EN 13913:2003 (E)6IntroductionDesigning an elastomer-based mechanical part requires knowledge 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 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.SIST EN 13913:2004



EN 13913:2003 (E)71 ScopeThis European Standard defines:¾ characteristics that elastomer-based mechanical parts shall achieve, together with applicable inspection andtest methods to be carried out for verification;¾ approval procedure to be implemented by the customer;¾ guidelines for qualification of the product with specified requirements;¾ 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 surface.Typical applications of elastomer-based mechanical parts include:¾ vehicle suspension systems;¾ equipment mounting systems;¾ joints (e.g.: end-mountings of dampers, elastomer-based bearings, elastomer-based parts used on mechanicalcouplings);¾ limit stops.These parts can be:¾ made entirely of elastomer, operating on their own or in combination with other elastic parts;¾ made up of elastomer and other materials, adherent together or not.This European Standard does not apply to:¾ rubber diaphragms for pneumatic suspension springs;¾ elastic parts of buffing and drawgear springs;¾ diaphragms, bellows and seals;¾ hoses and tubings;¾ transmission belts.SIST EN 13913:2004
