4、.S.W. Review of Australian Standards. To keep abreast of progress in industry, Australian Standards are subject to periodic review and are kept up to date by the issue of amendments or new editions as necessary. It is important therefore that Standards users ensure that they are in possession of the
5、 latest edition, and any amendments thereto. Full details of all Australian Standards and related publications will be found in the Standards Australia Catalogue of Publications; this information is supplemented each month by the magazine The Australian Standard, which subscribing members receive, a
6、nd which gives details of new publications, new editions and amendments, and of withdrawn Standards. Suggestions for improvements to Australian Standards, addressed to the head office of Standards Australia, are welcomed. Notificationof any inaccuracy or ambiguity found in an Australian Standard sho
7、uld be made without delay in order that the matter may be investigated and appropriate action taken.

9、ind and hand-held lawn trimmers and lawn edge trimmersMechanical safety requirements and test methods. Of the organizations represented on the Committee, the Australian Federation of Consumer Organizations did not agree to the publication of this Standard. The Australian Federation of Consumer Organ
10、izations had concerns about the battery stowage requirements, the marking of controls and the determinationof the permissible kinetic energy of the cutting element. Under arrangements made between Standards Australia and the InternationalStandards bodies, ISO and IEC, as well as certain other Standa
11、rdsorganizations, users of this Australian Standard are advised of the following: (a) Copyright is vested in Standards Australia. (b) The numberof this Standard is not reproduced on each page;its identityis shown only on the cover and title pages. (c)There may be occasionaldual languagesections, but
12、 English is always one of the languages reproduced. (d) Where any cross-references to page numbers appear within the test, these relate to page numbering in the InternationalStandard and are to be disregarded. For the purpose of this Australian Standard, the ISO text should be modified as follows: (
13、i)Substitute a full point for a comma as a decimal point. (ii) Replace the reference to another publication with reference to an Australian Standard as follows: Reference to International StandardAustralian Standard IEC 335Safetyofhouseholdandsimilar electrical appliances AS 335.1Part 1: General req

Standards Australia will permit up to 10 percent of the technical content pages of a Standard to be copied for use
18、 exclusively in-house by purchasers of the Standard without payment of a royalty or advice to Standards Australia. Standards Australia will also permit the inclusion of its copyright material in computer software programs for no royalty payment provided such programs are used exclusively in-house by
19、 the creators of the programs. Care should be taken to ensure that material used is from the current edition of the Standard and that it is updated whenever the Standard is amended or revised. The number and date of the Standard should therefore be clearly identified. The use of material in print fo
