What is ISO 55119-2014?

The ISO 55119-2014 standard is a technical specification developed by the International Organization for Standardization (ISO). This standard provides guidelines and requirements for the design, development, and testing of safety-related electronic systems used in machinery. It aims to ensure that these systems are reliable and meet certain safety criteria, ultimately enhancing the overall safety and performance of machinery across various industries.

Key Requirements of ISO 55119-2014

ISO 55119-2014 outlines several key requirements that need to be met when designing and implementing safety-related electronic systems. These include:

Safety functions: The standard emphasizes the need to define and evaluate the safety functions and their performance levels. Safety functions refer to the actions taken by the system to prevent or mitigate risks in machinery operation.

Hazard analysis: A thorough hazard analysis must be conducted to identify potential risks associated with the machinery and its systems. This analysis helps in determining the required safety functions and their performance levels.

Reliability: The standard highlights the importance of designing reliable electronic systems. This includes specifying maximum allowable failure rates, conducting failure analysis, and implementing appropriate measures to reduce failures and maintain system reliability.

Validation and verification: ISO 55119-2014 requires validation and verification activities throughout the system life cycle. This ensures that the safety-related electronic systems meet the specified safety requirements and perform as intended.

Benefits and Applications

Implementing ISO 55119-2014 brings several benefits in terms of safety, performance, and compliance. Some key advantages of following this standard include:

Enhanced safety: By adhering to the requirements of ISO 55119-2014, manufacturers can improve the safety of their machinery by implementing reliable safety functions and ensuring that potential risks are adequately addressed.

Industry compliance: Many industries have specific regulatory requirements for safety-related systems. Compliance with ISO 55119-2014 helps manufacturers meet these industry standards and regulations.

Improved performance: Designing safety-related electronic systems according to the standard's guidelines ensures dependable performance, reducing the chances of system failures and improving overall operational efficiency.

Market advantage: Companies that comply with ISO 55119-2014 demonstrate their commitment to safety and quality, which can give them a competitive edge in the market.
