AITC provides Quality Marks and Certificates of Conformance to licensed glued laminated timber material manufacturers. Only AITC licensed glued laminated timber producers are permitted to use these Quality Marks and Certificates to identify products conforming to ANSI/AITC A190.1.

AITC’s Quality Control and Inspection Program for structural glued laminated timber works to:

• Standardize production, testing, inspection, identification, and certification to structural glued laminated timber.
• Improve economics through wider utilization of standards.
• Ensure the manufacture of reliable products.

The Program consists of three basic elements:

• Licensing of qualified glued laminated timber manufacturers whose personnel, procedures and facility comply with the requirement of the American National Standard for Wood Products – Structural Glued Laminated Timber – ANSI/AITC A190.1.
• Continuous maintenance of the qualified manufacturer’s quality control system in accordance with ANSI/AITC A190.1.
• Periodic inspection and verification, by the AITC Inspection Bureau, of the licensed laminator’s quality control system, procedures and production.
