ISUZU ISA-E-005A

JAPANESE/ENGLISH VERSION

この規格は、金属部品の削り加工（切削屑を生じる加工）により得られる長さ寸法及び角度寸法において、図面中に個々に公差が指示されていない寸法に適用する公差（以下普通公差という。）につい て適用する。ただし、別にいすゞ規格に定められているものを除く。 例 ： ねじ精度（ISA-M-002Aによる）また、寸法を決定する一方の面が削り加工によらない場合には、互いの普通公差のうち大きい方を適 用する。

This standard covers the tolerance applying to the linear andangular dimensions for the cutting work, to which their tolerancesare not attached to individual dimensions but shown collectively ondrawings (hereinafter called general tolerance). The cutting workmeans the machining process in which cutting tools produce chips.However, this standard does not cover the tolerances separatelyspecified in Isuzu’s standards, for example, that for threadaccuracy which is covered by ISA-M-002A. And, if a dimension isdetermined between two surfaces; one surface is machined in cuttingwork but the other is processed otherwise, the coarser of thegeneral tolerances applying to the surfaces shall be used with thedimension.
