What is BS EN 16613 - Laminated glass and laminated safety glass about?

BS EN 16613 is a European standard on glass in building that covers determination of interlayer viscoelastic properties of laminated glass and laminated safety glass.

BS EN 16613 specifies a test method for determining the mechanical viscoelastic properties of interlayer materials. The interlayers under examination are those used in the production of laminated glass and/or laminated safety glass. The interlayer viscoelastic properties are needed in order to determine the load resistance of laminated glass.

Note: Informative Annex D explains the background to the determination of families relating to a specific interlayer shear transfer coefficient.

Who is BS EN 16613 - Laminated glass and laminated safety glass for?

BS EN 16613 on laminated glass and laminated safety glass is useful for:

Laminated glass and laminated safety glass manufacturers
Mechanical engineers

Why should you use BS EN 16613 - Laminated glass and laminated safety glass?

Laminated glass (LG) is a type of safety glass that holds together when shattered. In the event of breaking, it is held in place by a thin polymer interlayer, typically of polyvinyl butyral (PVB), ethylene-vinyl acetate (EVA), lonoplast polymers, cast in place (CIP) liquid resin, or thermoplastic polyurethane (TPU), between its two or more layers of glass.

In materials science and continuum mechanics, viscoelasticity is the property of materials that exhibit both viscous and elastic characteristics when undergoing deformation.

The purpose of BS EN 16613 is to provide the viscoelastic properties of interlayer materials in order that calculations for the load resistance of laminated glass panes can be undertaken.

In addition, BS EN 16613 includes a procedure for categorizing the interlayer materials into families, which can be associated with shear transfer coefficients which are used in a simplified calculation method according to EN 16612.

BS EN 16613 can help safeguard your organization by increasing your knowledge about viscous and elastic characteristics of materials when undergoing deformation.
