We study the problem of testing for exponentiality against decreasing variance residual lifetime. We exploit properties of life distributions with decreasing variance residual lifetime and construct a new nonparametric test (U-test). Pitman's asymptotic relative efficiency (PAE) is used to assess the performance of the test. Calculations show that our test is comparable with, and in some cases better than, other available tests. Then we analyse the power of the test for some distributions. The outcomes of numerical simulation are presented as an illustration for the proposed test. © 2008 Nova Science Publishers, Inc.
