CE Image

CE Marking. The CE marking or formerly EC mark, is a mandatory conformity marking for products sold in the European Economic Area (EEA) since 1993. The CE marking is the manufacturer's declaration that the product meets the requirements of the applicable EC directives.

Existing in its present form since 1993, the CE marking indicates the compliance with EU legislation of a product, wherever in the world manufactured, and enables its free movement within the European market. By affixing the CE marking on a product, a manufacturer is declaring, at its sole responsibility, conformity with all of the legal requirements to achieve CE marking which allows free movement and sale of the product throughout the European Economic Area. CE marking is intended for national market surveillance and enforcement authorities.

The Construction Product Regulations(EU) No305/2011(CPR) – The Construction Product Regulations 2011 – officially became a legal requirement on the 1st of July 2013 requiring all door-windows products manufactured from that date to carry a CE marking label relating directly to the product/product family. The CE marking label and Declaration of Performance will carry specific information pertaining to the legal requirements of CE marking for the product(s).

It is the manufacturer's (Sidey) responsibility to carry out the conformity assessment, to set up the technical file, and to issue the declaration of conformity-performance and above all to affix the CE marking to a product. Documentation is available here
