EC marking of the machine by the machine manufacturer
Scope
The scope of this section is to provide information on how to meet the
requirements of the machines Directive for SRP/CS in a machine that uses
safety functions of a drive.
Nomenclature
 SRP/CS . S afety- R elated P arts of C ontrol S ystems.
Defined by EN ISO 13849.
 SRECS . S afety- R elated E lectrical C ontrol S ystems.
Defined by IEC/EN 62061.
Note that both terms are practically equivalent.
Harmonized standards for SRP/CS
The simplest way to meet the requirements of the machines Directive
pertaining to SRP/CS is to comply with the aforementioned standards. The
standard EN ISO 13849-1:2015 and its PL are often used.
EC marking of the whole machine. Specific ·C· standards
For some types of machines, there are harmonized specific ·C· standards.
The scope of the ·C· standards is the EC marking of the whole machine. For
SRP/CS, the ·C· standards could refer to EN ISO 13849 and/or IEC 62061.
Example:
ISO 23125:2010 Machine tools - Safety - Turning machines.
For the SRP/CS, it refers to the ISO 13849-1:2015
