Proposal to develop an amendment in order to align GTR No. 3 with technical progress, addressing among others: ensuring electromagnetic immunity of ABS-systems, introducing ABS performance requirements for category 3-5 vehicles (three-wheelers), ensuring uniform requirements for equipment such as Electronic Stop Signal System and the means to disable the ABS, if equipped. This amendment aims to harmonize GTR with recent amendments made to UN Regulation No. 78.

Proposal to develop amendments to Part II of GTR No.16:

1. Addition of new definitions (Section 2);
2. Harmonization of the Load Range concept in relationship to Inflation Pressure (Section 2),
3. Alignment of the provisions for tyre marking and physical dimensions of PC tyres with the most recent developments in UN Regulations Nos. 30 and 54 (Sections 3.3 and 3.5),
4. Harmonization of FMVSS 139 requirements relative to UNECE PSI index (Sections 3.14 and 3.15),
5. Deletion of provisions for physical dimensions of LT/C tyres based on FMVSS 139 (Section 3.20) an UN Regulation No. 54 (Section 3.21) and addition of new harmonized provisions for physical dimensions of LT/C tyres (new Section 3.20),
6. Deletion of provisions for high speed test for LT/C tyres based on FMVSS 139 (Section 3.19) and UN Regulation No. 54 (Section 3.16) and addition of new harmonized provisions for high speed test for LT/C tyres (new Section 3.16),
7. Updates of the Annexes 3 and 6 with regard to the most recent developments in UN Regulations Nos. 30 and 54.

Other topics to be discussed within the informal working group for the Phase 2 of development of UN GTR No. 16 include:

1. Consideration of feasibility of harmonization of endurance test for LT/C tyres (Sections 3.16 and 3.17), and
2. Consideration of feasibility of development of provisions for global tyre marking.

Proposal for the Phase 2 development of GTR No. 13, including

1. Further consideration of items in the original authorization (document WP.29/AC.3/17);
2. Potential revision of the scope to address additional vehicle classes;
3. Requirements for material compatibility and hydrogen embrittlement;
4. Requirements for the fueling receptacle;
5. Evaluation of performance-based test for long-term stress rupture proposed in Phase 1 (including assessment of a procedure to evaluate the risk of long-term stress rupture of storage containers made from composite fiber reinforced polymers);
6. Consideration of research results reported after completion of Phase 1 – specifically research related to electrical safety, hydrogen storage systems, and post-crash safety;
7. Consideration of 200 per cent Nominal Working Pressure (NWP) or lower as the minimum burst requirement; and
8. Consider Safety guard system for the case of isolation resistance breakdown.
