1 Scope This European Standard is applicable to railway vehicle driving cabs which are air-conditioned or heated/ventilated. These include: locomotives; mainline, suburban or regional vehicles; urban vehicles such as metros and trams. This European Standard does not consider the special operational requirements of shunt locomotives. This European Standard specifies the comfort parameter measurement methods for driving cabs. The comfort parameters and their tolerances cited in this European Standard are defined in EN 14813-1. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 14813-1:2006, Railway applications — Air conditioning for driving cabs — Part 1: Comfort parameters EN ISO 3381, Railway applications — Acoustics — Measurement of noise inside railbound vehicles (ISO 3381:2005) EN ISO 7726:2001, Ergonomics of the thermal environment — Instruments for measuring physical quantities (ISO 7726:1998) CIE 85, Solar spectral irradiance2) 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 14813-1:2006 apply. 4 Test classification Two levels of testing are detailed in this European Standard. TL1 is a simplified level that gives principle information about the functionality of the system. It does not aim to verify the comfort parameters and performance of the system. It can be done in a workshop or at a yard. TL2 is a full level test to verify the comfort parameters and the performance of the system. This test shall be performed in a climatic chamber or in an appropriate environment. The operator shall detail in his contractual specification the test classification.

EN 14813-2:2006 (E) 7 In the absence of any detail, the full level of testing (TL2) shall apply. If not stated otherwise, the following test requirements apply to both TL1 and TL2. 5 Preliminary verifications It is advised that preliminary tests are carried out to verify the electrical and electronic assemblies, the functional logic of the control system, the air tightness of the air distribution system, the water tightness of the car, the thermal capacity of the air conditioning equipment and so on. These verifications should be conducted before proceeding to the comfort test. 6 Comfort tests 6.1 Air movement tests3) 6.1.1 General remarks The tests shall be carried out under the following conditions: vehicle stationary and protected from rain; altitude < 1 000 m above sea level; exterior air speed between 0 km/h and 5 km/h; exterior temperature between + 15 °C and + 30 °C. In the case of different altitude and exterior temperature, correction shall be made. 6.1.2 Air flow rates The flow rates of outside air (fresh air) shall be measured in accordance with 10.5. 6.1.3 Pressure differentials (visualisation) If appropriate, this can be shown up by the movement of smoke between the two relative areas. The visualisation shall be made for driving cabs to verify that the air conditioning installation is well designed by preventing the transfer of smoke to a non-smoking area. 6.2 Measurement of air speeds These tests shall be carried out during the climatic tests without the simulation of the thermal and volumetric effects of occupation (the necessary heating elements, humidification and ventilation equipment can affect the measurement inside the comfort envelope). Measuring points shall be according to Annex D. 6.3 Thermal comfort It is recommended for a detail analysis of thermal comfort to use thermal mannequins.

EN 14813-2:2006 (E) 8 7 Climatic tests 7.1 General remarks Annex A defines the test programme for level TL1. Theses tests are only carried out on a stationary vehicle at air speed as defined in Annex A. Annex B defines a minimum schedule of tests for level TL2 which enables the verification of comfort parameters defined in EN 14813-1. The order of the tests is not obligatory but shall be compatible with the physical conditions of the test and the means of measurement. Throughout the tests, all the values at the measuring points defined in Clause 11 shall be recorded continuously, as well as the energy consumption and the power absorbed by the air conditioning installation itself, and the whole of the vehicle. Should other requirement such as for example the doors, the power supply, the lighting etc., need to be tested, these tests shall not interfere in any way with the tests on the air conditioning equipment installed. 7.2 Preheating test 7.2.1 Test level TL1 The test conditions for preheating are defined in Annex A. Before the start of the preheating test, the interior temperatures of the air and the interior surfaces shall be within ± 2 K of the exterior air temperature for at least 15 min. It is anticipated that the temperature stabilisation process may take up to 8 h. 7.2.2 Test level TL2 The test conditions for preheating are defined in Annex B. Before the start of the preheating test, the interior temperatures of the air and the interior surfaces shall be within ± 1 K of the exterior air temperature for at least 15 min. 7.3 Precooling test 7.3.1 Test level TL1 The test conditions for precooling are defined in Annex A. Before the start of the precooling test, the interior temperatures of the air and the interior surfaces shall be within ± 2 K of the exterior air temperature for at least 15 min. At this time, before starting the precooling test, the artificial sunlight equipment or equivalent heating power shall be switched on for 2 h, corresponding to the values given in Annex D of EN 14813-1:2006, with doors and windows closed. 7.3.2 Test level TL2 The test conditions for precooling are defined in Annex B. Before the start of the precooling test, the interior temperatures of the air and the interior surfaces shall be within ± 1 K of the exterior air temperature for at least 15 min. SIST EN 14813-2:2007
EN 14813-2:2006 (E) 9 At this time, before starting the precooling test, the artificial sunlight equipment or equivalent heating power shall be switched on for 2 h, corresponding to the values given in Annex D of EN 14813-1:2006, with all doors and windows closed. 7.4 Regulation test The test conditions are defined in Annex A and Annex B. Starting from stabilised operation (see EN 14813-1:2006, 3.34), after a changing of a parameter (interior or exterior), wait 60 min or three similar consecutive control cycles, then the results obtained shall be in accordance with the requirements defined in EN 14813-1. 8 Tests at extreme exterior operating conditions The operation of the air conditioning equipment, when installed on the vehicle, shall be checked at the extreme operating temperatures defined in EN 14813-1:2006, 6.3. For TL1, these tests may be carried out on the air conditioning equipment only. 9 Complementary tests 9.1 Determination of the coefficient k 9.1.1 Purpose of the test The coefficient k characterises the thermal quality of a driving cab (efficiency of the insulation). The test shall be carried out only at TL2. The test conditions are defined in Annex B. 9.1.2 Definition The global coefficient k is defined by the following equation: ()TemTime−×=APk where the
