In particular, this visualisation should be made for the catering service areas, the composite vehicles smoking/non-smoking, toilet/washrooms and the driving cab in order to verify that the air conditioning installation is well designed to avoid the propagation of odours. 5.2 Dynamic air movement tests If appropriate, measurements of air speed and/or pressure shall be done during dynamic tests. These measurements shall be applied to the following air flows: fresh, exhaust, condenser. These results shall be compared with measurements taken whilst using the same equipment on a stationary vehicle. 5.3 Comfort tests 5.3.1 Critical air speed The purpose of these measurements is to find, as a minimum, the three seated positions which are the most unfavourable in the comfort envelope (see Annex G). 5.3.2 Measurement of air speeds These measurements shall be carried out without the simulation of the thermal and volumetric effects of occupation (the heating elements, humidification equipment or dummies can affect the measurements inside the passenger space). It is recommended, for information purpose only, to carry out further measurement: with a volumetric occupation of a compartment or a bay simulated with dummies, to continuously record the passenger space air speeds in accordance with 10.2 with the thermal output of occupation being simulated throughout the regulation tests.

EN 13129-2:2004 (E) 8 6 Climatic tests 6.1 General remarks Annex A defines a minimum schedule of tests which enables the verification of comfort parameters defined in EN 13129-1. The order of the tests is not obligatory but shall be compatible with the physical characteristics of the climatic chamber 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 equipment such as, for example, doors, toilet equipment, power supply, lighting, special equipment, etc, need to be tested, these tests should not interfere in any way with the tests on the air conditioning systems. 6.2 Preheating test The test conditions for preheating are defined in Annex A. Before the start of the pre-heating test, the interior temperatures of the air and the interior surfaces shall be the same as the exterior temperature and stabilised at ± 1 K for at least 1 h. 6.3 Precooling test The test conditions for precooling are defined in Annex A. Before the start of the precooling tests, the interior temperatures of the air and the interior surfaces shall be the same as the exterior temperature and stabilised at ± 1 K for at least 1 h. At this time, before starting the precooling test, the artificial sunlight equipment shall be switched on for 2 h, corresponding to the values given in Annex E of EN 13129-1:2002 with doors and windows closed. 6.4 Regulation tests 6.4.1 Procedure Starting from stabilised operation (see 3.36 of EN 13129-1:2002), 1) one changes a parameter (interior or exterior) 2) after 90 minutes or three similar consecutive control cycles the results obtained shall be in accordance with the comfort conditions defined in EN 13129-1. 6.4.2 Tests in heating mode 6.4.2.1 The tests shall be carried out at the temperatures given in Table 1: Table 1 — Mean exterior temperatures (Tem) for tests in heating mode Zone I Zone II Zone III Temperature Temperature Temperature - 10 °C 0 °C + 10 °C - 20 °C - 10 °C 0 °C + 10 °C - 40 °C - 10 °C 0 °C + 10 °C SIST EN 13129-2:2004

The same check shall be made with 70 % to 80 % of the temperature setting devices at the maximum position and the remainder at minimum. 6.4.3.4 To check the effect of occupation, total or partial, on the regulation system, tests with a simulated occupation shall be carried out in accordance with 10.2. 6.4.3.5 The tests carried out in the presence of wind are intended to check the behaviour of the air conditioning installation and the tightness of the vehicle body, as well as the behaviour of the exhaust air outlets. 6.4.3.6 In order to verify the effect of the solar gain on the control system, the first test shall be carried out with a solar exposure of at least 4 h; the balance of tests will then follow the procedure of 6.4.1. 6.4.4 Tests with variable mean exterior temperature (Tem) The regulation tests carried out with a mean exterior temperature (Tem) that decreases or increases by 3 K/h are intended to check the behaviour of the air conditioning installation and its control system during the change over from the cooling mode to the heating mode and vice versa; with and without supplementary disturbance caused by occupation and solar radiation of the vehicle. SIST EN 13129-2:2004
EN 13129-2:2004 (E) 10 The tests are also intended to record the start conditions of the modes of heating and/or ventilation and/or cooling. To carry this out, the corresponding mean exterior temperature (Tem) shall be stabilised for 30 min. 7 Tests at extreme exterior operating conditions It will be necessary to check the operation of the air conditioning equipment at the extreme operating temperatures specified for the zones defined in 5.2 of EN 13129-1:2002. 8 Complementary tests 8.1 Verification of the anti-freeze protection 8.1.1 General remarks Not specific to the air condition comfort test, but is complementary to it, the verification of anti-freeze protection shall be carried out if there is a functional connection between the air conditioning system and the water installation. 8.1.2 Aim of the tests The object of the tests is to verify that the on board equipment does not suffer from damage caused by freezing in accordance with 1.4 of the document UIC 563:1990. 8.1.3 Test procedure The water tanks are filled at least five hours before the start of the tests with water at a temperature below 15 ºC: for each type of tank, one tank is 1/4 full, the other tanks are filled to 3/4 full. The control functions of the installation are performed in according to the test operation instruction. Before the start of the tests in line with the document UIC 563, there is a need to stabilise for 5 h, the mean exterior and interior temperatures of the areas reserved for passengers. Minimum duration of cooling of the vehicle: see UIC 563. The control functions of the installation are performed in accordance with the operation instruction. The temperature of the tanks, exhaust valves, pipes and other items exposed to a risk of freezing shall be recorded. The test shall be discontinued if there is a risk of icing-up. 8.2 Determination of the coefficient k 8.2.1 Purpose of the test The coefficient k characterises the thermal quality of a vehicle (efficiency of the insulation and influence of air infiltration). 8.2.2 Definition The global coefficient k is defined by the following formula: ()emimeTTAPk−×= The surface Ae is the developed exterior surface of the assembly including walls, ceiling, floor and ends of the structure for all or part of the vehicle under consideration. This shall include windows, doors and openings. SIST EN 13129-2:2004
EN 13129-2:2004 (E) 11 P is the thermal power released inside the vehicle, necessary to maintain constantly the difference in absolute value between the mean interior temperature (Tim) measured at 1,1 m, of all or part of the vehicle according to Annex C, and the mean exterior temperature (Tem). 8.2.3 Procedure The openings for fresh air and exhaust air are sealed, but not insulated. The air conditioning installation is isolated. The vehicle is without power (except for the batteries), the doors and the windows are closed. Unsealed gangways are normally only blocked by the vehicle door. Gangways without a vehicle door or sealed gangways shall be blocked by a temporary panel whose thermal transmission coefficient is less than 0,5 W/m²K. It is necessary to provide a heating installation independent of that of the vehicle, controllable to a low output in the vehicle interior (and) distributed in the comfort envelope and/or annex areas. The uniformity of the temperatures inside the vehicle shall be guaranteed by fans. The power consumption of the system and the fans shall be recorded separately. All the measured data shall be recorded at minimum every 1 min. The value of the temperature difference |Tim−Tem| shall be (25 ± 5) K. It is recommended that this test is carried out with Tem = + 5 °C ± 2 K. The output of the heating system and of the ventilation is maintained constant, the determination of the coefficient k is possible after stabilisation of the temperatures: The values of Tem and |Tim−Tem| shall be determined and averaged over a period of 30 min. The variation of these values, over a minimum period of 3 h shall be less than 0,1 K. The range of temperatures relating to different points of measurement (interior and exterior) shall be less than 2 K. The coefficient k is calculated using the measurements take
