Basic Principles of European Standardisation

In order to ensure a unitary European set of standards, the following principles apply:

• Commitment to suspend activities:
  In the case of a standard being developed on a European level, no national standards-projects on the same topic may proceed to be developed simultaneously.
  
  
• Commitment to implement:
  European standards must be adopted into the national set of standards without alteration. In Austria, they are called ÖNORM EN. 
  
  
• Commitment to withdraw:
  National standards, which contradict European standards must be withdrawn.
