DIN EN 15892:2011-05 EN 15892:2011 (E) 4 1 Scope This European Standard specifies a type test method to measure noise levels inside the drivers cabs of railway vehicles for assessing compliance with the relevant European
20、 legislation. NOTE The relevant European legislation includes Directive 2003/10/EC of 6 February 2003 and the Commission Decisions of 23 December 2005 (Technical specification for interoperability relating to the subsystem rolling stock noise of the trans-European conventional rail system) and of 21
21、 February 2008 (Technical specification for interoperability relating to the rolling stock sub-system of the trans-European high-speed rail system). This method is applicable to: the measurement of noise inside drivers cab resulting from the sounding of external warning horns when the vehicle is sta
22、tionary; the measurement of noise inside the driver cab while the vehicle is running. The method is not applicable to: complementary measurements that can be requested for acceptance tests, but which are not required by the TSIs referred to in this standard; the measurement of the noise from interna
23、l and external audible devices other than external warning horns; routine monitoring of the noise exposure of train crew. The test procedures specified in this European Standard are of engineering grade (grade 2) with a precision of 2 dB, which is the preferred method for noise declaration purposes,

32、ilar devices 4 Measurement quantities All noise measurements shall be reported in terms of A-weighted equivalent continuous sound pressure level, LpAeq,T, over a definedmeasurement time interval, T in seconds. 5 Instrumentation and calibration 5.1 Instrumentation Each component of the instrumentatio
33、n system shall meet the requirements for a type 1 instrument specified in EN 61672-1:2003. A suitable microphone windscreen shall always be used for external measurements and is recommended for in-cab measurement. The compliance of the calibrator with the requirements of EN 60942 shall be verified a
34、t least once a year. The compliance of the instrumentation system with the requirements of EN 61672-1 and EN 61672-2 shall be verified at least every 2 years. The date of the last verification of the compliance with the relevant European Standards shall be recorded. 5.2 Calibration Before and after
35、each series of measurements a sound calibrator meeting the requirements of Class 1 according to EN 60942:2003 shall be applied to the microphone(s) for verifying the calibration of the entire measuring system at one or more frequencies over the frequency range of interest. If the difference between
36、the two calibrations is more than 0,5 dB, all the measurement results shall be rejected. 6 Tests when sounding the external warning horn 6.1 Test conditions 6.1.1 Environmental conditions The train shall be positioned in an open environment, and therefore not in a building or in a tunnel. Except for
37、 the ground, there shall not be any acoustically reflective (hard) surfaces comprising such materials as steel or concrete, including other trains and fixed structures, within 10 m of the external surfaces of the sides of the cab within which tests are being undertaken. Similarly, there shall not be
38、 any acoustically reflective surfaces within 25 m of the external surface of the front end of the cab. 6.1.2 Vehicle conditions The vehicle shall be stationary. DIN EN 15892:2011-05 EN 15892:2011 (E) 7 Air management systems, including grilles, filters and fans, shall be clear of any obstruction. Wi
39、ndscreen wipers shall not be in operation during the measurements. During the measurements, the doors and windows of the vehicle shall be kept closed. The minimum number of people necessary to carry out the acoustic tests shall be present in the cab during the measurements. The cab shall be in the c
40、ondition that will apply when in service. The horns shall be inspected for debris, which shall be removed if found to be present. NOTE The sound source that is to be measured, the external warning horn, is inherently of high sound level, and therefore typical internal background noise levels in the
41、cab when stationary are unlikely to interfere with the measured results. Nevertheless, it is advisable to run only those systems on the train that are essential to allow the external warning horn to sound, and to avoid positioning the vehicle at locations where other high noise level sources are pre
42、sent. 6.1.3 Track conditions No track condition. 6.2 Test procedure The stationary measurements require the noise level in the vicinity of the drivers ears to be quantified when the external warning horn is sounded. When the cab contains more than one set of complete driving controls, the test shall
43、 be carried out at each of these positions. This is not necessary at auxiliary driving positions where a full set of controls is not present. When the external warning horn has more than one operating control, the test shall be carried out using each of these controls. If the vehicle or multiple uni
44、t has two cabs and is symmetrical about its longitudinal centre, it is only necessary to carry out the full test within one cab provided the horn configuration and installation is identical for both cabs. If this is not the case, the tests shall be carried out in both cabs and the higher resultant l
45、evel shall be recorded. Sound pressure levels shall be measured at the normal operational energy level available on the vehicle. When the external warning horn has two or more tones or chords the following tests shall be carried out for both or all of these. When the acoustic warning has an option f
46、or a loud or quiet setting, the loud setting shall be used. Measurement conditions shall comply with EN 15153-2 for the measurement of horn performances. If the value of LpAeq,T measured under these conditions is outside the range specified for this test within EN 15153-2, or if these measured level
47、s before and after the stationary cab noise measurements differ by more than 3 dB, the cab noise results are invalid. The background noise level within the cab shall be measured and recorded at the beginning and end of the stationary measurement, in terms of LpAeq,Tover a measurement time interval,
48、T, of 20 s. This measurement shall be obtained at the same position on both occasions, and that position is to be chosen from one of the available eight locations as defined below. The measurement shall be carried out at eight evenly spaced microphone positions in a horizontal plane at the height of
49、 a seated drivers ears, at a radius of 25 cm, while the external warning horn is sounding. The position of the seated drivers ears, if not defined elsewhere, shall be taken at 0,80 m 0,05 m vertically above the centroid of the unloaded seat surface. If the seat height is adjustable, this adjustment shall be set at midrange. The height of this nominal position for the drivers seat above the floor shall be recorded. NOTE 1 In case a headrest pre
