WP.29 Working Parties and Informal Working Groups
Informal Working Groups are authorized by the World Forum and/or the GRs to research and develop new technical procedures and requirements. These groups enable technical experts from government agencies and NGOs as well as independent experts and specialists from other organizations (laboratories, universities, research institutions, etc.) to contribute towards the development of regulatory proposals for consideration by the Forum.
