The recently-published UNE-EN ISO 13849-1:2024 standard specifies a methodology and provides requirements, recommendations and guidance related to the design and integration of safety-related parts of control systems, including software design.

It applies to safety-related parts of control systems (SRP/CS) for high and continuous operation modes, regardless of the type of technology and energy (electrical, mechanical, hydraulic, pneumatic, etc.)

This new standard includes 16 Information Annexes, including Annex F, which deals with the method for quantifying measures against common cause failures (CCF), and Annex N, on how to avoid systematic failures in software design.
