Term or abbre-
viation
Average frequency of dangerous failures per hour for the diagnostic
function of STO
IEC/EN 62061
PFH
diag
Performance level. Levels a…e correspond to SIL
EN ISO 13849-1
PL
Periodic test performed to detect failures in a safety-related system
so that, if necessary, a repair can restore the system to an "as new"
condition or as close as practical to this condition
IEC 61508, IEC 62061
Proof test
Systematic capability
IEC 61508
SC
Safe failure fraction (%)
IEC 61508
SFF
Safety integrity level (1…3)

SIL
Safe torque off
IEC/EN 61800-5-2
STO
Proof test interval.
T
1
is a parameter used to define the probabilistic
failure rate (PFH or PFD) for the safety function or subsystem. Per-
forming 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.

Mission time: the period of time covering the intended use of the safety
function/device. After the mission time elapses, the safety device must
be replaced. Note that any

values given cannot be regarded as a
guarantee or warranty.
