Metadata#
- Note
- Note 1 Given conditions include aspects that affect reliability, such as: mode of operation; stress levels; environmental conditions; and maintenance, where applicable. Note 2 It is usually assumed that the item is in a state to perform as required at the beginning of the time interval. Note 3 When t1 = 0 and t2 = t, then R(0, t) is denoted simply as R(t) and termed the reliability function, or survival function of the item. Note 4 See also reliability of an item IEV 192-01-24:2015-02.
- Remark
- See IEC 61703, Mathematical expressions for reliability, availability, maintainability and maintenance support terms, for more details.
