This European Standard shall be given the

18、 status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2011, and conflicting national standards shall be withdrawn at the latest by September 2011.

This document has been prepared under a mandate given to CEN/CENELEC/ETSI by the European Commission and the European Free Trade

20、Association, and supports essential requirements of EU Directive 2008/57/EC. For relationship with EU Directive 2008/57/EC, see informative Annex ZA, which is an integral part of this document. The “Recast” Directive 2008/57/EC of the European Parliament and of the Council on the interoperability of

21、 the rail system within the Community was published on 17th June 2008. The two previous EU directives 96/48/EC and 2001/16/EC on the interoperability of the High Speed and Conventional rail systems within the Community will therefore be repealed with effect from 19th July 2010. At this date the harm

25、 inside all kinds of vehicles on rails or other types of fixed track, hereinafter conventionally called “train”, except for track maintenance vehicles in operation. This standard is applicable for: type testing; periodic monitoring testing. The results may be used, for example: to characterise the n

26、oise inside these vehicles; to compare the internal noise of various vehicles on a particular track section. The test procedures specified in this European Standard are of engineering grade (grade 2, with a precision of 2 dB), that is the preferred one for noise declaration purposes, as defined in E

27、N ISO 12001. The standard describes tests during different operating conditions, i.e. driving, accelerating, decelerating and standstill. The chosen operating conditions are decided by the relevant authority or the train owner/operator. It is not mandatory to perform tests at all conditions. Infraso

28、und and messages intelligibility are not treated in this standard. The procedures specified for accelerating and decelerating tests are of survey grade. 2 Normative references The following referenced documents are indispensable for the application of this document.

43、rement quantities 4.1 General The quantities to be measured at all microphone positions for both type and monitoring tests are specified below. 4.2 Frequency analysis is required for type tests while it is optional for monitoring tests. The typical 1/3 octave band frequency range is from 31,5 Hz to

44、8 kHz according to EN ISO 266. It is important, however, that the lower frequency limit is chosen to ensure that the product of the lowest bandwidth and signal duration exceeds unity. 4.3 In presence of noise with suspected impulsive character, both LpAIeq,T and LpAeq,Tshall be measured. If they dif

45、fer by more than 3 dB the impulsive character is conventionally confirmed. 4.4 In presence of noise with suspected tonal character, at each microphone position it is suggested to make frequency analysis measurements according to 4.2. 4.5 The measurement quantity for trains running at constant speed

46、is the A-weighted equivalent continuous sound pressure level, LpAeq,T. Additionally, the A-weighted short-term equivalent continuous sound pressure level, LpAeq,1smay be measured. 4.6 For measurements on stationary vehicles, in presence of noise with suspected impulsive character, at each microphone

47、 position it is suggested to make two measurements: one with time weighting slow S, the other with time weighting impulse I (see EN 61672-1). 4.7 The measuring quantities for accelerating or braking tests shall be the maximum AF-weighted sound pressure level, LpAFmax, and the A-weighted equivalent c

48、ontinuous sound pressure level, LpAeq,T.
