注:1.表中的理论质量是按密度为
2.表内尺寸一栏,对于圆钢丝表示直径;对于方钢丝表示边长;对于六角钢丝表示对边距离,以下各表相同。
3.表中的钢丝直径系列采用R20优先数系,其中“*”符号系列补充的R40优先数系中的优先数系。
4.直条钢丝的通常长度为2000
5.直条钢丝按定尺、倍尺交货时,其长度允许偏差为+
(2)允许偏差见表7-2~表7-4。

注:1.钢丝尺寸的偏差应符合表7_2或表7-3的规定,其具体要求应在相应的技术条件或合同中注明。
2.中间尺寸钢丝的尺寸允许偏差按相邻较大规格钢丝的规定。
3.圆钢丝的圆度应不大于直径公差之半。经供需双方协议,可以供应其他圆度的钢丝。
4.方钢丝的对角线差不得大于相应级别边长公差的0.7倍。
5.直条方钢丝、六角钢丝不得有明显扭转。
6.直条钢丝每米弯曲度不得大于
7.钢丝盘应规整,且由一根钢丝组成,当解开捆扎线时不得散乱或呈“∞”字形。
