5、s been prepared by Technical Committee CEN/TC 142 “Woodworking machines Safety” (Secretariat: UNI, 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-mas

6、chinen Sicherheit of Section Holzbearbeitungsmaschinen. Representatives of manufacturers and users of combined woodworking machines and of the employers liability insurance associations contributed to this standard. This standard contains specifications meeting the essential requirements set out in

7、Annex I of the new “Machinery Directive”, Directive 2006/42/EC, and which apply to combined woodworking 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 the directive. Once th

8、is standard is cited 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

9、2 and in the bibliography of this standard have been published as the corresponding DIN EN or DIN EN ISO Standards with the same number. The International Standards and publications referred to in this document have been published as the corresponding DIN ISO Standards with the same number, except f

Amendments This standard differs from DIN EN 940:2009-12 as follows: a) in Subclause 5.2.1.1 the requirements for saf

11、ety-related parts for control systems have been revised in accordance with EN ISO 13849-1:2008 and Performance Levels (PL) have been introduced; b) Subclauses 5.2.1.2 and 5.2.1.3 have been deleted entirely; c) in Subclauses 5.2.4 and 5.2.5 “safe torque off” (STO) for an emergency stop and alternativ

12、ely, “safe stop 1” (SS1) for a normal stop may be used for stopping the machine; d) in Subclause 5.4.3 additional requirements relating to the chip and dust extraction system have been included; e) in Subclause 6.3 additional requirements relating to the instruction handbook have been included; f) A
