This article described the implementation of several new preconditioning capabilities at the outside laboratory. A temperature shroud was developed that was small and could easily be placed onto or taken off of the shaker. This shroud, attached to a portable temperature conditioner, provides a portable system that should be able to meet future temperature test requirements. The conditioner was modified by adding a dry-nitrogen purge option. By injecting dry nitrogen into the conditioner air flow, the relative humidity inside the shroud can be kept well below the 15 percent maximum requirement. Finally, since the shock requirements couldn't be met on the slip plate with the weight of the fixturing and shroud, a new fixture that holds the Test Bed in the vertical position on the shaker was developed. An Eigen frequency analysis was conducted to determine the optimum number of and placement of the fixture supporting ribs.
