16.   REQUIREMENTS FOR INSTALLATION OF AN APPROVED RUPD
16.1.   For vehicles of the categories N2 with a maximum mass exceeding 8 t, N3, O3 and O4, the ground clearance with respect to the underside of the protective device, even when the vehicle is unladen, shall not exceed:






(a)


450 mm for motor vehicles and trailers with hydropneumatic, hydraulic or pneumatic suspension or a device for automatic levelling according to load. In any case, a departure angle up to 8° according to ISO 612:1978 with a maximum ground clearance of 550 mm shall be deemed to satisfy the requirements.










(b)


500 mm or a departure angle according to ISO 612:1978 of 8°, whichever is less, for vehicles other than those in (a) above. In any case, a departure angle up to 8° according to ISO 612:1978 with a maximum ground clearance of 550 mm shall be deemed to satisfy the requirements.




This requirement applies over the entire width of the motor vehicle or trailer and shall be such that the height above the ground of the points of application of the test forces applied to the device according to Part I of this Regulation and recorded in the type approval communication form (Annex 1, item 7) does not exceed the values in the paragraphs (a) and (b) above, increased by half the minimum section height required for the cross member of the RUPD.
The height requirement for the application of the test forces shall be adjusted to the adjusted ground clearance due to the provisions for the departure angle specified above.
16.2.   For vehicles of categories M, N1, N2 with a maximum mass not exceeding 8 t, O1 and O2, the ground clearance with respect to the underside of the protective device, even when the vehicle is unladen, shall not exceed 550 mm over its entire width and shall be such that the height above the ground of the points of application of the test forces applied to the device according to Part I of this Regulation and recorded in the type approval communication form (Annex 1, item 7) does not exceed 600 mm.
16.3.   The width of the rear protective device shall at no point exceed the width of the rear axle measured at the outermost points of the wheels, excluding the bulging of the tyres close to the ground, nor shall RUPD be more than 100 mm shorter on either side. Where the device is contained in or comprises the vehicle bodywork which itself extends beyond the width of the rear axle, the requirement, that the width of the RUPD shall not exceed that of the rear axle, shall not apply. However, in case of vehicles of categories O1 and O2 where the tyres project for more than half of their width outside the bodywork (excluding the wheel guards) or outside the chassis in the absence of bodywork, the width of the RUPD shall not be less than 100 mm deducted from the distance measured between the innermost points of the tyres, excluding the bulging of the tyres close to the ground, on either side. Where there is more than one rear axle, the width to be considered is that of the widest rear axle. In addition the requirements of paragraphs 3.1.2 and 3.1.3 of Annex 5 relating the distance of the points of application of the test forces from the outer edges of the rear wheels (Annex 1, item 7) shall be verified and recorded in the type approval communication form.
16.4.   For vehicles of categories M, N1, N2 with a maximum mass not exceeding 8 t, O1 and O2, the device shall be so fitted that the horizontal distance between the rear of the cross-member of the device and the most rearward point at the rear extremity of the vehicle, including any platform lift system, does not exceed 400 mm diminished by the largest total deformation including both plastic and elastic deformation (paragraph 7.3 of Part I) measured and recorded during the test at any of the points where the test forces are applied (Annex 1, item 8) during the type approval of the rear underrun protective device in conformity with the provisions of Part I of this Regulation and recorded in the type approval communication form. In measuring this distance, any part of the vehicle which is more than 2 m above the ground for every loading condition of the vehicle shall be excluded.
For vehicles of categories N2 with a maximum mass exceeding 8 t, N3, and vehicles of categories O3 and O4, equipped with a platform lift or being designed as a tipping trailer, the same requirement as above applies; however, for vehicles of these categories, the horizontal distance shall not exceed 300 mm measured to the rear of the cross-member before the test forces are applied.
For vehicles of categories O3 and O4, without any platform lift system and not being designed as a tipping-trailer, the maximum horizontal distances are reduced to 200 mm before the test forces have been applied and 300 mm diminished by the largest total deformation including both plastic and elastic deformation (paragraph 7.3 of Part I) measured and recorded during the test at any of the points where the test forces are applied (Annex 1, item 8).
In any case non-structural protrusions such as tail lamps and those of less than 50 mm of size in any direction, such as rubber bumpers, resilient buffers, hinges and latches shall be excluded from the determination of the most rearward point at the rear extremity.
Before the application of the test forces, the maximum allowed horizontal distance of a single, a segmented or an inclined cross-member of an RUPD is 100 mm between the rear of the cross-member measured at the most forward point and the rear of the cross-member measured at the most rearward point, measured in the longitudinal plane of the vehicle.
16.5.   The device shall be so fitted that after the application of 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.
16.6.   The maximum mass of a vehicle type for which approval is requested shall not exceed the value indicated on the type approval communication form of each approved RUPD intended to be installed on that vehicle.
16.7.   Given the provisions of paragraph 7.2 for adjustable RUPD the label shall be placed clearly and permanently visible at the driver's place or at the rear area of the vehicle next to the RUPD, at a location, which is easily visible.
17.   CONFORMITY OF PRODUCTION
The conformity of production procedures shall comply with those set out in the 1958 Agreement, Schedule 1 (E/ECE/TRANS/505/Rev.3), with the following requirements:






