BS EN 14321-2:2005 – Glass in building — Thermally toughened alkaline earth silicate safety glass — Part 2: Evaluation of conformity/Product standard

4.3.2.2 Safety in the case of fire – Resistance to fire
Fire resistance shall be determined and classified in accordance with EN 1 3501 -2.
Note EN 357 may be used as a classification reference specific to fire resistant glazed elements.
4.3.2.3 Safety in the case of fire – Reaction to fire
Reaction to fire shall be determined and classified in accordance with EN 1 3501 -1 .
Thermally toughened alkaline earth silicate safety glass products are products/materials that do not require to be tested for reaction to fire (e.g. Products/materials of Classes A1 according to Commission Decision 96/603/EC, as amended 2000/605/EC ).
4.3.2.4 Safety in the case of fire – External fire behaviour
Where the manufacturer wishes to declare external fire performance (e.g. when subject to regulatory requirements), the product shall be tested and classified in accordance with prEN 1 3501 -5.
Note Compliance with this requirement is not possible until a version of prEN 1 3501 -5 later than 2002 becomes available.
4.3.2.5 Safety in use – Bullet resistance: shatter properties and resistance to attack Bullet resistance shall be determined and classified in accordance with EN 1 063.
4.3.2.6 Safety in use – Explosion resistance: impact behaviour and resistance to impact
Explosion resistance shall be determined and classified in accordance with EN 1 3541 .
4.3.2.7 Safety in use – Burglar resistance: shatter properties and resistance to attack Burglar resistance shall be determined and classified in accordance with EN 356.
4.3.2.8 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 1 2600.
4.3.2.9 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 is given in EN 1 4321-1 and shall be ensured by compliance with this document.
4.3.2.10 Safety in use – Mechanical resistance: Resistance against wind, snow, permanent load and/or imposed loads of the glass unit
The mechanical strength of thermally toughened alkaline earth silicate safety glass is a characteristic value that is given in EN 1 4321 -1 and shall be ensured by compliance with this document.
As long as on the concerned construction or building site no part of prEN 1 3474 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 thermally toughened alkaline earth silicate safety glass shall conform to the ordered thickness.
