The American Society of Mechanical Engineers' (ASME) RTP-11 standard is a document that was written for the design, fabrication and stamping of reinforced therrnoset plastic corrosion equipment. Industry has recognized this document as a useful reference for the procurement of fiberglass reinforced plastic (FRP) equipment. However, the
misconception that by specifying "to be built in accordance with" will automatically yield a better product has caused some users to be
disappointed after they take delivery of their equipment. This paper will attempt to clarify some of the major differences in "built in accordance with" vs. "designed, fabricated and stamped in accordance with" the ASME RTP-1 Document.
