10. The expert from the United States of America, on behalf of the co-sponsors (Japan, Republic of Korea, European Union) and the members of the IWG on UN Global Technical Regulation (UN GTR) No. 13 – Phase 2, informed GRSP about the group’s progress. He reported that the last IWG meeting had been held in Brussels from 9 to 11 October 2018, and had been attended by more than sixty representatives from various contracting parties, motor vehicle and container industries, standard organizations and academia. He added that experts had continued discussing major technical items for Phase 2, requirements for heavy vehicles and buses, material compatibility, tank stress rupture, fire test parameters and clarification of existing UN GTR test procedures. The next IWG meeting was scheduled for March 2019. He added that the five Task Forces (TF) had provided their state of progress and issues:

1. TF No.1 – Heavy duty vehicles and buses, had an extended discussion as the fuel system is significantly different than those in light duty vehicles. The requirements needed to be well thought out due to differences in architecture, usage and application. TF had begun monthly web meetings to identify relevant topics and to hold discussions;
2. TF No. 2 – Fuelling receptacle requirements, had planned to submit a draft proposal for fuelling receptacle requirements at the next working group meeting;
3. TF No. 3 – Recommendations for test procedures, was progressing well and should complete its work by the summer of 2019;
4. TF No. 4 – Fire test, was also progressing well and was scheduled to complete its work in 2019;
5. TF No. 5 – Recommendations from ISO TC197, had recommended a technical information proposal for the rationale section.
