The logo of the European Committee for Standardization for aluminium recycling. The European Committee for Standardization (CEN, French: Comité Européen de Normalisation) is a public standards organization whose mission is to foster the economy of the European Single Market and the wider European continent in global trading, the welfare of European citizens and the environment by providing ...
The Richter scale [1] (/ ˈ r ɪ k t ər /), also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, [2] is a measure of the strength of earthquakes, developed by Charles Richter in collaboration with Beno Gutenberg, and presented in Richter's landmark 1935 paper, where he called it the "magnitude scale".

In the Eurocode series of European standards (EN) related to construction, Eurocode 2: Design of concrete structures (abbreviated EN 1992 or, informally, EC 2) specifies technical rules for the design of concrete, reinforced concrete and prestressed concrete structures, using the limit state design philosophy.
After the Dresden Agreement (1996), CENELEC coordinates standard development activities with IEC.Older IEC standards were converted in 1997 by adding 60000, for example IEC 27 became IEC 60027 and the same standards are also published in the EN 60000 series to indicate adoption by CENELEC as a European standard; for example IEC 60034 is also available as EN 60034.
Seismic magnitude scales are used to describe the overall strength or "size" of an earthquake. These are distinguished from seismic intensity scales that categorize the intensity or severity of ground shaking (quaking) caused by an earthquake at a given location. Magnitudes are usually determined from measurements of an earthquake's seismic ...
Logo of Eurocode 8. In the Eurocode series of European standards (EN) related to construction, Eurocode 8: Design of structures for earthquake resistance (abbreviated EN 1998 or, informally, EC 8) describes how to design structures in seismic zone, using the limit state design philosophy. It was approved by the European Committee for ...

Eurocodes 1 – 9 are organised thematically, here illustrated downwards from left to right: 1: snow load, 2: concrete bridge, 3: steel bridge, 4: composite, 5: timber house, 6: masonry, 7: sheet pile wall, 8: earthquake and 9: aluminium structure. The Eurocodes are published as a separate European Standards, each having a number of parts.
