GPS: Geometrical Product Specifications
ISO TC 213: "Dimensional and geometrical product specifications and verification" is the Technical Committee covering Geometrical Product Specifications (GPS) within ISO, the International Orgainzation for Standardization.
I have been the chairman of ISO TC 213 since 2008. I am the convenor of WG 4: "Uncertainty". I used to be the convenor of WG 18: "Geometrical Tolerancing", but I gave up that post when I became chairman. I was also 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.
