本SAE航空航天标准（AS）为解释和澄清与流体系统联轴器、卡套管接头和软管端部的制造和检查有关的工程图纸要求提供了一般信息。由于在图纸表面上定义零件的每一个细节都是不切实际的，因此本标准描述了一般机械加工特征的尺寸标注和其他未定义公差的解释，这些公差属于“良好车间实践”的标题。本标准是对ASME Y14.5M-1994的补充，并解释ASME Y14.5M-1994未提及的图纸术语或实践。除非本标准另有规定，否则应适用ASME Y14.5M-1994中包含的图纸解释。

This SAE Aerospace Standard (AS) provides general information for the interpretation and clarification of engineering drawing requirements relating to the manufacture and inspection of fluid system couplings, tube fittings, and hose ends. Because it is impractical to define every minute detail of the part on the face of the drawing, this standard describes interpretations of dimensioning of general machining features and otherwise undefined tolerances that fall under the heading of “good shop practice.” This standard is supplemental to ASME Y14.5M-1994 and explains, defines, and interprets drawing terms or practices that are not addressed by ASME Y14.5M-1994. Unless otherwise specified in this standard, drawing interpretations contained in ASME Y14.5M-1994 shall apply.
