STANDARDIZATION PROGRAM ON SHELF AGING OF SYNTHETIC AND NATURAL RUBBER MATERIALS.
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)
