GB/T 36245-2018

This standard provides a systematic methodology for allocating reliability targets to subsystems and components within industrial process measurement and control instruments, such as pressure transmitters, flow meters, and temperature sensors. It is applied during the design and development phase in manufacturing industries, including petrochemical, power generation, and metallurgy, to ensure that overall system reliability requirements are met through quantitative distribution of failure rate goals. The guide supports engineers in balancing cost, performance, and reliability across complex instrumentation systems used in automated process control environments.
