General Information
Frequently Asked Questions
CEN/TC 349/WG 2 is a Working Group within the European Committee for Standardization (CEN). It is named "Sealants for glazing". This committee has published 4 standards.
CEN/TC 349/WG 2 develops CEN standards. Currently, there are 4 published standards from this working group.
The European Committee for Standardization (CEN) is a public standards organization that brings together the national standardization bodies of 34 European countries. CEN provides a platform for developing European Standards (ENs) and other technical documents in relation to various products, materials, services, and processes, supporting the European Single Market.
A Working Group in CEN is a specialized group responsible for developing standards or technical work within a defined scope. These bodies bring together international experts to create consensus-based standards that support global trade, safety, and interoperability.
This document covers the requirements for, and testing of sealants for use in one or more of the following applications:
a) Manufacturing of insulating glass units where direct ultraviolet resistance and mechanical resistance (bonding use) of the insulating glass edge seal are required;
b) Manufacturing of factory-made bonded sealant glazing elements when referred to by the relevant European Standards and/or European Technical Approval Guidelines;
c) Assembling of glass products into or onto supports, where also direct ultraviolet resistance and/or mechanical resistance (bonding use) of the seal are required, under controlled environmental conditions as described in EN 13022-2.
This document covers the evaluation of conformity and the factory production control with respect to the production of sealants in conformity with this document.
This document describes the role of sealants that are in conformity with this document, with respect to sealing and bonding.
This document does not apply to sealants for the manufacture of insulating glass units where the seal is fully protected, i.e. by a frame, from ultraviolet radiation.

This European Standard specifies definitions and requirements for non-structural elastic sealants used for sealing glazing in building construction applications.
It covers glazing joints from 7° horizontal. Main areas of application are:
- glass to glass;
- glass to frame;
- glass to porous substrates.
Excluding aquariums, structural bonding/glazing, inner and outer seal to manufacture insulated glazing units, horizontal glazing (below 7°), organic glass (e.g. polycarbonate, PMMA, etc.).
