COUNCIL DIRECTIVEof 26 May  1986on rear-mounted roll-over protection structures of narrow-track wheeled agricultural and  forestry tractors(86/298/EEC)THE COUNCIL OF THE EUROPEAN COMMUNITIES,Having regard  to the Treaty establishing the European Economic Community, and in particular Article 100  thereof,Having regard to the proposal from the Commission (1),Having regard to the opinion of the  European Parliament (2),Having regard to the opinion of the Economic and Social Committee  (3),Whereas Council Directive 74/150/EEC of 4 March 1974 on the approximation of the laws of the  Member States relating to the type-approval of wheeled agricultural or forestry tractors (4), as  last amended by the Act of Accession of Spain and Portugal, lays down that the necessary provisions  for the implementation of the EEC type-approval procedure in respect of individual tractor parts or  characteristics should be specified in special directives; whereas the provisions relating to  roll-over protection structures and their attachments to tractors were laid down by Directives  77/536/EEC (5) and 79/622/EEC (6), as last amended by the Act of Accession of Spain and Portugal;  whereas these two Directives cover respectively dynamic and static testing procedures - either of  which may be employed by manufacturers for the present - and relate to standard tractors, that is,  tractors having a maximum ground clearance of 1 000 mm and a fixed or adjustable track width of one  of the driving axles of not less than 1 150 mm and weighing between 1,5 and 4,5 tonnes in the case  of tractors covered by the 'dynamic testing' Directive and not less than 800 kilograms in the case  of tractors covered by the 'static testing' Directive;Whereas the tractors covered by this  Directive have a maximum ground clearance of 600 mm, a minimum track width of both axles of less  than 1 150 mm and a mass greater than 600 kilograms; whereas the roll-over protection structures of  these tractors, which are used for specific activities, can be made subject to specific requirement  or requirements other than those of Directive 77/536/EEC and 79/622/EEC; Whereas the technical requirements with which such 'narrow-track' tractors must comply  pursuant to national laws relate inter alia to roll-over protection structures and to their  attachment to the tractor; whereas those requirements differ from one Member State to another;  whereas it is therefore necessary that all Member States adopt the same requirements either in  addition to or in place of their existing rules in order, in particular, to allow the EEC  type-approval procedure which was the subject of Directive 74/150/EEC to be introduced in respect  of each type of tractor;Whereas this Directive covers roll-over protection structures of the  rear-mounted rollbar, frame or cab type having a zone of clearance whose upper limit is 900 mm  above the seat reference point in order to provide a sufficiently large area or unobstructed space  for the protection of the driver; whereas another special Directive will be adopted in respect of  roll-over protection structures having two pillars mounted in front of the driver;Whereas a  harmonized component type-approval procedure for roll-over protection structures and their  attachment to the tractor makes it possible for each Member State to check compliance with the  common construction and testing requirements and to inform the other Member States of its findings  by sending them copies of the component type-approval certificate completed for each type of  roll-over protection structure and its attachment to the tractor; whereas the placing of an EEC  component type-approval mark on all structures manufactured in conformity with the approved type  obviates any need for technical checks on those structures in the other Member States; whereas  common requirements concerning other elements and characteristics of the roll-over protection  structure, in particular, devices to prevent continuous roll-over if the tractor overturns, and  protection of occupants, will be laid down at a later date;Whereas the harmonized requirements are  intended principally to ensure safety on the road and at work throughout the Community; whereas,  for this reason, it is necessary to introduce the obligation for tractors covered by this Directive  to be fitted with roll-over protection structures;Whereas the approximation of the national laws  relating to these tractors entails reciprocal recognition by Member States of the checks carried  out by each of them on the basis of the common requirements, HAS ADOPTED THIS DIRECTIVE:Article 1This Directive shall apply to tractors as  defined in Article 1of Directive 74/150/EEC having the following characteristics:ground clearance  of not more than 600 mm measured beneath the lowest points of the front or rear axles, allowing for  the differential,fixed or adjustable minimum track width of one of the two axles less than 1 150  mm; under no circumstances must the outer edge of the tyres on the other axlego beyond the outer  edge of the tyres on the axle of1 150 mm minimum track width,mass greater than 600 kilograms and  corresponding to the unladen weight of the tractor as defined in section 2.4 of Annex I to  Directive 74/150/EEC, including the roll-over protection structure fitted in compliance with this  Directive and tyres of the largest size recommended by the manufacturer.Article 21.  