No.DateComments National foreword This British Standard is the official English language version of EN 60335-2-77:2000. It was derived by CENELEC from IEC 335-2-77:1996. It supersedes BS 345
5、6 Part 2: Section 2.32:1974 which will be withdrawn on 2003-01-01. The CENELEC common modifications have been implemented at the appropriate places in the text and are indicated by a sideline in the margin. The UK participation in its preparation was entrusted by Technical Committee CPL/61, Safety o
6、f household electrical appliances, to Subcommittee CPL/61/23, Lawnmowers, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informe
7、d; monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this subcommittee can be obtained on request to its secretary. From 1 January 1997, all IEC publications have the number 60000 added to the old number. For instance, IEC 2
8、7-1 has been renumbered as IEC 60027-1. For a period of time during the change over from one numbering system to the other publications may contain identifiers from both systems. Cross-references Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists norm
9、ative references to international publications with their corresponding European publications. The British Standards which implement these international or European publications may be found in the BSI Standards Catalogue under the section entitled International Standards Correspondence Index, or by
10、 using the Find facility of the BSI Standards Electronic Catalogue. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immuni
11、ty from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, the EN title page, pages 2 to 55 and a back cover.

45、ulated, by insulation equivalent to supplementary insulation, from other accessible metal parts which are within 75 mm of the ground measured as a clearance or from accessible metal parts connected to such parts. Cable restraints/guides are not considered to be operator controls. For rotary mowers,
46、the cutting means shall be insulated from other parts, which are accessible when the appliance is in its normal position of use, by insulating material equivalent to supplementary insulation. Compliance is checked by inspection, by measurement and for the covering of insulating material on handles,

After conditioning, the sample is allowed to attain approximately room temperature. Inspection shall show that the covering has not shrunk to suc
48、h an extent that the required length of 150 mm or the required insulation is no longer given or that the covering has not peeled off, so that it may move longitudinally. After this, the sample is maintained for 4 h at a temperature of (-10 ? 2)C. While still at this temperature, the sample is then s

The weight A having a mass of 300 g falls from a height of 350 mm onto the chisel B of hardened steel, the edge of which is placed on the sample. One impact is applied to each place where the covering is likely to be weak or damaged in intended use, the distance between the points of impact being at least 10 mm. After this test, inspection shall show that the covering has not peele
