4、DARDS By approving this American National Standard, the ANSI Board of Standards Review confirms that the requirements for due process, consensus, balance and openness have been met by AMT The Association For Manufacturing Technology (the ANSI-accredited standards developing organization). American N
5、ational Standards are developed through a consensus process. 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 vi
6、ews and objections be considered, and that a concerted effort 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 AMT administers the process and establishes procedures to promot
7、e fairness in the development of consensus, 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 th
8、rough ANSI for voluntary use; their existence 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 bod
9、ies, certification agencies and others concerned 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. Moreov
10、er, 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 should be addressed to the Secretariat (AMT). AMT MAKES NO WARRANTY, EITHER EXPRESSED OR IMPLIED AS TO TH
11、E FITNESS 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.

13、irtue 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 AMT disclaims liability for the infringement of any patent resulting from the use of

16、ional in determining the exercise of reasonable care in any given circumstances. AMT has no power, nor does it undertake to police or enforce conformance to the requirements of this document. AMT does not certify, test or inspect products, designs, or installations for safety or health purposes. Any
17、 certification or other statement of conformance to any health or safety-related information in this document shall not be attributable to AMT and is solely the responsibility of the certifier or maker of the statement. NOTICE: This American National Standard may be revised or withdrawn at any time.
18、 The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard.

32、y of the finished work; the skill of operators; the length of run; and the method of feeding, including part and scrap removal. Because of these varying factors in the operations and in the workplace, a wide variety of pointofoperation safeguarding methods (guards and protective devices) has been co
33、vered in this standard. Pointofoperation safeguarding, the single most important factor in the elimination of injuries from presses, can only be determined by the user. A production system consists of the press as one component, dies (tooling) as another component, feeding methods (including part or
34、 scrap removal) as a third component, and pointofoperation safeguarding as the fourth component. The vital fourth component can be evaluated for effectiveness only after the first three components and operator involvements are known. Since this information is known only by the user, the responsibili
35、ty for conformance with clause 8 has been assigned accordingly. The assignment of responsibility of the user for proper pointofoperation safeguarding has existed since the first B11.1 standard, approved in 1922. Mechanical power presses and associated equipment technologies are continuously evolving
36、. 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 area of this standard, in no way infers acceptance or rejection of such t
37、echnologies. HISTORY The project on Safety Standard for Power Presses, B11, was initiated under the procedures of the American Engineering Standards Committee (which became the American Standards Association, the United States of America Standards Institute, and in 1969 the American National Standar
38、ds Institute), with the National Safety Council as sponsor. The first standard, bearing the title Safety Code for Power Presses and Foot and Hand Presses, was developed by Sectional Committee B11 and was approved on November 13, 1922. Only two purposes of that “code“ were listed. The first and prima
39、ry use was for state industrial commissions in developing their workplace codes. The second use was as an operating guide for users operating press production systems. Revisions of the standard were issued on November 11, 1926; October 22, 1937; January 12, 1948; January 19, 1960; February 17, 1971;
40、 January 22, 1982; April 4, 1988; and November 6, 2001. The philosophy underlying the 1971 standard was handsoutofdie operation (HOOD). After the adoption of the 1971 standard by ANSI and its reference by OSHA regulations, many users documented an absolute inability to meet the handsoutofdie objecti
41、ve. Accordingly, in 1974 OSHA modified the HOOD requirement, and subsequent versions of the ANSI B11.1 standard incorporate that modification. However, HOOD should be considered in the application of the press production system, with appropriate Copyright B11 Standards Inc. (Formerly AMT) Provided b

43、power presses. In this 2009 edition of the standard, the B11.1 Subcommittee reviewed the B11.1 2001 standard to incorporate current mechanical power press safety practice, and to increase explanatory material related to the standard. New areas that have been added include requirements for risk asses
44、sment and risk reduction for increasingly complex automatic press production systems that may include tandem and transfer presses with use of perimeter safeguarding. In addition, new pressroom technology including direct drive servo presses has been incorporated. The current edition also integrates
45、NFPA 79 requirements directly within the standard, including two hand control and stop function requirements, moving parts (other than point-of-operation) and safeguarding supplier responsibilities. Finally, the current edition of ANSI B11.1 provided new requirements for slide locks, moving bolsters
46、 and scrap chutes. Subsequent to beginning the revision of B11.1, the ANSI B11 Accredited Standards Committee (ASC) authorized creation of an overarching (“A-level”) standard dealing with general safety requirements for the entire series of machines. ANSI B11 was approved in August 2008. Since B11.1
47、 was already well into its revision at that point, the B11 ASC agreed to allow this current (2009) version of the ANSI B11.1 standard to proceed absent integration with the ANSI B11 “A-level” standard. Effective Date The following information on effective dates is informative guidance only, and not
48、a normative part of this standard. The subcommittee recognizes that some period of time after the approval date on the title page of this document is necessary for suppliers and users to develop new designs, and/or modify existing designs or manufacturing processes in order to incorporate the new an
49、d/or revised requirements of this standard into their product development or production system. The subcommittee recommends that suppliers complete and implement design changes for new machine tools and machine tool systems within 30 months of the approval of this standard. The subcommittee recommends th
