         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.

         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.

         5.3.1.   
         
            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.

                     The longitudinal members of the chassis frame shall be supported on wooden blocks, rigid composite blocks and/or adjustable metal brackets across their full width and over a length of not less than 150 mm. The front edges of the blocks must not be situated forward of the rearmost point of the cab, nor rearward of the mid-point of the wheel base (see Figure 1 below). At the manufacturer’s request the chassis frame shall be set in the attitude it takes up when loaded.

               Rearward movement of the chassis frame shall be limited by chains or ropes A attached to the front of the chassis frame symmetrically in relation to its longitudinal axis, the points of attachment being not less than 600 mm apart. The chains or ropes shall when tensioned form a downward angle of not more than 25° with the horizontal and their projection on a horizontal plane shall form an angle of not more than 10° with the longitudinal axis of the vehicle (see Figure 1 below). The chains or ropes may cross one another.

                     Tensioning of chains or ropes and rear attachment
                     For tests A and B, the chain or rope С shall, to begin with, be placed under a load of approximately 1 kN. All slack in the four chains or ropes A and В shall then be taken up and chain or rope С shall be subjected to a tensile stress of not less than 10 kN. The angle of chain or rope С with the horizontal shall not exceed 15°. A vertical blocking force of not less than 500 N shall be applied at point D between the chassis frame and the ground (see Figure 1 below). For test C, the chains or ropes B as described above shall be replaced by the chains or ropes E and F (see Figure 2 below).
