ANSI_ANSLG C78.42-2007,Revision of ANSI C78.42-2004,American National Standard,Approved: December 19, 2007 Secretariat: ANSLG,for electric lamps:,High-Pressure Sodium Lamps,Copyright . 2007 by American National Standard Lighting Group,Page 1 of 86,ANSI_ANSLG C78.42-2007,Revision of ANSI C78.42-2004,Copyright . 2007 by American National Standard Lighting Group,Page 2 of 86,American,National,Standard,Approval of an American National Standard requires verification,by ANSI that the requirements for due process, consensus, and,other criteria for approval have been met by the standards,developer. An American National Standard implies a consensus,of those substantially concerned with its scope and provisions.,Consensus is established when, in the judgment of the ANSI,Board of Standards Review, substantial agreement has been,reached by directly and materially affected interests. Substantial,agreement means much more than a simple majority, but not,necessarily unanimity. Consensus requires that all views and,objections be considered, and that a concerted effort be made,toward their resolution. The existence of an American National,Standard does not in any respect preclude anyone, whether s/he,has approved the standard or not, from manufacturing,marketing, purchasing, or using products, processes, or,procedures not conforming to the standards. It is intended as a,guide to aid the manufacturer, the consumer, and the general,public.,The American National Standards Institute does not develop,standards and will in no circumstances give an interpretation of,any American National Standard. Moreover, no person shall,have the right or authority to issue an interpretation of an,American National Standard in the name of the American,National Standards Institute. Requests for interpretations should,be addressed to the Committee Secretariat referred to on the title,page.,CAUTION NOTICE: This American National Standard may be,revised or withdrawn at any time. The procedures of the,American National Standards Institute require that action be,taken periodically to reaffirm, revise, or withdraw this standard.,Purchasers of American National Standards may receive current,information on all standards by calling or writing the American,National Standards Institute.,Copyright .2007 by American National Standard Lighting Group,All rights reserved.,No part of this publication may be reproduced in any form,in an electronic retrieval system or otherwise, without,prior written permission of the publisher.,Printed in the United States of America,ANSI_ANSLG C78.42-2007,Revision of ANSI C78.42-2004,Copyright . 2007 by American National Standard Lighting Group,Page 3 of 86,Foreword (This foreword is not part of American National Standard C78.42-2007),Suggestions for improvement of this standard should be submitted to the Secretariat,C78, American National Standard Lighting Group, 1300 North 17th Street, Suite 1752,Rosslyn, VA 22209.,This standard was processed and approved by the Accredited Standards Committee on,Electric Lamps, C78, and its Working Group C78 WG 04. Working Group approval of,the standard does not necessarily imply that all working group members voted for that,approval.,The following revision has been made to this document for section 2.1 of the 70-watt,S62 lamp and section 2.1 of the 100-watt, S54 lamp:,2.1 Starting voltage requirements (conditions of 6.1 (Part I) apply),Minimum rms open circuit voltage, lag circuit ballast.110 V,Minimum rms open circuit voltage, lead circuit ballast,(Note: This value may be reduced to a minimum of 95Vrms if the peak voltage,is increased 2% for every 1% reduction in rms value) ..110V,Pulse height..2500 - 4000 V,Pulse width, min 1 μs at 2250 V,Amendment / Change CDV RV,Revision CDV 78_(4)_4252 RV 78_(4)_4253,Dennis Holt, Chair, C78,Matt Clark, Technical Coordinator,Randolph N.
