Bertrand LOMBARD convened the 28th meeting of WG 2 Statistics of ISO/TC 34/SC 9 "Food products-Microbiology", held at Campden BRI, Campden UK, on 18-19 October. The main topic on the agenda was the revision of ISO/TS 19036, dealing with measurement uncertainty for quantitative determinations. This project is led by Basi JARVIS (Project Leader), Keith JEWEL and Paul IN'T VELD (co-Project Leaders). More precisely, WG 2 has given a follow-up to the ISO/CEN vote on ISO/DIS 19036. This vote had a very positive outcome with 100% approvals but with many comments.
