注：1.表中的理論質(zhì)量是按密度為7.85g／cm3計算的，對特殊合金鋼絲，在計算理論質(zhì)量時應(yīng)采用相應(yīng)牌號的密度。
2.表內(nèi)尺寸一欄，對于圓鋼絲表示直徑；對于方鋼絲表示邊長；對于六角鋼絲表示對邊距離，以下各表相同。
3.表中的鋼絲直徑系列采用R20優(yōu)先數(shù)系，其中“*”符號系列補充的R40優(yōu)先數(shù)系中的優(yōu)先數(shù)系。
4.直條鋼絲的通常長度為2000-4000mm，允許供應(yīng)長度不小于1500mm的短尺鋼絲，但其質(zhì)量不得超過該批質(zhì)量的15％。
5.直條鋼絲按定尺、倍尺交貨時，其長度允許偏差為+50 mm+0mm。
(2)允許偏差見表7-2～表7_4。
