What is ISO-TR 13749-2019

ISO-TR 13749-2019, also known as "Safety of machinery - Safety-related parts of control systems", is an international technical report developed by the International Organization for Standardization (ISO). It provides guidance and recommendations for the design and implementation of safety-related control systems in machinery.

Understanding Safety-related Parts

In order to comprehend the significance of ISO-TR 13749-2019, it is essential to understand what safety-related parts of control systems are. These parts refer to the components responsible for ensuring the safe operation of a machine or system. They include sensors, logical systems, actuators, and other control devices that predict, prevent, or reduce hazards.

The Importance of ISO-TR 13749-2019

ISO-TR 13749-2019 plays a crucial role in promoting safety in industrial environments. By providing systematic approaches and guidelines for the design and integration of safety-related control systems, it helps manufacturers and designers enhance the reliability and functionality of their machinery. Compliance with ISO-TR 13749-2019 ensures that safety risks associated with the operation of machinery are adequately addressed.

Key Elements of ISO-TR 13749-2019

ISO-TR 13749-2019 consists of several key elements that contribute to its comprehensive framework. These elements include the analysis of the architecture, performance level (PL) determination, and validation of safety requirements. The report also outlines methods for evaluating diagnostic coverage (DC), common cause failures (CCF), and the overall performance of safety-related control systems.
