5、Document comprises 94 pages 02.14 DIN EN 1870-19:2014-03 2 A comma is used as the decimal marker. National foreword This standard includes safety requirements. This document (EN 1870-19:2013) has been prepared by Technical Committee CEN/TC 142 “Woodworking machines Safety” (Secretariat: UNI, Italy).

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

7、lar saw benches (with and without sliding table), 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”, Directive 2006/42/EC, and which apply to mac

8、hines 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 Union, it is deemed a “harmonized” standard a

9、nd 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 this document have been published as DIN EN or DIN EN ISO Standards with the same number. There is no DIN Standar

10、d available which corresponds to the International Standard referred to. Amendments This standard differs from DIN EN 1870-1:2009-08 as follows: a) normative references have been updated; b) in Subclause 5.2 “Controls”, the design requirements for control circuits in certain categories have been rep

11、laced by specifications for performance levels; c) in Subclause 5.3.1 “Stability”, a stability test for displaceable machines has been included; d) in Subclause 5.3.4 “Braking”, requirements for the braking function have been rendered more precise; e) in Subclause 5.3.7 “Prevention of access to movi

12、ng parts”, saw blade guards mounted on wall, ceiling or floor have been excluded and requirements to prevent crushing and shearing hazards have been rendered more precise; f) in Subclause 5.3.9 “Safety appliances”, usable safety appliances have been extended; g) in Subclause 5.4.3 “Emission of chips

13、 and dust”, further requirements have been included for the chip and dust extraction system; h) requirements for the use of electronic components (EN 1870-1:2009, Annex J) have been deleted.
