Since February 1, 2010, CE marking has been mandatory for windows and exterior doors. The obligation for CE marking is regulated by the EU Directive 93/68/EEC and specific product standards. CE marking is a conformity symbol indicating that a product meets the requirements of European directives.

Standard DIN EN 14351-1

DIN EN 14351-1 pertains to windows and exterior doors made of wood and wood-aluminum, specifying the requirements for such products. The obligation for CE marking of windows and exterior doors is regulated by the harmonized standard DIN EN 14351-1. To obtain the CE marking for windows and exterior doors, manufacturers must ensure that their products meet the basic requirements for safety and performance. This involves conducting relevant tests and creating the necessary documentation, including a Declaration of Performance. The CE marking signifies that the product can be freely traded within the European Economic Area. CE-Fix generates all the required documents for you in a few minutes.
