PIC001 Criteria - Purpose and Use of Process Industry Practices

Oct 28, 2026

Upload by Finn

Process Industry Practices (PIP) provides a harmonized practice framework intended to reduce administrative, application, and engineering costs for process industry facilities. It defines purpose, scope, and how Piping and Instrumentation Diagrams (P&IDs) should be documented, including format and content expectations. The practice emphasizes compliance with applicable laws and regulations such as OSHA, allows trade-name substitutions when equivalent, and notes revision cadence and referenced standards used as integral requirements.

By harmonizing these technical requirements into a single set of Practices, administrative, application, and engineering costs to both the purchaser and the manufacturer should be reduced. While this Practice is expected to incorporate the majority of requirements of most users, individual applications may involve requirements that will be appended to and take precedence over this Practice. Determinations concerning fitness for purpose and particular matters or application of the Practice to particular project or engineering situations should not be made solely on information contained in these materials. The use of trade names from time to time should not be viewed as an expression of preference but rather recognized as normal usage in the trade. Other brands having the same specifications are equally correct and may be substituted for those named. All Practices or guidelines are intended to be consistent with applicable laws and regulations including OSHA requirements. To the extent these Practices or guidelines should conflict with OSHA or other applicable laws or regulations, such laws or regulations must be followed. Consult an appropriate professional before applying or acting on any material contained in or suggested by the Practice. This Practice is subject to revision at any time by the responsible Function Team and will be reviewed every 5 years. This Practice will be revised, reaffirmed, or withdrawn. Information on whether this Practice has been revised may be found at [http://www.pipdocs.org](http://www.pipdocs.org). © Process Industry Practices (PIP), Construction Industry Institute, The University of Texas at Austin, 3208 Red River Street, Suite 300, Austin, Texas 78705.
