This Standard, previously titled hardboard siding, covers requirements and methods of testing for the dimensions, straightness, squareness, physical properties, and surface characteristics of engineered wood siding. In 2010 the industry changed the product name from hardboard siding to Engineered Wood Siding to more accurately describe the product. Definitions of trade terms used and methods of identifying products that comply with the standard are included.
This Standard may be revised or withdrawn at any time.
