标准范围

ISO 5855的本部分规定了航空航天结构中使用的MJ螺纹的一般要求。它确定了这类螺纹的基本三角形轮廓，并给出了指定直径和长度的系统音高组合。对于所有直径为1.6 mm至300 mm的管道，其以表格的形式提供基本尺寸和尺寸直径和节距组合选择的公差。它还提供了计算表中未给出的任何直径和节距组合的尺寸和公差，包括带有直径超过300毫米。公称直径为1.6 mm至39 mm的螺栓和螺母的极限尺寸，见ISO 5855-2.对于极限尺寸流体系统配件，见ISO 5855-3。

This part of ISO 5855 specifies the general requirements for MJ threads used in aerospace construction.It determines the basic triangular profile for this type of thread and gives a system for designating the diameter andpitch combinations. For all diameters 1,6 mm to 300 mm, it offers in the form of tables the basic dimensions andtolerances for a selection of diameter and pitch combinations. It also provides the method of calculation for thedimensions and tolerances for any diameter and pitch combination not given in the tables, including threads with adiameter in excess of 300 mm.For limit dimensions for bolts and nuts of nominal diameter 1,6 mm to 39 mm, see ISO 5855-2. For limit dimensions forfittings for fluid systems, see ISO 5855-3.
