标准编号：ISO 7274:1981

中文名称：锻铝和铝合金.冷拔圆棒材.形状和尺寸公差（直径的负公差）

英文名称：Wrought aluminium and aluminium alloys — Drawn round bars — Tolerances on shape and dimensions (All minus tolerances on diameter)

发布日期：1981-09

标准范围

公差适用于直径在1毫米至65毫米（含65毫米）范围内的拉制圆钢。直径公差均为负公差。直径和允许圆度公差见表1，固定长度公差见表2。还规定了直线度。

The tolerances apply to drawn round bars having diameters in the range from 1 up to and including 65 mm. The tolerances on diameter are all minus tolerances. Tolerances on diameter and permissible circularity are given in table 1, tolerances on fixed lengths are given in table 2. The straightness is also specified.
