Quality Standards 

MWGF follows ASTM Standards as a base line.

Based on machine capabilities and our own quality standards. 

These guidelines allow for certain defects and variations in fabricated and non-fabricated products. 

  • The ASTM (American Society for Testing & Materials) Set standards for a variety of industries. 

    • The ASTM's glass industry standards provide guidelines for allowable defects, quality, and how to visually inspect glass for: ​

      • Flat Glass​

      • Heat-strengthened and Tempered glass

      • Laminated Glass

      • Insulated Glass

  • We use Quality 3 standards when reviewing glass.
