Quality Control - Testing

Quality testing booth in the cold end. Float and coated glass samples are cut and submitted for rigorous quality control testing.

Quality testing of the coated glass is conducted by taking samples from the line every 30 minutes for examination using a range of instrumental methods. 

Each of the samples taken from across the ribbon are tested for:

Transmission
Clarity
Reflective colour
Electrical conductivity is used to measure the performance of the coating
In addition all float glass is tested to ensure excellent optical, physical and performance characteristics
All results are fed back online to the glassmaking and coating operators so any adjustments to the process can be made to ensure the strictest quality control targets are met.