Each Member  State shall grant EEC component type-approval for any type of roll-over protection structure and  its tractor attachment which satisfies the construction and testing requirements laid down in  Annexes I to IV.2.  A Member State which has granted EEC component type-approval shall take the  measures required to verify, in so far as is necessary and if need be in cooperation with the  competent authorities in the other Member States, that production models conform to the approved  type. Such verification shall be limited to spot checks.Article 3Member States shall, for each  type of roll-over protection structure and its tractor attachment which they approve pursuant to  Article 2, issue to the manufacturer of the tractor or of the roll-over protection structure, or to  his authorized representative, an EEC component type-approval mark conforming to the model shown in  Annex VI.Member States shall take all appropriate measures to prevent the use of marks liable to  create confusion between roll-over protection structures which have been component type-approved  pursuant to Article 2 and other devices.Article 41.  N° Member State may prohibit the placing on  the market of roll-over protection structures or their attachmentto the tractors for which they  are intended on grounds relating to their construction if they bear the EEC component type-approval  mark.2.  Nevertheless, a Member State may prohibit the placing on the market of roll-over  protection structures bearing the EEC component type-approval mark which consistently fail to  conform to the approved type.That State shall forthwith inform the other Member States and the  Commission of the measures taken, specifying the reasons for its decision.Article 5The competent  authorities of each Member State shall, within one month, send to the competent authorities of the  Member State a copy of the component type-approval certificates, an example of which is given in  Annex VII, completed for each type of roll-over protection structure which they approve or refuse  to approve.Article 61.  If the Member State which has granted EEC component type-approval finds  that a number of roll-over protection structures and their tractor attachments bearing the same EEC  component type-approval mark do not conform to the type which it has approved, it shall take the  necessary measures to ensure that production models conform to the approved type. The competent  authorities of that State shall advise those of the other Member States of the measures taken which  may, if necessary, where there is serious and repeated failure to conform, extend to withdrawal of  EEC component type-approval. The said authorities shall take the same measures if they are informed  by the competent authorities of another Member State of such failure to conform.2.  The competent  authorities of the Member States shall within one month inform each other of any withdrawal of EEC  component type-approval and of the reasons for any such measure.Article 7Any decision taken  pursuant to the provisions adopted in implementation of this Directive to refuse or withdraw  component type-approval for roll-over protection structures and their tractor attachments, or to  prohibit their placing on the market or their use, shall set out in detail the reasons on which it  is based. Such decisions shall be notified to the party concerned, who shall at the same time be  informed of the remedies available to him under the laws in force in the Member States and of the  time limits allowed for the exercise of such remedies.Article 8N° Member State may refuse to  grant EEC type-approval or national type-approval in respect of a tractor on groundsrelating to  roll-over protection structures or their tractor attachment if these bear the EEC component  type-approval mark and if the requirements laid down in Annex VIII have been satisfied.Article  9N° Member State may refuse or prohibit the sale, registration, entry into service or use of any  tractor on grounds relating to the roll-over protection structure and its tractor attachment if  these bear the EEC component type-approval mark and if the requirements laid down in Annex VIII  have been met.Article 10This Directive shall not affect the right of Member States to specify -  in due compliance with the Treaty - the requirements they deem necessary to ensure that workers are  protected when using the tractors in question, provided this does not mean that the protection  structures are modified in a way unspecified in this Directive.Article 111.  In connection with  EEC type-approval, any tractor to which Article 1 refers must be fitted with a roll-over protection  structure.2.  Where the protection structure is not one having two pillars mounted in front of the  driver's seat, the structure referred to in paragraph 1 must comply with the requirements laid down  in Annexes I to IV to this Directive or to Directives 77/536/EEC or 79/622/EEC. Article 12Any amendments necessary in order to adapt the requirements of the Annexes to this  Directive so as to take account of technical progress shall be adopted in accordance with the  procedure laid down in Article 13 of Directive 74/150/EEC.Article 13Within 18 months of the  notification of this Directive, the Council, acting on a proposal from the Commission, on the basis  of the provisions of the Treaty, shall adopt a Directive supplementing this Directive by means of  provisions introducing the additional impact tests in the dynamic test procedure.Article 141.   Member States shall bring into force the provisions necessary in order to comply with this  Directive within24 months of its notification (1). They shall forthwith inform the Commission  thereof.2.  Member States shall ensure that the texts of the main provisions of national law which  they adopt in the field covered by this Directive are communicated to the Commission.Article  15This Directive is addressed to the Member States.Done at Brussels, 26 May  1986.For the CouncilThe PresidentG.

