EN 14449:2005 – Glass in building – Laminated glass and laminated safety glass – Evaluation of conformity/Product standard

4.3.2.4 Safety in use – Bullet resistance: shatter properties and resistance to attack Bullet resistance shall be determined and classified in accordance with EN 1063.
4.3.2.5 Safety in use – Explosion resistance: impact behaviour and resistance to impact Explosion resistance shall be determined and classified in accordance with EN 13541.
4.3.2.6 Safety in use – Burglar resistance: shatter properties and resistance to attack Burglar resistance shall be determined and classified in accordance with EN 356.
4.3.2.7 Safety in use – Pendulum body impact resistance: shatter properties (safe breakablity) and resistance to impact
Pendulum body impact resistance shall be determined and classified in accordance with EN 12600.
NOTE Laminated glass conforming with EN ISO 14543-3 (No EN 12600 classification) will be declared NPD.
4.3.2.8 Safety in use – Mechanical resistance: Resistance against sudden temperature changes and temperature differentials
The resistance against sudden temperature changes and temperature differentials is a generally accepted value. That value is given in the standards (see Table 1) for the appropriate glass substrate.
4.3.2.9 Safety in use – Mechanical resistance: Resistance against wind, snow, permanent load and/or imposed loads of the glass unit The ordered assemblies of laminated glass or laminated safety glass (thickness and types of glass components or plastic glazing sheet materials – interlayers) shall ensure the resistance against wind,snow, permanent load, and other mechanical, (quasi-) static action, which shall be checked in accordance with design standards 2 .
As long as on the concerned construction or building site no part of the design standards is applicable for the design then the current method of determining mechanical resistance in the country of destination shall be applied.
The manufactured or supplied thickness of laminated glass or laminated safety glass shall conform to the ordered thickness.
4.3.2.10 Protection against noise – Direct airborne sound reduction The sound reduction indexes shall be determined in accordance with EN 12758.
4.3.2.11 Energy conservation and heat retention – Thermal properties The thermal transmittance value (U-value) shall be determined by calculation in accordance with EN 673 with:
