Part 227 of ISO 10303, 'Plant Spatial Configuration', specifies an application protocol (AP) for the exchange of spatial configuration information of process plants. This include shape characteristics, spatial arrangement characteristics, and design and fabrication information for piping system components, and functional and stream information for piping and HVAC (heating, ventilating, and air conditioning) systems. Also included are shape and spatial arrangement characteristics of other related plant systems that impact the design and layout of piping systems. This document specifies the scope and information requirements for AP 227 and provides the Application Activity Model (AIM) and Application Reference Model (ARM) for the AP. The document follows the format and clause numbering scheme prescribed for this type of International Organization for Standardization (ISO) standard. The clauses and annexes contained in this document are those required by ISO for Group 1 qualification. Additional clauses and annexes will be added to the AP during the completion of the standard.