ANNEX IIITEST PROCEDUREA. Dynamic tests1.IMPACT AND CRUSHING TESTS1.1.Impact at the  rear1.1.1.The tractor shall be so placed in relation to the pendulum block that the block will  strike the protection structure when the impact face of the block and the supporting chains or wire  ropes are at an angle with the vertical plane equal to mt/100 with a 20g maximum, unless, during  deflection, the protection structure at the point of contact forms a greater angle to the vertical.  In this case the impact face of the block shall be adjusted by means of an additional support so  that it is parallel to the protection structure at the point of impact at the moment of maximum  deflection, the supporting chains or wire ropes remaining at the angle defined above.The suspended  height of the block shall be adjusted, and necessary steps taken so as to prevent the block from  turning about the point of contact.The point of impact shall be that part of the protection  structure likely to hit the ground first in a rearward overturning accident, normally the upper  edge. The position of the centre of gravity of the block shall be one-sixth of the width of the top  of the protection structure inwards from a vertical plane parallel to the median plane of the  tractor touching the outside extremity of the top of the protection structure.If the structure is  curved or protruding at this point, wedges enabling the impact to be applied thereon will have to  be added, without thereby reinforcing the structure.1.1.2.The tractor shall be lashed to the ground  by means of four wire ropes, one at each end of both axles, arranged as indicated in Figure 5 of  Annex IV. The front and rear lashing points shall be located at a distance such that the wire ropes  make an angle of less than 30g with the ground. The rear lashings shall in addition be so arranged  that the point of convergence of the two wire ropes is located in the vertical plane in which the  centre of gravity of the block travels.The wire ropes must be tensioned such that the tyres undergo  the deflections given in Item 6.2 ofAnnex II A.With the wire ropes tensioned, the wedging beam  shall be placed in front of and tight against the rear wheels and then fixed to the ground.1.1.3.If  the tractor is of the articulated type, the point of articulation shall, in addition, be supported  by a wooden block at least 100 mm square and firmly lashed to the ground.1.1.4.The pendulum block  shall be pulled back so that the height of its centre of gravity above that at the point of impact  is given by one of the following two formulae:H = 2,165×10-8 mt L$ or H = 5,73×10-2 I. The block must then be released so as to strike the protection structure.1.2.Impact at the  front1.2.1.The tractor shall be so placed in relation to the pendulum block that the block will  strike the protection structure when the impact face of the block and the supporting chains or wire  ropes are at an angle with the vertical plane, equal to mt/100 with a 20g maximum, unless, during  deflection, the protection structure at the point of contact forms a greater angle to the vertical.  In this case the impact face of the block shall be adjusted by means of an additional support so  that it is parallel to the protection structure at the point of impact at the moment of maximum  deflection, the supporting chains or wire ropes remaining at the angle defined above.The suspended  height of the pendulum block shall be adjusted and necessary steps taken so as to prevent the block  from turning about the point of contact.The point of impact shall be that part of the protection  structure likely to hit the ground first if the tractor overturns sideways while travelling  forward, normally the upper edge. The position of thecentre of gravity of the block shall be  one-sixth of the width of the top of the protection structure inwards from a vertical plane  parallel to the median plane of the tractor touching the outside extremity of the top of the  protection structure.If the structure is curved or protruding at this point, wedges enabling the  impact to be applied thereon will have to be added, without thereby reinforcing the  structure.1.2.2.The tractor shall be lashed to the ground by means of four wire ropes, one at each  end of both axles, arranged as indicated in Figure 6 of Annex IV. The front and rear lashing points  shall be located at a distance such that the wire ropes make an angle of less than 30g with the  ground. The rear lashings shall, in addition, be so arranged that the point of convergence of the  two wire