IsO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

ISO 3442-1 was prepared by Technical Committee ISO/TC 39, Machine tools, Subcommittee SC 8, Work holding spindles and chucks. Together with ISO 3442-2 and ISO 3442-3, this first edition of IsO 3442-1 cancels and replaces ISO 3442:1991 and ISO 9401:1991.

Iso 3442 consists of the following parts, under the general title Machine tools - Dimensions and geometric tests for self-centring chucks with two-piece jaws: Part 1: Manually operated chucks with tongue and groove type jaws Part 2:Power-operated chucks with tongue and groove type ja