17.1.


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 16 above.










17.2.


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.




18.   PENALTIES FOR NON-CONFORMITY OF PRODUCTION
18.1.   The approval granted in respect of a vehicle type pursuant to this Regulation may be withdrawn if the requirements set forth above are not met.
18.2.   If a Contracting Party to the Agreement applying this Regulation withdraws an approval it has previously granted, it shall forthwith so notify the other Contracting Parties applying this Regulation, by means of a communication form conforming to the model in Annex 2 to this Regulation.
19.   MODIFICATION AND EXTENSION OF APPROVAL OF A VEHICLE TYPE
19.1.   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:






19.1.1.


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; or










19.1.2.


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




19.2.   Confirmation or refusal of approval, specifying the alteration, shall be communicated by the procedure specified in paragraph 15.3 above to the Parties to the Agreement applying this Regulation.
19.3.   The Type Approval Authority issuing the extension of approval shall assign a series number for such an extension and inform thereof the other Parties to the 1958 Agreement applying this Regulation by means of a communication form conforming to the model in Annex 2 to this Regulation.
20.   PRODUCTION DEFINITIVELY DISCONTINUED
If the holder of the approval completely ceases to manufacture a type vehicle approved in accordance with this Regulation, he shall so inform the Type Approval Authority which granted the approval. Upon receiving the relevant communication, that Authority shall inform thereof the other Parties to the 1958 Agreement applying this Regulation by means of a communication form conforming to the model in Annex 2 to this Regulation.
21.   NAMES AND ADDRESSES OF TECHNICAL SERVICES RESPONSIBLE FOR CONDUCTING APPROVAL TESTS, AND OF TYPE APPROVAL AUTHORITIES
The Parties to the 1958 Agreement applying this Regulation shall communicate to the United Nations Secretariat the names and addresses of the Technical Services responsible for conducting approval tests and of the Type Approval Authorities which grant approval and to which forms certifying approval or extension or refusal or withdrawal of approval, issued in other countries, are to be sent.

25.   REQUIREMENTS FOR RUP
25.1.   For vehicles of the categories N2 with a maximum mass exceeding 8 t, N3, O3 and O4, the ground clearance with respect to the underside of the RUP, even when the vehicle is unladen, shall not exceed:






(a)


450 mm for motor vehicles and trailers with hydropneumatic, hydraulic or pneumatic suspension or a device for automatic levelling according to load. In any case a departure angle up to 8° according to ISO 612:1978 with a maximum ground clearance of 550 mm shall be deemed to satisfy the requirements.










