The Truss Plate Institute establishes methods of design, construction and testing for metal plate connected wood trusses in accordance with the American National Standards Institute's accredited consensus procedures for the coordination and development of American National Standards.
TPI was granted standard-developing accreditation status by the American National Standards Institute (ANSI) under the "accredited organization method", one of three methods accepted by ANSI to determine the existence of consensus on American National Standards.
TPI's written procedures, "Project Committee Method to Achieve Consensus" (PCMAC), as approved by ANSI, ensure that TPI standards have achieved general recognition, agreement, and acceptance for use as a national voluntary standard. [View PCMAC]
