BS EN 1863-1:2011

What is BS EN 1863-1 - Glass in building - Heat strengthened soda lime silicate glass about?  

BS EN 1863-1 is a European standard that provides definition and description for heat strengthened soda lime silicate glass. BS EN 1863-1 specifies tolerances, flatness, edgework, fragmentation, and physical and mechanical characteristics of monolithic flat heat strengthened soda lime silicate glass of nominal thicknesses from 3 mm to 12 mm for use in buildings. 

Other requirements, not specified in BS EN 1863-1, can apply to heat strengthened soda lime silicate glass, which is incorporated into assemblies, e.g., laminated glass or insulating glass units, or undergo additional treatment, e.g., coating. The additional requirements are specified in the appropriate product standard. Heat strengthened soda lime silicate glass, in this case, does not lose its mechanical or thermal characteristics. 

Note: BS EN 1863-1 does not cover glass sandblasted after toughening. 

Who is BS EN 1863-1 - Glass in building - Heat strengthened soda lime silicate glass for? 

BS EN 1863-1 on glass in building - heat strengthened soda lime silicate glass is useful for: 

• Glass in building manufacturers 
• Silicate glass manufacturers 
• Quality control personnel 
• Designers  
• Construction industries 
• Building safety and control bodies   
• Installers 
• Safety regulatory bodies 

Why should you use BS EN 1863-1 - Glass in building - Heat strengthened soda lime silicate glass?  

Soda lime glass is susceptible to shock and does not handle extreme changes in heat. Untreated soda-lime glass is far more likely than the others to break on your building. It is also more susceptible to breaking from thermal shock (sudden or extreme changes in temperature), therefore BS EN 1863-1 specifies requirements, definition, and description of heat strengthened soda lime silicate glass in buildings. 

As a user of BS EN 1863-1, you can be ensured of the requirements and testing methods, tolerances, flatness, edgework, fragmentation, and physical and mechanical characteristics of monolithic flat heat strengthened soda lime silicate glass. With obedience and compliance to BS EN 1863-1, you can efficiently manufacture heat strengthened soda lime silicate glass. BS EN 1863-1 helps you to build consumer trust and confidence in the product. With BS EN 1863-1 you can be ensured that the products consistently meet and exceed quality assurance targets. 

BS EN 1863-1 specifies the requirements, definition, and description of heat strengthened soda lime silicate glass in buildings, by using BS EN 1863-1 you can increase the efficiency of your organization. 

What is changed since the last update?
