Foreword
This document (prEN 1096-4:2011) has been prepared by Technical Committee CEN/TC TC 129
“Glass in building”, the secretariat of which is held by NBN.
This document is currently submitted to the CEN Enquiry.
This document has been prepared under a mandate given to CEN by the European Commission and
the European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this
document.
This document supersedes EN 1096-4:2004.
The main changes compared to the previous edition are:
a) The tolerance on emissivity is reduced to +0,01 for coatings with a declared normal emissivity
lower than 0,10;
b) The solar factor, g, is listed within the spectrophotometric characteristics to be declared.
