4. 2. TF1 working progress The 4th EVS meeting TF1 was set up.
TF1 discussed the requirements and test procedures of insulation resistance proposed by FAW(China).
The 6th EVS meeting
EVS IWG asked TF1 draft a proposed text for inclusion in the draft GTR.
The 7th EVS meeting
TF1 proposed draft to the EVS IWG.
The 8th EVS meeting
TF1 experts reached an agreement about the draft except one open issue—detailed parameter of the flooding test procedure.
The 9th EVS meeting
The flooding parameters were discussed (EVS-08-17e) but without reaching any agreement.
REESS immersion test at pack level which was agreed to be discussed TF1.

5. 2. TF1 working progress The 10th EVS meeting
Conclusion
All contract member’s agree with including water exposure test in phase 1 and the GTR draft
presented by china in principal.
Open issues
Whether the vehicle equipped with isolation monitoring systems need to be tested.
（USA and EU’s points are all EVs should do the water exposure test ; Japan and China’s points are the vehicle equipped with isolation monitoring systems need not to be tested）
Action
TF1 will ask for feedbacks from all members about open issues:
China and Japan will provide the rationale to explain EV equipped with isolation monitoring systems need not to be tested, and provide the detailed requirements draft and the function reliability verifying procedure of isolation monitoring systems.
Collect rationale to explain why all EVs should do the water exposure test.
TF1 will provide the proposal to EVS 11th meeting.

6. 2. TF1 working progress Progress after EVS 10th Meeting
March 24th , Tianjin China
China and Japan made F2F meeting discussing the detailed requirements draft and the function reliability verifying procedure of isolation monitoring systems and provided the proposal of China and Japan to TF1 members.
May 26th , Beijing China.
China and Japan made F2F meeting discussing the draft proposal of TF1 and reach an agreement between the Chinese government and Japan and provided the draft proposal to the EVS secretary.

7. 3. Summary
TF1 agree with including water exposure test in phase 1 and the GTR draft presented by china in principal.
Keep on discussing whether the vehicle equipped with isolation monitoring systems need to be tested.
Closed
TF1 working Scope and objective
Identifying potential risk of electric shock caused by water, drafting the requirements for the GTR.
Washing and flooding are the representative examples of severe conditions in normal vehicle operation.
Isolation resistance value needs to be maintained in a range to prevent electric shock. When double isolation resistance failure occurs, it is possible that a person gets an electric shock.
Open
Whether the vehicle equipped with isolation monitoring systems need to be tested.
