	Testing Services   Glass Fab's Quality System presently operates under MIL-I-45208A guidelines. In an effort to comply to the intent of the ISO-9002 quality system, we are constantly improving our systems. It is our time tested familiarity and understanding of the materials, processes, and specifications that allow us to offer our customers unsurpassed quality and service. This commitment to Quality is demonstrated by Glass Fab's approval as a preferred Vendor by several major Aerospace companies including Honeywell, Thales (UK), and Advanced Silicon Materials. The stringent requirements of these companies have been incorporated into our general manufacturing and quality procedures.   Below is a partial list of our inspection equipment. All of our inspection equipment is routinely calibrated and certified to insure accuracy and precision per MIL-STD-45662.
