This British Standard also covers fences between 2.4 m and 3 m in height with components constructed to the SP specification.NOTE 1 Where greater resistance against penetration is required for fences below 2.4 m in height, the SP components should be obtained from the purchaser.NOTE 2 Requirements in this British Standard for the minimum sizes of fence components are based on a design wind loading, q, at right angles to the plane of the fence of 900 N/m2 employing a shape factor of 1.9 on the net area presented to the wind.NOTE 3 In situations of extreme exposure or abnormal loading, a special appraisal should be undertaken and the design criteria should be obtained from the purchaser.NOTE 4 The responsibility for ensuring the final installation meets this British Standard belongs to the installer. This responsibility can be mitigated by obtaining certificates for materials used from the suppliers (see Clause 10).Cross References:BS 4-1:2005BS 907BS 3692:2014BS 3693BS 4320BS 4484-1BS 4652BS 7371-3BS 7371-6BS 7805-1BS 8500-1:2015+A1:2016BS 8500-2:2015+A1:2016BS EN 1011-1BS EN 1011-2BS EN 10025-2:2004BS EN 10056-1:1999BS EN 10058:2003BS EN 10210-1:2006BS EN 10210-2:2006BS EN 10219-1:2006BS EN 10219-2:2006BS EN 10263-1BS EN 10263-2BS EN 10263-3BS EN 10263-4BS EN 10296-1:2003BS EN 12620BS EN ISO 376BS EN ISO 463BS EN ISO 1461:2009BS EN ISO 7500-1:2015BS EN 287-1BS EN 1176-1All current amendments available at time of purchase are included with the purchase of this document.
