Technical committees

From Assistive products to Zinc alloys

Here you’ll find a list of the ISO technical committees in the order in which they were created. The first, TC1, deals with screw threads and was created back in 1947. While, more recently, TC 309 was created to standardize organizational governance.

Clicking on the committee name will give you more specific information, such as who’s the chairman and which ISO member holds the secretariat. You can also consult the program of work to see what meetings are coming up and what standards are in the pipeline.
