A method of testing the sensitivity of electrical and mechanical components or assemblies to noncorrosive environmental pollutants is described. The test involves exposing the assemblies to relatively high concentrations of pollutant gases in order to accelerate the test. A test procedure and a design for the test chamber are described. The method is illustrated for testing the sensitivity of rigid disk drives to several common noncorrosive office pollutants. For this test, the pollutants of interest are organosilicones, nicotine, dioctyl-phthatlate, and diethylhexyl-phthalate. The test apparatus is illustrated in the figure. The disk drives are placed in an airtight test chamber. Cables are run into the chamber from a programmable power supply connected to an IBM PC-XT and Interface Controller.
