Conventional testing of seal materials in high temperature, high pressure, chemically aggressive environments provides little information about the physical and mechanical characteristics of the seal material in the service environment. The effects of exposure are deduced by measuring changes in properties after exposure. A new technique for evaluating the sealing characteristics of elastomers during exposure to these environments has been developed. The stress/strain characteristics and the stress relaxation or the creep of seal materials are monitored continuously during exposure.
