What is BS EN ISO 13849-2:2012?

BS EN ISO 13849-2:2012 is a technical standard that relates to the safety of machinery and provides guidance on the design and implementation of safety-related control systems. It is an essential document for engineers, designers, and manufacturers who are involved in developing or modifying machinery.

Understanding the Purpose of BS EN ISO 13849-2:2012

The main purpose of BS EN ISO 13849-2:2012 is to help ensure the safety of machinery by providing guidelines for achieving the required levels of functional safety. This standard outlines the principles and requirements for the design and integration of safety-related control systems within machinery.

By following the recommendations and requirements outlined in BS EN ISO 13849-2:2012, engineers and manufacturers can reduce the potential hazards associated with machinery operation and improve overall equipment safety.

Key Components of BS EN ISO 13849-2:2012

BS EN ISO 13849-2:2012 consists of several key components that contribute to the achievement of functional safety:

1. Safety functions: This standard defines safety functions as the actions taken by the machinery's control system to bring the machine into a safe state. These safety functions may involve stopping, limiting, or controlling the machinery's movement.

2. Performance levels: The standard categorizes performance levels based on the reliability and probability of dangerous failures within the safety-related control system. Engineers must select the appropriate performance level to ensure the desired level of functional safety.

3. Design considerations: BS EN ISO 13849-2:2012 provides detailed guidance on various design considerations, including the selection and validation of safety-related parts of control systems, architecture requirements, and the use of diagnostic measures to detect failures.

Implementing BS EN ISO 13849-2:2012 in Practice

Implementing BS EN ISO 13849-2:2012 requires careful planning and thorough understanding of the standard's requirements. Here are some key steps to follow:

1. Risk assessment: Conduct a comprehensive risk assessment to identify potential hazards and evaluate their severity. This will help determine the necessary performance levels for the safety-related control system.

2. System design: Based on the identified performance levels, design the safety-related control system, ensuring that all components meet the necessary reliability and safety requirements.

3. Validation and verification: Validate and verify the implemented safety-related control system to ensure it meets the specified performance levels. This may involve testing, analysis, and documentation.

4. Maintenance and monitoring: Regularly maintain and monitor the safety-related control system to ensure its continued functionality and effectiveness in mitigating risks.

In conclusion, BS EN ISO 13849-2:2012 plays a crucial role in enhancing machinery safety through the design and implementation of safety-related control systems. By following this standard, engineers and manufacturers can reduce hazards, improve functional safety, and protect users from potential accidents and injuries.
