scope:
Describes, with reference to ISO 230-1, the geometrical tests and the corresponding permissible deviations of two classes of accuracy for self-centring, manually-operated chucks for machine tools with more than two jaws. This type of chuck jaws known as "on-piece hard jaws", the relatively large stroke of which allows quick adaptation to the most varied sizes of workpieces without dismounting.
