It has IEEE 998, EN 62305 NFPA 780 standards available to buy.

European standard committee (EN)

Develops standards. Has developed EN63205 and it has four parts

The International Electrotechnical Commission (IEC) is a body responsible for implementing international standards. Its

technical committees are comprised of representatives from various member national standards, where each country is

entitled to one vote during the process of creation and issuing the standard. The

standards generally have an IEC prefix to their number (CEI for

French versions). IEC standards are produced in English and French

languages. For most countries the adoption of these standards is

voluntary, and often selected content of the standard is absorbed

and introduced as improvements to that country’s own standard.Also, within Europe, there exists the European Committee

for Electrotechnical Standardisation (CENELEC). The member

countries currently include Austria, Belgium, Cyprus, the Czech

Republic, Denmark, Estonia, Finland, France, Greece, Hungary,

Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the

 Netherlands, Norway, Poland, Romania, Slovakia, Slovenia, Spain,

Sweden, Switzerland and the United Kingdom. IEC and CENELEC

generally work in parallel, and CENELEC members vote to adopt

new IEC standards as CENELEC standards. The committees of

CENELEC may choose to make some alterations to the IEC version.Additionally, CENELEC produce their own standards to which

IEC have no counterpart. CENELEC documents are produced in

English, French and German and an approved CENELEC standard

will have an EN prefix (or NE in the French language versions).

The important fact with CENELEC standards is that by rule the

member countries are bound to adopt all CENELEC standards as

national standards. In the process of adopting these standards,

minimum changes are permitted. In-country clauses (exceptions

or changes) can only be made under very strict circumstances.

When such standards are adopted at the national level, any

conflicting national standard must be withdrawn (an overlap

 period is permitted).

For the EN IEC 62305 series of lightning protection standards,

each member country has introduced these at a national level by

 November 2006 and has withdrawn any conflicting standards by February 2009.At each level (International, European,

 National) a different naming prefix convention is used For example:

•  IEC 62305-1 (IEC version)

•  EN 62305-1 (CENELEC adopted copy of the above)

•  BS EN 62305-1 (British National Standard adoption of

the above)
