ISO/TC 269/SC 2 - Rolling stock

This document applies to elastomer-mechanical parts, as defined in ISO 22749-1. This document specifies: — approval procedure to be implemented by the customer; — guidelines for qualification of the product with specified requirements; — quality monitoring of rubber and rubber to metal parts in manufacture. 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 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 does not apply to on-track machines.

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.

This document specifies the methodologies for calculation of braking performance for railway rolling stock. This document describes the general algorithms/formulae using instantaneous value inputs to perform calculations of brake equipment and braking performance, in terms of stopping/slowing distances, braking power and energy for all types of rolling stock, either as vehicles or units. The calculations can be performed at any stage of the assessment process (design, manufacture, testing, verification, investigation, etc.) of railway rolling stock. This document does not set out specific acceptance criteria (pass/fail). This document is not intended to be used as a design guide for the selection of brake systems and does not specify performance requirements. This document does not provide a method to calculate the extension of stopping distances when the level of demanded adhesion exceeds the available adhesion (wheel slide activity). This document contains examples of the calculation of brake forces for different brake equipment types and examples of the calculation of stopping distance for vehicles or units.

This document provides additional information to assist the understanding and the use of ISO 20138-1. The calculations in this document follow the same principles but they are slightly different. This document contains country specific calculation approaches currently in use and represents the state of knowledge including for calculating: — stopping and slowing distances; — equivalent response time; — brake performance; — brake ratio.

This document specifies methodologies for calculation of braking performance for railway rolling stock and is applicable to all countries. This document describes the general algorithms/formulae using mean value inputs to perform calculations of brake equipment and braking performance in terms of stopping/slowing distances, stationary braking, power and energy for all types of rolling stock, either as single vehicles or train formations, with respect to the braking distance. The calculations can be used at any stage of the assessment process (design, manufacture, testing, verification, investigation, etc.) of railway rolling stock. This document does not set out the specific acceptance criteria (pass/fail). This document is not intended to be used as a design guide for selection of brake systems and does not specify performance requirements. This document does not provide a method to calculate the extension of stopping distances when the level of available adhesion is exceeded (wheel slide activity). This document contains examples of the calculation of brake forces for different brake equipment types and calculation of stopping distance and stationary braking relevant to a single vehicle or a train.

ISO 19659-1:2017 is applicable to rail vehicles and specifies the terms, definitions, symbols and abbreviated terms to be used in the ISO 19659 series, heating, ventilation and air conditioning for rolling stock.
