1.1 GB/T 20438 covers those aspects to be considered when electrical/electronic/ programmable electronic systems (E/E/PESs) are used to carry out safety functions. A major objective of this standard is to facilitate the development of the national standard in application sector by the technical committees responsible for the application sector. This will allow all the relevant factors, associated with the application, to be fully taken into account and thereby meet the specific needs of the application sector. A dual objective of GB/T 20438 is to enable the development of electrical/electronic/programmable electronic (E/E/PE) safety-related systems where national standard in application sector may not exist.
