distance, any part of the vehicle which is more than 2 m above the ground when the vehicle is unladen shall be excluded.
After applying the test forces specified in Annex 5 for vehicles of the categories N2 with a maximum mass exceeding 8 t, N3, O3 and O4, the maximum ground clearance of the protective device, even when the vehicle is unladen, shall at any point not exceed by more than 60 mm the value before test. For vehicles with a departure angle up to 8° (paragraph 16.1.) the maximum ground clearance shall not exceed 600 mm.
25.8. A practical test shall not be required where it can be shown by calculation that the requirements of Annex 5, paragraph 3., are met. Where a practical test is carried out, the device shall be connected to the chassis side‑members of the vehicle or to a significant part of these or to other structural members.
25.9. For vehicles fitted with a platform lift at the rear, the underrun device may be interrupted for the purposes of the mechanism. In this case, the following special requirements apply:
25.9.1. The maximum lateral clearance measured between the elements of the underrun device and the elements of the platform lift, which move through the interruption when the lift is operated and which make the interruption necessary, may amount to no more than 2.5 cm.
25.9.2. The individual elements of the underrun protection, including those outboard of the lift system, where provided, shall have an effective surface area, in each case, of at least 420 cm2.
25.9.3. For cross-members with a section height of less than 120 mm, the individual elements of the underrun protection, including those outboard of the lift mechanism, where provided, shall have an effective surface area, in each case, of at least 350 cm2.
25.9.4. In the case of vehicles having a width of less than 2,000 mm and where it is impossible to achieve the requirements of paragraphs 25.9.2. and 25.9.3. above, the effective surface may be reduced on the condition that the resistance criteria are met.
26.  Conformity of production
 The conformity of production procedures shall comply with those set out in the Agreement, Schedule 1 (E/ECE/TRANS/505/Rev.3), with the following requirements:
26.1. Every vehicle approved under this Regulation shall be so manufactured as to conform to the type approved by meeting the requirements set out in paragraph 25. above.
26.2. The Type Approval Authority that has granted type approval may at any time verify the conformity control methods applied in each production facility. The normal frequency of these verifications shall be one every two years.
27.  Penalties for non-conformity of production
27.1. The approval granted in respect of a vehicle
