CEN/TS 19100-1 gives basic design rules for mechanically supported glass components. This document is concerned with the requirements for resistance, serviceability, fracture characteristics and glass component failure consequences in relation to human safety, robustness, redundancy and durability of glass structures. (2) This document covers the basis of design, materials, durability and structural design. (3) This document also covers construction rules for the structural design of glass components. 1.2 Assumptions (1) The assumptions of EN 1990 apply to CEN/TS 19100-1. (2) This document is intended to be used in conjunction with EN 1990, EN 1991 (all parts), EN 1993-1-1, EN 1995-1-1, EN 1998-1, EN 1999-1-1 and EN 12488.
