The furnace is a 90" horizontal oscillating oven. It tempers flat glass up to 90" × 144". Every tempered lite leaves with a permanent temper mark and meets the standard that applies to the part.

Standards we temper to:

**Architectural glazing**

- **ANSI Z97.1-2015 Class A**: the higher impact classification, tested at a 48-inch drop (400 ft-lb)

- **16 CFR 1201 Category II**: the CPSC safety glazing standard. Category II is the equivalent of ANSI Class A

**Automotive glazing**

- **ANSI/SAE Z26.1-1996**: American National Standard for safety glazing materials for motor vehicles

- **FMVSS 205**: Federal motor vehicle safety standard for glazing materials

- **DOT 2050**: our glazing manufacturer code, printed in the mark alongside the AS-2 / AS-3 designation

Category II / Class A is the higher of the two impact classifications, and it is the one the code requires for the openings where someone is most likely to fall into the glass: shower doors and tub enclosures, sliding patio doors, and doors with glazing over 9 square feet. We certify to it, so we can supply those locations.

We run low-distortion cycles for display and furniture work where reflection quality matters. Tell us the application and we'll set the cycle to match.
