This document is currently submitted to the CEN Enquiry.
This document will supersede EN 1748-2-2:2004.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports basic work requirements of EU Regulation 305/2011.
For relationship with EU Regulation/Directive(s), see informative Annex ZA which is an integral part of
this document.
The main changes compared to the previous edition are the following:
a) The standard has been revised to fulfil the requirements of the Regulation (EU) No 305/2011
(Construction Product Regulation), modified by Regulations (EU) No 157/2014, (EU) No 568/2014
and (EU) No 574/2014.
b) The solar factor, g, is listed within the spectrophotometric characteristics to be declared in the
Declaration of Performances (DoP).
c) The durability/conformity assessment is listed within the characteristics to be declared in the DoP.
d) The mechanical resistance shall be given in the DoP by the characteristic bending strength of the
glass.
EN 1748 is currently composed with the following parts:
— EN 1748-1-1, Glass in building — Special basic products —Borosilicate glasses — Part 1-1: Definition
and general physical and mechanical properties;
