The document NACE RP0472 is an old standard that has been withdrawn and replaced. It is no longer considered "new," and you should not use it for current specifications or regulatory compliance.
Because the keyword includes “PDF new,” it is clear you want a portable, searchable, and legal digital copy. Here is the step-by-step method.
Searching for a new PDF is not about vanity—it is about legal compliance and technical accuracy. Older versions (e.g., 2002, 2005, 2015) contain withdrawn methods, obsolete coating references, and testing procedures that no longer meet industry best practices.
First, a critical nomenclature update. NACE International (now part of AMPP: The Association for Materials Protection and Performance) transitioned from “RP” (Recommended Practice) to “SP” (Standard Practice) in the early 2010s. Therefore, the current official designation is NACE SP0472-2020 (or the most recent revision).
Full Title: Methods and Materials to Prevent Corrosion Beneath Pipe Supports (CBPS)
The standard addresses a notoriously vulnerable area in industrial piping systems: the interface between the pipe and its support. Water, debris, and aggressive ions become trapped at these points, leading to accelerated corrosion known as Corrosion Under Pipe Supports (CUPS).
