STO
Proof test interval.
T

is a parameter used to define the
probabilistic failure rate (PFH or PFD) for the safety function or
subsystem. Performing a proof test at a maximum interval of
T
1
is required to keep the SIL capability valid. The same interval must
be followed to keep the PL capability (EN ISO 13849) valid.
