69. The Chair of the IWG on VIAQ reported on the ongoing activities on collection of information and review of existing standards to develop recommendations to harmonize test procedures of interior air emissions generated from interior materials (GRPE-72-21). He explained some issues on which the group could reach an agreement such as test measurement modes to be considered (ambient, parking and driving modes) and substances to be measured (e.g. specific Volatile Organic Compounds). He listed some open issues on test procedure parameters which were still under discussion.

70. GRPE acknowledged the progress made by the IWG on VIAQ and noted the request for a meeting room for half a day during the GRPE week in June 2016.
