What is BS EN 61508:2018?

BS EN 61508:2018 is an international standard that provides guidelines for the functional safety of electrical, electronic, and programmable electronic safety-related systems. It sets out industry best practices for ensuring that these systems can reliably carry out their intended safety functions to protect people, property, and the environment.

Why is BS EN 61508:2018 important?

In today's complex technological landscape, many systems rely on electronics and software to perform critical safety functions. These systems can be found in a wide range of industries, including automotive, aerospace, nuclear power, and healthcare. The importance of ensuring the safety and reliability of these systems cannot be overstated, as malfunctions could have catastrophic consequences.

BS EN 61508:2018 helps organizations in developing, implementing, and maintaining safety systems by providing clear guidelines and requirements. By adhering to this standard, companies can demonstrate that they are taking appropriate measures to assess and mitigate safety risks, ultimately ensuring the safety of their products and processes.

The key elements of BS EN 61508:2018

BS EN 61508:2018 consists of several parts that together form a comprehensive framework for functional safety management. The standard covers various aspects, including system design, development, verification, validation, and ongoing maintenance.

One of the key elements of BS EN 61508:2018 is the concept of Safety Integrity Level (SIL). SIL is a measure of the effectiveness of a safety function in reducing the risk of hazardous events. The standard provides guidelines for determining the required SIL for a given safety function and specifies the techniques and methods to achieve it.

The standard also emphasizes the importance of systematic safety assessments throughout the entire lifecycle of a safety-related system. It requires organizations to perform hazard and risk analysis, as well as to conduct functional safety assessments to ensure that the system meets the specified safety requirements.

Conclusion

BS EN 61508:2018 plays a crucial role in ensuring the functional safety of electrical, electronic, and programmable electronic safety-related systems. By following the guidelines set out in this international standard, organizations can minimize the risks associated with these systems and prevent potential accidents or failures.

Adopting BS EN 61508:2018 not only helps companies protect people, property, and the environment, but it also enhances their reputation by demonstrating their commitment to safety. As technology continues to advance, conforming to internationally recognized safety standards becomes increasingly important for organizations operating in safety-critical industries.
