Glass in building -- Glass products for structural sealant glazing -- Part 2: Assembly rules
ISO 28278-2:2010 gives guidelines for the assembly and bonding of glass elements in a frame, window, door or curtain-walling construction, or directly into the building by means of structural bonding of the glass element into or onto the framework or directly into the building.
It gives the assembler information that enables him to organize his work and comply with requirements regarding quality control.
Quality control of the assembly process is of the highest importance. ISO 28278-2:2010 provides the minimum requirements for acceptable quality control of the process of structural sealant glazing (SSG) on a single project. The annexes contained at the end of ISO 28278-2:2010 provide the methods to ensure proper application and documentation for a safe and weatherproof glazing assembly product.
This process is intended to be applicable to most SSG projects. The project testing on metal substrates and glass products will determine proper surface preparation and installation instructions.
These rules do not apply to the adhesion or durability of the paint finishes or glass products. This is not intended to be a durability test requirement for the paint and glass products commonly used in the SSG process.
The structural, weatherproofing and sealant products which are commonly used in structural glazing applications are those based on organosiloxane, "silicone" polymers.
ISO 28278-2:2010 does not preclude the use of other sealant types, where these can demonstrate suitability for service according to ISO 28278-2:2010 and when they are used following the recommendations of the sealant manufacturer.
