Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more tha

The tolerance
18、s included in this Standard were developed by the Technical Committee of The Aluminum Association. They are broadly accepted both within the aluminum industry itself and by users of the metal. They are the basis of the dimensional tolerances specified in U.S. government, technical society, and other
19、 specifications for aluminum products. They represent the maximum deviation from specified dimensions that may be expected in any individual piece. For most pieces the deviation from specified dimensions will be less than the tolerance shown. Work on the tolerances began in The Aluminum Association
20、in 1949, five years before its Technical Committee was established. In that year a special committee was appointed by the Associations Extruded Products Division to develop drafting standards for these products. One of the committees assignments was to develop standard tolerances for aluminum extrus
21、ions. The committee completed its work later in 1949, and the Association issued the first edition of its Drafting Standards for Extruded and Tubular Products, including the tolerances, in October of that year. By 1954, the Associations technical activities had grown to the point that a standing Tec
22、hnical Committee was needed. One of the first jobs undertaken by this committee was the compilation of mechanical property data for commonly used aluminum alloys and dimensional tolerances for other aluminum mill products. This work was completed later in 1954, and the resulting data were published
23、in the first edition of the Associations “Standards for Aluminum Mill Products” in June 1955. Successive editions of the “Standards for Aluminum Mill Products” have been revised to include new data and to keep the manual abreast of industry advances. In 1968 the title was changed to “Aluminum Standa
24、rds and Data” to reflect the adoption of a revised format. Many refinements have been made in the tolerances as experience was gained in their use. In addition, tolerances have been developed for products not covered initially, and the data have been extended to embrace the larger sizes now being pr
