-
the cabin vertical speed is 0. On the pressure indicator:

-
the cabin pressure is value A (Pamb + 280 mbar (4.06 psi)).

On the pressure indicator:

-
the cabin pressure increases to value

B (Pamb + 580 mbar (8.41 psi)). On the vertical speed indicator:

-
the cabin vertical speed must not be more than 500 ft.min (152.39 m.min).

-
the cabin vertical speed is 0.

R  pressure stable at value B (Pamb 
R  + 580 mbar (8.41 psi)). 
R 
R  6. On the AIR COND panel 30VU: 
R  - release the PACK 1 pushbutton 
R  switch. 
R  On the CABIN PRESS section of the 
R  panel 25VU: 
R  - with the MAN/V/S CTL switch, 
R  keep the pressure stable at 
R  value B (Pamb + 580 mbar (8.41 
R  psi)). 
R  7. On the CABIN PRESS section of the 
R  panel 25VU: 
R  - with the MAN/V/S CTL switch in 
R  DN position, fully close the 
R  outflow valve. 
R  On the AIR COND panel 30VU: 
R  - release the PACK 2 pushbutton 
R  switch when the outflow valve 
R  is closed. 
R 
R  8. Monitor the pressure decrease: 
R  - at value C (Pamb + 560 mbar 
R  (8.12 psi)), start the 
R  stop-watch. 
R  - at value D (Pamb + 550 mbar 
R  (7.97 psi)), stop the 
R  stop-watch and write the time. 
R  9. Calculate the leakage rate: 
R  - leakage rate = (value C) -
R  (value D) / time 
R  The leakage rate is permitted 
R  if less than 0.64 mbar/s (0.56 
R  PSI/min) 
R  On the AIR COND panel 30VU: 
R  - push the PACK 1 and PACK 2 
R  pushbutton switches (the OFF 
R  legend is off). 

On the pressure indicator:
-
the cabin pressure is value B (Pamb + 580 mbar (8.41 psi)).

On the AIR COND panel 30VU:

-
the OFF legend of the PACK 1

pushbutton switch comes on. On the vertical speed indicator:

-
the cabin vertical speed is 0. On the pressure indicator:

-
the cabin pressure is value B (Pamb + 580 mbar (8.41 psi)).

On the lower ECAM display unit, on the CAB PRESS page:

-
the outflow valve is in the fully

closed position. On the AIR COND panel 30VU:

-
the OFF legend of the PACK 2

pushbutton switch comes on. On the pressure indicator:

-
the cabin pressure indication decreases.

On the vertical speed indicator:
-the cabin vertical speed must not be
more than 500 ft.min (152.39 m.min). On the pressure indicator:

 -------------------------------------------------------------------------------ACTION RESULT
 -------------------------------------------------------------------------------On the CABIN PRESS section of the - the cabin pressure indication panel 25VU: decreases to the external ambient
 -with the MAN V/S CTL switch,  pressure.
 decrease the cabin pressure
 until you get a differential
 pressure of 0 psi.

 NOTE : The cabin vertical speed
____
 must not be more than 500
 ft.min (152.39 m.min).

 10. Wait until the cabin is fully
 depressurized then fully open
 the outflow valve.
