This part of IEC 63164 provides guidance on the assurance of reliability data of automation devices. If the source of this data is calculation, guidance is given on how to specify the methods used for this calculation. If the source is from observation of devices in the field, guidance is given on how to describe these observations and their evaluations. If the source is the outcome of laboratory tests, guidance is given on how to specify these tests and the conditions under which they have been carried out.<\/p>\n
This document defines the form to present the data.<\/p>\n
The components considered in this document are assumed not to need any break-in phase before full range usage.<\/p>\n
When devices are used for functional safety application, the requirements of IEC 61508 (all parts) and related standards are considered.<\/p>\n
