DNV-RP-B301 Inspection and evaluation of non-metallic seals

This recommended practice (RP) describes a procedure for inspecting, testing and evaluating non-metallic seals used in service.

The objective of this RP is to improve equipment integrity through the correct seal and sealing material being selected for long-term no-leak service. The RP can further be used to optimize service intervals and life extensions by documented field experience.
