20、n. This edition of BS5234 is being issued in two Parts. BS5234-1 deals with design and siteworks, and BS5234-2 specifies performance requirements for strength and robustness, including methods of test. A partition is now defined as “non-loadbearing” and accordingly this adjective no longer appears i
21、n the title. Definitions of different types of partition are now given. The recommendations given are applicable to all partitions including masonry partitions, but the standard makes no reference to specific materials and methods used in their construction. Masonry should be designed in accordance
22、with the recommendations given in BS5628-1, BS5628-2and BS5628-3. Information on other forms of partition construction is given in BS5268-6 and BS8212. Partitions have now been given grades. These relate to the level of activity in adjacent spaces and the degree of care the partition is likely to re
23、ceive. Grades are defined by the strength and robustness of a sample partition when tested by the methods described in BS5234-2. A summary of performance criteria for grades of partitions is given in Annex B. Assessed capability. Users of this British Standard are advised to consider the desirabilit
24、y of quality system assessment and registration against the appropriate Part of BS5750 by a third party certification body. Enquiries as to the availability of third party certification schemes are forwarded by BSI to the Association of Certification Bodies. If a third party certification scheme doe
25、s not already exist, users should consider approaching an appropriate body from the list of Association members. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a Brit
26、ish Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pagesi to iv, pages1to30, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments inco
27、rporated. This will be indicated in the amendment table on the inside front cover.BS5234-1:1992 BSI 07-1999 1 Section 1. General 1.1 Scope This Part of BS5234 gives recommendations for the design and installation of partitions. Types of partition are defined and the functions and properties of parti
28、tions to be considered are given. Recommendations for ensuring that the design is realized on site and maintained after completion are given. Partitions are graded by their categories of duty, assessed against performance criteria when sample partitions are tested for strength and robustness by the
29、methods given in BS5234-2:1992. The performance requirements are for partitions complete with their surface finishes where these are part of the partition specification. Performance requirements specific to special purpose partitions are not included. Examples of excluded properties are: structural
30、stability of screens; thermal insulation to cold store partitions; sound absorption of partitions to large auditoria; bullet-resistance of glazed high security partitions (see BS5051-1); X-ray resistance of partitions (see HTM56 1) )1; all properties of patent glazing partitions (seeBS5516). 1.2 Ref
31、erences 1.2.1 Normative references This Part of BS5234 incorporates, by reference, provisions from specific editions of other publications. These normative references are cited at the appropriate points in the text and the publications are listed on page 30. Subsequent amendments to, or revisions of

Editions of these publications current at the time of issue of this stand
33、ard are listed on the inside back cover but reference should be made to the latest editions. 1.3 Definitions For the purposes of this Part of BS5234 the definitions given in BS6100 apply. Terms which are particularly relevant are reproduced together with others not in BS6100. Illustrations of some t
