What is the difference between 62061 and 13849 ?

Title: What is the difference between ISO 13849 and IEC 62061? A comparison between two important safety standards

Safety is a critical aspect of any system, including machines and their control systems. To ensure the safety and reliability of these systems, various safety standards have been developed. Two such standards are ISO 13849 and IEC 6206While they share some similarities, they have distinct differences in their scope and application. In this article, we will provide a comprehensive comparison between ISO 13849 and IEC 62061.

ISO 13849: A Functional Safety Standard

ISO 13849 is an international standard that outlines the requirements for functional safety of machinery. It is focused on ensuring the safety of machinery by ensuring that the control systems are designed to meet specific requirements. The standard specifies the functions that must be performed by the safety control systems, the interfaces between these systems, and the performance criteria that must be met.

ISO 13849 is divided into ten parts, each covering a different aspect of functional safety. These parts include:

Safety requirements for machinery – covering the overall safety of the machinery

Control functions and interfaces – specifying the functions that must be performed by the safety control systems and the interfaces between these systems

Performance requirements – specifying the criteria that must be met by the safety control systems

Test requirements – specifying the tests that must be performed to ensure the safety of the machinery

Monitoring and diagnosis requirements – specifying the methods for monitoring and diagnosing the performance of the safety control systems

Safety analysis requirements – specifying the methods for analyzing the safety of the machinery

Safety assessment requirements – specifying the methods for assessing the safety of the machinery

Safety validation requirements – specifying the methods for validating the safety of the machinery

Safety documentation requirements – specifying the requirements for the documentation of the safety of the machinery

Safety training requirements – specifying the requirements for training on the safety of the machinery.

ISO 13849 is widely recognized and respected in the industry, and it is often used as the benchmark for functional safety standards.

IEC 62061: A Safety Integrity Standard

IEC 62061 is an international standard that outlines the requirements for the integrity of safety-related systems. It is focused on ensuring the reliability and safety of systems by ensuring that the control systems are designed to meet specific requirements. The standard specifies the functions that must be performed by the safety control systems, the interfaces between these systems, and the performance criteria that must be met.

IEC 62061 is divided into ten parts, each covering a different aspect of safety integrity. These parts include:

Safety requirements for electrical systems – covering the overall safety of electrical systems

Control functions and interfaces – specifying the functions that must be performed by the safety control systems and the interfaces between these systems

Performance requirements – specifying the criteria that must be met by the safety control systems

Test requirements – specifying the tests that must be performed to ensure the reliability of the electrical systems

Monitoring and diagnosis requirements – specifying the methods for monitoring and diagnosing the performance of the safety control systems

Safety analysis requirements – specifying the methods for analyzing the safety of the electrical systems

Safety validation requirements – specifying the methods for validating the safety of the electrical systems

Safety documentation requirements – specifying the requirements for the documentation of the safety of the electrical systems

Safety training requirements – specifying the requirements for training on the safety of the electrical systems

Safety in service requirements – specifying the requirements for the electrical systems during.
