Foreword The purpose of this publication is to assist NEMA Sections in the preparation of NEMA Standards Publica
24、tions (SP). Additionally, this guide will be used by the NEMA Communications Department in resolving non-technical questions and in preparing SPs for publication. The guide offers rules on content, NEMA practices, and style specifications for organization of the various parts of NEMA SPs. The guide
25、was designed to ensure that NEMA SPs are well organized and are consistent in style within itself and with other NEMA SPs. By following the guides rules when preparing standards, Section working groups and committees can help speed publication of their work. In 1990 the Codes and Standards Committee
26、 voted to provide an exception to the NEMA style by providing an option for those Sections that wish to use the ISO/IEC style in preparation for submittal to those bodies. In 1995 Codes and Standards adopted a new format for NEMA standards that reflects the evolution of opinion on how a SP should be
27、 presented. This new format, described in NS 1, is aligned with the presentation formats used by other standards producing organizations such as ISO, IEC, and ANSI while keeping elements necessary to the understanding of electrical manufacturing standards. NEMA typically develops standards that are
28、published with a NEMA designation, an ANSI designation, or both. NEMA also develops standards that are submitted to IEC or ISO for consideration. To facilitate the development of these standards, templates for NEMA, ANSI and IEC standards (NS 1.dot, ANSI.dot, IEC.dot, respectively) have been made av
29、ailable to NEMA Staff. Training in the use of these templates may be requested by contacting the Standards Editor. The Communications Department has worked closely with the Technical Services Department and with individual NEMA Sections in the drafting of this guide and acknowledges the need for per
30、iodic review and updating. Proposed or recommended revisions should be submitted to: Vice President, Communications Department National Electrical Manufacturers Association 1300 North 17th Street Rosslyn, Virginia 22209 NS 1-2005 Page 1 Copyright 2005 by the National Electrical Manufacturers Associa

45、rs Association. Section 2 NEMA STANDARDIZATION 2.1 SECTION OR GROUP RESPONSIBILITY The NEMA Section sponsoring a proposed NEMA SP must provide for Codes and Standards Committee approval a complete draft that meets the requirements of this guide for mandatory content, organization, style, and legibil
46、ity. Concurrent with submittal for Codes and Standards review, the draft hard copy and Word file shall be submitted to the Communications Department. The Communications Department shall edit and format the SP according to the requirements of this document. The sponsoring Section shall have final rev
47、iew before publication. When a proposed SP is balloted for approval by a Section, it shall contain all the elements necessary to be published. The draft shall be legible in all respects. This will facilitate more prompt publication. All drawings, graphs, equations, and tables shall be included. 2.2
