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
9、 benefits to USA users 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 introduce SI-acceptable metric units in all new and revised standards, re
10、commended practices, and technical reports to the greatest extent possible. Standard for Use of the International System of Units (SI): The Modern Metric System, published by the American Society for Testing it is a dimension for only the valve itself. 11 ANSI/ISA-75.08.09-2016 Copyright 2016 ISA.

Face-to-face dimensions to start this standard were obtained from Scientific Apparatus Makers Association (SAMA), Proposed Standard PMC 23.3e
12、1975, “Face-to-Face Dimensions of Flangeless Control Valves.” Dimensions for metrically sized valves are nominal conversions that are conventionally used in the Manufacturers Standardization Society (MSS) of the Valve and Fitting Industry (MSS-SP86-1997), International Standards Organization (ISO),
13、 and International Electrotechnical Commission (IEC). This page intentionally left blank. Developing and promulgating sound consensus standards, recommended practices, and technical reports is one of ISAs primary goals. To achieve this goal the Standards and Practices Department relies on the techni
14、cal expertise and efforts of volunteer committee members, chairmen and reviewers. ISA is an American National Standards Institute (ANSI) accredited organization. ISA administers United States Technical Advisory Groups (USTAGs) and provides secretariat support for International Electrotechnical Commi
15、ssion (IEC) and International Organization for Standardization (ISO) committees that develop process measurement and control standards.
