First issued in 1998 (hence the "98" in SP0198), the standard has been revised several times, with the latest version being . It provides a systematic, risk-based approach to mitigating CUI across the entire lifecycle of a facility—from design and construction to operation, inspection, and repair. Key Terminology Change You may also hear this referred to as NACE RP0198 (RP = Recommended Practice). In 2004, NACE changed its nomenclature from "RP" to "SP" (Standard Practice). Therefore, RP0198 and SP0198 refer to the same document, but SP0198 is the current designation. Why is NACE SP0198 Critical for Industrial Facilities? Corrosion under insulation is responsible for up to 40-60% of piping maintenance costs in petrochemical, refining, and offshore industries. The hidden nature of CUI means that by the time it is visible (insulation removal), significant wall loss may have already occurred.
A: Yes. The title includes "...and Fireproofing Materials." It specifically addresses corrosion under fireproofing (CUF), which is a related but distinct mechanism. nace sp0198 pdf
