What is EN ISO 12543-2:2012?

EN ISO 12543-2:2012 is an international standard that provides specifications for glass in building - laminated glass and laminated safety glass. It is part of the EN ISO 14449 series, which covers all aspects of glass used in buildings. This particular standard focuses on laminated glass, which is widely used in architectural applications due to its safety and security features.

The Composition of Laminated Glass

Laminated glass consists of two or more glass sheets bonded together using one or multiple interlayers. The interlayers are typically made of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA), which provide strength and adhesion between the glass layers.

EN ISO 12543-2:2012 specifies the requirements for the composition, dimension, and tolerances of laminated glass. It ensures that the interlayers meet specific performance criteria, such as adhesion strength, resistance to water penetration, and durability over time.

Safety and Security Features

One of the primary benefits of laminated glass is its enhanced safety and security features. When laminated glass breaks, the interlayer holds the shattered glass pieces together, preventing them from scattering and causing harm. This makes it an ideal choice for applications where human impact safety is crucial, such as windows, doors, skylights, and balustrades.

Furthermore, the use of different interlayer materials can enhance additional properties, including sound insulation, UV protection, and fire resistance. Laminated glass can be customized to meet specific requirements, making it a versatile option for various architectural designs.

Testing and Certification

EN ISO 12543-2:2012 outlines the testing methods and criteria for laminated glass, ensuring its compliance with safety standards. The standard covers various tests, including adhesion strength, impact resistance, and fragmentation. These tests evaluate the performance of laminated glass under different conditions, such as extreme temperatures and mechanical stress.

Manufacturers must adhere to the requirements specified in EN ISO 12543-2:2012 to obtain certification for their laminated glass products. This certification provides customers with confidence in the product's quality, safety, and durability.

In conclusion, EN ISO 12543-2:2012 is an essential international standard that specifies the composition, properties, and testing methods for laminated glass used in buildings. Its focus on safety, security, and performance ensures that laminated glass meets industry standards and provides the necessary protection in architectural applications.
