133. The representative of United Kingdom, on behalf of the chair of the IWG on Phase 2 of UN GTR No. 7 on head restraints, mentioned that at the March 2017 session of WP29, it had been acknowledged that the GTR7 IWG had not been able to establish injury criteria directly from post mortem subjects testing but that they had developed some understanding based on empirical data. He added that following that meeting, the expert from the United States of America agreed to explore their capacity to provide further post mortem subjects data. He added that it seems unlikely that the United States of America could complete any related work by the end of 2017. Accordingly, AC.3 at its previous session agreed to extend the time mandate for the IWG to allow it to resolve their work using an empirical approach if the data could not be obtained.

134. The representative of United Kingdom informed AC.3 that the IWG Chair had met with the manufacturer of BioRID who confirmed its willingness to provide additional information to support a BioRID certification requirement and that more detail would be provided before the summer break. He finally informed AC.3 that at the May 2017 session of GRSP, experts were advised of the intention to restart the IWG and, following the intended discussion with the manufacturer, the Chair of the IWG would establish a plan to deliver a proposal to the spring 2018 meeting of GRSP.
