Quality Standards 

MWGF follows ASTM Standards as a base line, and in fact uses stricter guidelines than those provided by ASTM. 

Based on machine capabilities and our own quality standards. 

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

  • 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

  • Generally, use Quality 3 standards
