Methodology Investigation. Intensive Tropic Function Testing.
Abstract
USATTC conducted a methodology investigation in the humid tropics of the Canal Zone from March 1976 through March 1977. The objective was to determine whether intensive function testing or simulated tactical function testing can produce tropic-related effects similar to effects found after storage, while reducing the length of time typically required for tropic storage test designs. The US Army's 1.5-kilowatt AC generator was selected to evaluate three alternative test designs to determine whether one or more designs would accelerate tropic materiel defects and thereby shorten test time. The test designs were: intensive functioning, simulated tactical use and storage. The last is the prevailing design used by USATTC in tropic tests. RAM data were collected on five generators in each of the three design groups. It was concluded that: (1) The intensive functioning test design was less severe than either the storage or simulated tactical use test designs, (2) More valid RAM estimates can be obtained in the tropics when test designs incorporate expected field use patterns, (3) The generators of the storage test design exhibited no tropic storage-related effects; therefore, no conclusion could be drawn concerning the equivalence of the test designs in producing tropic storage-related effects.
