The text of the draft was submitted to the Unique Acceptance Procedure (UAP) in December 1993 and was approved by CENELEC as EN 50144-2-10 on1994-10-04.A draft for an amendment was submitted to UAP in April 1994 and was approved by CENELEC on1994-10-04 for inclusion into the European Standard.A further amendment was submitted to UAP in May 1996 and was approved by CENELEC as amendment A1 to EN 50144-2-10 on 1996-12-09.Amendments to fulfill the essential requirements of the Machinery Directive were submitted to the formal vote in June 1998 and were approved by CENELEC on 1998-10-01 for inclusion, together with the earlier amendment, into a second edition of EN 50144-2-10.This European Standard supersedes EN 50144-2-10:1996. The following dates were fixed:-latest date by which the EN has to be implemented at a national level by publication of an identicalnational standard or by endorsement(dop)2001-09-01-latest date by which the national standards conflictingwith the EN have to be withdrawn (dow)2001-12-01This standard is divided into two parts:Part 1: General requirements which are common to most hand-held electric motor operated tools (for the purpose of this standard referred to simply as tools).Part 2: Requirements for particular types of tool which either supplement or modify the requirements given in Part 1 to account for the particular hazards and characteristics of these specific tools.This European Standard has been prepared under a mandate given to CEN/CENELEC by the European Commission and the European Free Trade Association and supports the essential health and safety requirements of the Machinery Directive.Compliance 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.For noise and vibration this standard covers the requirements for their measurement, the provision of information arising from these measurements and the provision of information about the personal protective equipment required. Specific requirements for the reduction of the risk arising from noise and vibration through the design of the tool are not given as this reflects the current state of the art.As with any standard, technical progress will be kept under review so that any developments can be taken into account.CEN TC/255 is producing standards for non-electrically powered tools.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 292-1 and EN 292-2.Subclauses, tables and figures which are additional to those in Part 1 are numbered starting from 101.NOTE In this European Standard the following print types are used:- Requirements proper;- Test specifications;- Explanatory matter.Licensed Copy: Institute Of Technology Tallaght, Institute of Technology, Tue May 08 12:24:35 GMT+00:00 2007, Uncontrolled Copy, (c) BSIContents1Scope. 42Definitions . 43General requirements. 44General conditions for the tests . 45Rating . 46Classification . 47Marking and information for use . 58Protection against electric shock . 59Starting . 510Input and current . 511Heating . 512Leakage current . 513Environmental requirements. 614Moisture resistance . 715Insulation resistance and electric strength . 716Endurance. 717Abnormal operation . 718Mechanical hazards. 719Mechanical strength . 720Construction . 721Components. 722Internal wiring. 723Supply connection and external flexible cables and cords . 724Terminals for external conductors . 825Provision for earthing . 826Screws and connections . 827Creepage distances, clearances and distances through insulation . 828Resistance to heat, fire and tracking. 829Resistance to rusting . 830Radiation. 8Annexes. 11Licensed Copy: Institute Of Technology Tallaght, Institute of Technology, Tue May 08 12:24:35 GMT+00:00 2007, Uncontrolled Copy, (c) BSI1ScopeThis clause of Part 1 is applicable except as follows:Addition:This European Standard applies to jig saws.It does not apply to sabre saws which are covered by EN 50144-2-11.This standard does not give requirements for the design of the tool for the reduction of the risk arising from noise and vibration.2DefinitionsThis clause of Part 1 is applicable except as follows:2.2.18Addition:normal load for jig saws intended to cut wood: The load obtained when the saw is operated continuously with the saw blade in the vertical position, the load being such that the input, in watts, is equal to:0,1 snwhere s is the maximum cutting depth, in millimetres, marked on the saw, and n is the number of reciprocations per minute under no load conditions as marked on the saw.3General requirementsThis clause of Part 1 is applicable.4General conditions for the testsThis clause of Part 1 is applicable except as follows:4.10Addition:For tests carried out under normal load, the reciprocating mechanism may be replaced by a rotating gear, so that the jig saw can be loaded by means of a brake.5RatingThis clause of Part 1 is applicable.6ClassificationThis clause of Part 1 is applicable.Licensed Copy: Institute Of Technology Tallaght, Institute of Technology, Tue May 08 12:24:35 GMT+00:00 2007, Uncontrolled Copy, (c) BSI7Marking and information for useThis clause of Part 1 is applicable except as follows:7.1Addition:Jig saws intended to cut wood shall be marked with: maximum cutting depth in millimetres, number of reciprocations per minute under no load conditions.The number of reciprocations under no load conditions determined after the jig saw has been running idle for 10 min at rated voltage or at the upper limit of the rated voltage range.7.13.1Addition: information on the correct use of the dust collection equipment, if fitted;8Protection against electric shockThis clause of Part 1 is applicable.9StartingThis clause of Part 1 is applicable.10Input and currentThis c
