CE Marking



CE Marking indicates that a product conforms to European technical standards known as harmonised European Norms (hEN), as dictated by the Comité Européen de Normalisation (CEN).

Each glass product sold in the European Union must now carry the CE mark, which can be affixed to the product, to its packaging or appear on the accompanying commercial documents.

The product must also be accompanied by a document detailing all the characteristics that meet the essential requirements. For Saint-Gobain Glass products, all this information can be found on our dedicated CE Marking website.

As a member of the Association of Glass for Europe, Saint Gobain Glass is committed to the various initiatives and directives required to ensure our products are CE Marked.

In the past, the Member States of the European Community imposed their own technical specifications and conformity checks on manufactured products.

Since 1985, European Community Directives have specified common technical requirements for each category of products, and procedures for assessing the conformity of these products.

The Construction Products Directive (CPD) applies to construction materials and more specifically to glass products used in building and construction.

The CPD is aimed at:

-Removing technical obstacles to business

-Enabling the largest possible number of manufacturers to access the market

-Ensuring the highest possible level of transparency in the market

-Creating the conditions for a harmonised system of general regulations applicable to the building industry.

The CPD covers the following aspects:

-Mechanical strength and stability

-Safety in the event of fire

-Health, safety and environment

-Safe use

-Protection against noise

-Energy saving and thermal insulation.

European Standards

The CEN (European Committee for Standardisation), and more specifically TC 129, has been mandated to produce harmonised European standards (hEN) in the field of "glass in building". This mandate covers "flat glass, profiled glass and moulded glass products" thus in particular the glass products manufactured, processed and sold by SAINT-GOBAIN GLASS and its SAINT-GOBAIN GLASS SOLUTIONS T&D network.

TC 129 has established various types of standard Basic standards

• Basic "product" standards, covering:

-The definitions of the product
-The characteristics of the product
-The generally accepted values.

• Basic "characteristics" standards, covering:

-The generally accepted values
-The calculation methods
-The methods for testing the performance of products

When they are published by the CEN, these standards replace all national standards relating to the same subject produced by the member bodies of the CEN.

Harmonised European standards (hEN)

These standards are compulsory and glass products sold in the European Union must comply with them.

Harmonised European Standards (hEN) are the standards that are also referred to as "Evaluation of the conformity of product to standard".

hENs cover the following aspects:

-Details of how the product conforms to the mandate
-Details of the initial type test of the product and its characteristics
-Details of factory production control

-Provisions of the directive on construction products in the European Union (appendix ZA to the standard).

On pages 484 to 486, a list is given of all the European standards (basic standards and harmonised European standards) concerning glass products used in building and construction.

The CE Mark signifies:

  • The product complies with corresponding harmonised product standards & all the provisions of the CPD
  • The product complies with the European technical specifications & has undergone  the appropriate conformity assessment procedures
  • The product is suitable for the intended use as defined by article 2(1) of the CPD
  • The product bearing this mark can freely cross national frontiers within the European Union
  • Products imported from non-community countries must also bear the mark as proof of their conformity.

Nevertheless, the fact that a product bears the mark in no way signifies that it can be used for any application.
The possible applications are regulated by current national regulations.

CE marking is NOT:

  • A mark of origin
  • A mark of quality in the conventional sense of the term
  • Connected with any aspects other than the essential requirements (eg: non-compulsory characteristics such as colour or appearance)
  • A licence to use the product in all work undertaken in all Member States. 

The CE marking can be affixed as soon as the hEN has been published in the Official Journal of the European Community and is implemented in one of the Member States.

At the time of publication of this GLASS GUIDE, the majority of the standards concerning glass in building have been published and are to become compulsory in the member countries of the European Community. The first glass products bearing the mark already appeared on the European market in 2005. The marking will become compulsory after a transition period during which the national standards of the countries and the European standards will exist side by side. This phase will enable countries and manufacturers to prepare for the implementation of marking. It is estimated that marking for all glass products will have become compulsory and replace national marks in 2007.

Manufacturers and producers will be wholly responsible for the certification indicating that products comply with the requirements set by a technical specification. Use of a notified body*, even for the provision of a certificate of conformity, does not release producers from their obligations.

Further Information

The standards have been established to remove technical barriers to trade for construction products.

A unique standard will exist for the major glass types/groups. These standards will supersede any national standards.
