Contents of the package:
1. BS 1722-1:2006 Fences. Specification for chain link fences
BS 1722-1 specifies requirements for chain link fences, 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.
2. BS 1722-2:2006 Fences. Specification for strained wire and wire mesh netting fences
3. BS 1722-5:2006 Fences. Specification for close-boarded fences and wooden palisade fences
4. BS 1722-7:2006 Fences. Specification for wooden post and rail fences
5. BS 1722-8:2006 Fences. Specification for mild steel (low carbon steel) continuous bar fences and hurdles
BS 1722-8 provides requirements for mild steel (low carbon steel) continuous bar fences for farm animal containment applications and welded hurdle fences of continuous bar type.
6. BS 1722-9:2006 Fences. Specification for mild steel (low carbon steel) fences with round or square verticals and flat horizontals
This British Standard, a part of the BS 1722 series, specifies requirements for self adjusting (nibbed) or welded mild steel (low carbon steel) fences with round or square verticals and rolled hollow section (RHS) or rolled steel joist (RSJ) posts and flat horizontals. It also specifies requirements for their installation.
This British Standard covers requirements for protective treatment. However, maintenance of the fence after installation is outside the scope of this standard.
This standard aims to establish minimum requirements for materials and workmanship of the more common types of fence in order to ensure 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 constructed. The standard includes requirements for sizes of components, together with the permissible tolerances on size.
The major changes in this revision are the removal of flat posts from the standard, the inclusion of RHS posts, removal of requirements for angle corner posts, which in this edition are specified as for line posts, and revision of the requirements for gates. The opportunity has also been taken to simplify the construction and installation requirements in line with current practice.
BS 1722-9 specifies requirements for self-adjusting (nibbed) or welded mild steel (low carbon steel) fences with round or square verticals and rolled hollow section (RHS) or rolled steel joist (RSJ) posts and flat horizontals. It also specifies their requirements for installation.
7. BS 1722-10:2006 Fences. Specification for anti-intruder fences in chain link and welded mesh
This part of BS 1722 specifies requirements for anti-intruder chain link 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. This British Standard also covers requirements for the installation of the fencing at the specified location. Provision is made for either single or double extension arms.
The aim of this standard is to establish minimum requirements for material and workmanship of the more common types of fence in order to ensure satisfactory service for the purchaser, and to assist manufacturers and erecting contractors by eliminating unnecessary minor variations in the demands of purchasers.
The specification given in this standard is suitable for use in industrial estates, airfields, oil and gas installation etc.
This revision of BS 1722-10 provides a more detailed specification for gates and locking devices. Further changes in this revision include clarification of the specification for posts and the use of heavier gate posts to act as fence strainers. The thickness of stirrup wire has been lowered to facilitate fixing of the mesh. Cube tests of concrete strength are now required and the frequency of testing is specified to ensure that regular quality checks are made.
8. BS 1722-11:2006 Fences. Specification for prefabricated wood panel fences
BS 1722-11 details requirements for the materials, design, construction and installation of prefabricated wood panel fences constructed from softwood panels, fixed between timber or concrete posts. This standard does not cover fences of a height greater than 2 m above ground level.
9. BS 1722-12:2006 Fences. Specification for steel palisade fences
This British Standard, a part of the BS 1722 series, specifies requirements for steel palisade fences and gates for general purposes (GP) in corrugated and angle pales for heights up to 2.4 m and for security (SP) purposes in corrugated pales for heights of 3.0 m and 3.6 m, all with posts at 2.75 m centres. This standard also covers fences between 2.4 m and 3.0 m in height with components constructed to the SP specification.
This standard specifies requirements for fence materials and their combination and installation.
In situations of extreme exposure or abnormal loading it will be necessary to carry out a special appraisal and for the design criteria to be specified.
10. BS 1722-14:2006 Fences. Specification for open mesh steel panel fences
BS 1722-14 specifies requirements for the following categories of open mesh steel panel fences:
Category 1: General purpose fences up to 2.4 m high;
Category 2: Security fences at least 2.4 m high;
Category 3: High security fences at least 3.0 m high;
Category 4: Extra high security fences at least 3.0 mm high.
Requirements for the performance of panel fences for this standard are based upon loadings.
The principal changes introduced in this edition are to bring the requirements up to date with other parts 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.
11. BS 1722-16:2009 Fences. Specification for powder coatings used as a plastics finish to components and mesh
Dear friends, if someone of you have the missing standards from this standard series, please share it.
