EN 15434:2006 (E) 5 Foreword This European Standard (EN 15434:2006) has been prepared by Technical Committee CEN/TC 129 “Glass in building”, the secretariat of which is held by IBN/BIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2006, and conflicting national standards shall be withdrawn at the latest by November 2006. This European Standard is one of a series of interrelated standard parts dealing with: - glass products for structural sealant glazing systems; - installation of glass products in a structural manner on building façades; - UV-resistant and structural sealant for use in structural sealant glazing The interrelated parts are:  EN 13022-1: Glass in building — Structural sealant glazing — Part 1: Glass products for structural sealant glazing systems for supported and unsupported monolithic and multiple glazing  EN 13022-2: Glass in building — Structural sealant glazing — Assembly rules  EN 15434: Glass in building — Product standard for structural and/or ultra-violet resistant sealant (for use with structural sealant glazing and/or insulating glass units with exposed seals) According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.



EN 15434:2006 (E) 6 1 Scope This European Standard covers the evaluation of conformity and the factory production control of sealant for the intrinsic capabilities when intended to apply for:  manufacturing of insulating glass units where ultra-violet resistance and/or mechanical resistance (structural use) of the insulating glass edge seal is required:  required level of resistance to UV exposure will depend on the degree of exposure to UV radiation with or without protection;  when the outer seal of the insulating glass has a structural function and/or is exposed to the UV radiation without any protection, only silicone based sealants are permitted;  when the outer seal of the insulating glass has no structural function and is protected from direct exposure to UV radiation, organic and silicone based sealants are permitted;  manufacturing of factory made structural sealant glazing elements when referred to by the relevant European Standards and ETAGs.
Only silicone based sealants are permitted;  assembling of glass products into or onto supports, where also ultra-violet resistance and/or mechanical resistance (structural use) of the seal is required under controlled environmental conditions as described in Clause 5 of EN 13022–2:2006.
Only silicone based sealants are permitted. This European Standard also specifies requirements concerning seals and bonds of sealant in conformity with this European Standard.  When bonding of sealant to a non-glass substrate is tested, the substrate, which means the material, its treatment and its preparations for bonding, as applied or to be applied on the work is used in testing (coating of coated glass is considered as a non-glass substrate). This European Standard contains other aspects of importance of trade. 2 Normative references The following referenced documents are indispensable for the application of this European Standard.
