16、e fences or gates of a purely decorative nature, or those to suit special requirements; or to specify requirements for “patent” proprietary fencing systems. However, such fences or gates should be designed in accordance with the relevant clauses of this part of BS 1722.1) Obsolescent.2) Part 18 is i

17、n development and will be published as a Draft for Development (DD).The start and finish of text introduced or altered by Corrigendum No. 1is indicated in the text by tags .PQ BSI 2010 iiiBS 1722-2:2006This standard aims to establish minimum requirements for materials and workmanship for themore com

18、montypes offence in order toensure satisfactory service for the purchaser, and to assist manufacturers and installers by eliminating unnecessary minor variations in the demands of purchasers. It specifies requirements for the components that make up a fence and the way in which the fence needs to be

19、 constructed.The standard includes requirements for sizes of components, together with the permissible tolerances on size. These are minimum requirements and it is normally acceptable to use larger sizes, except if this could adversely affect the fitting of components or if replacement parts are req

20、uired to match up with those already present.Choosing a suitable fence is affectedby factors such as intended purpose, desired service life, aesthetic considerations andavailability ofcomponents. The specifier can match a suitable choice of fence to its intended purpose and also inform thoseinstalli

21、ng the fence of the basic characteristics required. Premature failure of the fence can be avoided by taking care not to overstrain coated wire or to damage protective treatments during installation.Ground conditions might indicate that a variation in the length of a postor strut, or the depth, to wh

22、ich it should be set, is desirable. The posts and struts and setting depths specified in this standard are intended for use in normal ground conditions, but if special conditions exist that warrant a change in the specification, e.g. the ground is softer or firmer than usual, such a change should be

23、 agreed with the specifier.Annex A specifies requirements for concrete components.Annex B specifies requirements for steel components.Annex C provides details ofthe fence requirements and installation site that should be agreed between the fence supplier and purchaser. NOTE Conditions vary from site

24、 tosite. Annex B should not be assumed to be exhaustive.Annex D specifies a method of measuring line wire tension.Annex E provides guidance on the determination of water content.Use of this documentIt has been assumed in the drafting of this part of BS 1722 that the execution of its provision is ent

25、rusted to appropriately qualified and experienced people. Before installation commences the Lead Installer should hold a current FISS/CSCS registration card skilled level (bluecard) or equivalent and all other operatives should hold the basic fence operative card (green card) or equivalent.At the ti

26、me of publication of this British Standard the registration cards are validated by the Joint Fencing Industry Skills Scheme(FISS) and Construction Scheme Skills Certification Scheme (CSCS). FISS/CSCSmaintains a national register of fence installers and operatives. There might be other schemes availa

27、ble. BSI 2010BS 1722-2:2006iv Presentational conventionsThe provisions of this standard are presented in roman (i.e. upright) type. Its requirements are expressed in sentences in which the principal auxiliary verb is “shall”.Commentary, explanation and general informative material is presented in sm

28、aller italic type, and does not constitute a normative element.Requirements in this standard are drafted in accordance with The BSIguide to standardization Section 2: Rules for the structure, drafting and presentation of British Standards, subclause 11.3.1, which states, “Requirements should be expr

29、essed using wording such as: When tested as described in Annex A, the product shall .”. This means that only those products that are capable of passing the specified test will be deemed to conform to this standard.Contractual and legal considerationsThis publication does not purport to include all t

30、he necessary provisions of a contract. Users are responsible for its correct application.Compliance with a British Standard cannot conferimmunity from legal obligations. BSI 2010 1BS 1722-2:20061ScopeThis part of BS 1722 specifies requirements for the construction and installation ofgeneral pattern

31、and dropper pattern strained wire fences and rectangular wire mesh fences, including mild steel or high tensile woven wire fencing, welded mesh fencing, hexagonal wire netting fences of the general pattern, and spring steel wire pattern fences where the mesh is fixed onto spring steel line wires.Thi

32、s standard includes requirements for protective treatments. However, maintenance requirements of the fence after installation are outside the scope of this standard.NOTE Figure 1 illustrates the general characteristics of strained wire fences. It is not intended to illustrateany particular requireme

33、nts of this standard but provides guidance as tothe general layout of a typical fence, and on the terminology associated with this form of fencing.2Normative referencesThe following referenced documents are indispensable for the application of this document.
