21、the Joint Standards Australia/Standards New Zealand Committee EL-002- Safety of Household and Similar Electrical Appliances and Small Power Transformers to supersede in part AS/NZS 3160:2001, Approval and test specification Hand-held portable tools, 3 years from publication. During this period it is
22、 anticipated that regulatory authorities will approve chain saws to either standard. The objective of this Standard is to provide manufacturers, designers, regulatory authorities, testing laboratories and similar organizations with safety requirements designed to give the user protection against haz
23、ards that might occur during normal operation and abnormal operation of the tool and which may be used as the basis for approval for sale or for connection to the electricity supply mains in Australia and New Zealand This Standard is an adoption with national modifications and contains the full text
24、 of the second edition of IEC 60745-2-13, Hand-held motor-operated electric tools Safety Part 2- 13: Particular requirements for chain saws and has been varied as indicated to take account of Australian and New Zealand conditions. This part is to be used in conjunction with AS/NZS 60745.1:2003 and i
25、ts amendments. The Parts 2 contain clauses to supplement or modify the corresponding clauses in this part to provide the relevant requirements for each type of tool. NOTE 1 The following print types are used: requirements: in roman type; test specifications: in italic type; notes: in small roman typ
26、e. The numbering of clauses, subclauses, notes, tables, figures and annexes follows that of IEC 60745-2-13 Ed 2.0. To allow for the introduction of additional material by the IEC, the numbers 101 to 200 have been reserved. To allow for additional material to be introduced by Australia and New Zealan
27、d, the numbers 201 to 300 are used to number further clauses, subclauses, notes, tables and figures in part 1. Additional annexes are lettered ZA, ZB and so on. This scheme has been introduced to reduce the likelihood of the IEC and Australia and New Zealand using the same identifier for different p
28、urposes. The use of the word VOID indicates that the IEC text is not used in Australia or New Zealand. The use of this word also avoids the need to renumber, clauses, notes, tables and figure if an earlier clause, note, table or figure is not used. As this Standard is reproduced from an Internationa
29、l Standard, the following applies: (a) Its number does not appear on each page of text and its identity is shown on the cover and title page only. Accessed by UNIVERSITY OF SOUTH AUSTRALIA on 04 Sep 2007 5 (b) In the source text “this International Standard“ should read “this Australian/New Zealand
30、Standard“. (c) A full point substitutes for a comma when referring to a decimal marker. Variations to IEC 60745-2-13 Ed 2.0 are indicated at the appropriate places throughout this standard. Strikethrough (example) identifies IEC tables, figures and passages of text which, for the purposes of this Au
31、stralian/New Zealand standard are deleted. Where Australian/New Zealand tables, figures or passages of text are added, each is set in its proper place and identified by shading (example). Added figures are not themselves shaded, but are identified by a shaded border. Variations made to IEC 60745-2-1
32、3 Ed 2.0 form the Australian variations for the purposes of the IECEE scheme for recognition of testing to standards for safety of electrical equipment (the CB scheme). These variations have been incorporated in the body of the standard. They are listed in Annex ZZ for easy reference. The essential
