3 European foreword This document (EN 16758:2016) has been prepared by Technical Committee CEN/TC 33 “Doors, windows, shutters, building hardware and curtain walling”, the secretariat of which is held by AFNOR. 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of an identical text or by endorsement, at the latest by December 2016, and conflicting national standards shall be withdrawn at the latest by December 2016. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

4 1 Scope This European Standard specifies test methods for the determination of bearing capacity (ultimate limit state and serviceability limit state), of connections between curtain walling framing members for which it cannot be calculated in accordance with current codes or conventional calculations based upon the strength of the materials. Mechanical performances of the curtain walling connections are already assessed in accordance with the provisions described in EN 13830. Additional information with respect to mechanical performance of the connections and direct applications can be determined with this standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 13119, Curtain walling - Terminology 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 13119 and the following apply. 3.1 connection set of components designed to transfer loads between framing members (e.g. cleat, screw) 4 Symbols For the purposes of this document, the following symbols apply. Fh,des design horizontal load Fv,des design vertical load Fu5 the characteristic force giving 75 % confidence that 95 % of the test results will be higher than this value s the standard deviation of the series under consideration u partial factor for the connection applicable to rupture ß statistical eccentricity of 5 % with 75 % confidence 5 Method of evaluation 5.1 General Connections are subjected to permanent loads as well as to variable loads. The measurement of the deformation is recorded at the application of the force. The support shall restraint vertical and horizontal movements. 5.2 Samples The samples shall be representative of the connection methods between the framing members of the curtain walling. SIST EN 16758:2016

5 Based on the type of curtain walling (e.g. stick construction, unitized system etc) different types of connection between the framing members should be tested, depending to the design of the connection, Figures from 1 to 3 are examples of typical test configurations, but different configurations may be used. Figures from 4 to 7 are examples of typical test configurations incorporating actual glass supports.
