CE The abbreviation stands for European Community and documents a product's compliance with the relevant EU guidelines. Every manufacturer, whether located in the EU or elsewhere, must apply the CE mark to all products that fall into the jurisdiction of EU guidelines.
The mark is not aimed at consumers. The CE mark is an administrative mark. It is a kind of "Technical passport", denoting compliance with the minimal requirements of the EU guidelines - meaning the products need not be sent to a testing site. The CE mark is hence no proof of tested quality.
