70 °C without any deviation from the technical requirements specified in this European Standard;  at – 40 °C ≤ environmental temperature < – 25 °C without deviation from the main technical requirements specified in this European Standard but without affecting the function of the empty-loaded changeover device. Deviations from the technical requirement when testing at extremes are defined in 6.2.11. SIST EN 15624:2009

4.5 Compressed air quality It shall be possible to operate the empty-loaded changeover device without restrictions with at least the compressed air quality according to the following classes defined by ISO 8573-1:2001:  class 4 – for the maximum particle size and the maximum concentration of solid contaminants;  class 4 – for the water dew point;  class 4 – for the maximum total (droplets, aerosols and vapours) oil concentration. The empty-loaded changeover device shall be capable of operating in an air supply system that is not fitted with an air dryer, or when the air dryer is out of order. The air system should therefore include some means of preventing water collecting within the empty-loaded changeover device and hence freezing of the water in conditions below 0 °C. 4.6 Service life No specific requirements for the empty-loaded changeover device to attain a particular service life are contained in this European Standard.

6.2.4 Check of physical and geometrical characteristics 6.2.4.1 Procedure In accordance with the particular order documentation and approval drawings, dimensional accuracy shall be verified by means of appropriate measuring instruments and form gauges e.g. threaded connections may be checked using GO/NOT GO gauges in accordance with EN ISO 228-2. The external surfaces shall be checked for sharp edges and corners. 6.2.4.2 Pass/fail criteria The result is satisfactory if all the specified characteristics are met and no sharp edges and corners are present on the external surfaces. 6.2.5 Leakage 6.2.5.1 Positive load signal pressure devices 6.2.5.1.1 Procedure Mount the empty-loaded changeover device to the test bench positioned to receive the supply pressure and output a load signal pressure to the reservoir volume. The device operating mechanism shall be at its extended position. With vent cocks and load signal pressure isolating cock closed, open the supply pressure isolating cock and using the precision pressure reducing device set the supply pressure to (6 ± 0,15) bar as shown on the supply pressure t
