14、EC/TC 61, “Safety of household and similar electrical appliances“ was submitted to the IEC-CENELEC parallel vote and approved by CENELEC as EN 60335-2-72:2012. A draft amendment, which covers common modifications to IEC 60335-2-72, was prepared by CLC/TC 61, “Safety of household and similar electric
15、al appliances“ and approved by CENELEC. The following dates are fixed: latest date by which this document has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2013-05-03 latest date by which the national standards conflicting with this docu
16、ment have to be withdrawn (dow) 2015-05-03 This document supersedes EN 60335-2-72:2009. The principal changes in EN 60335-2-72:2012 as compared with EN 60335-2-72:2009 are as follows (minor changes are not listed): the title has been changed for better distinction with regard to EN 60335-2-67; the s
17、cope has been revised editorially to avoid misunderstandings; Clause 3 has been revised with regard to the requirements revised; the standard has been revised in general and updated regarding state-of-the-art, as far as necessary, in particular some changes have been made to Clauses 15, 22, and 25;
18、the markings and instructions (Clause 7) have been revised basically; a new Annex DD Emission of acoustical noise was added; and a new Annex EE Emission of vibration was added. This part 2 is to be used in conjunction with the EN 60335-1:2012 and its amendments. NOTE 1 When “Part 1” is mentioned in
19、this standard, it refers to EN 60335-1. This part 2 supplements or modifies the corresponding clauses in EN 60335-1, so as to convert that publication into the European Standard: Safety requirements for floor treatment machines with or without traction drive, for commercial use. When a particular su
20、bclause of Part 1 is not mentioned in this part 2, that subclause applies as far as is reasonable. When this standard states “addition”, “modification” or “replacement”, the relevant text in Part 1 is to be adapted accordingly. NOTE 2 The following numbering system is used: subclauses, tables and fi
21、gures that are numbered starting from 101 are additional to those in Part 1; unless notes are in a new subclause or involve notes in Part 1, they are numbered starting from 101, including those in a replaced clause or subclause; additional annexes are lettered AA, BB, etc. NOTE 3 The following print
22、 types are used: BS EN 60335-2-72:2012 EN 60335-2-72:2012 (E) 2 requirements: in roman type; test specifications: in italic type; notes: in small roman type. Words in bold in the text are defined in Clause 3. When a definition concerns an adjective, the adjective and the associated noun are also in
23、bold. Clauses, subclauses, notes, tables, figures and annexes which are additional to those in IEC 60335-2-72:2012 are prefixed “Z”. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CENELEC and/or CEN shall not be held responsible
24、for identifying any or all such patent rights.
