Are you prepared for the introduction of the NEN-EN1090-1?
The NEN-EN1090-1 became effective as of 1 January 2011 as a harmonized European standard. During the transition period, clients may prescribe a CE Declaration of Conformity for Construction Parts. After the transitional period, from 1 July 2012, a CE marking and CE Declaration of Conformity will be a legal obligation for all structural steel and aluminum construction parts.
The NEN-EN1090-2 was published in August 2008 and is the manufacturing standard for steel structures, from simple bolted structures to heavily dynamically welded structures such as a railway bridge.
The requirements to be manufactured are determined by performance classes, which are again dependent on the result class (possible chance of human casualties and economic damage), the use category (for example, dynamic or static) and the product category (for example, bolted or Welded constructions).
The NEN-EN1090-2 indicates which bolt connections may be applied. Tightening joints according to EN14399 and non-tensioned bearing bolt connections EN15048 may be applied.
