SN EN ISO 13849-2:2013 is an international standard that provides guidelines for validating safety-related parts of control systems in machinery. It is published by ISO and applies to organizations involved in designing, manufacturing, and maintaining machinery with safety functions.

Purpose and objectives

The primary aim of SN EN ISO 13849-2:2013 is to ensure that safety-related parts of control systems (SRP/CS) perform reliably in the context of machinery safety. This standard outlines validation procedures, emphasizing the importance of assessing whether these systems meet the required performance levels (PL) and safety integrity levels (SIL) as defined in related standards. By implementing these guidelines, organizations can effectively mitigate risks associated with machinery operations, promoting safer working environments and compliance with relevant regulations.

Scope: who must comply

SN EN ISO 13849-2:2013 applies to a wide range of industries, including manufacturing, automotive, and construction, where machinery is used. It is particularly relevant for companies that design and implement control systems that incorporate safety functions. Compliance with this standard is crucial for organizations aiming to enhance their Environment, Health & Safety (EHS) practices, as it provides a framework for evaluating the safety of machinery operations and ensuring protection for operators and the surrounding environment. Companies seeking ISO 13849-1 compliance guidelines and certification requirements will find this standard highly applicable.

How SN EN ISO 13849-2:2013 relates to other standards

SN EN ISO 13849-2:2013 is closely related to several key standards:

• ISO 13849-1: This standard outlines the overall requirements for safety-related parts of control systems, providing foundational principles that SN EN ISO 13849-2 builds upon.
• IEC 61508: A broader standard for functional safety, IEC 61508 provides a framework for assessing safety integrity levels (SIL) across various industries, complementing the specific focus of ISO 13849-2 on machinery.
• CEN and CENELEC Guidelines: These European standards set out additional compliance requirements that align with ISO standards, ensuring a unified approach to safety in machinery operations.

Revision history and current status

SN EN ISO 13849-2 was first published in 2013 by the International Organization for Standardization (ISO). The most recent revision maintains its relevance in the context of evolving technology and safety criteria in machinery control systems. Key updates in this revision include enhanced validation procedures and clarified performance level requirements, ensuring alignment with advancements in the field of functional safety. Organizations striving for ISO 13849-1 compliance will benefit from adhering to the latest guidelines established in this standard.
