This paper presents the comments of the author on the work of Mr. Cooper (2008) by pointing out two concerns: First, the discussion of burn-in, and the tone of one of the major references (van der Pol et al. (1998)), would lead one to believe that burn-in is the only screen currently or commonly used to identify infant mortality or to detect substandard components. Second, it appears that Cooper's assumptions regarding acceleration factors may be suitable in cases where burn-in is the only screen in use, where the defects are susceptible to the burn-in stresses, and where only a limited number of different failure modes are present.
