Open issues list (Working Paper WLTP-05-04) was presented by Ichikawa, TS. India raised the issue of definition of maximum speed as regional option or R68 application and supported a harmonized definition. Issue is on OIL for HEV and will be discussed again for ICE vehicles. The potential need for validation is indicated for each issue.
The experts who are responsible to develop the proposals for the open issues are indicated in the OIL. To ensure a sufficient pre-discussion of the proposals in advance of the WLTP IWG meetings other relevant experts/parties shall be involved already in the early development process. These stakeholders shall indicate their interest to the responsible expert and WLTP IWG leading team.

General: Presentations on Normalization procedures (Steininger, EC) and on Ambient Temperature Correction Test (ATCT) (Eder, BMW). EC recommended special meeting of RLD experts to discuss normalization approach in 1st Quarter 2014. ACEA will provide first validation data on the family characteristics until end of January.
Chair encouraged Contracting Parties and other stakeholders to show their interest to participate in the validation program for the ATCT procedure.
Chair requested Contracting Parties to give a feedback on the proposed normalization procedures and the interest to (partly) harmonize such procedures in the gtr. Feedback of CPs to WLTP Chair is requested until 14.2.2014.
