(This foreword is not a part of American National Standard AWI SMA 0643 – Wood Stair, Handrail, and Guard Systems)
The ANSI/AWI 0641 – Architectural Wood Casework Standard is intended to provide standards and tolerances for the quality and fit of Architectural Wood Casework and related interior finishes.
The ANSI/AWI SMA 0643 Wood Stair, Handrail, and Guard Systems Standard is intended to provide comprehensive guidelines for wood stairs, handrail, and guard systems.
This standard encompasses a variety of wood stair, handrail, and guard systems and establishes structural and aesthetic tolerances, ensuring that the final product is of the utmost quality with regards to visual appeal and structural integrity.
This standard is intended for use by individuals and organizations from all aspects of the wood stair industry, including architects, design professionals, stairbuilders, manufacturer/suppliers, contractors, installers, and end users. Individuals within the industry will use this standard to maintain a high degree of control over the aesthetic quality and the structural integrity of their work, ensuring that potential differentiations in the workmanship and implementation of projects are made uniform.
This standard is meant to function in harmony with all current AWI Standards and is not meant to stand alone.
Effective August 15, 2021, this standard succeeds, replaces, and supplants Section 7 of the Architectural Woodwork Standards, Ed. 2 (2014) as the most current version of the AWI Standard for Wood Stair, Handrail, and Guard Systems.