ropes is located in the vertical plane in which the centre of gravity of the pendulum  block travels.The wire ropes must be tensioned such that the tyres undergo the deflections given in  Item 6.2 ofAnnex II A.With the wire ropes tensioned, the wedging beam shall be placed firmly  behind the rear wheels and then fixed to the ground.1.2.3.If the tractor is of the articulated  type, the point of articulation shall in addition be supported by a wooden block at least 100 mm  square and firmly lashed to the ground.1.2.4.The pendulum block shall be pulled back so that the  height of its centre of gravity above that at the point of impact is given by one of the following  two formulae, to be chosen according to the reference mass of the tractors subjected to the tests:H  =  25 + 0,07 mt for tractors with a reference mass of less than 2 000 kilograms,H = 125 + 0,02 mt  for tractors with a reference mass of more than 2 000 kilograms.The pendulum block must then be  released so as to strike the protection structure.1.3.Impact from the side1.3.1.The tractor shall  be so placed in relation to the pendulum block that the block will strike the protection structure  when the impact face of the weight and the supporting chains or wire ropes are vertical unless,  during deflection, the protection structure at the point of contact forms an angle to the vertical.  In this case the impact face of the block shall be adjusted by means of an additional support so  that it is parallel to the protection structure at the point of impact at the moment of maximum  deflection, the supporting chains or wire ropes remaining vertical on impact.The suspended height  of the block shall be adjusted and necessary steps taken so as to prevent the block from turning  about the point of contact.The point of impact shall be that part of the protection structure  likely to hit the ground first in a sideways overturning accident, normally the upper edge. Unless  it is certain that another part of this edge would hit the ground first, the point of impact shall  be in the plane at right angles to the median plane and passing 200 mm in front of the seat  reference point, the seat being set at the mid position of the longitudinal seat  adjustment.1.3.2.The tractor wheels on the side which is to receive the impact shall be lashed to  the ground by means of wire ropes passing over the corresponding ends of the front and rear axles.  The wire ropes shall be tensioned to produce the tyre deflection values given in Item 6.2 of Annex  II A on the side which is to receive the impact.With the wire ropes tensioned, the wedging beam  shall be placed on the ground, pushed tight against the tyres on the side opposite that which is to  receive the impact and then fixed to the ground. It may be necessary to use two beams or wedges if  the outer sides of the front and rear tyres are not in the same vertical plane.The prop shall then  be placed as indicated in Figure 7 of Annex IV against the rim of the wheel opposite to the impact,  pushed firmly against the rim and then fixed at its base.The length of the rop shall be chosen such  that it makes an angle of 30 p 3g with the ground when in position against the rim. In addition,  its length must, if possible, be between 20 and 25 times greater than its thickness and its width  between two and three times greater than its thickness. The props shall be shaped at both ends as  shown in the details of Figure 7 of Annex IV.1.3.3.If the tractor is of the articulated type, the  point of articulation shall, in addition, be supported by a wooden block at least 100 mm square and  laterally supported by a device similar to that provided for in Item 1.3.2 against the rear wheel.  The point of articulation shall then be lashed firmly to the ground. 1.3.4.The pendulum block shall be pulled back so that the height of its centre of gravity above  that at the point of impact is given by one of the following two formulae, to be chosen according  to the reference mass of the tractors subjected to the tests:H =  25 + 0,20 mt for tractors with a  reference mass of less than 2 000 kilograms,H = 125 + 0,15 mt for tractors with a reference mass of  more than 2 000 kilograms.The pendulum block must then be released so as to strike the protection  structure.1.4.Crushing at the rearThe beam shall be positioned over the rear uppermost structural  member(s) and the resultant of the crushing forces shall be located in the tractor's median plane.A  force, Fv = 20 mt shall be applied.Where the rear part of the protection structure roof will not  sustain the full crushing force, the force shall be applied until the roof is deflected to coincide  with the plane joining the upper part of the protection structure with that part of the rear of the  tractor capable of supporting the vehicle's mass when overturned.The force shall then be removed,  and the tractor or loading force repositioned so that the beam is over that point of the protection  structure which would then support the tractor when completely overturned.The force Fv shall then  be applied.It shall be applied for a minimum of five seconds following the cessation of any  visually detectable deflection.1.5.Crushing at the frontThe beam shall be positioned over the front  uppermost structural member(s) and the resultant of the crushing forces shall be