Proposal to add checks under the current tests:

• damage to seat attachments
• occupant compartment hazards (e.g., risk of impact by loose objects such as fire extinguisher) and
• post-crash functionality of escape hatches (including force required to open)

Proposal for additional checks following complete vehicle tests:

1. destruction of seats mounts. The break-off and displacement of seats is not covered by the current Regulation, since they are initially located inside the residual space and their displacement is not assessed;
2. injury-causing objects entering the residual space and moving within it (e.g., if a person is hit by a fire extinguisher or other object when the vehicle overturns, it may cause serious or even fatal injuries).

Proposal to clarify the verification procedures after the strength test. The proposal addresses destruction of seat mounts, injury-causing objects entering the residual space and moving within it, and emergency hatches.

Proposal from Russian expert to undertake additional checks in terms of passive safety

Clarifies the verifications after the performance of the strength test.

Proposal to allow additional checks in terms of passive safety on the national level (for example, destruction of seats mounts, injury-causing objects entering the residual space and moving within it, operability of the emergency hatches).

Proposal to allow additional checks on passive safety at the national level when conducting tests of a complete vehicle (such as checking for damage to seat mounts, objects presenting injury risks in the residual space, and operability of hatches).

The Russian Federation considers that additional checks of a complete vehicle during rollover tests should be provided within the framework of UN R66 as an option at the national/regional level and requests guidance on whether such flexibility is permissible.

Proposal to introduce definitions of “escape hatch” and “emergency exit”, a test requirement for these devices, and provisions to ensure that elements that can move and enter the residual space of passengers after the bus overturning are present during testing, including provisions on fire extinguishers.

Proposal to add terms and definitions for “escape hatch” and “emergency exit”.

Proposal for to add the definitions “escape hatch” and “emergency exit”.

Proposal to add the definitions “escape hatch” and “emergency exit”, as well as additional requirements for the safety of living space in the bus cabin.
