Representatives of manufacturers and users of pendulum cross-cut sawing machines, and of the employers liability insurance associations contributed to this standard. This standard contains specifications meeting the essential requirements set ou

7、t in Annex I of the “Machinery Directive”, 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 cite

8、d in the Official Journal of the European 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 European Standards referred to in Clause 2 and in the Biblio

9、graphy of the EN have been published as the corresponding DIN EN or DIN EN ISO Standards with the same number.

11、”, the definitions of pendulum cross-cut sawing machines have been modified and the definition of automatic pendulum cross-cut sawing machines has been deleted; d) in Clause 5 “Safety requirements and/or measures”, requirements for the functional safety of the control system of the machine, for the

12、braking system and for the protection against mechanical hazards have been revised; e) in Subclause 6.4 “Instruction handbook”, further requirements have been included; f) Annex A (normative) “Impact test method for guards” has been added; g) Annex B (normative) “Braking tests” has been added.

42、quirements 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 are covered are indicated in the scope of this document. When provision

43、s 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. The require

46、id wood, chipboard, fibreboard, plywood and also these materials when covered with plastic edging and/or plastic/light alloy laminates when they are used as intended and under the conditions foreseen by the manufacturer including reasonably foreseeable misuse. This European Standard does not apply t

47、o: a) machines for cross cutting logs; b) machines where the saw unit can be rotated about a horizontal axis. NOTE The requirements of this European Standard apply to all machines whatever their method of control e.g. electromechanical and/or electronic. This European Standard is primarily directed

48、at machines which are manufactured after the date of its publication as EN. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
