In 2023, the International Organization for Standardization (ISO) released a new edition of ISO 13849-1, the fundamental standard for evaluating the safety of complex machine control systems. This update introduces key changes aimed at enhancing functional safety and providing clearer, internationally unified requirements for manufacturers and engineers working with safety-related control systems.
ISO 13849-1 is a basic functional safety standard that defines the requirements for designing and assessing the safety of control systems used in machinery. The standard focuses on:
- Determining the required Performance Level (PL)
- Identifying safety-related control system parts
- Implementing effective safety functions
By adhering to this standard, manufacturers and safety professionals can ensure that machines operate safely, reducing the risk of failure and improving overall workplace safety.
The latest edition of ISO 13849-1 includes several crucial changes that impact the assessment and implementation of machine control safety. Some of the notable updates include:
- Refined methodology for Performance Level (PL) determination – Enhancing clarity on how to assess the required safety performance for machinery components.
- Improved definitions and terminology – Aligning with international standards to eliminate ambiguity.
- Clarifications on safety-related control parts (SRP/CS) – Providing more detailed guidance on identifying and assessing safety-critical elements.
- Updated requirements for software validation – Strengthening verification processes to ensure the reliability of safety functions.
These changes make it easier for engineers and manufacturers to comply with safety regulations while maintaining high levels of machine reliability and efficiency.
