Abstract:

The U.S. Naval Applied Science Laboratory was authorized to continue the 7-yr shelf aging program to determine whether the shelf life of elastomeric end-items can be extended beyond 3 years and to determine the correlation between shelf aging and accelerated heat aging. The test program was modified to determine at 12-month instead of 6-month intervals the tensile strength, elongation, tensile product, modulus at 300 elongation and swelling ratio of the packaged and unpackaged specimens currently being subjected to shelf aging and low temperature conditioning. The samples consisted of a butadiene-styrene low temperature gasjet material, a Buna N 0-ring material, a natural rubber door hatch gasket material and a neoprene GR-T shock mount material. Author
