GB/T 20438.6-2006

This standard provides application guidelines for implementing the functional safety requirements of GB/T 20438.2 (hardware) and GB/T 20438.3 (software) in electrical, electronic, and programmable electronic safety-related systems. It is used by engineers and safety assessors in industries such as manufacturing, process control, and machinery to correctly apply risk reduction measures and achieve specified Safety Integrity Levels (SIL). The standard supports consistent interpretation and practical execution of the core functional safety framework during system design, verification, and validation.
