Glaston has launched Online Stress Calculation (OSC™), a new technology designed to provide continuous verification of tempered glass quality directly within the tempering process. The solution addresses long-standing limitations associated with traditional fragmentation testing and conventional stress measurement methods.

Tempered glass safety depends on achieving the correct stress profile. When broken, properly tempered glass fragments into small, less hazardous pieces, significantly reducing the risk of serious injury. However, verifying tempering quality has traditionally relied on destructive break tests, which can only be performed on selected samples and are not suitable for every processed glass unit.

OSC™ offers an alternative by calculating surface stress, middle-pane tension, and estimated fragmentation performance for every piece of glass produced. Integrated directly into the tempering line operating system, the technology continuously analyzes critical process parameters during production and generates real-time tempering data without damaging the glass.

The system automatically alerts operators whenever measured values fall outside predefined tolerances, enabling immediate corrective action. In addition, processors can establish their own stress-level requirements and ensure these standards are consistently applied across all production batches.

According to Glaston, OSC™ allows manufacturers to document the tempering level of each individual glass unit, providing valuable quality assurance data for customers and project stakeholders.
