标准摘要
[中文适用范围]： 本 SAE 标准规定了影响配对法兰和配合零件之间互换性的标称尺寸和公差。本文件涵盖的法兰被指定为 A 型和 S 型。A 型法兰相当于 ISO 7646 中的 A 型法兰。S 型法兰相当于 ISO 7647 中的 S 型法兰。A 型是外部（外螺纹）先导结构， S 型是内部（内）先导结构。这些法兰不可互换。未指定的尺寸由组件制造商自行决定。 [外文原描述]： This SAE Standard specifies the nominal dimensions and tolerances which affect the interchangeability between companion flanges and mating parts. The flanges covered by this document are designated type A and type S.The type A flanges are equivalent to type A ISO 7646. The type S flanges are equivalent to the type S ISO 7647. Type A is an external (male) pilot construction and type S is an internal (female) pilot construction. These flanges are not interchangeable. Dimensions not specified are left to the discretion of the component manufacturer.Cross Reference: ISO1101,ISO286