(b)


500 mm or a departure angle according to ISO 612:1978 of 8°, whichever is less, for vehicles other than those in (a) above. In any case a departure angle up to 8° according to ISO 612:1978 with a maximum ground clearance of 550 mm shall be deemed to satisfy the requirements.




This requirement applies over the entire width of the motor vehicle or trailer and shall be such that the height above the ground of the points of application of the test forces applied to the device according to Part I of this Regulation and recorded in the type approval communication form (Annex 1, item 7) does not exceed the values in subparagraphs (a) and (b) above, increased by half the minimum section height required for the cross member of the RUPD.
The height requirement for the application of the test forces shall be adjusted to the adjusted ground clearance due to the provisions for the departure angle specified above.
25.2.   For vehicles of categories M, N1, N2 with a maximum mass not exceeding 8 t, O1 and O2, the ground clearance with respect to the underside of the protective device, even when the vehicle is unladen, shall not exceed 550 mm over its entire width and shall be such that the height above the ground of the points of application of the test forces to the RUP does not exceed 600 mm.
25.3.   For vehicles of categories M, N1, N2 with a maximum mass not exceeding 8 t, O1 and O2, the RUP shall be situated as close to the rear of the vehicle as possible. The maximum horizontal distance between the rear of the device and the most rearward point at the rear extremity of the vehicle, including any platform lift system, does not exceed 400 mm measured to the rear of the cross-member and recorded during the test when the test forces are applied.
For vehicles of categories N2 with a maximum mass exceeding 8 t, N3, and vehicles of categories O3 and O4, equipped with a platform lift or being designed as a tipping trailer, the same requirement as above applies; however, for vehicles of these categories, the horizontal distance shall not exceed 300 mm measured to the rear of the cross-member before the test forces are applied.
For RUP for vehicles of categories O3 and O4, without any platform lift system and not being designed as a tipping-trailer, the maximum horizontal distance is reduced to 200 mm before and 300 mm during the test when the test forces are applied.
In any case nonstructural protrusions such as tail lamps and those of less than 50 mm of size in any direction, such as rubber bumpers, resilient buffers, hinges and latches shall be excluded from the determination of the most rearward point at the rear extremity.
Before the application of the test forces the maximum allowed horizontal distance of a single, a segmented or an inclined cross-member of an RUPD is 100 mm between the rear of the cross-member measured at the most forward point and the rear of the cross-member measured at the most rearward point, measured in the longitudinal plane of the vehicle.
25.4.   The width of the RUP shall at no point exceed the width of the rear axle measured at the outermost points of the wheels, excluding the bulging of the tyres close to the ground, nor shall RUP be more than 100 mm shorter on either side. Where the device is contained in or comprises the vehicle bodywork which itself extends beyond the width of the rear axle, the requirement, that the width of the RUP shall not exceed that of the rear axle, shall not apply. However, in case of vehicles of categories O1 and O2 where the tyres project for more than half of their width outside the bodywork (excluding the wheel guards) or outside the chassis in the absence of bodywork, the width of the RUP shall not be less than 100 mm deducted from the distance measured between the innermost points of the tyres, excluding the bulging of the tyres close to the ground, on either side. Where there is more than one rear axle, the width to be considered is that of the widest rear axle. In addition, the requirements of paragraphs 3.1.2 and 3.1.3 of Annex 5 relating the distance of the points of application of the test forces from the outer edges of the rear wheels (Annex 1, item 7) shall be verified and recorded in the type approval communication form.
25.5.   The cross-member shall have a section height of at least 120 mm. The lateral extremities of the cross-member shall not bend to the rear or have a sharp outer edge, this condition is fulfilled when the lateral extremities of the RUP are rounded on the outside and have a radius of curvature of not less than 2,5 mm.
For vehicles of the categories M, N1, N2 with a maximum mass not exceeding 8 t, O1, O2, vehicles of category G and vehicles fitted with a platform lift, the cross-member shall have a section height of at least 100 mm.
25.6.   The RUP may be so designed to have several positions at the rear of the vehicle. In this event, there shall be a guaranteed method of securing it in the service position so that any unintentional change of position is precluded. The force applied by the operator to vary the position of the RUP shall not exceed 40 daN.
For RUP that are designed to have several positions at the rear of the vehicle a label shall be provided in the language(s) of the country where the device is sold.
Label minimum size: 60 × 120 mm.
The label shall be placed clearly and permanently visible at the rear area of the vehicle next to the RUP to inform the operator about the standard position of the RUP to offer effective protection against under-running.
25.7.   The RUP shall offer adequate resistance to forces applied parallel to the longitudinal axis of the vehicle and be connected, when in the service position, with the chassis side-members or whatever replaces them. This requirement will be satisfied if it is shown that both during and after the application of the forces described in Annex 5 the horizontal distance between the rear of the RUP and the most rearward point at the rear extremity of the vehicle, including any platform lift system, does not exceed 400 mm at any of the points where the test forces are applied. In measuring this 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 1958 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 type pursuant to this Regulation may be withdrawn if the requirements set forth above are not met or if the vehicle has failed to pass the test prescribed in Annex 5.
27.2.   If a Contracting Party to the Agreement applying this Regulation withdraws an approval it has previously granted, it shall forthwith so notify the other Contracting Parties applying this Regulation, by means of a communication form conforming to the model in Annex 3 to this Regulation.
28.   MODIFICATION AND EXTENSION OF APPROVAL OF A VEHICLE TYPE
28.1.   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:






