided into two parts: Part 1: General requirements which are common to most hand-held electric mo
18、tor-operated tools (for the purpose of this standard referred to simply as tools) which could come within the scope of this standard; Part 2: Requirements for particular types of tools which either supplement or modify the requirements given in Part 1 to account for the particular hazards and charac
19、teristics of these specific tools. This European Standard has been prepared under a mandate given to CEN and CENELEC by the European Commission and the European Free Trade Association and supports the essential health and safety requirements of the Machinery Directive 2006/42/EC. See Annex ZZ. Compl
20、iance with the clauses of Part 1 together with this Part 2 provides one means of conforming with the essential health and safety requirements of the Directive concerned. CEN/TC 255 is producing standards for non-electric rotary percussive drills (EN 792-5) and non-rotary percussive power tools (EN 7
21、92-4). Warning: Other requirements and other EC Directives can be applicable to the products falling within the scope of this standard. This standard follows the overall requirements of EN ISO 12100-1 and EN ISO 12100-2. This Part 2-6 is to be used in conjunction with EN 60745-1:2009. When this stan
22、dard states “addition“, “modification“ or “replacement“, the relevant text in Part 1 is to be adapted accordingly.

30、 BS EN 60745-2-6:2010EN 60745-2-6:2010 (E)The sound power level shall be measured according to EN ISO 3744, where the acoustic environment, instrumentation, quantities to be measured, quantities to be determined, and the measurement procedure are specified. The sound power level shall be given as A-
31、weighted sound power level in dB reference 1 pW. The A-weighted sound pressure levels, from which the sound power is to be determined, should be measured directly, and not calculated from frequency band data. Measurements shall be made in an essentially free field over a reflecting plane. The sound
32、power level shall be determined by using a hemispherical measurement surface according to Figure Z101. The location of the six microphone positions distributed on the surface of the hemisphere of radius r are listed in the form of Cartesian coordinates in Table Z101. Table Z101 Coordinates of the si
33、x microphone positions Number of microphone x/r y/r Mass of equipment 3,5 5 5 7 7 10 10 18 18 Diameter of drill bit mm 10 16 20 25 32 40 Usable length of drill bit mm 80 200 250 Depth of hole mm 80 180 180Table Z104 Noise test conditions for rotary hammers Orientation Drilling vertically down into a
34、 concrete block having the formulation specified in Table Z102 and having the minimum dimensions 500 mm x 500 mm and 200 mm in height and supported on resilient material. The concrete block, its support and the tool shall be so oriented that the geometric centre of the tool is 1 m above the reflecti
35、ng plane. The centre of the concrete block shall be located under the top microphone. Tool bit New drill bit as recommended by the manufacturer for drilling in concrete and of the size defined in Table Z103. Feed force The feed force applied to the tool in addition to its weight shall be sufficient
36、to ensure stable operation with good performance. Test cycle Measurement starts, when the drill bit has reached a depth equal to its diameter, and stops, when the depth of hole according to Table Z103 has been reached and before the drill bit is removed from the hole. NOTE 1 In general, stable opera
37、tion with good performance is achieved by increasing the feed force by 30 N after the hammer has stopped bouncing and is operating smoothly. NOTE 2 For consistency of results the drilled holes should be blind holes. If the drill bit breaks through, the depth of the hole may be reduced slightly to av
38、oid this. 9 BS EN 60745-2-6:2010EN 60745-2-6:2010 (E)6.2.4.2 Location of measurement Addition: Figures Z107 and Z108 show the transducer positions for different types of hammers. 6.2.6.3 Operating conditions Addition: If rotary hammers have a chiselling (non rotary) function, they shall be tested in
39、 the chiselling and rotary hammer function according to 6.2.6.3.101 and 6.2.6.3.102. During the test, an auxiliary handle (front handle) shall be mounted in a 90 angle to the machine (Figures Z107 and Z108 show the handle in 0 position). 6.2.6.3.101 Percussion hammers without rotary action (concrete
40、 breakers and picks, chiselling hammers) For hammers without rotary action all speed setting devices shall be adjusted to the highest value. Hammers without rotary action are tested under load in the loading device shown in Figure Z104 and described in 6.1.2.5.102 and in accordance with the conditio
41、ns shown in Table Z105. Table Z105 Vibration test conditions for hammers without rotary action Orientation Operating vertically in the loading device which is mounted on a concrete block having the minimum dimensions specified in Table Z104. To avoid negative effects on the measurement results, the
42、inserted tool shall be aligned in the middle of the bushing without contact to the bushing. Tool bit Test tool as shown in Figure Z104, item 1. Feed force The feed force applied to the tool in addition to its weight shall be sufficient to ensure stable operation with good performance. Excessive grip
43、 force shall be avoided. To allow correct operation, vibration reducing mechanisms shall not be overloaded. NOTE In general, stable operation with good performance is achieved by increasing the feed force by 30 N after the hammer has stopped bouncing and is operating smoothly. In addition, hammers w
44、ithout rotary action are tested under “no load”, by lifting the hammer up so that its weight is totally supported by the hands of the operator whilst the inserted tool is still located in the loading device and the hammer. During the measurement, the loading device shall not exert any force to the i
45、nserted tool which could influence the measurement. 6.2.6.3.102 Rotary hammers For rotary hammers the speed setting shall be that recommended by the manufacturer for the drill bit size defined for the test for drilling in concrete. Hammers with rotary action are tested under load as shown in Figure
46、Z106 and in accordance with the conditions shown in Tables Z102, Z103 and Z106. 10 BS EN 60745-2-6:2010EN 60745-2-6:2010 (E)Table Z106 Vibration test conditions for rotary hammers Orientation Drilling vertically down into a concrete block having the formulation specified in Table Z102 and having the
47、 minimum dimensions 500 mm x 500 mm and 200 mm in height and supported on resilient material. Tool bit New drill bit as recommended by the manufacturer for drilling in concrete and of the size defined in Table Z103. Feed force The feed force applied to the tool in addition to its weight shall be suf
48、ficient to ensure stable operation with good performance. Excessive grip force shall be avoided. To allow correct operation, vibration reducing mechanisms shall not be overloaded. Test cycle Measurement starts, when the drill bit has contact to the concrete block and stops, when the depth of the hol
49、e according to Table Z103 has been reached and before the drill bit is removed from the hole. NOTE 1 In general, stable operation with good performance is achieved by increasing the feed force by 30 N after the hammer has stopped bouncing and is operating smoothly. NOTE 2 For consistency of results the drilled holes should be blind holes. If the drill bit breaks through, the depth of the hole may be reduced slightly to avoid this. 6.2.7.1 Reported vibration value Addition: If more than one operatin
