ISO 13849-1:2023 Requirements Overview
SN EN ISO 13849-1:2023
Sicherheit von Maschinen - Sicherheitsbezogene Teile von Steuerungen - Teil 1: Allgemeine Gestaltungsleitsätze (ISO 13849-1:2023)
Safety of machinery - Safety-related parts of control systems - Part 1: General principles for design (ISO 13849-1:2023)
This document specifies a methodology and provides related requirements, recommendations and guidance for the design and integration of safety‐related parts of control systems (SRP/CS) that perform safety functions, including the design of software. This document applies to SRP/CS for high demand and continuous modes of operation including their subsystems, regardless of the type of technology and energy (e.g. electrical, hydraulic, pneumatic, and mechanical). This document does not apply to low demand mode of operation. NOTE 1 See 3.1.44 and the IEC 61508 series for low demand mode of operation. This document does not specify the safety functions or required performance levels (PLr) that are to be used in particular applications. NOTE 2 This document specifies a methodology for SRP/CS design without considering if certain machinery (e.g. mobile machinery) has specific requirements. These specific requirements can be considered in a Type‑C standard. This document does not give specific requirements for the design of products/components that are parts of SRP/CS. Specific requirements for the design of some components of SRP/CS are covered by applicable ISO and IEC standards. This document does not provide specific measures for security aspects (e.g. physical, IT-security, cyber security). NOTE 3 Security issues can have an effect on safety functions. See ISO/TR 22100-4 and IEC/TR 63074 for further information.
SN EN ISO 13849-1:2023 is a standard published by the International Organization for Standardization (ISO) focusing on the safety-related parts of control systems in machinery. It outlines essential requirements for design and integration to ensure safety compliance across various industries.
=== SECTION 1 ===
Purpose and objectives
The primary purpose of ISO 13849-1:2023 is to provide a framework for the design and integration of safety-related parts of control systems (SRP/CS) in machinery. This standard aims to enhance the safety of machinery by ensuring that control systems operate effectively and reliably under specified operational conditions. It emphasizes risk assessment and the need for appropriate safety measures to mitigate potential hazards associated with machinery operation. By adhering to these guidelines, manufacturers can ensure compliance with safety regulations, ultimately protecting operators and reducing the risk of accidents.
=== SECTION 2 ===
Scope: who must comply
ISO 13849-1:2023 applies to manufacturers and designers of machinery across a wide range of industries, including manufacturing, construction, and automation. It is particularly relevant for those involved in the production of machinery that incorporates safety-related control systems. Companies must comply with this standard to meet the Environment, Health & Safety (EHS) regulations and ensure that their machinery is safe for operators and users. This includes organizations of all sizes that design, manufacture, or integrate controls into machinery, highlighting the standard's critical role in fostering a safe working environment.
=== SECTION 3 ===
How SN EN ISO 13849-1:2023 relates to other standards
ISO 13849-1:2023 is closely related to several other standards, enhancing its relevance in the field of functional safety. Key related standards include:
- IEC 61508: This standard provides a framework for the functional safety of electrical and electronic systems, complementing the requirements of ISO 13849-1:2023.
- ISO/TR 22100-4: This technical report addresses the interaction between safety and security in the design of machinery, offering guidance that aligns with the principles outlined in ISO 13849-1:2023.
- IEC/TR 63074: This technical report discusses the integration of cybersecurity into functional safety, further emphasizing the need for holistic safety measures in machinery design.
