(the ANSI-accredited
3、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 simple majority, but not necessa
4、rily 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 publication. While B11 Standards, Inc

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 procedures not conforming
7、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.

28、ystems by establishing requirements for the construction, operation and maintenance of these machines. To accomplish this objective, responsibilities have been assigned to the supplier (e.g., manufacturer, rebuilder, reconstructor, installer, integrator), the user, and personnel in the working envir
29、onment. 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 judgment an
30、d personal responsibility. Operator skill, attitude, training, job monotony, fatigue and experience are safety factors that must be considered by the user. 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 languag
31、e relative to any evolving technology, either in the requirements or explanatory area of this standard, in no way infers acceptance or rejection of such technologies. Inquiries with respect to the application or the substantive requirements of this standard and suggestions for its improvement are we
32、lcomed, and should be sent to the B11 Standards, Inc., POB 690905, Houston Texas, 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
33、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 Subcommittee recommend
34、s 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 recognized risk assessm
35、ent methods within 30 months of the approval 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. This standard was processed and submitted for ANSI approval by th
36、e 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 document was approved as an American National Standard, the ANSI B11 Accredited Standards Com
37、mittee was composed of the following member organizations: John W. Russell, PE, CSP Chairman Gary D. Kopps, Vice-Chairman David A. Felinski, Secretary Organizations Represented Name of Representative Delegate Alternate Aerospace Industries Association of America Willard J. Wood Robert J. Eaker, PE,

40、tries Federation Dennis Cloutier, CSP Teresa F. Stillman Natl. Inst. for 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 action. Similarly, the term “CAN” denotes a possi
41、bility, ability 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 are of such nature as to be vital s
42、afety requirements, equal in weight to other requirements, or guides to assist in compliance with the standard. The B11 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. A distinction between the terms “individual
43、” 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, vend
44、ors, etc.). Gauge refers to a measuring or testing instrument; gage refers to limiting device (e.g., backgage). Suggestions for improvement of this standard will be welcome. They should be sent to B11 Standards, Inc. POB 690905, Houston TX 77269 - Attention: B11 Secretariat. viii Introduction The pr
45、imary purpose of every machine tool is to process parts. During production, maintenance, commissioning and de-commissioning, hazards exist that may result in injury. The primary purpose of the ANSI B11 series of machine tool safety standards is to devise and propose ways to minimize risks of the pot
46、ential hazards. This can be accomplished either by an appropriate machine design, by restricting personnel or other individuals access to hazard areas, and by devising work procedures to minimize personnel exposure to hazardous situations. The responsibility for the alleviation of these risks is div
47、ided between the equipment supplier, the equipment user and its operating personnel, as follows (numbers in parentheses refer to the clause numbers in these standards which address that responsibility): AMERICAN NATIONAL STANDARD B11.202004 (R15) 1 American National Standard for Machines Safety Requ
