This European Standard shall be given the stat

24、us of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2014, and conflicting national standards shall be withdrawn at the latest by June 2014. Attention is drawn to the possibility that some of the elements of this document may be the subject o

25、f patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 13802:2004. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. The main changes w

26、ith respect to the previous edition are listed below. Clause 1 The complete hydraulic dampers, with their end mountings, are now considered in the scope. This new consideration has been taken into account in the whole standard. Clause 2 The normative references have been updated. 4.2.1.2 A new item

27、concerning the life cycle of the dampers has been added. 4.2.2.2 The value of minao,T to take by default has been decreased. 4.2.2.3 The value of minae,T to take by default has been decreased. 4.2.4 and 5.2.4 The requirements concerning the behaviour against the vibrational exposures are now given a

28、s recommendations. 4.3.3 A criterion about of the surface protection has been defined. 4.3.4 A criterion about the noise generated by the damper has been defined. 4.3.9 The supply of the value of the mass is now required. 4.4.1 A criterion about the orientation of the damper has been defined. 4.4.6

29、and 5.4.6 The definition of the dynamic characteristics of the dampers has been revised. 6.3 Requirements about the serial tests have been added. Clause 7 The position of the permanent marking of horizontally orientated dampers has been specified. B.2 Methods of calculation of the damper length have

30、 been defined in this new sub-clause.

The dampers covered in this standard include: dampers that control the dynamic behaviour of a ve

35、hicle: suspensions dampers, (e.g. primary vertical dampers, secondary vertical dampers and secondary lateral dampers); yaw dampers; roll dampers; inter-vehicles dampers. dampers that control the dynamic behaviour of mechanical systems: pantograph dampers; motor dampers, etc. All relevant terminology

36、 which is specific to the subject is defined in this European Standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated refere
