1.1 This standard ( Part VI) gives recommended numerical methods for testing the statistical validity of the constant failure rate assumption underlying the methods used in IS: 8161 (Part IV)〓 and IS: 8161 (Part VII)-1977〓.
1.2 Recommendations are given for action to be taken in case the assumption is rejected. If stated in the detailed reliability test specification, one of these tests shall be applied before a conclusion is made from reliability testing of failure rate or mean time between failures.
