Laboratory Measurement of,Aerodynamic Noise Generated,by Control Valves,Approved 31 August 1997,ISA–75.07–1997,Formerly ISA–S75.07–1997,STANDARD,ISA The Instrumentation,Systems, and,Automation Society,–,TM,ISA-75.07-1997, Laboratory Measurement of Aerodynamic Noise Generated by Control Valves,ISBN: 1-55617-653-8,Copyright . 1997 by the Instrument Society of America. All rights reserved. Printed in the,United States of America. No part of this publication may be reproduced, stored in a retrieval,system, or transmitted, in any form or by any means (electronic, mechanical, photocopying,recording, or otherwise), without the prior written permission of the Publisher.,ISA,67 Alexander Drive,P. O. Box 12277,Research Triangle Park, North Carolina 27709,ISA-S75.07-1997 3,Preface,This preface, as well as all footnotes and annexes, is included for information purposes only and,is not part of ISA-75.07-1997.,This Standard has been prepared as part of the service of ISA, the international society for,measurement and control, 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 addressed to the,Secretary, Standards and Practices Board, ISA; 67 Alexander Drive; P.O. Box 12277; Research,Triangle Park, NC 27709; Telephone (919) 990-9227; Fax (919) 549-8288; Internet:,standards@isa.org.,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, recommended practices, and technical reports. The,Department is further aware of the 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 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 & 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 the 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,endorsement by the employer of that individual, of ISA, or of any of the standards that ISA,develops.,Caution,The use of this standard may involve hazardous materials, operations, or,equipment. The standard cannot anticipate all possible applications or,address all possible safety issues associated with use in hazardous,conditions. The user of this standard must exercise sound professional,judgment concerning its use and applicability under the user’s particular,circumstances. The user must also consider the applicability of any,governmental regulatory limitations and established safety and health,practices before implementing this standard.,Additionally, implementation of the standard may require use of,techniques, processes, or materials covered by patent rights. ISA takes,no position on the existence or validity of any patent rights which may,be involved in implementing the standard. ISA will not be responsible for,identifying all patents that may require a license before implementation,of the standard or for investigating the validity or scope of any patents,brought to its attention. The user should carefully investigate relevant,patents before using the standard for the user’s intended application.,4 ISA-S75.07-1997,The following people served as members of ISA Subcommittee SP75.07:,NAME COMPANY,C.
