Functional Safety of Machinery - by Marco Tacchini (Hardcover)

Book Synopsis

Enables readers to understand ISO 13849-1 and IEC 62061 standards and provides a practical approach to functional safety in machinery design

Functional Safety of Machinery: How to Apply ISO 13849-1 and IEC 62061 introduces functional safety of machinery as a single unified approach, despite the existence of two standards. Aligning with the latest updates of ISO 13849-1 and IEC 62061, the book explains the intent behind the standards and the mathematical basis on which they are written, details the differences between the two standards, and prescribes ways to put them into practice.

To aid in seamless reader comprehension, detailed examples are included throughout the book which walk readers through concepts like Random and Systematic Failures, High and Low demand mode of operation, Diagnostic Coverage, and Safe Failure Fraction. Other sample topics covered within the book include:

• Basics of reliability engineering and functional safety
• Roles of the standards in the design and evaluation of safety functions
• Description of the Main Parameters used in the two standards
• How to deal with Low Demand Safety Systems
• The Categories of ISO 13849-1 and the Basic Subsystem Architectures of IEC 62061
• How Categories and Architectures can be validated

Machinery design engineers, machinery manufacturers, and professionals in system and industrial safety fields can use this book as a one-stop resource to understand the specifics and applications of ISO 13849-1 and IEC 62061.
