Standards and regulations
10.2 Safety of machinery in Europe
hydraulics, pneumatics, electrics, electronics, programmable electronics), risk classification
and architecture.
Standard IEC 61800-5-2:2007 is applicable for variable-speed electric drives with integrated
safety functions. IEC 61800-5-2 defines requirements and gives recommendations for
designing and developing, integrating and validating safety-related applications regarding
their functional safety. IEC 61800-5-2 is applicable for adjustable speed electric power drive
systems, which are handled in other parts of IEC 61800 standards.
Systems for executing safety-related control
functions
A Non-electrical (e.g. hydraulic, pneumatic)
B Electromechanical (e.g. relay and/or basic
electronics)
C Complex electronics (e.g. programmable elec-
tronics)
D A standards combined with B standards
E C standards combined with B standards
F C standards combined with A standards
or
C standards combined with A standards and B
standards
"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.
