This document specifies the characteristics for suspension diaphragms to achieve, together with applicable inspection and test methods to be carried out for verification. An air spring system usually consists of a diaphragm (subject of this document) and additional components such as either emergency or additional springs, or both, and other assembly parts. This document does not detail the other components of air suspension or control systems such as air reservoirs, air piping, levelling system, frames, stiffeners, emergency suspension systems or elastic supports (such as series springs), etc., which will affect the diaphragm performance. This document applies to suspension diaphragms (inflated with air) 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. These parts are typically made with elastomer, textile fabrics and metallic beads.

This document is applicable to the calculation, measurement and/or verification of energy consumption of railway vehicle HVAC (heating, ventilation and air-conditioning) systems. The HVAC system energy consumption is simulated, calculated, measured and validated in accordance with the requirements of thermal comfort defined in ISO 19659-2, considering the same category of passenger railway vehicles as detailed in ISO 19659-2, Clause 4: — Category 1 (e.g. main line, intercity, long distance, high speed); — Category 2 (e.g. suburban, commuter, regional); — Category 3 (e.g. urban, LRV, tram, metro/subway). This document only covers the passenger area HVAC systems. Driver’s cab HVAC systems are excluded but could be treated in a similar way.

This document defines the classification, technical requirements, and markings for the following bodyside windows: standard windows: standard fixed windows; standard movable windows; emergency windows: emergency escape windows; emergency access windows. NOTE In certain situations, emergency escape windows and emergency access windows are the same window. This document applies to bodyside windows constructed from glazing materials only. This document sets out requirements that apply to the glazing with its associated mounting arrangement. This document applies to all windows mounted to the side of all types of railway vehicles, including heavy and urban rail vehicles. This includes windows mounted on the side of saloons, restaurant/buffet cars, vestibules, toilets, driving cabs, crew compartments and technical rooms.

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.

This document specifies a general approach for achieving thermal comfort for passenger compartments or saloons of railway vehicles (single level or double-decker) such as main line, regional/suburban and urban vehicles used in public transportation services. This document also describes guidelines to specify conditions, performance values and the comfort parameter measurement methods for compartments, saloons and local annexes. This document does not apply to the thermal comfort of the cab driver.

This document specifies a calculation method of recyclability and recoverability rates for rolling stock. The method defined in this document applies to the design of new rolling stock. However, it can be applied to other existing rolling stock depending on available information. If calculation of recyclability or recoverability is applied to separate parts and/or products used in rolling stock and a specific calculation standard or method exists for the part and/or product, such standard or method can be applied, if relevant. This calculation method is applicable regardless of any geographical concern. This calculation method is applicable to any stage of life cycle of rolling stock. The calculated recyclability and recoverability rates are valid at the point of delivering the rolling stock products or equipment. Future recycling technologies or predicted trends with respect to the recycling industry are excluded from any consideration for this calculation method. This calculation method considers the four main treatment processes, which are reuse, recycling, energy recovery and disposal (Figure 1). Process losses of recycling are treated in the disposal stage. The residue substances of the energy recovery stage (mostly ash and slag) and the residue of the incineration process of the disposal stage are most likely landfilled.
