Safety of Machinery - Safety-Related Parts of Control Systems - Part 1: General Principles for Design
Also Known As:
ISO 13849-1:2015 is a standard that provides safety requirements and guidelines for the design and integration of safety-related parts of control systems (SRP/CS), including software design. It specifies characteristics and performance levels required for safety functions in high demand and continuous mode applications, irrespective of the type of technology or energy used in machinery.
This standard does not specify the specific safety functions or performance levels to be used in a particular case, but rather focuses on the design principles and requirements for SRP/CS using programmable electronic systems. It does not provide specific requirements for the design of products that are parts of SRP/CS, but the principles outlined, such as categories or performance levels, can be applied.
The standard emphasizes the importance of referring to applicable International Standards, such as ISO 13851, ISO 13856-1, and ISO 13856-2, for the design of specific products like relays, solenoid valves, and motor control units that are parts of SRP/CS.
Note that the requirements for programmable electronic systems in this standard are compatible with the methodology for designing safety-related electrical, electronic, and programmable electronic control systems for machinery outlined in IEC 62061. Additionally, the standard references IEC 61508-3 for safety-related embedded software for components with PLr = e (required performance level).
