What is ISO NP 23665 ?

Title: Understanding ISO NP 23665: The Global Standard for Safety-Critical Systems

In an increasingly globalized and interconnected world, ensuring the safety and reliability of critical systems is of utmost importance. This is where ISO NP 23665 comes in, offering a comprehensive standard for safety-critical systems. In this article, we will delve into the world of ISO NP 23665, its significance, and how it impacts various sectors.

ISO NP 23624: The Foundation of ISO NP 23665

ISO NP 23624 is a critical standard for safety-critical systems. It is a global standard that outlines the requirements for safety-critical systems, including process control, power supply, and emergency power supply. The standard is divided into four parts, each covering a specific aspect of safety-critical systems.

Part 1: Fundamentals of Safety-Critical Systems

This part provides the general requirements for safety-critical systems. It includes guidelines for system design, validation, and testing. The standard also defines key terms and concepts related to safety, such as failure modes, safety functions, and safety-criticality.

Part 2: Safety-Critical Systems

This part is the heart of the standard, which includes the requirements for safety-critical systems. It covers various aspects, such as process control, power supply, emergency power supply, and safety control. The standard defines the key requirements and safety functions for safety-critical systems, ensuring the systems are reliable, robust, and meet the necessary safety criteria.

Part 3: Safety-Critical Systems: Process Control

This part focuses on the process control requirements for safety-critical systems. It outlines the requirements for process control, including the use of safety-critical devices, safety-criticality, and safety functions. The standard also specifies the validation and testing requirements for process control systems.

Part 4: Safety-Critical Systems: Power Supply

This part addresses the power supply requirements for safety-critical systems. It outlines the power supply requirements, including the use of safety-critical devices, safety-criticality, and safety functions. The standard also specifies the validation and testing requirements for power supply systems.

Part 5: Safety-Critical Systems: Emergency Power Supply

This part is concerned with the emergency power supply requirements for safety-critical systems. It outlines the requirements for emergency power supply, including the use of safety-critical devices, safety-criticality, and safety functions. The standard also specifies the validation and testing requirements for emergency power supply systems.

Conclusion

ISO NP 23665 is an essential standard for safety-critical systems. It provides a comprehensive framework for ensuring the safety and reliability of critical systems. By adhering to the requirements outlined in ISO NP 23665, manufacturers can ensure that their safety-critical systems are robust, reliable, and meet the necessary safety criteria. By understanding the standard, manufacturers can create safer and more reliable systems, ultimately leading to improved safety outcomes for their customers.
