CEN/TC114/WG6 have used a proof test interval (mission time) of 20 years to support the estimation of mean time to dangerous failure (MTTFD) for the realization of designated architectures in Annex B of prEN ISO 13849-1. Therefore, it is recomme

28、nded that SRECS designers endeavour to use a 20 year proof test interval. It is acknowledged that some subsystems and/or subsystem elements (e.g. electro-mechanical components with high duty cycles) will require replacement within the SRECS proof test interval. Proof testing involves detailed and co

29、mprehensive checks that can, in practice, only be performed when the SRECS and/or its subsystems has been designed to facilitate proof testing (e.g. dedicated test ports) and provided with necessary information (e.g. proof test instructions).
