scope:

To determine the effect on the connector of prolonged exposure to conditions of high humindity at various temperatures. Two conditions of test are provided as follows: Steady State Test - Used to evaluate the hygroscopic nature of insulating materials as evidenced by deteriorated physical properties (dimensions, mechanical strength, etc.) or degraded electrical properties (e.g. insulation resistance). Humidity-Temperature Cycling Test - Used to evaluate the effectiveness of seals and gaskets in the presence of a pressure differential induced by varying temperatures; the corrosion resistance of metals and finishes exposed to alternate periods of condensation and drying; and the hygroscopic nature of insulating materials, with any degradation accelerated by the "breathing" action imposed by varying temperatures. Optional exposures to sub-freezing temperatures and to mechanical vibration exaggerate any structural deterioration of insulating materials.
