Geometrical Product Specifications
ISO TC 213: "Dimensional and geometrical product specifications and verification" is the Technical Committee covering Geometrical Product Specifications (GPS) within ISO. I am the convenor of WG 18: "Geometrical Tolerancing". I used to be the convenor of WG1: "Roundness, Straightness, Cylindricity and Flatness" and AG 11: "Underlying Concepts", but they have both completed their tasks and have been closed..
You can visit the ISO TC 213 homepage, which contains all the public information on the work of this technical committee.
