SCOPE AND PURPOSE  \n1.1 This standard presents both symbols and diagramming format for use in representing measuring, controlling and computing systems.  \n1.2 The purpose of this standard is to establish uniformity of symbols and practices in diagramming such systems in their basic functional form, exclusive of their operating media or specific equipment detail.  \n1.3 The flexibility of the symbols and format, however, provides for development of diagrams that display easily understandable equipment relationships for either analog or digital systems.  \n2. INTRODUCTION  \n2.1 To clarify the type of diagram with which this standard is concerned it is assumed that in designing a complex measuring, control or computational system the following types of diagrams will be required:  \na) functional diagrams  \nb) detailed schematic diagrams  \nc) interconnection diagrams  \nd) ISA Process & Instrumentation (P&I) Diagrams  \nThis standard is concerned only with the functional diagram normally prepared in the early stages of system conception from the mechanical or process flow sheet. It normally is revised and kept current with concept as system design progresses through the various stages of negotiation, quotation, contract award, reduction to final equipment, syst","cbCaikZoAD3MYB7j","https://ap.wps.com/l/cbCaikZoAD3MYB7j","pdf",656351,29,"English","# 1.
