15、anization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of the 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 activi

16、ties, the IEC publishes International Standards. 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

17、 participate in this preparation. The 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 the IEC on technical matters express, as nearly a

18、s possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested National Committees. 3) The documents produced have the form of recommendations for international use and are published in the form of standards, technical

19、 specifications, technical reports or guides and they are accepted by the National Committees in that sense. 4) In order to promote international unification, IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent possible in their national and reg

20、ional standards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter. 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity w

21、ith one of its standards. 6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61029-2-11 has been prepare

22、d by subcommittee 61F: Safety of hand-held motor-operated electric tools, of IEC technical committee 61: Safety of household and similar electric appliances.

The portion of the blade not performing chopping action shall

45、 be completely enclosed by the guarding system (i.e. bench saw guard, rip fence). The remaining portion of the blade shall be fitted with a movable guard which covers the blade teeth on both sides of the blade and shall return automatically to its rest position when the blade is withdrawn from the w

46、orkpiece. The guard shall comply with the above at any mitre and bevel position in which the saw can be used. The movable guard shall be of a U-shaped construction, which completely encloses the blade (figure 101); of an open construction, which so protects both sides of the saw blade teeth (figure

47、102). Compliance is checked by applying in any possible position the rigid test probe of figure 103.61029-2-11 IEC:2001(E) 9 In both cases, the movable guard shall protect at least the portion of the blade in front of the fence F (figures 101 and 102). It shall not be possible to lift the guard by h

48、and when the saw is in the rest position. Compliance is checked by the following test. The movable guard shall be loaded by a force of 100 N perpendicular to the lower table and through the axis of the blade. Access to the blade teeth shall not be possible using the test probe of figure 103. 18.1.10

49、1.2 Bench mode Saws shall have a guard above the upper table for the crown and the front of the saw blade which may be an adjustable guard, an automatic guard or a combination of these. This guard shall be designed to encompass the saw blade when it is set in its highest position in the table (figure 110). The guard shall be constructed of material (for example, aluminium, wood, plastic) which will minimize damage to the saw blade
