Let F be a life distribution with survival function and finite mean . The scaled total time on test transform is defined was introduced by Barlow and Campo (1975) as a tool in the statistical analysis of life data. The aging properties GHNBUE can be translated to properties of by and the properties of . Two Test statistics for testing exponentiality against GHNBUE (GHNWUE) are proposed. The distributions of the test statistics are investigated for small statistics sample. The powers of theses tests are simulated by simulation when the sample size is n=10 , 20 and 30 .
