This document (EN 1870-3:2014) 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 DIN-Normenausschuss Maschinenbau (DIN Standards Committee Mechanical Engineering), Working Committee NA 060-06-01 AA Holzbearbeitungs-maschinen Sicherheit of Section Holzbearbeitungsmaschinen. Representatives of manufacturers and use

7、rs of down cutting cross-cut saws and dual purpose down cutting cross-cut saws/circular saw benches, 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 Direc

8、tive”, 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 require-ments of that directive. Once this standard is cited in the Official Journal of the Eu

9、ropean 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 Bibliography of the EN have been publishe

10、d as the corresponding DIN EN or DIN EN ISO Standards with the same number. For the International Standards referred to there are no national standards available. Amendments This standard differs from DIN EN 1870-3:2009-08 as follows: a) Clause 2 “Normative references” has been updated; b) in Subcla

11、use 5.2 “Controls”, the design requirements for control circuits in certain categories have been replaced by specifications for performance levels; c) Subclause 5.2.1.2 “Use of protective devices” has been added; d) in Subclause 5.3.2 “Risk of break-up during operation”, the requirement has been add

12、ed to perform for plastic material (except for polycarbonate) used for guards an impact test; e) in Subclause 5.3.4 “Braking”, requirements for the braking system have been modified and the braking test has been moved to Annex D; f) Subclause 5.4.3 “Emission of chips and dust” has been revised to in

13、clude further requirements; g) Annex E “Impact test method for guards” has been added; h) Annex ZA (informative) “Relationship between this European Standard and the Essential Requirements of EU Directive 98/37/EC” has been deleted; DIN EN 1870-3:2015-02 3 i) the former Annex ZB is now Annex ZA (inf

Th

43、is European Standard is a type “C” standard as defined in EN ISO 12100:2010. The extent to which hazards are covered is indicated in the scope of this document. 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 s

44、tandard 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 requirements of this document are directed to manufacturers and their authorized representatives of down cutting cross-cut saws and

45、dual purpose down cutting cross -cut saws/circular saw benches. They are also useful for designers. This document also includes information to be provided by the manufacturer to the user. Common requirements for tooling are given in EN 847-1:2013. Electrically driven machines excluded by the scope o

46、f this document are covered by the requirements of EN 61029-1:2000, EN 61029-2-9:2009 and EN 61029-2-11:2009.
