5.1.   

General requirements



5.1.1.   

The cab of the vehicle shall be so designed and so attached to the vehicle as to eliminate to the greatest possible extent the risk of injury to the occupants in the event of an accident.



5.1.2.   
Vehicles of categories N1 and vehicles of categories N2 with a gross vehicle mass not exceeding 7,5 t shall be subjected to the tests A and C, as described in Annex 3, paragraphs 5 and 7.
However a vehicle type which meets the frontal impact requirements of Regulation No 12 or Regulation No 33 or Regulation No 94, and vehicles of category N1, derived from M1 approved to Regulation No 94, may be considered to have satisfied the requirements on frontal impact (test A).
Test C shall only be conducted on vehicles which have a separate cab.


5.1.3.   
Vehicles of categories N3 and vehicles of categories N2 with a gross vehicle mass exceeding 7,5 t shall be subjected to the tests A, B, and C, as described in Annex 3, paragraphs 5, 6, and 7.
Test C shall only be conducted on vehicles which have a separate cab.


5.1.4.   

Test A (frontal impact) shall only be conducted on cab-over-engine vehicles.



5.1.5.   

One, two or three cabs, at the manufacturer’s choice, may be used for the purpose of demonstrating compliance with paragraphs 5.1.2 or 5.1.3 above. However both phases in test C, if applicable, shall be conducted on the same cab.



5.1.6.   

None of the tests A, B, C, need be carried out if the manufacturer can show by computer simulation or calculations of the strength of the component parts of the cab or by other means to the satisfaction of the Technical Service that the cab will not undergo deformation dangerous to the occupants (penetration into the survival space) if subjected to the conditions of the tests.



5.2.   

Survival space required after the test or tests



5.2.1.   

After undergoing each of the tests referred to in paragraphs 5.1.2 or 5.1.3, the cab of the vehicle shall exhibit a survival space allowing accommodation of the manikin defined in Annex 3, Appendix 2, on the seat, when the latter is in its median position, without contact between the test manikin and non-resilient parts with a Shore-Hardness of 50 or more. No account shall be taken of non-resilient parts which can be moved away without any tools from the test manikin by using a force of less than 100 N. To facilitate installation, the manikin may be inserted in dismantled form and assembled in the cab. For this purpose, the seat shall be adjusted to its most rearward position and the manikin completely assembled and so placed that its H point coincides with the R point. The seat shall then be moved forward to its median position for the assessment of the survival space. As an alternative to the test manikin defined in Annex 3, Appendix 2, a fiftieth percentile Hybrid II or III male dummy, with or without measuring instrumentation, the description of which is given in Regulation No 94, may be used.



5.2.2.   

The space so defined shall be verified for every seat provided by the manufacturer.



5.3.   

Other conditions



5.3.1.   

During the tests the components by which the cab is secured to the chassis frame may be distorted or broken, provided that the cab remains attached to the chassis frame by standard fixture attachments and does not unintentionally move, shift or rotate about the attachment points.



5.3.2.   

None of the doors shall open during the tests, but the doors shall not be required to open after testing.



6.   

MODIFICATION AND EXTENSION OF APPROVAL OF THE VEHICLE TYPE



6.1.   

Every modification of the vehicle type shall be notified to the Type Approval Authority which approved the vehicle type. The Type Approval Authority may then either:



6.1.1.   

Consider that the modifications made are unlikely to have an appreciable adverse effect, and that in any case the vehicle still complies with the requirements;



6.1.2.   

Or require a further test report from the Technical Service responsible for conducting the tests.



6.2.
