Twelve containers, proposed for shippingstorage of external fuel tanks, were subjected to outdoor storage environmental tests. The external fuel tanks were totally encapsulated in 2.0 p.c.f. rigid polyurethane foam. Opening of container was accomplished by using a tear wire prepositioned on the fuel tank prior to total encapsulation. From the results obtained it was concluded that the rigid polyurethane foam gives adequate protection to external fuel tanks during unprotected storage and rough handling for a period of 3 years. Also, a tear wire opening of the container at an angle down from the center line of the external fuel tank will provide a good closure without the use of a sealant.
