What is EN ISO 13849-1:2019 ?

EN ISO 13849-3:2019 is a technical standard that outlines the requirements for the safety of machinery control systems. It is designed to minimize the risk of hazardous situations and protect personnel from harm. The standard has several key components that must be followed during the design process.

The primary objective of EN ISO 13949-3:2019 is to provide guidance and requirements for designing and implementing safety functions within machinery control systems. It aims to achieve this by defining key requirements that must be met by the control system design. These key requirements are as follows:

Hazard identification: The standard requires the control system to identify potential hazards associated with the machinery. This is done by conducting a risk assessment and identifying potential risks.

Risk assessment: The standard outlines a risk assessment procedure that must be followed when designing the control system. This procedure involves identifying the potential hazards and assessing their likelihood and severity.

Safety functions: The standard defines safety functions that must be implemented to minimize the risk of hazardous situations. These functions include emergency stop, safety interlock, and safety monitoring.

Safety assessment: The standard requires the control system to be designed to continually monitor and evaluate the safety functions. This is done by conducting regular safety checks and conducting periodic safety reviews.

Documentation: The standard requires the control system design to be documented in a written format. This documentation includes a safety plan, a hazard identification and risk assessment report, and a safety assessment report.

By following the key requirements outlined in EN ISO 13949-3:2019, manufacturers can ensure that their machinery control systems are designed and implemented to minimize the risk of hazardous situations and protect personnel from harm. This helps to ensure the safety of machinery, which is essential for the well-being of workers, the environment, and society as a whole.
