Short name: |
R(t1, t2) |
Definition: |
probability of performing as required for the time interval (t1, t2), under given conditions |
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. |