28.1.1.


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; or










28.1.2.


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




28.2.   Confirmation or refusal of approval, specifying the alterations shall be communicated by the procedure specified in paragraph 24.3 above to the Parties to the Agreement applying this Regulation.
28.3.   The Type Approval Authority issuing the extension of approval shall assign a series number for such an extension and inform thereof the other Parties to the 1958 Agreement applying this Regulation by means of a communication form conforming to the model in Annex 3 to this Regulation.
29.   PRODUCTION DEFINITIVELY DISCONTINUED
If the holder of the approval completely ceases to manufacture a vehicle type approved in accordance with this Regulation, he shall so inform the Type Approval Authority which granted the approval. Upon receiving the relevant communication that Authority shall inform thereof the other Parties to the 1958 Agreement applying this Regulation by means of a communication form conforming to the model in Annex 3 to this Regulation.
30.   NAMES AND ADDRESSES OF TECHNICAL SERVICES RESPONSIBLE FOR CONDUCTING APPROVAL TESTS, AND OF TYPE APPROVAL AUTHORITIES
The Parties to the 1958 Agreement applying this Regulation shall communicate to the United Nations Secretariat the names and addresses of the Technical Services responsible for conducting approval tests and of the Type Approval Authorities which grant approval and to which forms certifying approval or extension or refusal or withdrawal of approval, issued in other countries, are to be sent.

Foremost fixing poing (e.g. bolt or weld)

