This document is a type C standard as defined in EN ISO 1210

42、0:2010. The machinery concerned and the extent to which hazards, hazardous situations and events are covered is indicated in the scope of this document. The requirements of this document are directed to manufacturers and their authorised representatives of double blade circular sawing machines for c

43、ross-cutting with integrated feed and with manual loading and/or unloading. This document is also useful for designers and importers. When provisions of 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 ove

44、r the provisions of other standards, for machines that have been designed and built according to the provisions of this type C standard. This document also includes information to be provided by the manufacturer to the user. Common requirements for tooling are given in EN 847-1:2005+A1:2007. DIN EN

46、/or unloading, hereinafter referred to as machines. These are machines designed to cut solid wood, chipboard, fibreboard and plywood, and also these materials when covered with plastic edging and/or plastic/light alloy laminate, when they are used as intended and under the conditions foreseen by the

47、 manufacturer including reasonably foreseeable misuse. This document does not apply to: machines for cross cutting logs; double blade up-cutting cross-cut sawing machines. This document is not applicable to machines which are manufactured before its date of publication as an EN. 2 Normative referenc
