12、NAL STANDARD Approval of an American National Standard requires verification by The American National Standards Institute, Inc. (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 c

13、onsensus 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 ma

14、jority, 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, fr

15、om 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, Inc., does not develop standards and will in no ci

16、rcumstances 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, Inc. Requests for interpretations should be addressed to t

31、ndard methods to be used in testing dry cells. Their recommendations were followed five years later when the National Bureau of Standards (currently the National Institute of Standards and Testing) prepared specifications that included cell sizes, arrangement of cells within batteries, service tests

32、, 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. This committee, C18, representing battery users, manufacturers, and government agencies, has re

33、mained active since that time. Committee C18 prepared ANSI Standard C18.1M, Part 2, upon which this document is originally based under the sponsorship of the National Electrical Manufacturers Association (NEMA). ANSI Standard C18.1M, Part 2 was created in parallel with the International Electrotechn

34、ical Commission (IEC) project to develop a product safety standard for primary batteries with aqueous electrolyte (IEC Publication 60086-5). This revision was undertaken to update the safety tests and content in ANSI Standard C18.1M, Part 2 and to keep them current with the best possible practices.

35、Suggestions for the improvement of this standard are welcome. They should be sent to the National Electrical Manufacturers Association, 1300 N. 17th Street, Suite 900, Rosslyn, VA 22209, Attention: Secretary ANSI ASC C18. This standard was processed and approved for submittal to ANSI by the Accredit

36、ed Standards Committee C18 on Portable Cells and Batteries. Committee approval of the standard does not necessarily imply that all committee members voted for its approval. At the time it approved this standard, the C18 committee had the following members: Steven Wicelinski, Chairperson Marcus Booli

This standard

42、 defines performance requirements for primary batteries with aqueous electrolyte to ensure their safe operation under normal use and reasonably foreseeable misuse. Safety is a balance between freedom from risk of harm and other demands to be met by the product. There can be no absolute safety. Even

43、at the highest level of safety, the product can only be relatively safe. In this respect, decision-making is based on risk evaluation and safety judgment. As safety will pose different problems, it is impossible to provide a set of precise provisions and recommendations that will apply in every case

44、. This may be particularly true for button type batteries. However, this standard, when followed on a judicious “use when applicable” basis, will provide reasonably consistent standards for safety. 2 Scope This American National Standard specifies tests and requirements for portable primary batterie

45、s with aqueous electrolyte and zinc anode (non-lithium) to ensure their safe operation under normal use and reasonably foreseeable misuse. For reference, the chemical systems standardized in ANSI C18.1M, Part 1 are: a. Carbon Zinc (Leclanch and Zinc Chloride types); b. Alkaline Manganese Dioxide; c.

46、 Silver Oxide; d. Zinc air; e. Nickel Oxy-Hydroxide. 3 Normative References The following standards contain provisions which, through reference in this text, constitute provisions of this American National Standard. At the time of publication, the editions indicated were valid. All standards are sub

47、ject to revision, and parties to agreements based on this American National Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.
