13、at no attempt has been made to standardize fences or gates of a purely decorative nature, or those suited to special requirements; nor to specify requirements for “patent” proprietary fencing systems. However, the structure of such fences or gates should be in accordance with the applicable clauses

14、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 1722-1:2006This standard aims to establish minimum requirements for materials and workmanship of the more common types of fence in order to ensure satisfactory serv

15、ice 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 needs to be constructed.Choosing a suitable fence i

16、s 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 char

17、acteristics required.Premature failure of the fence can be avoided by taking care neither to overstrain coated wire or to damage protective treatments during installation.Ground conditions might indicate that a variation in the length of a post or strut, or the depth to which these would be set, is

18、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 variations in the specification, e.g. the ground is softer or firmer than usual, such a change should be agreed with the specif

19、ier. Use of this documentIt has been assumed in the drafting of this part of BS 1722 that the execution of 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 (b

20、lue card) or equivalent and all other operatives should hold the basic fence operative card (green card) or 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 Certificat

21、ion Scheme (CSCS). FISS/CSCS maintains a national register of fence installers and operatives. There might 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 princip

22、al auxiliary verb is “shall”.Commentary, explanation and general informative material 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, dra

23、fting and presentation of British Standards, subclause 11.3.1, which states, “Requirements 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 confor

24、m to this standard.BS 1722-1:2006iv BSI 2006Contractual and legal considerationsThis publication does not 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.

25、 BSI 2006 1BS 1722-1:20061 ScopeThis part of BS 1722 specifies requirements for chain link fences and gates and gateposts for use with chain link fences. The gates specified are steel with a provision for chain link infill or other infill if required by the purchaser.NOTE For gates for domestic purp

26、oses, timber or “wrought iron” gates may be preferred. These types of gate are specified in BS 4092-1.This standard specifies requirements for fences up to 2.5 m in height with a chain link mesh infill. For other security fences, refer to BS 1722-10, BS 1722-12 and BS 1722-14, and for chain link fen

27、ces for tennis court surrounds refer to BS 1722-13.This standard specifies a method of allocating a reference code to each type of fence, indicating its height, the type and weight of infill, and the materials of the posts and the type of wire coating.NOTE These type references are given in Table 1

28、and Table 2. For uniformity the heights given in Table 1 and Table 2 are of the main infill material and exclude any ground clearance at the base or additional height provided by extension arms for barbed wire. Wire and chain link sizes are selected from BS EN 10223-6.This standard is divided into r

29、equirements for the material components for fences and for installation of the fences. This standard also includes requirements for protective treatments. However, maintenance requirements for the fence after installation are outside the scope of this standard.This standard includes requirements for

30、 sizes of components, together with the permissible tolerances on size. These are minimum requirements, and it will normally be acceptable to use larger sizes, except if this could adversely affect the fitting of components, or if replacement parts are required to match with those already present. 2
