24、hanges: rewording of some clauses; alignment to the European Machinery Directive 2006/42/EC; alignment to EN 60335-1:2012. This document is to be used in conjunction with EN 60335-1:2012 “Household and similar electrical appliances Safety Part 1: General requirements”. When “Part 1” is mentioned in

25、this standard, it refers to EN 60335-1:2012. This document supplements or modifies the corresponding clauses in Part 1, so as to convert that publication into the European Standard “Particular requirements for pedestrian-controlled walk-behind mains operated scarifiers and aerators”. Where a particu

26、lar subclause of Part 1 is not mentioned in this document, that subclause applies as far as is relevant. Where this standard states “addition”, “modification” or “replacement”, the relevant text in Part 1 is to be adapted accordingly. Compliance with the relevant clauses of Part 1 together with this

27、 document provides one means of conforming to the specified essential health and safety requirements of the Directive. This European Standard follows the overall requirements of EN ISO 12100. Warning: Other requirements arising from other EU Directives can be applicable to the products falling withi

28、n the scope of this European Standard. The following numbering system is used: subclauses , notes, tables and figures that are numbered starting from 101 are additional to those in Part 1; additional annexes are lettered AA, BB, etc.; Note In this European Standard the following print types are used

29、: - requirements proper: in roman type; - test specifications: in italic type; - explanatory matter: in smaller 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 bold. Common modifications are ind

30、icated by a vertical line in the left margin of the text. BS EN 50636-2-92:2014 5 EN 50636-2-92:2014 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 for identifying any or all such

31、patent rights. This document has been prepared under a mandate given to CENELEC by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For the relationship with EU Directive(s) see informative Annex ZZ, which is an integral part of

32、 this document. BS EN 50636-2-92:2014EN 50636-2-92:2014 6 Introduction This document is a type C standard as stated in EN ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations and events are covered is as indicated in the scope of this document. When provisions of

33、this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the other standards, for machines which have been built and designed to the provisions of this type C standard.

This European Standard specifies safety requirements and their verification for the design and construction of pedestrian controlled walk-behind mains operated scarifiers and aerators, hereinafter referred to as machine(s), which are de

35、signed for re-generating lawns by, for instance, combing out grass, thatch and moss or cutting vertically into the lawn face using tines which rotate about a horizontal axis. This standard applies in conjunction with Part 1. NOTE 1 Lawn scarifiers are also known as lawn rakes. This European Standard

36、 does not apply to non-powered scarifiers and aerators, battery powered scarifiers and aerators, vertical axis scarifiers and aerators or those aerators which cut into the soil by means of a reciprocating motion and ride-on machines. This European Standard does not apply to lawnmowers (EN 60335-2-77

37、); lawn trimmers (EN 60335-2-91); lawn edge trimmers (EN 60335-2-91); lawn edgers, flail mowers, sickle-bar mowers or agricultural mowers. This European Standard is not applicable to aerators/scarifiers which are manufactured before the date of publication of this document. This European Standard de

38、als with all the significant hazards presented by pedestrian-controlled lawn scarifiers and lawn aerators when they are used as intended and under conditions of misuse which are reasonably foreseeable.
