    4、National Standard, the ANSI Board of Standards Review confirms that the requirements for due process, consensus, balance and openness have been met by B11 Standards, Inc., (the ANSI-accredited standards developing organization). American National Standards are developed through a consensus process.

    5、Consensus is established when 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

    6、 be made toward resolution. This process brings together volunteers and/or seeks out the views of persons who have an interest in the topic covered by this publication. While B11 Standards, Inc., administers the process and establishes procedures to promote fairness in the development of consensus,

    7、it does not write the document and it does not independently test, evaluate or verify the accuracy or completeness of any information or the soundness of any judgments contained in its standards or guidelines. American National Standards are promulgated through ANSI for voluntary use; their existenc

    8、e does not in any respect preclude anyone, whether they have approved the standards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. However, users, distributors, regulatory bodies, certification agencies and others conce

    9、rned may apply American National Standards as mandatory requirements in commerce and industry. The American National Standards institute does not develop standards and will in no circumstances give an interpretation of an American National Standard. Moreover, no person shall have the right or author

    10、ity 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 Secretariat (B11 Standards, Inc.,). B11 Standards, Inc., MAKES NO WARRANTY, EITHER EXPRESSED OR IMPLIED AS TO THE FITNESS

    11、OF MERCHANTABILITY OR ACCURACY OF THE INFORMATION CONTAINED WITHIN THIS STANDARD, AND DISCLAIMS AND MAKES NO WARRANTY THAT THE INFORMATION IN THIS DOCUMENT WILL FULFILL ANY OF YOUR PARTICULAR PURPOSES OR NEEDS.

    12、es of any nature whatsoever, whether special, indirect, consequential or compensatory, directly or indirectly resulting from the publication, use of, application or reliance on this document. B11 Standards, Inc., does not undertake to guarantee the performance of any individual supplier or sellers p

    13、roducts or services by virtue of this standard or guide, nor does it take any position with respect to the validity of any patent rights asserted in connection with the items which are mentioned in or are the subject of this document, and B11 Standards, Inc., disclaims liability for the infringement

    14、 of any patent resulting from the use of or reliance on this document. Users of this document are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, is entirely their own responsibility.

The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard. You may contact the Sec

    19、retariat for current status information on this, or other B11 standards.

The primary objective

    41、 of this standard is to eliminate, control or reduce hazards to individuals associated with grinding machines by establishing requirements for the design, construction, installation, commissioning, operation, maintenance and decommissioning of these machines. To accomplish this objective, responsibi

    42、lities have been assigned to the supplier (e.g., supplier, modifier, distributor, rebuilder and integrator), the user, and individuals in the working environment. The words “safe“ and “safety“ are not absolutes. An element of safety is attitude. While the objective of this standard is to eliminate,

    43、control, or reduce hazards, this standard recognizes that hazards cannot be practically reduced to zero in any human activity. This standard is not intended to replace good judgment, proper training, and personal responsibility. Operator skill, job monotony, fatigue, and experience are safety factor

    44、s that should be considered by the user. The original B11.9 Standard was approved in 1975, and has simply been reaffirmed periodically since then. This current standard began revision in 2005, closely collaborating with the ANSI B7.1 Committee. A memorandum of understanding was reached between the t

    45、wo separate standards development committees that going forward, this B11.9 standard would address the safety requirements of the grinding machine only, and B7.1 would address the safety requirements of the abrasive product only (with the largest single area of overlap being the flange, mostly addre

    46、ssed in B7.1). Technology for grinding machines is continuously evolving. This standard reflects the most commonly used and time-tested state of the art at the time of its approval. The inclusion or omission of language relative to any evolving technology, either in the requirements or explanatory a

    47、rea of this standard, in no way infers acceptance or rejection of such technologies. This standard was processed and submitted for ANSI approval by the B11 Accredited Standards Committee on safety standards for machine tools. Committee approval of this standard does not necessarily imply that all co

    48、mmittee members voted for its approval. At the time this document was approved as an American National Standard, the ANSI B11 Accredited Standards Committee was composed of the following member organizations: Inquiries with respect to the application of the substantive requirements of this standard

    49、and suggestions for its improvement are welcomed and are to be sent to B11 Standards, Inc., 42293 Young Lane, Leesburg, Virginia 20176. Attention: B11 Secretariat. Effective Date The following is informative guidance only, and not a normative part of this standard. This Subcommittee recognizes that some period of time after the approv
