ISO 3089:2005参考ISO 230-1，规定了具有两个以上钳口的机床用自动定心手动卡盘的几何试验和相应公差。 这种类型的卡盘有被称为“一体式硬卡盘”的卡盘，相对较大的行程允许快速适应各种尺寸的工件，而无需拆卸。 ISO 3089:2005仅涉及卡盘旋转精度的检查、工件的矫直和定心。它不适用于其他动态量，例如平衡测量或握力测量。

ISO 3089:2005 specifies, with reference to ISO 230-1, the geometric tests and corresponding tolerances for self-centring, manually-operated chucks for machine tools with more than two jaws. This type of chuck has jaws known as "one-piece hard jaws", the relatively large stroke of which allows quick adaptation to the most varied sizes of workpieces without dismounting. ISO 3089:2005 deals only with the inspections of rotational accuracy of the chuck, the straightening and the centring of workpieces. It is not applicable to other dynamic quantities, such as measurement of counterbalancing or measurements gripping powers.
