ANSI C18.3M, Part 2-2003 i AMERICAN NATIONAL STANDARD Approval of an American Nation
12、al Standard requires verification by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by direct
13、ly 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 use of American National Standards is co
14、mpletely voluntary; their existence does not in any respect preclude anyone, whether he has approved the standard 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
15、 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 s
16、hould 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 Caution Notice: This American National Standard may be revised or withdrawn at any time.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, revis
17、e, 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.

25、SI C18.3M, Part 2-2003 v Foreword (This Foreword is not part of American National Standard C18.3M, Part 2-2003.) 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 Na
26、tional Bureau of Standards prepared specifications 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
27、sectional committee on dry cells, now portable cells. This Committee, C18, representing battery users, manufacturers, and government agencies, has remained active since that time. In April 1996, the then ANSI Accredited Standards Committee C18 on Specifications for Dry Cells and Batteries establishe
28、d a new general format for the publication of its standards, dividing the standard into two parts. Part 1 of this American National Standard for Portable Lithium Primary Cells and Batteries contains two basic sections. The first section has general requirements and information, such as the scope, ap
29、plicable definitions, general descriptions of battery dimensions, terminal requirements, marking requirements, general design conditions, test conditions, etc. Section 2 of Part 1 is comprised of specification sheets for various types of cells and batteries. This Part 2 of the standard, a separate d
30、ocument, contains safety requirements. The ANSI Committee C18 on Portable Cells and Batteries completed what is in effect the first edition of this specification on safety requirements in 1999 under the sponsorship of the National Electrical Manufacturers Association (NEMA). The purpose of the first edition was to harmonize with the International Electrotechnical Commission (IEC) Publication 60086-4: Product Safety Standard for Primary Lithium Batteries.
