Preface
This preface, as well as all footnotes and annexes, is included for information purpos and is not part of ANSI/ISA-RP12.06.01-2003.
This document has been prepared as part of the rvice of ISA⎯the Instrumentation, Systems, and Automation Society⎯toward a goal of uniformity in the field of instrumentation. To be of real value, this document should not be static but should be subject to periodic review. Toward this end, the Society welcomes all comments and criticisms and asks that they be addresd to the Secretary, Standards and Practices Board; ISA; 67 Alexander Drive; P. O. Box 12277; Rearch Triangle Park, NC 27709; Telephone (919) 549-8411; Fax (919) 549-8288; E-mail: standards@isa.
The ISA Standards and Practices Department is aware of the growing need for attention to the metric system of units in general, and the International System of Units (SI) in particular, in the preparation of instrumentation standards. The Department is further aware of the benefits to USA urs of ISA
standards of incorporating suitable references to the SI (and the metric system) in their business and professional dealings with other countries. Toward this end, this Department will endeavor to introdu
ce
SI-acceptable metric units in all new and revid standards, recommended practices, and technical
reports to the greatest extent possible. Standard for U of the International System of Units (SI): The Modern Metric System, published by the American Society for Testing & Materials as IEEE/ASTM SI 10-97, and future revisions, will be the reference guide for definitions, symbols, abbreviations, and
conversion factors.
It is the policy of ISA to encourage and welcome the participation of all concerned individuals and
interests in the development of ISA standards, recommended practices, and technical reports. Participation in the ISA standards-making process by an individual in no way constitutes endorment by
the employer of that individual, of ISA, or of any of the standards, recommended practices, and technical reports that ISA develops.
