This document applies to elastomer-mechanical parts designed to be fitted on railway vehicles and similar vehicles running on dedicated tracks with permanent guide systems, whatever the type of rail and the running surface. Typical applications of the elastomer-mechanical parts include: —    vehicle suspension systems; —    equipment mounting systems; —    joints (e.g. end-mountings of dampers, rubber-based bearings, elastomer-mechanical parts used on mechanical couplings); —    limit stops. These parts can be: —    made entirely of elastomer, operating on their own or in combination with other elastic parts; —    made up of elastomer and other materials, adherent together or not. This document specifies characteristics that rubber and rubber to metal parts are to achieve, together with applicable inspection and test methods to be carried out for verification. This document does not apply to: —    rubber diaphragms for pneumatic suspension springs; —    elastic parts of buffing and drawgear springs; —    diaphragms, bellows and seals; —    hoses and tubings; —    transmission belts.
