GB/T 41295.2-2022 Translated English of Chinese Standard (GB/T41295.2-2022, GBT 41295.2-2022): Application guide of functional safety - Part 2: Design and realisation
https://www.chinesestandard.net, 2022 M08 21 - 32 pages
This document provides guidelines for the design and realisation of functional safety systems, including safety sensors, safety logic controllers, safety communication buses, and safety actuators. This document applies to the team for functional safety system research and development (e.g., manufacturer) to give normative guidance on the development of safety products that meet the appropriate safety integrity capabilities; it is used, as a reference, by system integrators, evaluation agencies and users for the selection and evaluation of appropriate functional safety systems.
