As the service conditions for non-metallics becomes ever more challenging, their reliability and fitness for service evaluation requires more refined levels of testing. For elastomers used in HPHT sour conditions, the need to evaluate their ability to continue to seal requires testing that closer represents them as an elastomer seal and not as an elastomer material. This paper discusses new methods to test new techniques for the use of sour gas to conduct rapid decompression testing and new functional testing techniques to measure their ability to seal. The increased use of composite materials in more aggressive service has required new evaluation approaches to be developed and new standards written to match. This paper also discusses these new test methods for testing at a material and a pipe level within these standards.
