Since March 2007 the standards series EN 50.xxx, that regulates the electrical apparatus for potentially explosive atmospheres, begin to being replaced by standards series EN 60.xxx.
Such standards incorporate directly the standards IEC of equal number and turn out, today, harmonized or in harmonization course, like indicated in “Official Journal of the European Union” n° C 306/2 del 15.12.2006, down loaded from web sitehttp://ec.europa.eu/enterprise/atex/index_en.htm
Therefore Ettore Cella SPA has conformed to the new harmonized standards bringing the necessary modifications to the product, to its certification, identification and marking.
