This part of ISO 11452 specifies tests for electromagnetic immunity of electronic components for passenger cars and commercial vehicles, regardless of the propulsion system (e.g. spark-ignition engine, diesel engine, electric motor), to magnetic fields. These sources are classified into “internal magnetic field” (sources internal to the vehicle, e.g. vehicle electro-mechanical motors, actuators, ...) and “external magnetic field” (sources external to the vehicle e.g. power transmission lines, generating stations,…). To perform this test, the device under test (DUT) is exposed to a magnetic disturbance field. The radiating loop method can be applied to small DUTs or to larger DUTs by positioning the coil in multiple locations. The Helmholtz coil is sometimes used as an alternative method. This technique is limited by the relationship between the size of the DUT and the size of the coils. The electromagnetic disturbances considered in this part of ISO 11452 are limited to continuous narrowband electromagnetic fields.

The standard addresses the measurement of source terms for environmental noise calculation for rail traffic (including light rail). It is applicable to the measurement of in-service trains on operational tracks.It is not applicable to type acceptance testing of rolling-stock or tracks.The following rail traffic noise sources are in the scope:- Rolling noise ;- Traction noise ;- Aerodynamic noise ;- Impact noise (e.g. rail joints, switch & crossings, wheel flats) ;- Bridge noise ;- Squeal noise.Noise from rail vehicles at standstill is included e.g.: engine idling and auxiliary equipment.Noise from fixed installations (e.g.: stations, depots, electricity sub-stations) are not in the scope of this standard. Each source shall individually be characterized in terms of its frequency spectrum (up to one-third octave band details), source height and directivity. Rolling noise will then be described in terms of its generating wheel and rail roughness along with the vehicle and track transfer functions. Source terms will be specific to a vehicle and track type. The scope includes measurement procedures and conditions and sampling requirements.

The purpose of this document is to provide methods for quantifying the ride comfort of a passenger in a rail vehicle in response to the track sections it is operated over.The methods aim to quantify the effects of vehicle body motions on ride comfort and to make the assessment of passenger comfort predictable, repeatable, objective and meaningful.The methods and comfort scales are validated for people of good health.This document applies to passengers in rail vehicles operating on heavy rail networks.This document may also be used as a guide for example on urban rail systems, but their operational routes/environments may make it difficult to comply with the requirements of the test methods.This document applies to measurements of motions. It also applies to simulated motions. Guidance is provided on:- which method described within the document should be used for different scenarios;- typical values for different comfort levels;- the application of simulation.This document excludes health and safety issues, non-passenger carrying vehicles, vehicle homologation and safety, limit values, motion sickness, discomfort caused by accelerating and braking, design guidelines and measurement technology.

This European Standard specifies functional requirements (see clause 3) and specific safety requirements for four types of horses and bucks (see Table 1) in addition to the general safety requirements in EN 913.
