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 use of American National Standards is completely voluntary; their existence,does not in any respect preclude anyone, whether he has approved the standards or,not, from manufacturing, marketing, purchasing, or using products, processes, or,procedures not conforming to the standards.,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 shall be addressed to the secretariat or sponsor whose,name appears on the title page of this standard.,CAUTION NOTICE: This American National Standard may be revised or withdrawn,at any time.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 to reaffirm, revise, or withdraw this standard no later than five,years from the date of approval. Purchasers of American National Standards may,receive current information on all standards by calling or writing the American,National Standards Institute.,Published by,National Electrical Manufacturers Association,1300 N. 17th Street, Rosslyn, Virginia 22209,Copyright O 2000 National Electrical Manufacturers Association,Ali 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,Copyright National Electrical Manufacturers Association,Provided by IHS under license with NEMA,No reproduction or networking permitted without license from IHS Not for Resale,--```-`-`,,`,,`,`,,`---,_ _ _ _ _ ~ ~ ~ _ _ _ _~~~ _ ~ ~ ~~ ~ ~ _ _ _ _ _ ~ ~,STD-NEMA C29-2-ENGL 3992 M 6430247 0524336 634 D,ANSI C29.2-1992 (Rl999),Contents,Page,Foreword III,1 Scope 1,2 Normative references . 1,3 Definitions 1,4 General . 2,5 Material . 2,5.1 Insulator shells . 2,5.2 Shell surface . 2,5.3 Metal parts . 3,5.4 Cotter keys 3,5.4.1 Material . 3,5.4.2 Ball-and-socket insulators . 3,5.4.3 Clevis insulators . 3,Dimensions and characteristics . 3,Sampling, inspection, and tests . 4,8.1 General 4,8.2 Design tests .. 4,8.2.1 Low-frequency dry flashover test 4,8.2.2 Low-frequency wet flashover test .. 4,8.2.3 Critical impulse flashover tests-positive and negative .. 4,8.2.4 Radio-influence voltage test . 4,8.2.5 Thermal-mechanical load cycle test . 4,8.2.6 Thermal shock test 5,8.2.7 Residual-strength test .. 5,8.2.8 Impact test 5,8.2.9 Cotter key test .. 6,8.2.1 O Cement expansion . 6,8.3 Quality conformance tests . .. 6,8.3.1 Visual and dimensional tests 6,8.3.2 Porosity test . 6,8.3.3 Galvanizing test .. 6,8.3.4 Combined mechanical and electrical-strength tests 7,8.3.5 Puncture tests . 7,8.4 Routine tests 8,8.4.1 Cold-to-hot thermal shock test 8,8.4.2 Hot-to-cold thermal shock test 8,8.4.3 Tension proof test . 8,8.4.4 Flashover test .. 8,Table 4 - Dimensions and characteristics of clevis transmission insulators 11,(ANSI classes 52-4, 52-6, 52-10, 52-12) . 11,Figure 3 - Clevis suspension insulator c……
