In each technical field, and in particular in the electrical sector, a condition sufficient (even if not necessary) for the realization of plants according to the “status of the art” and a requirement essential to properly meet the demands of customers and of the community, is the respect of all the relevant laws and technical standards.

Therefore, a precise knowledge of the standards is the fundamental premise for a correct approach to the problems of the electrical plants which shall be designed in order to guarantee that “acceptable safety level” which is never absolute

Juridical Standards These are all the standards from which derive rules of behavior for the juridical persons who are under the sovereignty of that State

Technical Standards These standards are the whole of the prescriptions on the basis of which machines, apparatus, materials and the installations should be designed, ma nufactured and tested so that efficiency and function safety are ensured.

The technical standards, published by national and international bodies, are circumstantially drawn up and can have legal force when this is attributed by a legislative measure.

IEC International Electrotechnical Commission

The International Electrotechnical Commission (IEC) was officially founded in 1906, with the aim of securing the international co-operation as regards standardization and certification in electrical and electronic technologies. This association is formed by the International Committees of over 40 countries all over the world.

The IEC publishes international standards, technical guides and reports which are the bases or, in any case, a reference of utmost importance for any national and European standardization activity.

IEC Standards are generally issued in two languages: English and French. In 1991 the IEC has ratified co-operation agreements with CENELEC (European standardization body), for a common planning of new standardization activities and for parallel voting on standard drafts.
