What is BS EN 14321-1 – Thermally toughened alkaline earth silicate safety glass about?
BS EN 14321 is a European Standard that discusses the use of glass in buildings.
BS EN 14321-1 ispecifies tolerances, flatness, edgework, fragmentation and physical and mechanical characteristics of monolithic flat thermally toughened alkaline earth silicate safety glass. These are used in buildings.
Thermally toughened alkaline earth silicate safety glass, in this case, does not lose its mechanical or thermal characteristics.
Note 1: CEN/TC129/WG8 is producing standards for the determination of the design strength of glass and is preparing a design method.
Note 2: Information on curved thermally toughened alkaline earth silicate safety glass is given in Annex A, but this product does not form part of this European Standard.
Note 3: Other requirements, not specified in BS EN 14321-1, can apply to thermally toughened alkaline earth silicate safety glass which is incorporated into assemblies, e.g. laminated glass or insulating units, or undergo additional treatment, e.g. coating.
Who is BS EN 14321-1- Thermally toughened alkaline earth silicate safety glass for?
BS EN 14321-1 on thermally toughened alkaline earth silicate safety glass is useful for:
- Manufacturers of alkaline earth silicate safety glass products
- The glass manufacturing industry
- The construction industry
- Building developers/planners
- Architects
- Quality control, testing and inspection authorities
- Regulatory bodies
Why should you use BS EN 14321-1 - Thermally toughened alkaline earth silicate safety glass?
Thermally toughened alkaline earth silicate safety glass has a safer breakage behaviour when compared with annealed glass.
BS EN 14321-1 walks you through the fracture characteristics, dimensions and tolerances, appropriate edge work, holes, notches and cut-out for alkaline earth silicate safety glass.
Physical characteristics with regards to permissible optical distortion, mechanical and thermal durability is also covered.
BS EN 14321-1 also provides guidance on the fragmentation test that determines whether the glass breaks in the manner prescribed for a thermally toughened alkaline earth silicate safety glass.
If you are a manufacturer of thermally toughened alkaline earth silicate safety glass, compliance with BS EN 14321-1 can demonstrate the performance of your products to ensure they are fit for purpose.
