Part 2-11: Particular requirements for hand-held reciprocating saws FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of 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 activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). 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 participate in this preparation. 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 IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62841-2-11 has been prepared by IEC technical committee 116: Safety of motor-operated electric tools. The text of this standard is based on the following documents: FDIS Report on voting 116/246/FDIS 116/256/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. This Part 2-11 is to be used in conjunction with the first edition of IEC 62841-1 (2014). This Part 2-11 supplements or modifies the corresponding clauses in IEC 62841-1, so as to convert it into the IEC standard: Particular requirements for hand-held reciprocating saws. Where a particular subclause of Part 1 is not mentioned in this Part 2-11, that subclause applies as far as relevant. Where this standard states “addition”, “modification” or “replacement”, the relevant text in Part 1 is to be adapted accordingly. The following print types are used: – requirements: in roman type; – test specifications: in italic type; – notes: in small roman type. The terms defined in Clause 3 are printed in bold typeface. Subclauses, notes and figures which are additional to those in Part 1 are numbered starting from 101. A list of all parts of the IEC 62841 series, under the general title: Electric motor-operated hand-held tools, transportable tools and lawn and garden machinery – Safety, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website 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 • amended. NOTE The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the recommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 36 months from the date of publication.

The downward force applied to the tool shall not exceed the force to ensure contact of the base plate with the workpiece by more than 30 N. The feed force and the downward force shall be determined e.g. by means of a scale and shall be recorded. Test cycle Cutting off an approximately 8 mm wide strip across the 100 mm width of the metal sheet. Measurement starts when the saw blade enters the metal sheet and stops when the saw blade leaves the metal sheet. Table I.103 – Test conditions for sabre saws cutting wooden beams Orientation Cutting a horizontal beam of construction wood such as fir with a cross-section of (100 ± 5) mm × (100 ± 5) mm and a minimum length of 500 mm. The beam shall be supported on resilient material and fixed by screws, clamps, air cylinders or the like to a test rig, see Figure I.102. In all cases, the beam excess end shall be approximately 250 mm from the clamp and shall be readjusted at the beginning of each series of tests, which consists of five test cycles. During the test, the operator may use swivel action to allow proper chip ejection. Tool bit/settings New saw blade for the entire series of tests as specified for sawing large wooden beams. The saw blade used shall be recorded. Pendulum systems, if any, being set as specified by the manufacturer for cutting wooden beams. If not specified by the manufacturer, pendulum systems are set to maximum. The guide plate shall be fitted. Feed force The vertical feed force (force in direction of the cut) applied to the tool in addition to its weight shall be (40 ± 5) N. Excessive gripping force shall be avoided. The horizontal force applied to the tool shall not exceed the force to ensure contact of the guide plate with the workpiece by more than 30 N. The feed force and the horizontal force shall be determined e.g. by means of a scale and shall be recorded. Test cycle Cutting off an approximately 30 mm thick slice. Measurement starts when the saw blade enters the wood and stops when the saw blade leaves the wood. I.3.6.1 Reported vibration value Replacement: Three series of five consecutive tests shall be carried out using a different operator for each series. If it can be shown that the vibration is not affected by operator characteristics, it is acceptable to perform all 15 measurements with one operator only. The measurements are made in three axes and the results of each direction shall be combined using formula (I.3) to obtain the vibration total value ahv. The measurement result ah shall be determined as the arithmetic mean of vibration total values over the tests and operators. For jig saws, the results ah for two operation modes shall be reported: – ah,B = mean vibration “cutting board” in accordance with Table I.101. – ah,M = mean vibration “cutting sheet metal” in accordance Table I.102. For sabre saws, the results ah for two operation modes shall be reported: – ah,B = mean vibration “cutting board” in accordance with Table I.101. – ah,WB = mean vibration “cutting wooden beam” in accordance Table I.103. I.3.6.2 Declaration of the vibration total value Addition: The vibration total value of the handle with the highest emission and the uncertainty K shall be declared together with the saw blade used: – for jig saws the value of ah,B, with the work mode description “cutting boards with saw blade …” and the value of ah,M, with the work mode description “cutting sheet metal with saw blade …”; − for sabre saws the value of ah,B, with the work mode description “cutting boards with saw blade …” and the value of ah,WB, with the work mode description “cutting wooden beams with saw blade …”. NOTE The saw blade significantly influences the vibration behaviour. Therefore the combination of the vibration value along with the saw blade used for the test provides important information.
