ANSI H35.2-2024, Dimensional Tolerances for Aluminum Mill Products, is the 2024 revision of H35.2-2017 and gives the permissible variations from specified dimensions for aluminum mill products in U.S. customary units. It covers flat rolled products (sheet, plate and foil), rod, bar and wire, extruded shapes, and tube, with the tolerance tables used to check thickness, width, length, diameter, straightness, flatness, camber, twist, squareness and cut length. Cross-sectional tolerances for extruded profiles, including wall thickness, corner and fillet radii and angularity, are also specified. Because these limits are the basis on which mill products are ordered, inspected and accepted, the standard is used daily by producers, distributors, fabricators and inspectors, and is referenced throughout Aluminum Standards and Data.
