Technical Standards

Prenecon's Technical Standards


Technical Standards is an establishment norm or requirements about technocal systems. Is is usually a formal document that establishes uniform engineering or technical criteria, methods, process and practices.

EC-1: Basis of design and actions on structures

EC-2: Design of reinforced concrete structure

EC-7: Geotechnical design and foundations

EC-8: Earthquake resistant design and structures

IEC 61400-1: Loads of wind turbine generations systems

IEC 60502: Power cables with extruded insulation and their accesories for rated volatages from 1KV up to 30KV


EuroCodes (EC)

Are a set of pan-European model building codes, developed by the European Committee for Standardisation. The Eurocodes form a common European set of structural design codes for civil engineering work.By March 2010 the Eurocodes will be mandatory for European public works and likely to become the de-facto standard for the private sector. The Eurocodes will therefore replace the existing national codes published by national standard bodies (e.g.  BS, DIN, etc), although many countries will have a period of co-existence. At the moment some Eurocodes are still in a trial phase, so they are characterised as ENV instead of EN until they are officially adopted. Additionally, each country is expected to issue a National Annex to the Eurocodes which will need referencing for a particular country (e.g. The UK National Annex)

International Electrotechnical Commission



Is a non-profit, non-governmental international standards organization that prepares and publishes International Standards for all electrical, electronic and related technologies – collectively known as "electrotechnology". IEC standards cover a vast range of technologies from power generation, transmission and distribution to home appliances and office equipment, semiconductors, fibre optics, batteries, solar energy, nanotechnology and marine energy as well as many others. The IEC also manages three global conformity assessment systems that certify whether equipment, system or components conform to its International Standards.The IEC charter embraces all electrotechnologies including energy production and distribution, electronics, magnetics and electromagnetics, electroacoustics, multimedia and telecommunication, as well as associated general disciplines such as terminology and symbols, electromagnetic compatibility , measurement and performance, dependability, design and development, safety and the environmen.