1.3.   At the request of the manufacturer and with the consent of the Technical Service the test procedure described in paragraph 3 may be simulated by calculation.
The mathematical model shall be validated in comparison with the actual test conditions. To that effect, a physical test shall be conducted for the purposes of comparing the results obtained when using the mathematical model with the results of a physical test. Comparability of the test results shall be proven. A validation report shall be drafted by the manufacturer or by the technical service and submitted to the Type Approval Authority.
Any change made to the mathematical model or to the software likely to invalidate the validation report shall be brought to the attention of the Type Approval Authority which may require a new validation process to be conducted.
1.4.   In the case of an RUPD where the cross-member does not have a vertical flat surface of at least 50 per cent of the minimum section height of the cross-member according to paragraph 7.1 or 25.5 of this Regulation at the height of the points of application of the test forces according to paragraph 16.1 or 25.1, the manufacturer shall supply the Technical Service with a device that allows the application of horizontal test loads on the cross-member with the test equipment used by the Technical Service. The device shall not modify the dimensional and mechanical characteristics of the RUPD or increase its resistance during test. The device shall neither be rigidly fixed to the RUPD nor to the test equipment.
2.   TEST CONDITIONS FOR VEHICLES
2.1.   The vehicle shall be at rest on a level, flat, rigid and smooth surface.
2.2.   The front wheels shall be in the straight-ahead position.
2.3.   The tyres shall be inflated to the pressure recommended by the vehicle manufacturer.
2.4.   The vehicle may, if necessary to achieve the test forces required in paragraph 3.1 below, be restrained by any method, this method to be specified by the vehicle manufacturer.
2.5.   Vehicles equipped with hydropneumatic, hydraulic or pneumatic suspension or a device for automatic levelling according to load shall be tested with the suspension or device in the normal running condition specified by the manufacturer.
3.   TEST PROCEDURE
3.1.   The requirements of paragraphs 7.3 and 25.7 of this Regulation shall be verified by means of suitable test mandrels; the forces for tests prescribed in paragraphs 3.1.1 and 3.1.2 below shall be applied separately and consecutively, via a surface not more than 250 mm in height (but covering the maximum section height of the cross-member or RUP, the exact height shall be indicated by the manufacturer) and 200 mm wide, with a radius of curvature of 5 ± 1 mm at the vertical edges. The RUP shall offer adequate resistance to forces applied parallel to the longitudinal axis of the vehicle. The surface shall not be rigidly fixed to the RUPD or to the RUP and shall be articulated in all directions. The height above the ground of the centre of the surface shall be defined by the manufacturer within the lines that bound the device horizontally. When the test is carried out on a vehicle the height shall not, however, exceed the height as specified in paragraphs 16.1 and 16.2 or as specified in paragraphs 25.1 and 25.2 of this Regulation when the vehicle is unladen. The order in which the forces are applied may be specified by the manufacturer.
The device used to distribute the test force over the stated flat surface shall be connected to the force actuator through a swivel joint. The arrangement of the force actuator, whether pulling or pushing, shall be arranged such that it does not add any stiffness or stability to the underrun protection system structure, i.e. it shall neither increase the instability threshold force nor decrease the maximum deflection of the underrun protection system.
3.1.1.   A horizontal force of 180 kN or 85 per cent of the force generated by the maximum mass of the vehicle, whichever is the lesser, shall be applied consecutively to two points situated symmetrically about the centre line of the device or of the vehicle whichever is applicable at a minimum distance apart of 700 mm and a maximum of 1 m. The exact location of the points of application shall be specified by the manufacturer.
Notwithstanding the provision above for non-separate cab vehicles of category N2 with a maximum mass not exceeding 8 t, the horizontal forces may be reduced to 100 kN or 50 per cent.
3.1.2.   In the cases defined in paragraphs 1.1.1 and 1.1.2 of this annex a horizontal force of 100 kN or 50 per cent of the force generated by the maximum mass of the vehicle, whichever is the lesser, shall be applied consecutively to two points located 300 ± 25 mm from the longitudinal planes tangential to the outer edges of the wheels on the rear axle or of the RUPD, if it exceeds the width of the rear axle, and to a third point located on the line joining these two points, in the median vertical plane of the vehicle.
Notwithstanding the provision above for non-separate cab vehicles of category N2 with a maximum mass not exceeding 8 t, the horizontal forces may be reduced to 50 kN or 25 per cent.
3.1.3.   Upon request of the manufacturer, the force levels can be reduced to 80 per cent of the requirement given in paragraphs 3.1.1 to 3.1.2 for the vehicles listed in Annex 6.
3.2.   Replacement force application points
If any point defined under paragraph 3.1 is located within the interruption area of the underrun protection device as mentioned in paragraph 7.4 or 25.8 of this Regulation, the test forces shall be applied at replacement points located:






3.2.1.
