Impact of Product Reformulation and Obsolescence on Closed Environmental Atmospheres 2002-01-2302
The materials used in closed environmental systems must be carefully chosen and tested for stability and interactions with other materials to insure the safety of crew and machinery. This process can be difficult and time consuming, but provides a finished product that meets the requirements needed. However, even minor changes in a materials composition by the vendor can have significant impact on closed environments. The US Navy has had several experiences with product reformulation or modifications that caused unexpected results.
