3、ganization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been establ
4、ished has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardizati
5、on. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS0 10517 was prepared by Technical Committee

9、 requirements and tests 1 Scope This International Standard presents definitions of terms, and specifies safety requirements and test procedures applicable to portable hand-held powered hedge trimmers which are primarily designed for cut- ting hedges and bushes using one or more linear reciprocating
10、 cutter blades. It does not apply to hedge trimmers with rotating blades. For different types of machines, see figure 1 a) and b) showing two internal combustion engine-driven hedge trimmers and figure 1 c) for an electrical-driven hedge trimmer. The electrical aspects of electrical powered hedge tr
11、immers are not covered by this International Stan- dard. See IEC 745-2-l 5. 3 Definitions For the purposes of this International Standard, the following definitions apply. 3.1 blade tooth: That part of the cutter blade which is sharpened or has sharp edges to perform the shearing action. 3.2 cutter
12、blade: Part of the cutting device having blade teeth which cut by shearing action either against other blade teeth or against an unsharpened shear plate. 3.3 cutting device: Exposed part of the assembly of cutter blade and unsharpened shear plate, or the cutting blades together with any supporting p
13、art, which perform the cutting action. 3.4 front handle: Support handle located at or to- wards the cutting device. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publi- cat
14、ion, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most re- cent editions of the standards indicated below. Members of IEC and IS0 maintain registe
15、rs of cur- rently valid International Standards. IEC 745-l :1982, Safety of hand-held motor-operated electric too/s - Part 7: General requirements.

If
22、 a part containing the motor is suitably shaped it may be considered as a handle. The handles shall be designed in such a way that each one can be grasped completely with one hand. The gripping surface shall be at least 100 mm long (for an example, see figure 7) and there shall be 25 mm radial clear
23、ance around the gripping length. On bail or closed handles (U-shaped handles) this dimension is related to the inner width of the gripping surface. On straight handles it is the complete length between the hous- ing and the end of the handle. Adjustable handles shall be positively located. If they a
24、re adjustable in different positions it shall not be possible to lock them in a position not complying with the safety requirements, If a handle is supplied unassembled from the ma- chine, it shall not be possible to assemble it without any necessary guard being properly in place. Compliance shall b
25、e checked by inspection and measurement. 4.2 Hand protection 4.2.1 Requirement With both hands on the handles, it shall not be poss- ible to touch the moving cutter blade with fingers spread out. 4.2.2 Test method The requirement in 4.2.1 is met if both handles are located so that the test distance
26、from the cutter blade to the side of either handle furthest from the cutter blade is not less than 120 mm. This distance shall be measured along the shortest paths from the furthest side of the handle to the cutter blade see figure3aI-J and, if there is a guard, from the furthest side of the handle
27、to the guard and from here to the nearest cutting edge of the cutter blade see figure 3 b). 4.2.3 Cutting device requirement Hedge trimmers shall be so designed that injury to the operator, from the cutting device, is reduced as far as practical. This requirement is met if the requirements of table
28、1 and figures 4 to 6 are met. 3 Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=NASA Technical Standards 1/9972545001 Not for Resale, 04/23/2007 21:41:53 MDTNo reproduction or networking permitted without license from IHS -,-,- IS0 10517:1993(

The manufacturer may be
35、requested to furnish proof to the certification authority that the mechanism has satisfied tests to meet this requirement, Such tests shall consist of a minimum of 2 500 on/off cycles from maximum speed. 4.5 Balance of machine for transport 4.5.1 Requirement The angle measured in accordance with 4.5
36、.2 shall be between -45” and +45”. This requirement applies only to those machines having a holding moment greater than 20 N*m where there is a transport han- dle. 4.5.2 Test method With the tanks needed for operation half-full, suspend the machine from the transport handle at the point giving the b
37、est lateral balance. Measure the angle between the centreline of the cutting device and the horizontal plane. 4.6 Transport guard A transport guard shall be provided. It shall be durable and cover the cutting device during transportation or when the hedge trimmer is stored. The guard shall stay in i
38、ts protective position when holding the covered cutting device downwards. 5 Starting and idling The hedge trimmer shall be so designed that two separate and dissimilar actions are required before the cutting means starts to move. The provision of two switches in separate handles does not satisfy thi
39、s re- quirement unless their methods of operation are dif- ferent. Starting the engine shall not be considered as one of these actions unless the engine stops when the control is released. On internal combustion engine-driven hedge trimmers, there shall be a means which separates the driving mechani
40、sm from the cutting blades. When starting and when the engine is idling, the cutting device shall not have any cutting action. This requirement shall be checked by inspection. When starting the engine of machines, the throttle trigger may be locked in a starting position. This pos- ition shall be ca
41、ncelled automatically when the throttle trigger is operated. If a centrifugal clutch is provided, it shall stop the power to the cutting blades when the engine is idling. This requirement is met if the cutting device disengages at not less than 1,3 times the idling speed. 6 Blade control With the ha
42、nds on the handles, it shall be easy to operate the control from all normal positions of the hands, without having to move the position of either hand. Release of the control shall cause the cutting device to stop. This requirement shall be checked by inspection, 7 Engine stop Internal combustion en
43、gine-driven hedge trimmers shall have an on/off control which may be operated without releasing hold of either of ?% handles. The engine-stopping device shall not depend on sustained manual pressure for its operation. The stop position shall be clearly marked. 8 Moving parts protection All moving pa
44、rts other than the cutting device shall be guarded to prevent the operator s contact with these components. This requirement shall be checked by using the IEC finger probe (see IEC 745-l). 9 Heat protection 9.1 Requirements A guard or shield shall be provided to prevent inad- vertent contact with an
45、y exposed engine exhaust component larger than 10 cm2 and with a surface hotter than 80 “C, measured at (20 f 3) “C ambient temperature, during normal starting and operation of the machine. Handles and permanently held controls shall not ex- ceed 45 “C measured at (20 f 3) “C ambient tem- perature.
46、Other controls contacted during normal operation shall not exceed 55 “C measured at (20 + 3) “C ambient temperature. 9.2 Test method Conduct the test in the shade. Lubricate as rec- ommended by the manufacturer. Operate the engine at its maximum no-load speed until the temperature stabilizes. Determ
47、ine temperatures by correcting the observed temperature by the difference between the specified ambient and the test ambient temperature. 7 Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=NASA Technical Standards 1/9972545001 Not for Resale, 0
