It supersedes BS 1722-14:1992, which is withdrawn. BS 1772 is published
12、 in the following parts: Part 1: Specification for chain link fences; Part 2: Specification for strained wire and wire mesh netting fences; Part 4: Specification for cleft chestnut pale fences; Part 5: Specification for close-boarded fences and wooden palisade fences; Part 7: Specification for woode
13、n post and rail fences; Part 8: Specification for mild steel (low carbon steel) continuous bar fences and hurdles; Part 9: Specification for mild steel (low carbon steel) fences with round or square verticals and flat horizontals; Part 10: Specification for anti-intruder fences in chain link and wel
14、ded mesh; Part 11: Specification for woven wood and lap boarded panel fences; Part 12: Specification for steel palisade fences; Part 13: Specification for chain link fences for tennis court surrounds; Part 14: Specification for open mesh steel panel fences; Part 16: Specification for organic powder
15、coatings for use as a plastics finish to components and mesh. The various parts specify requirements for the types of fence that are considered suitable for standardization. It should be noted that no attempt has been made to standardize fences or gates of a purely decorative nature, nor to specify
16、requirements for “patent” proprietory fencing systems. It is recommended, however, that such fences or gates should be designed in accordance with the relevant clauses of this part of BS 1722. The principal changes introduced in this edition are to bring the requirements up to date with other parts
17、of BS 1722 and to accommodate changes in cross references to other standards. This edition also introduces requirements for very high security fences and for concrete posts for fences. This standard aims to establish minimum performance requirements for materials and workmanship. It specifies requir
18、ements for open mesh steel panel fences of four types: a) a fence for boundary or general purposes up to 2 400 mm in height; b) a fence for security purposes of minimum 2 400 mm in height; c) a fence for high security use of minimum 3 000 mm in height; d) a fence for extra high security of minimum 3
19、 000 mm in height. The general purpose fence is intended for use as a boundary marker or for those locations where it is deemed necessary merely to deter the casual intruder or trespasser. The security fence is designed for use in areas where greater protection is required from vandalism or trespass
20、, and can be considered suitable for use for general industrial security such as for industrial estates, airfields and oil installations. The high security fence is designed for areas where protection against determined intrusion is required. However, it should be appreciated that it is not possible
21、 to install a fence that cannot be negotiated by a determined intruder given adequate time, freedom from observation and suitable climbing aids or tools for forcing an entry. The extra high security fence does not permit finger holds and therefore cannot be scaled without climbing aids. Licensed Cop
22、y: sheffieldun sheffieldun, na, Fri Nov 24 08:21:54 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS 1722-14:2001 BSI 08-2001 iii Choosing a fence is affected by factors such as the intended purpose, desired service life, aesthetic consideration and availability of components. The specifier can match a
23、 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 characteristics required. 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 desirab
24、le. The posts and struts 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 agreed with the specifier. NOTEThe s
25、ervice life/durability is dependent on environmental conditions and may vary considerably. For this reason service life/durability is not included in this standard. For information relating to finishes and durability refer to the manufacturer. This standard specifies requirements for fence materials
26、 and their combination and installation to provide a serviceable fence. Because a fence is made up of a number of separate components, of which the particular features may vary, a number of permissible combinations are available to the user. When preparing a specification for a fence, it is therefor
27、e important to give precise details of the requirements of the fence and of the site. Annex A provides details of the fence requirements and installation site that should be agreed between the fence supplier and purchaser. However, as conditions vary from site to site, Annex A should not be assumed
28、to be exhaustive. It 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 either: a) have achieved the appropriate National Vocational Qual
29、ification (NVQ) or Scottish Vocational Qualification (SVQ) in fence installation (Level 2) relevant to this part of BS 1722; or b) be currently registered for the appropriate NVQ or SVQ in fence installation (Level 2) relevant to this part of BS 1722 provided such registration has not been in place
30、for a period greater than 5 years from the date of registration without successful assessment having taken place. Annex A and Annex G are informative. Annex B, Annex C, Annex D, Annex E and Annex F are normative. A British Standard does not purport to include all the necessary provisions of a contra
31、ct. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

34、rity fences at least 3 000 mm high; d) category 4: extra high security fences at least 3 000 mm high. Requirements for the performance of panel fences for this standard are based upon loadings described in clause 5. Maintenance of the fence after installation is outside the scope of the standard. NO
