3、onal 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 National Standards are developed throu

4、gh 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 views and objections be considered, and

5、 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 promote fairness in the development of cons

6、ensus, 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 e

7、xistence 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 other

8、s 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. Moreover, no person shall have the right or

30、 ANNEX G BANDING AND UNBANDING OF COILS AND CONSTRAINT OF PARTIAL COILS57 i FOREWORD (This Foreword is informative and not part of the requirements of American National Standard B11.18-2006.) The primary objective of this standard is to eliminate, control or reduce hazards to individuals associated

31、with metal, sheet, strip or plate processing systems by establishing requirements for the design, construction, installation, commissioning, operation, maintenance and decommissioning of these machines. To accomplish this objective, responsibilities have been assigned to the supplier (e.g., manufact

32、urer, 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, control, or reduce hazards, this standard recognizes

33、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 factors that should be considered by the user. The original

34、 B11.18 Standard was approved in 1985 and revised and approved again in 1992. B11.18 was then reaffirmed in 1997. This current standard began revision in 2004, and with the approval of the B11 Accredited Standards Committee, includes and incorporates the safety requirements of coil slitting machines

35、 the subject matter of ANSI B11.141996. B11.14 will be formally withdrawn as an American National Standard upon ANSI approval of this revised standard as an American National Standard. Technology for metal/sheet/strip/plate processing systems from coiled or non-coiled configurations is continuously

36、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 area of this standard, in no way infers acceptance or rejection o

37、f 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 committee members voted for its approval. At the time this documen

38、t 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 and suggestions for its improvement are welcomed and are to be s

39、ent to AMT - The Association For Manufacturing Technology, 7901 Westpark Drive, McLean, Virginia 22102-4206. 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 t

40、he approval date on the title page of this document is necessary for suppliers and users to develop new designs, or modify existing designs or manufacturing processes in order to incorporate the new or revised requirements of this standard into their product development or production system. This Su

41、bcommittee recommends that suppliers complete and implement design changes for new machines within 30 months of the approval of this standard. For existing or modified machines, this Subcommittee recommends that users should confirm that the equipment / process has tolerable risk using generally rec

42、ognized risk assessment methods within 30 months of the approval date of this standard. If the risk assessment shows that modification(s) is necessary, refer to the requirements of this standard to implement protective measures for appropriate risk reduction. ii B11 Accredited Standards Committee RO

46、esa F. Stillman National Institute for Occupational Safety and Health Richard S. Current, PE James R. Harris, MS, PE Occupational Safety no deviation is permitted. The term “SHOULD” denotes a recommendation, a practice or condition among several alternatives, or a preferred method or course of actio

47、n. Similarly, the term “CAN” denotes a possibility or capability, whether physical or causal, and the term “MAY” denotes a permissible course of action within the limits of the standard. B11 conventions: Operating rules (safe practices) are not included in either column of this standard unless they

48、are of such nature as to be vital safety requirements, equal in weight to other requirements, or guides to assist in conformance to the standard. The B11 series of standards do not use the term “and/or” but instead, the term “OR” is used as an inclusive disjunction, meaning one or the other or both.

49、 A distinction between the terms “individual” and “personnel” is drawn. Individual includes personnel (employees, subcontractors, consultants, or other contract workers under the indirect control of the supplier or user) but also encompasses persons who are not under the direct or indirect control of the supplier or user (e.g., visitors, vendors, etc.). Gauge refers to a measuring or testing instrument; gage refers to a limiting device (e.g., backgage). Suggestions for improvement of this standard will be welcome. They s
