What is ISO 13849-2:2019?

ISO 13849-2:2019 is the international standard for safety of machinery in relation to the design and integration of safety-related parts of control systems. It provides guidelines for the application of ISO 13849-1, which specifies general principles and terminology for achieving safety in machinery.

Understanding the Purpose of ISO 13849-2

The primary goal of ISO 13849-2 is to assist manufacturers in designing and evaluating machinery, ensuring that safety requirements are met throughout the entire lifecycle of a machine. This standard outlines the steps and processes needed to achieve performance levels required for each safety-related function within a control system.

Key Requirements of ISO 13849-2

ISO 13849-2 identifies several key requirements that manufacturers must meet to comply with safety standards. Firstly, it emphasizes the need for a thorough understanding of the entire machine, including its intended use and potential hazards. Manufacturers must conduct a comprehensive risk assessment to identify safety functions and define their required performance levels.

Additionally, ISO 13849-2 highlights the importance of using proven components and following established design principles. The standard calls for careful consideration of diagnostic coverage, fault tolerance, and systematic capability during the design and implementation stages. Measures to prevent common-cause failures and achieve a safe state also play a crucial role in meeting ISO 13849-2 requirements.

Benefits and Application of ISO 13849-2

Implementing ISO 13849-2 offers numerous benefits to both manufacturers and end-users. By adhering to this standard, manufacturers can ensure the safety and reliability of their machinery, minimizing the risk of accidents and injuries. Compliance with ISO 13849-2 also enhances a company's reputation by demonstrating its commitment to maintaining high safety standards.

This standard is widely applicable across various industries, including manufacturing, construction, and automation. It provides a structured framework for the design and assessment of control systems, regardless of the complexity or size of the machinery involved. ISO 13849-2 ensures that safety remains a top priority throughout the entire lifecycle of a machine, from design and production to operation and maintenance.

In conclusion, ISO 13849-2:2019 is an essential international standard that sets guidelines for the design and integration of safety-related parts of control systems in machinery. By adhering to the requirements outlined in this standard, manufacturers can ensure the safety, reliability, and performance of their machinery, minimizing risks and accidents. Compliance with ISO 13849-2 not only protects workers but also enhances a company's reputation and credibility in the market.
