GB/Z 29638-2013

This standard provides guidance on applying functional safety principles to electrical, electronic, and programmable electronic systems, specifically clarifying the relationship between functional safety concepts and the GB/T 20438 series (the Chinese adoption of IEC 61508). It is used in manufacturing and industrial automation contexts to help engineers and procurement professionals understand how to design, assess, and procure safety-related systems that mitigate risks in machinery and process control applications. The standard serves as an introductory overview for implementing safety lifecycle requirements across various industries where system failures could lead to hazards.
