Abstract

It is possible that some of you here have never heard of CEN or if you have, have little idea as to what its function is.
CEN – COMITÉ EUROPEÉN de NORMALISATION or in English EUROPEAN COMMITTEE for STANDARDIZATION was set up by the European Council of Ministers.
The five aims of Standardization are:…
