Claim 7:
8. The method according to claim 1, further comprising:
a) apart from the determined time at which the second partial stroke test can be carried out, specifying further starting conditions and at least one abort criterion for the second partial stroke test;
b) checking the further start conditions before the second partial stroke test is performed;
c) if the further start conditions are not fulfilled, not performing the second partial stroke test and repeating the determination of the time at which the second partial stroke test can be performed and the checking of the further start conditions;
d) if a time at which the second partial stroke test can be performed has been determined and the further start conditions are fulfilled, starting the second partial stroke test at the determined time;
e) during the second partial stroke test, continuously monitoring movement of the valve member and the state or property of at least one of the plant, the process, and the process medium,
f) aborting the second partial stroke test as soon as at least one of the abort criteria is met;
g) registering the second partial stroke test as a successful second partial stroke test if the valve member has reached a stroke which is greater than the first stroke;
h) registering the second partial stroke test as a successful first partial stroke test if the valve member has reached a stroke equal to the first stroke;
i) registering the second partial stroke test as unsuccessful if the valve member has reached a stroke that is less than the first stroke; and
j) continuing the method with step b.
