Foreword The text of the International Standard IEC 60745-2-4:2002 , prepared by SC 61F, Safety of hand-held motor-operated electric tools, of IEC TC 61, Safety of household and similar electrical appliances, together with the common modifications prepared by the Technical Committee CENELEC TC 61F, Safety of hand-held and transportable motor-operated electric tools, was submitted to the formal vote and was approved by CENELEC as EN 60745-2-4 on 2003-02-01. This European Standard supersedes EN 50144-2-4:1999 and EN 50260-2-4:2002.
The following dates were fixed:
- latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2004-02-01
- latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2006-02-01 Other standards referred to in this European standard are listed in Clause 2. Clause 2 lists the valid edition of those documents at the time of issue of this EN. This 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) 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 characteristics 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. 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 concerned. CEN/TC 255 is producing standards for non-electric sanders and polishers (EN 792-8). 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. This Part 2-4 is to be used in conjunction with EN 60745-1:2003. When this standard states "addition", "modification" or "replacement", the relevant text in Part 1 is to be adapted accordingly. Subclauses and figures which are additional to those in Part 1 are numbered starting from 101. Subclauses, tables and figures which are additional to those in IEC 60745-2-4 are prefixed “Z”. NOTE In this standard, the following print types are used: - requirements: in roman type; - test specifications: in italic type; - notes: in smaller roman type.

COMMON MODIFICATIONS 1 Scope Replace the first paragraph of the addition by: This standard applies to sanders and polishers with the exception of all types of rotating disc-type sanders, which are covered by EN 60745-2-3.
NOTE Until publication of EN 60745-2-3, rotating disc-type sanders are covered by EN 50144-2-3. 6 Void Replace by: 6 Environmental requirements This clause of Part 1 is applicable except as follows: 6.1.2.4 Modification: Sanders and polishers are suspended. The plate of the tool shall be horizontal. 6.1.2.5 Modification: Sanders and polishers are tested at no-load. 6.2.2.4 Modification: Sanders and polishers are tested under load observing the conditions shown in Tables Z101 and Z102. Table Z101 - Test conditions for sanders Orientation Sanding a horizontal steel plate 400 mm × 400 mm × 20 mm mounted on a bench Tool bit Recommended sanding paper for steel with a grain size of 180 Feed force 50 N ± 5 N Pre-test requirements With a new sanding sheet carry out 1 min sanding before starting measurements

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
