5、ndard requires verifi-cation by ANSI that the requirements for due process, con-sensus, and other criteria for approval have been met by the standards developer.Consensus is established when, in the judgement of the ANSI Board of Standards Review, substantial agreement has been reached by directly a

6、nd materially affected inter-ests. Substantial agreement means much more than a sim-ple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution.The use of American National Standards is compl

11、of this American NationalStandard (ANS) and has not been processed in accordance with ANSIs require-ments for an ANS. As such, this foreword may contain material that has not beensubjected to public review or a consensus process. In addition, it does not containrequirements necessary for conformance

12、 to the standard.DevelopmentThe 1961 edition of ANSI Standard A117.1 presented the first criteria for accessibil-ity to be approved as an American National Standard and was the result ofresearch conducted by the University of Illinois under a grant from the Easter SealResearch Foundation. The Nation

13、al Easter Seal Society and the Presidents Com-mittee on Employment of People with Disabilities became members of the Secre-tariat, and the 1961 edition was reaffirmed in 1971.In 1974, the U.S. Department of Housing and Urban Development joined theSecretariat and sponsored needed research, which resu

14、lted in the 1980 edition.After further revision that included a special effort to remove application criteria(scoping requirements), the 1986 edition was published and, when requested in1987, the Council of American Building Officials (CABO) assumed the Secretariat.Central to the intent of the chang

15、e in the Secretariat was the development of astandard that, when adopted as part of a building code, would be compatible withthe building code and its enforcement. The 1998 edition largely achieved that goal.The 2009 edition of the standard is the latest example of the A117.1 committeeseffort to con

16、tinue developing a standard that is compatible with the building code.When CABO was consolidated into the International Code Council (ICC) in 1998,the Secretariat duties were assumed by ICC.2009 EditionNew to the 2009 edition are coordinated criteria for the various types of dwellingunits that provi

For example, it specifies technical requirements f

38、or making doors, routes, seating and other elements accessible. These accessi-ble elements are used for designing accessible functional spaces such as classrooms, hotel rooms, lobbies or offices.This standard does not include scoping criteria (i.e., what, where and how many). Scoping provisions are

39、contained in laws, ordinances or model building codes that reference this standard. This standard is for adoption by government agencies and by organizations setting model codes to achieve uniformity in the technical design criteria in building codes and other regulations. This standard is also used

40、 by nongovernmental entities as technical design guidelines or requirements to make buildings and facilities accessible to and usable by persons with physical disabilities.Provisions of this standard are suitable for: the design and construction of new buildings and facilities, including both spaces

41、 and elements, site improvements and pub-lic walks. remodeling, alteration and rehabilitation of existing construction. permanent, temporary and emergency conditions.Criteria are established for individual building spaces and elements. The intention is that these accessible spaces and elements combi

42、ne to provide accessibility throughout a building and related site facilities. General criteria, such as the minimum width of an accessible route, can apply to different building or site elements, including sidewalks, corridors and aisles between library stacks. Other criteria are for specific eleme

43、nts such as drinking fountains, water closets, sinks and lavatories.The principal purpose of the commentary is to provide a basic volume of knowledge and facts relating to building construction as it pertains to the regulations set forth in the ICC A117.1.In the chapters that follow, discussions foc

44、us on the full meaning and implications of the text. Guildelines suggest the most effective method of application, and the consequences of not adhering to the text. Illustrations are provided to aid understanding; they do not necessarily illustrate the only methods of achieving compliance.The format

45、 of the commentary includes the full text of each section, table and figure in the standard, followed immediately by the commentary applicable to that text. At the time of printing, the commentary reflects the most up-to-date text of the 2009 ICC A117.1. Each sections narrative includes a statement

46、of its objective and intent and usually includes a discussion about why the requirement commands the conditions set forth. Standard text and commentary text are easily distinguished from each other. All standard text is shown as it appears in the ICC A117.1 and all commentary is indented below the c

47、ode text with the symbol .Readers should note that the commentary is to be used in conjunction with the ICC A117.1 and not as a substitute for the stan-dard.

49、lish which occupancy or building types are covered and the extent to which each type is covered. Such requirements for application of this standard must be specified by the adopting authority, including which and how many functional spaces and elements are to be made accessible within each building type.The standard does not establish which or how many buildings, facilities and spaces or elements w
