WP.29 Working Parties and Informal Working Groups
WP.29 consists of the World Forum and six permanent subsidiary working parties (GR). As warranted, WP.29 authorizes the formation of informal working groups to address specific subjects. This page provides links to pages concerning the Forum, its working parties as well as the past and present informal working groups of experts (and their subgroups). Click on any item for more information about that group.
