2、ional Standards Institute, Inc. AMERICAN NATIONAL STANDARD B11.102003 (R2015) i AMERICAN NATIONAL STANDARDS 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 B11 Standards,

3、 Inc. (the ANSI-accredited standards developing organization). American National 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 simpl

4、e majority, but not necessarily unanimity. Consensus requires that all views 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 publicatio

5、n. While B11 Standards, Inc. administers the process and establishes procedures to promote 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

6、 contained in its standards or guidelines. American National Standards are promulgated through 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

7、 procedures not conforming to the standards. However, users, distributors, regulatory bodies, 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

8、 will in no circumstances give an interpretation of an 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.

28、oreword (This foreword is not part of the requirements of American National Standard B11.10-2003) The primary objective of this standard is to eliminate or control hazards to personnel associated with metal sawing machines by establishing requirements for the construction, operation and maintenance

29、of these machines. To accomplish this objective, responsibilities have been assigned to the supplier (e.g., manufacturer, rebuilder, modifier, installer, integrator), the user, and personnel in the working environment. Metal sawing machines and associated equipment technologies are continuously evol

30、ving. 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 su

31、ch technologies. The words “safe“ and “safety“ are not absolutes. Safety begins with good design. While the goal of this standard is to eliminate injuries, it is recognized that risk factors cannot be practically reduced to zero in any human activity. This standard is not intended to replace good ju

32、dgment and personal responsibility. Operator skill, attitude, training, job monotony, fatigue and experience are safety factors that must be considered by the user. Inquiries with respect to the application or the substantive requirements of this standard and suggestions for its improvement are welc

33、omed, and should be sent to B11 Standards, Inc., POB 690905, Houston TX 77269, 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 approval date on the title

34、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 Subcommittee recommends that sup

35、pliers complete and implement design changes within 30 months of the approval of this standard. For existing or modified machines, users should confirm that the equipment / process has tolerable risk using generally recognized risk assessment methods. If the risk assessment shows that modification(s

36、) is necessary, refer to the requirements of this standard to implement protective measures for appropriate risk reduction. This standard was prepared by the B11.10 Subcommittee, processed and submitted for ANSI approval by the B11 Accredited Standards Committee on Safety Standards for Machine Tools

37、. Committee approval of this standard does not necessarily imply that all committee members voted for its approval. At the time this standard was approved as an American National Standard, the ANSI B11 Accredited Standards Committee was composed of the following member organizations: John W. Russell

41、fety gage refers to limiting device (e.g., backgage). As in all American National Standards, the term “SHALL” denotes a requirement that is to be strictly followed in order to conform with this standard; no deviation is permitted. The term “SHOULD” denotes a recommendation, a practice or condition a

42、mong several alternatives, or a preferred method or course of action. Similarly, the term “CAN” denotes a possibility, ability or capability, whether physical or casual, and the term “MAY” denotes a permissible course of action within the limits of the standard. Suggestions for improvement of this s

43、tandard will be welcome. They should be sent to B11 Standards, Inc., POB 690905, Houston TX 77269, USA - Attention: B11 Secretariat. AMERICAN NATIONAL STANDARD B11.102003 (R2015) vii Introduction The primary purpose of every machine tool is to process parts. This is accomplished by the machine impar

44、ting process energy onto the workpiece. It is during this interaction between the machine and the workpiece where inadvertent interference with, or accidental misdirection of the released process energy can potentially cause injury. Hazards exist that may result in injury during production, maintena

45、nce, commissioning and de-commissioning. The purpose of the ANSI B11 series machine tool safety standards is to devise and propose ways to minimize risks of the potential safety hazards. This can be accomplished either by an appropriate machine design, by restricting personnel or other individuals a

46、ccess to hazard areas, and by devising work procedures to minimize personnel exposure to hazardous situations. This is the essence of the ANSI B11 safety standards. The responsibility for the alleviation of these risks is divided between the equipment supplier, the equipment user and its operating p
