Description
Classification of the safety-related parts of a control system in respect of
their resistance to faults and their subsequent behavior in the fault condition,
and which is achieved by the structural arrangement of the parts, fault detec-
tion and/or by their reliability. The categories are: B, 1, 2, 3 and 4. (EN ISO
13849-1)
Common cause failure (EN ISO 13849-1)
Diagnostic coverage (EN ISO 13849-1)
Emergency stop
Physical size of the drive or power module
Hardware fault tolerance (IEC 61508)
Insulated gate bipolar transistor
Average probability of dangerous failure on demand (IEC 61508)
Average frequency of dangerous failures per hour (IEC 61508)
Performance level. Levels a...e correspond to SIL (EN ISO 13849-1)
Systematic capability (IEC 61508)
Safety integrity level (1...3) (IEC 61508, IEC 62061, IEC 61800-5-2)
Maximum SIL (level 1...3) that can be claimed for a safety function or subsystem
(IEC/EN 62061)
Safe torque off (IEC/EN 61800-5-2)
Proof test interval. Defines the probabilistic failure rate (PFH or PFD
the safety function or subsystem. Performing a proof test at a maximum in-
terval of T
is required to keep the SIL capability valid. The same interval must
1
be followed to keep the PL capability (EN ISO 13849) valid. Note that any T
values given cannot be regarded as a guarantee or warranty.
