The application areas of EN ISO 13849-1, EN 62061, and EN 61508 are very similar. To
help users make an appropriate decision, the IEC and ISO associations have specified the
application areas of both standards in a joint table in the introduction to the standards. EN
ISO 13849-1 or EN 62061 should be applied depending on the technology (mechanics,
hydraulics, pneumatics, electrics, electronics and programmable electronics), risk
classification and architecture.

"X" indicates that the point is covered by this standard.
Comment 1:
Designated architectures are described in Annex B of EN ISO 13849-1 and provide a simplified basis for the quantification.
Comment 2:
For complex electronics: Using designated architectures in compliance with EN ISO 13849-1 up to PL = d or every archi-
tecture in compliance with EN 62061.
Comment 3:
For non-electrical systems: Use components that comply with EN ISO 13849-1 as sub-systems.
8.1.2.4
DIN EN ISO 13849-1
A qualitative analysis according to DIN ISO EN 13849-1 is not sufficient for modern control
systems due to their technology. Among other things, DIN EN ISO 13849-1 does not take
into account time behavior (e.g. test interval and/or cyclic test, lifetime). This results in the
probabilistic approach in DIN EN ISO 13849-1 (probability of failure per unit time).
DIN EN ISO 13849-1 takes into account complete safety functions and all the devices
required to execute these. With DIN EN ISO 13849-1, safety functions are investigated from
the qualitative perspective as well as the quantitative perspective. Performance levels (PL),
which are based on the categories, are used. The following safety-related characteristic
quantities are required for devices/equipment:
● Category (structural requirement)
● PL: Performance level
