A.1 Complete data - all relevant failures and accumulated
    test times for type I test, T* = 1000 h, N = 52
A.2 Grouped data for example 3, derived for table A.1
A.3 Complete data for projected estimates in example 4 -
    all relevant failures and accumulated test times;
    T* = 4000 h, N = 45,KA = 13,KB = 32,I = 16
A.4 Distinct types of category B failures, from table
    A.3, with failure times, time of first occurrence,
    number observed and effectiveness factors

    failure based on data of table A.1 with power law
    model
A.2 Observed and estimated accumulated failures/
    accumulated test time based on data of table A.2
    with power law model

Gives models and numerical metods for reliability growth assessments based on failure data from a single system that were generated in a reliability improvement programme.
