26、ge v 2014 National Electrical Manufacturers Association FOREWORD In 1912, a committee of the American Electrochemical Society recommended standard methods to be used in testing dry cells. Their recommendations were followed five years later when the National Bureau of Standards prepared specificatio

27、ns that included cell sizes, arrangement of cells within batteries, service tests, and required performance. The need for continued revision to the specification led to the authorization by the American Engineering Standards committee of a permanent sectional committee on dry cells, now portable cel

28、ls. This Committee, C18, representing battery users, manufacturers, and government agencies, has remained active since that time. This standard is a revision of ANSI C18.2M, Part 1-2007American National Standard for Portable Rechargeable Cells and Batteries General and Specifications. This current r

29、evision seeks to improve upon previous editions of this standard by adding consumer product acceptance procedures such as clarification of rated capacity, cycle life, and application charge capacity. Harmonization with the other ANSI C18 Standards was implemented where applicable. The basic philosop

30、hical approach used in developing this standard was that of setting forth uniform test procedures that permit manufacturers self-declaration with regard to the performance levels of their products, or, in some cases, establishing minimum acceptable performance levels. In April 1996, the then ANSI Ac

31、credited Standards Committee C18 on Specifications for Dry Cells and Batteries established a new general format for the publication of its standards, dividing this standard into two parts. Part 1 of this American National Standard for Portable Rechargeable Cells and Batteries contains two basic sect

32、ions. The first section has general requirements and information, such as the scope, applicable definitions, general descriptions of battery dimensions, terminal requirements, marking requirements, general design conditions, test requirements, etc. Section 2 of Part 1 is comprised of specification s

33、heets for various types of cells and batteries. Part 2 of the standard, a separate document, contains safety requirements. Suggestions for the improvement of this standard will be welcome. They should be sent to: Senior Technical Director, Operations National Electrical Manufacturers Association 130

34、0 North 17th Street, Suite 900 Rosslyn, VA 22209. Attention: Secretary ANSI ASC C18 This standard was processed and approved for submittal to ANSI by the American National Standards Committee C18 on Portable Cells and Batteries. Committee approval of this standard does not necessarily imply that all

35、 committee members voted for its approval. When Committee C18 approved this standard, it had the following members: Michael H. Babiak, Chairperson Steven Wicelinski, Vice Chairperson Andrei Moldoveanu, Secretary Organization Represented: Name of Representative: BAE Systems Andrew Markow Bureau Verit

Keel Kelly (Alternate) C18.2M, Part 1-2013 Page vi 2014 National Electrical Manufacturers Association DeJager b) To minimize proliferation of cell and battery types; c) To define standard performance tests and provide guidance for their assessment; and,

37、 d) To provide guidance to consumers, manufacturers, designers, and other end users. This is achieved by specifying designations, dimensions, polarity, terminals, markings, test conditions, and procedures. 1.2 Normative references The following standards contain provisions that, through reference in

38、 this text, constitute provisions of this American National Standard. At the time of publication, the edition indicated was valid. All standards are subject to revision, and parties to agreements based on this American National Standard are encouraged to investigate the possibility of applying the m

39、ost recent edition of the standard indicated below.
