Warranty of the part is also the responsibility of the man
44、ufacturer in accordance with the agreement with the purchaser. 4.2 Operating conditions The end cock shall be able to function under the following conditions: a) Where the air quality of the compressed air specified in ISO 8573-1:2001, class 4-4-5. This requirement is verified when tests are carried
45、 out in accordance with 5.2. b) In the temperature range for the environmental conditions to which the rail vehicle is submitted during its operation and at least for a temperature range defined by the class T2 of EN 50125-1. The purchaser can specify a higher temperature value if operational constr
46、aints demand it. This requirement is tested in accordance with 5.3.3, 5.3.7 and 5.3.12. c) The end cock shall withstand the external corrosion due to normal atmospheric pollutants as specified in EN 50125-1. The end cock is tested in accordance with the test shown in 5.3.13. d) In the vibrational en
47、vironment of the rail vehicle on which it is mounted and it shall remain in either the open or closed position. The cock shall be tested in accordance with 5.3.10. 4.3 Functional characteristics 4.3.1 General The operating handle of the end cock shall be equipped with a detent or latch system. The r
48、equirements given in 4.3.2 to 4.3.10 are defined to ensure the air flow through the brake pipe and main reservoir pipe and ensure no malfunction of the cock after the brake pipe test (as part of the brake test before the trains start).

49、losed positions The handle position shall be the same on any vehicle, so the opening and closing of the cock shall be achieved by turning its spindle through a minimum of 90 and not more than 100. Stops shall be provided at the extremes of rotation, so that the open and closed positions are achieved positively.
