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 . It also includes requirements for the installation of the fencing at the specified location. Where enhanced levels of security are required, other types of fences are specified in BS 1722‑12 and in the relevant clauses of BS 1722‑14.

Provision is made for either single or double extension arms.

This British Standard includes requirements for component dimensions, together with the permissible tolerances on size. These are minimum requirements and it is acceptable to use larger sizes, except where this could adversely affect the fitting of components or if replacement parts are required to match with those already present.

This British Standard includes requirements for protective treatments. However, maintenance requirements for the fence after installation are outside the scope of this standard.

This British Standard specifies the requirements for posts, steel gates and gate posts and zinc coated or plastic coated zinc coated wire or mesh infill.

This British Standard also 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 or plastic coated wire, a number of combinations are available to the user. Annex A provides details of the fence requirements and installation site to be agreed between the fence supplier and client at the time of ordering a fence. However, as conditions vary from site to site, the information in Annex A is not exhaustive.

Ground conditions might indicate that a variation in the length of a post or strut, or the depth to which it can be set, is desirable. The post and strut setting depths specified in this part of BS 1722 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. This also applies to other similar changes.
