8、ed by BSI and came into effect on 30 November 2006. It was prepared by Technical Committee B/201, Fences and gates. A list of organizations represented on this committee can be obtained on request to its secretary.SupersessionThis part of BS 1722 supersedes BS 1722-10:1999, which is withdrawn.Relati

13、d that no attempt has been made to standardize fences or gates of a purely decorative nature, or to suit special requirements; nor to specify requirements for “patent” proprietary fencing systems. It is recommended, however, that such fences or gates should be designed in accordance with the relevan

14、t clauses of this part of BS 1722.1)Obsolescent.2)Part 18 is in development and will be published as a Draft for Development (DD). BSI 2006 iiiBS 1722-10:2006This standard aims to establish minimum requirements for material and workmanship of the more common types of fence in order to ensure satisfa

15、ctory service for the purchaser, and to assist manufacturers and installing contractors 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 should be constructed.Choosing a fence is

16、 affected by factors such as intended purpose, desired service life, aesthetic considerations and availability of components. The specifier can match a suitable choice of fence to its intended purpose by reference to Table 1 and Table 2 and also inform those installing the fence of the basic charact

17、eristics required.Premature failure of the fence can be avoided by taking care not to damage protective treatments during installation.This standard specifies the requirements for anti-intruder wire mesh fences. It may be used as a specification for work to be carried out by a specialist fencing con

18、tractor or, if such a contractor is not available, by local labour under strict supervision, with component parts supplied by firms approved by the purchaser.The specification given in this standard is suitable for use in industrial estates, airfields, oil and gas installations, etc. where an enhanc

19、ed level of security over fences conforming to BS 1722-1 is required. Other types of enhanced security fences are specified in BS 1722-12 security palisade (SP) fences and in the relevant clauses of BS 1722-14.It should be noted that throughout this part of BS 1722 fence post spacings are given in t

20、erms of centre-to-centre distances.Ground conditions may indicate that a variation in the length of a post or strut, or the depth to which it should be set, is desirable. The post and strut setting depths specified in this standard are intended for use in normal ground conditions but if special cond

21、itions exist that warrant a change in the specification, e.g. the ground is softer or firmer than usual, such a change should be agreed with the specifier. This also applies to other similar changes.Use of this documentIt has been assumed in the drafting of this part of BS 1722 that the execution of

22、 its provision is entrusted to appropriately qualified and experienced people. Before installation commences the Lead Installer should hold a current FISS/CSCS registration card skilled level (blue card) or equivalent and all other operatives should hold the basic fence operative card (green card) o

23、r equivalent.At the time 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/CSCS maintains a national register of fence installers and operatives. There might

24、 be other schemes available.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”.BS 1722-10:2006iv BSI 2006Commentary, explanation and general informative mat

25、erial is presented in smaller italic type, and does not constitute a normative element.Requirements in this standard are drafted in accordance with The BSI guide to standardization Section 2: Rules for the structure, drafting and presentation of British Standards, subclause 11.3.1, which states, “Re

26、quirements should be expressed 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 no

27、t purport to include all the necessary provisions of a contract. Users are responsible for its correct application.Compliance with a British Standard cannot confer immunity from legal obligations. BSI 2006 1BS 1722-10:20061 ScopeThis part of BS 1722 specifies requirements for anti-intruder chain lin

28、k or welded mesh fences and gates of at least 2.4 m in height for situations that require a higher level of protection than that offered by fences conforming to BS 1722-1. It also includes requirements for the installation of the fencing at the specified location.Provision is made for either single

29、or double extension arms.This standard includes requirements for component dimensions, together with the permissible tolerances on size. These are minimum requirements and it should normally be acceptable to use larger sizes, except if this could otherwise adversely affect the fitting of components

30、or if replacement parts are required to match with those already present.This standard includes requirements for protective treatments. However, maintenance requirements for the fence after installation are outside the scope of this standard.It specifies concrete or steel posts and struts, steel gat

31、es and gate posts and zinc coated or plastic coated zinc coated wire or mesh infill.This standard specifies requirements for fence materials and their combination and installation. Because a fence is made up of a number of separate components of which the particular features vary, e.g. zinc coated o

32、r plastic coated wire, a number of combinations are available to the user. Annex C provides details of the fence requirements and installation site that should be agreed between the fence supplier and purchaser at the time of ordering a fence. However, as conditions vary from site to site, Annex C s

33、hould not be assumed to be exhaustive.2 Normative referencesThe following normative documents contain provisions which, through reference in this text, constitute provisions of this part of this British Standard.
