It includes many more parameters than BS which devotes 9 pages including figures, whilst BS EN contains some pages. Surge protection devices SPDs were not required previously to comply with older standards.

General principles Part 2: In BSthe protection of electronic equipment is only included in an informative annex. It does not, however, take into account the economic value of consequential losses from ligbtning downtime. Its purpose is to provide a procedure for the evaluation of such a risk.

Abstract This British Standard provides guidance on the design of systems for the protection of structures against lightning and on the selection of materials.

Call to action for investment in training. The BS British Standard on lightning protection has existed for decades.

This British Standard provides guidance on the design of systems for the protection of structures against lightning and on the selection of materials. Part 1 General principles This is an introduction to the other parts of the standard. The existing fabric and layout of a building may make readily apparent zones, or LPZ techniques may have to be applied to create the required zones. A lightning protection system commissioned or installed on a structure prior to this date should be maintained to BS Protection of offshore oil and gas installations does not fall within the scope of this British Standard.

BS EN is the latest reference document for protection against lightning.

However, BS EN details the use of air rods or finials, catenary or suspended conductors or a meshed conductor network, in any combination. This standard includes the following cross references: Guidance is provided on how to assess the risk of being struck and how to compile an index figure as an aid to deciding whether a particular structure is in need of protection.


In cases of difficulty, specialist advice should be sought. Lightning Protection – Out with the old, in with the new StrikeRisk for lightning calculations Overvoltage – When lightning strikes. Physical damage to structures and life bss Part 4: BS EN will take some time for people to fully interpret and comprehend, but by using the resources available, the issues they may initially encounter certainly lighttning be mastered.

When applying bonding, shielding and SPDs, technical lrotection must be balanced with economic necessity.

The four parts are as follows:. BS recommends the inspection of any LPS annually.

Guidance protsction also provided on the protection of electronically stored data. LPZ 1 sees limited induced current and damped magnetic field whilst LPZ 2 has a further reduction of induced current and further damped magnetic field.

British Standards relating to Lightning Protection

However, for an existing structure, retrofitting a set of co-ordinated SPDs is likely to be the easiest and most cost-effective solution.

The new standard consists of four parts: It is the British edition of the European standard to which all lightning protection systems to new structures, and new extensions to existing ones, are now designed, installed and maintained.

Electrical and electronic systems within buildings. Overview Product Details Code of practice for protection of structures against lightning Executive summary Code of practice for the design of systems for the protection of structures against lightning.

If the actual risk R is lower than the tolerable risk RTthen no protection measures are needed. So there may be a heavy duty lightning current Type I SPD at the service entrance to handle the majority of the surge energy, plus downstream overvoltage SPDs to protect terminal equipment. The first stage of the risk assessment is to identify the types of loss that a structure and its contents can incur. BS EN comprises four parts and these detail the fundamental requirements for lightning protection systems for the external and internal parts of a structure.

For new builds, bonding and screening measures can be integrally designed to form part of the complete lightning protection measures system LPMS. Prktection who bought this product also bought BS BS EN came into force on 1 September Moreover, established suppliers of lightning protection solutions are now offering a wealth of quality lightnign tools. This British Standard outlines the general technical aspects of lightning, illustrating its principal electrical, thermal and mechanical effects.

For example, consider the mesh sizes for an air termination network and spacing of down conductors in BS EN BS EN provides the requirements for protection of a structure against physical damage by means of a lightning protection system LPSand for protection against injury to living beings due to touch and step voltages in the vicinity of an LPS. September Replaced By: A series of trial and error calculations is then required in order that a sufficient level of lightning protection can be defined.
