BS EN ISO 24508:2019 is a standard that provides guidelines for the evaluation and selection of software used in computer-based control systems. This international standard, updated in 2019, focuses on the use of software in industrial automation, process control, and related areas.
The Purpose of BS EN ISO 24508:2019
The purpose of BS EN ISO 24508:2019 is to help organizations identify and select appropriate software for their computer-based control systems. It provides guidance on evaluating the reliability, maintainability, and availability of software, as well as its functionality and performance. The standard aims to ensure that the selected software meets the necessary requirements and can be effectively integrated into the control system.
Evaluating Software Reliability
One of the key aspects covered by BS EN ISO 24508:2019 is software reliability. Reliability refers to the ability of software to perform its intended functions without failure over a specified period of time. The standard recommends conducting thorough testing and analysis to assess the reliability of software. This includes evaluating its resistance to faults, errors, and failures, as well as its ability to recover from such incidents and continue normal operation.
Maintainability and Availability Considerations
In addition to reliability, BS EN ISO 24508:2019 emphasizes the importance of maintainability and availability when selecting software for computer-based control systems. Maintainability refers to the ease with which software can be modified or repaired, while availability relates to the readiness of the software to perform its functions when required. The standard suggests evaluating factors such as documentation, support, and scalability to determine the maintainability and availability of software.
Overall, BS EN ISO 24508:2019 serves as a valuable resource for organizations involved in industrial automation and process control. By following the guidelines set forth in this standard, organizations can make informed decisions when selecting software for their computer-based control systems, ensuring reliability, maintainability, and availability.
