This document (EN 1807-11:2013) has been prepared by Technical Committee CEN/TC 142 “Woodworking machines Safety” (Secretariat: UN

6、I, Italy). The responsible German body involved in its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Working Committee NA 060-06-01 AA Holzbearbeitungs-maschinen Sicherheit of Section Holzbearbeitungsmaschinen. Representatives of manufacturers and use

7、rs of semi automatic horizontal cross-cut sawing machines with one saw unit (radial arm saws), and of the employers liability insurance associations contributed to this standard. This standard contains specifications meeting the essential requirements set out in Annex I of the “Machinery Directive”,

8、 Directive 2006/42/EC, and which apply to machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of that directive. Once this standard is cited in the Official Journal of the European

9、Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The Standards referred to in this document have been published as the corresponding DIN ISO or DIN EN ISO

10、Standards with the same number, except for those below, which correspond as follows.

46、l safety requirements of the Machinery Directive, and associated EFTA regulations. This document is a type “C“ standard as defined in EN ISO 12100:2010. The machinery concerned and the extent to which hazards, hazardous situations and events covered are indicated in the scope of this document. When

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

48、e requirements of this document are directed to manufacturers and their authorised representatives of semi-automatic horizontal cutting cross-cut sawing machines with one saw unit (radial arm saws). It is also useful for designers. This document also includes examples of information which can be provided by the manufacturer to the user. Common requirements for tooling are given in EN 847-1:2013.
