CE Marking

Categories: Introduction

The format of the CE mark to be attached to a product is described in Annex ZA of the Harmonised European Standard for the product.

Annex ZA of a Product Standard lists the essential characteristics to be shown on the CE Mark. For each essential characteristic a value or class must be declared. npd (No performance declared) may be shown for a particular characteristic unless that characteristic is required by National Building Regulations or is listed as a mandatory requirement in the Product Standard.

A Declaration of Performance (DoP) is made by the Manufacturer. The CE Mark is attached to the product by the manufacturer to show compliance with the DoP. The CE mark cannot be attached by the maker of a window system or components unless they supply a complete kit including the glass. In the case of curtain walling the CE mark will be attached by the Specialist Contractor.

Annex ZA of a Product Standard shows the Level of Conformity (LoC) required.

For curtain walling Initial Type Testing (ITT) has to be carried out by a Notified Body after which a Manufacturer may self-attest that the product meets the performance declared on the CE label provided that the reaction to fire performance is not dependent on workmanship.

The CE Label is not necessarily physically affixed to the product:

For windows which may be sold as stand alone products alternate ways of CE marking are permitted and the CE mark may be;

For curtain walling which has an inherent element of project design the CE mark will be part of the contract documentation.

Glass and insulating glass units do not have to carry a CE mark on the product but supporting evidence should be available.
