28、ledge of the mechanical system of which it formspart. Specific characteristics are therefore needed for each case, which only the customer can specify.This European Standard is the result of the studies and research to improve the performances and quality ofelastomer-based mechanical parts in order
29、to meet the requirements of railway rolling stock.This European Standard is designed for the railway operators, the manufacturers and equipment suppliers of therailway industry as well as for the suppliers of elastomer-based mechanical parts.BS EN 13913:2003 EN 13913:2003 (E)71 ScopeThis European St

31、quality monitoring of elastomer-based mechanical parts in manufacture.This European Standard applies to elastomer-based mechanical parts designed to be fitted on railway vehicles andsimilar vehicles running on dedicated tracks with permanent guide systems, whatever the type of rail and therunning su
32、rface.Typical applications of elastomer-based mechanical parts include: vehicle suspension systems; equipment mounting systems; joints (e.g.: end-mountings of dampers, elastomer-based bearings, elastomer-based parts used on mechanicalcouplings); limit stops.These parts can be: made entirely of elast
33、omer, operating on their own or in combination with other elastic parts; made up of elastomer and other materials, adherent together or not.This European Standard does not apply to: rubber diaphragms for pneumatic suspension springs; elastic parts of buffing and drawgear springs; diaphragms, bellows
