Case 2: Vertical mounting position test with
additional weight force suspended
1. Place the piston rod in the retracted end
position.
2. Vent the port

. The clamp is active.
3. Pressurise the cylinder in extending direc
tion at the test pressure P
A
(calculation
with piston area A for extending direction
perFig.30).
Case 3: Vertical mounting position test with
additional weight force upright
1. Place the piston rod in the advanced end
position.
2. Vent the port
2
. The clamp is active.
3. Pressurise the cylinder in retracting direc
tion at the test pressure P
A
(calculation
with piston area A for retracting direction
perFig.30).
