Product Code:SAE MAM2205
Title:Tolerances, Metric, Aluminum Alloy and Magnesium Alloy Extrusions (Cancelled Apr 1987, Superseded by ANSI H35.2(M))
Issuing Committee:Ams D Nonferrous Alloys Committee
Scope: This specification covers established metric manufacturing tolerances applicable to aluminum alloy and magnesium alloy extruded bar, rod, wire, shapes, and tubing ordered to metric dimensions. Tolerances greater than standard may be necessary for some shapes; tolerances closer than standard may be possible for others. Tolerances shown herein, however, apply unless otherwise agreed upon by purchaser and vendor and apply to all tempers, unless otherwise noted.【英文标准名称】:Measurementmicrophones;part2:primarymethodforpressurecalibrationoflaboratorystandardmicrophonesbythereciprocitytechnique(IEC61094-2:1992);GermanversionEN61094-2:1993
