What is EN ISO 14142-4:2021?

EN ISO 14142-4:2021 is an international standard that provides guidelines and specifications for the development and implementation of safety-related parts of control systems (SRP/CS) within machinery. It is part of a series of standards that aim to ensure the safety of machinery by addressing the potential risks associated with the use of these machines.

Understanding the Purpose of EN ISO 14142-4:2021

The main purpose of EN ISO 14142-4:2021 is to provide manufacturers, suppliers, and users of machinery with a comprehensive framework for designing, implementing, and evaluating the safety-related parts of control systems. By adhering to the requirements outlined in this standard, it becomes possible to minimize the risk of accidents and injuries caused by mechanical failure or malfunction.

EN ISO 14142-4:2021 emphasizes the importance of proper risk assessment and risk reduction measures during the design phase of machinery and control systems. It guides manufacturers in identifying hazards associated with their machines, estimating the level of risk they present, and implementing appropriate safety measures to mitigate these risks.

Key Requirements and Considerations

This standard outlines several key requirements and considerations that should be taken into account when developing safety-related parts of control systems. These include:

Defining the required performance levels (PLr) for different safety functions

Using validated methods for calculating the performance level

Integrating suitable safety measures based on identified risks

Implementing redundant systems to minimize the probability of hazardous failures

Providing clear instructions and documentation for maintenance and troubleshooting

Adhering to these requirements ensures that control systems are designed and implemented with the necessary safety measures, reducing the likelihood of accidents and injuries. It also promotes consistency in safety standards across different machinery and industries, facilitating international trade and cooperation.

Conclusion

EN ISO 14142-4:2021 is a vital standard for ensuring the safety of machinery and control systems. By following its guidelines, manufacturers can minimize the risk of accidents and protect users from potential harm. Proper implementation of this standard contributes to the overall improvement of workplace safety, making it an essential resource for both manufacturers and users of machinery.
