2、stitute 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 AMT The Association For Manufacturing Technology (the ANSI-accredited standards develo
3、ping 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 necessarily unanimity.
4、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 AMT administers the process and es
5、tablishes 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 contained in its standards or guidelines. American Nationa
6、l 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 to the standards. However, users
7、, 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 will in no circumstances give an interpretation of an Amer

26、STANCE. 47 ANNEX E - APPLICATIONS AND ATTRIBUTES 56 iv American National Standard B11.192003 Foreword (This foreword is not part of the requirements of American National Standard B11.19-2003) The primary objective of this standard is to establish the requirements for the design, construction, instal
27、lation, operation and maintenance of the safeguarding (e.g., guards, safeguarding devices, awareness devices, safeguarding methods and safe work procedures) used to eliminate or control hazards to individuals associated with machine tools. This standard relies on other standards to determine which s
28、afeguarding is required or allowed to control identified hazards or hazardous situations, and is intended to be used in conjunction with the ANSI B11 “base” standard for a given machine tool. To accomplish this objective, this standard has established responsibilities for the safeguarding supplier (
29、e.g., manufacturer, rebuilder, installer, integrator and modifier), the user, and individuals in the working environment. The overall goal is to achieve safe work practices and a safe work environment. In addition, this standard includes a comprehensive informative Annex on safety distance, which ut
30、ilizes the updated Liberty Mutual anthropometric data. The original data, which OSHA (29 CFR 1910.217 Table 0-10) uses to base their safe distance safeguarding, was developed by Liberty Mutual in the 1940s. This data was updated and published in 1995, and used larger anthropometric surveys especiall
31、y relating to women and minorities. While the data sets are similar, several important modifications to the maximum gap size / minimum distance were suggested, and these modifications have been incorporated (see Table D.1 and Figure D.10, Annex D). The words “safe“ and “safety“ are not absolutes. Sa
32、fety begins with good design. While the goal of this standard is to eliminate injuries, this standard recognizes that risk factors cannot practically be reduced to zero in any human activity. This standard is not intended to replace good judgment and personal responsibility. Operator skill, attitude
33、, training, job monotony, fatigue and experience are safety factors that must be considered by the user. Safeguarding and associated equipment technologies are continuously evolving. This standard reflects the most commonly used and time-tested state of the art at the time of its approval. The inclu
34、sion 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 technologies. Inquiries with respect to the application or the substantive requirements of this standard, and suggestion
35、s for its improvement are welcomed, and should be sent to the AMT The Association For Manufacturing Technology, 7901 Westpark Drive, McLean, Virginia 22102-4269, Attention: B11 Secretariat. This standard was processed and submitted for ANSI approval by the B11 Accredited Standards Committee on Safet
36、y 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 standard was approved as an American National Standard, the ANSI B11 Accredited Standards Committee was composed of the following member o

Commet Karen Taylor General Motors Corporation Michael Taubitz v -,-,- American National Standard B11.192003 Graphic no deviation is permitted. The term “SHOULD” denotes a recommendation, a practice or
40、 condition among several alternatives, or a preferred method or course of action. Similarly, the term “CAN” denotes a possibility, ability or capability, whether physical or causal, and the term “MAY” denotes a permissible course of action within the limits of the standard. To achieve uniform interp
41、retation, it is imperative to read and understand the definitions (clause 3) of this 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 safety requirements, equal in weight to other requirements
42、, 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” and “personnel” is drawn. Individual includes personnel
43、 (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 instru
44、ment; gage refers to a limiting device (e.g., backgage). All Annexes are for information purposes only and are not normative parts of the standard. Suggestions for improvement of this standard will be welcome. They should be sent to AMT-The Association For Manufacturing Technology, 7901 Westpark Dri

46、ments of this American National Standard for Machine Tools - Performance Criteria for Safeguarding ANSI B11.192003) 1 Scope E1 This standard provides performance requirements for the design, construction, installation, operation and maintenance of the safeguarding listed below when applied to machin
47、e tools. a) Guards (see clause 7); b) Safeguarding devices (see clause 8); c) Awareness devices (see clause 9); d) Safeguarding methods (see clause 10); e) Safe work procedures (see clause 11); The manufacturer or supplier referred to in this standard is the manufacturer or supplier of the safeguard
48、ing, not the manufacturer or supplier of the machine tool (see clause 3 definitions of manufacturer and supplier). This standard does not provide the requirements for the selection of the safeguarding for a particular application. See the appropriate ANSI B11 machine tool safety standard for the req
49、uirements for the selection of safeguarding based on specific applications. Selection of the safeguarding requires task and hazard identification, and the application of risk assessment and risk reduction of the total production system. See ANSI B11.TR3 on risk assessment and risk reduction, and Annex E for additional guidance. 2 Normative references E2 Informati
