​This Practice provides the procedures for Function Teams (FTs) creating, revising, and managing Piping Material Specification (PMS) Practices, Valve Description Practices (VDPs), Piping Material Specification Indexes, and related internal function team documents used to support these Practice work processes. These Practices are used by several of the Function Teams with some variation in the usage of the optional or recommended work process portions included in this Practice. The subject Practices of the Piping Function Team (PFT), the Pipeline Systems Function Team (PLFT) and the Hygienic Process Function Team (HPFT) are covered by this Practice.This Practice describes content and work process management procedures that include review and approval of Practice drafts, communications between PIP Office and PIP Function Teams, tracking, reporting, publishing, and archiving of Practice, except as covered by other ADG Practices.This Practice supplements and shall be used in conjunction with PIP ADG001, PIP ADG003, PIP ADG006, PIP ADG010 and various related Function Team decisions and guidelines.The structure and content of these Practices are defined herein to leverage best practices and provide consistency for end users in projects that may span piping systems including different design codes. This is also helpful for PIP Function team members participating on multiple teams and for the PIP staff. These definitions provide the basis for developing new Practices with continuity of work and consistency of content.
