NORSOK Approved Materials

Materials Certified to NORSOK Industry Standards

NORSOK standards are an internationally recognised set of testing methodologies developed by the Norwegian Petroleum industry. The M-710 standard defines requirements for critical polymeric seals, seats, and back-up materials for permanent subsea use. The standard also applies to topside valves in critical gas systems.

In today’s Oil and Gas industry, the application environments are constantly changing with increasing demands to improve seal elastomer performance. The industry has established testing standards for sealing materials typically used in applications such as subsea control systems, valves, and drilling systems within critical environments.
