1、/I Single-Tier Steel Bracket I Library Shelving About the National Information Standards Series NISO Standards are developed by the Standards Committees of the National Information Standards Organization. The development process is a strenuous one that includes a rigorous peer review of proposed sta
2、ndards open to each NISO Voting Member and any other interested party. Final approval of the standard involves verification by the American National Standards Institute that its requirements for due process, consensus, and other approval criteria have been met by NISO. Once verified and approved, NI
3、SO Standards also become American National Standards. The use of an ANSI/NISO Standard is voluntary. That is, the existence of this NISO Standard does not preclude anyone, whether or not that person has adopted the NISO Standard, from manufacturing, marketing, purchasing, or using products, processe
4、s, or procedures that do not conform to the NISO Standard. However, the use of standards (those developed by NISO as well as other standards-developing organizations) has proven to be in the best interests of any industry wishing to increase its effectiveness and efficiency in the areas of product d
5、evelopment, manufacturing, and marketing and, therefore, such use is encouraged by ANSI, NISO, and all other standards-developing organizations. Every NISO Standard is reviewed at least once every five years to confirm that the NISO Standard remains viable and useful in its current environment. Comm
6、ents for revision are welcome at any time from any interested party. Proposed changes to this NISO Standard or suggestions for new NISO Standards should be sent to the NISO office at P.O.

It is included for informat
23、ion only.) In 1988 the Equipment Committee of the Build- ings and Equipment Section of the American Library Associations Library Administration and Management Association asked Library Technology Reports to undertake a comprehen- sive study of library shelving. This standard is based on the results
24、of that study as well as earlier research sponsored by LTR and the Library Technology Program. It was prepared by Howard S. White, editor, Library Technology Reports, American Library Association. An early draft of this standard was approved by an ad hoc Library Shelving Subcommittee that met in the
25、 early 1980s. Representing vari- ous library shelving companies were the fol- lowing industry representatives: Andrew Fenton, Thomas E. Hovey, Bruce Pike, Lawrence Rice, and Robert Trelease. Repre- senting the interests of libraries were Nancy McAdams, a facilities planner for the Univer- sity of Te
26、xas at Austin; Robert Rohlf, director, Hennepin County Library and a well-known library buildings consultant; and Frazer Poole, internationally acclaimed library facilities ex- pert and also the first executive director of ALAS Library Technology Program from 1959 to 1963. Howard C. White, editor of
27、 Library Technology Reports, was the secretary to this subcommit tee. Suggestions for improving this standard are welcome. They should be sent to the National Information Standards Organization, P.O. Box 1056, Bethesda, MD 20827, (301) 654-2512. This standard was processed and approved for sub- mitt
28、al to ANSI by the National Information Standards Organization. NISO approval of the standard does not necessarily imply that all Voting Members voted for this standards ap- proval. At the time it approved this standard, NISO had the following Voting Members: NISO Voting Members American Association

45、239.73-1994 Single-Tier Steel Bracket Library Shelving 1. Scope 1.1 Description This standard establishes minimum performance requirements for the steel shelving generally known as single-tier bracket (freestanding) bookstack, consisting of two upright support columns per modular section with adjust
46、able shelves cantilever-hung on brackets on both sides of the uprights. Such shelving conforms to three criteria. 1.1.1 Shelf Length and Width Shelves are of uniform lengths and widths, formed of sheet metal, with cantilever-hung brackets that secure the shelves to the uprights. 1.1.2 Shelf Adjustab
47、ility Shelves are easily adjustable up and down, in one-inch increments, without tools. 1.1.3 Design Use This shelving is designed primarily for use in libraries. 1.2 Exclusions It is not the purpose of this standard to describe the weight, thickness, composition, size, or con- figuration of structu
48、ralmembers, nor the method of application, composition, or thickness of the finish. This standard does not apply to the kinds of shelving described below in 1.2.1 and 1.2.2. 1.2.1 Four-Post Shelving Four-post shelving consists of four angle-iron uprights per section with shelves hung by bolts or cli
49、ps, designed primarily for use in ware- houses or for industrial or commercial storage. 1.2.2 Case Shelving Case shelving consists of full panel backs and tops, and end panels made to receive the shelves in slots. 1.3 Application Although requirements for steel bracket shelv- ing may differ somewhat according to the kind of library and its collections, this standard speci- fies the minimum performance characteristics for such shelving for book collections in public, school, academic, and research libraries in the United States. 2.