located in the  tractor's median plane.A force, Fv = 20 mt shall be applied.Where the front part of the protection  structure roof will not sustain the full crushing force, the force shall be applied until the roof  is deflected to coincide with the plane joining the upper part of the protection structure with  that part of the front of the tractor capable of supporting the vehicle's mass when overturned.The  force shall then be removed, and the tractor or loading force repositioned so that the beam is over  that point of the protection structure which would then support the tractor when completely  overturned.The force Fv shall then be applied.It shall be applied for a minimum of five seconds  following the cessation of any visually detectable deflection.1.6.Additional testsIf cracks or  tears which cannot be considered negligible appear during a crushing test, a second similar  crushing test, but with a force equal to 1,2 Fv, shall be applied immediately after the crushing  test which caused the cracks or tears to appear.2.ZONE OF CLEARANCE2.1.The zone of clearance is  shown in Figures 1, 2a, 2b, 2c, 2d and 2e of Annex IV.The zone is defined on the basis of a  'vertical reference plane', generally longitudinal to the tractor and passing through the seat  reference point and the centre of the steering wheel. This plane must be able to move horizontally  with the seat and the steering wheel during the impact but to remain perpendicular to the floor of  the tractor or of the protection structure if this is resiliently mounted.2.2.The zone is bounded  by the following planes, the tractor being on a horizontal surface and, where the steering wheel is  adjustable, its position adjusted for normal seated driving.2.2.1.A horizontal plane - A1B1B2A2 -  900 mm above the seat reference point. 2.2.2.An inclined plane - H1H2G2G1 - perpendicular to the vertical reference plane and including a  point 900 mm directly above the seat reference point and the rearmost point of the seat  backrest.2.2.3.A cylindrical surface - A1A2H2H1 - which is perpendicular to the reference plane,  has a radius of120 mm and is tangential to the planes defined above in Items 2.2.1 and  2.2.2.2.2.4.A cylindrical surface - B1C1C2B2 - perpendicular to the reference plane, having a  radius of 900 mm and extending forward by 400 mm the plane defined in Item 2.2.1 above, to which it  is tangential, following a horizontal line 150 mm forward of the seat reference point.2.2.5.A  inclined plane - C1D1D2C2 - perpendicular to the reference plane, extending the surface defined in  Item 2.2.4 above and passing through a point 40 mm from the outer edge of the steering  wheel.2.2.6.A vertical plan - D1K1E1E2K2D2 - perpendicular to the reference plane and passing 40 mm  in front of the other edge of the steering wheel.2.2.7.A horizontal plane - E1F1P1N1N2P2F2E2 -  passing through the seat reference point.2.2.8.A curvilinear surface - G1L1M1N1N1M2L2G2 -  perpendicular to the reference plaen and in contact with the back of the seat backrest.2.2.9.Two  vertical planes - K1I1F1E1 and K2I2F2E2 - parallel to the reference plane, 250 mm either side of  this plane, and bounded towards the top 300 mm above the horizontal plane passing through the seat  reference point.2.2.10.Two inclined and parallel planes - A1B1C1D1K1I1L1G1H1 and A2B2C2D2K2I2L2G2H2  - starting from the upper edge of the planes defined in Item 2.2.9 above and joining the horizontal  plane defined in Item 2.2.1 above at least 100 mm from the reference plane on the side where the  impact is applied.2.2.11.Two vertical planes - Q1P1N1M1 and Q2P2N2M2 - parallel to the reference  plane, 200 mm either side of this plane, and bounded towards the top 300 mm above the horizontal  plane passing through the seat reference point.2.2.12.Two portions - I1Q1P1F1 and I2Q2P2F2 - of a  vertical plane, perpendicular to the reference plane and passing 350 mm in front of the seat  reference point.2.2.13.Two portions - I1Q1M1L1 - and I2Q2M2L2 - of the horizontal plane passing 300  mm above the seat reference point.2.3.Seat location and seat reference point2.3.1Seat reference  point2.3.1.1.The refernce point shall be established using the apparatus illustrated in Figures 3  and 3b of Annex IV. The apparatus shall consist of a seat pan board and backrest boards. The lower  backrest board shall be jointed in the region of the ischium humps (A) and loin (B), the joint (B)  being adjustable in height.2.3.1.2.The reference point is defined as the point in the median  longitudinal plane of the seat where the tangential plane of the lower backrest and a horizontal  plane intersect. This horizontal plane cuts the lower surface of the seat pan board 150 mm in front  of the abovementioned tangent.2.3.1.3.The apparatus shall be positioned on the seat. It shall then  be loaded with a force of 550 N at a point50 mm in front of joint (A), and the two parts of the  backrest board shall be lightly pressed tangentially against the backrest.2.3.1.4.If it is not  possible to determine definite tangents to each area of the backrest (above and below the lumbar  region) the following must be done:2.3.1.4.1.Where no definite tangent to the lower area is  possible the lower part of the backrest board is pressed against the backrest  vertically.2.3.1.4.2.Where no definite tangent to the upper area is possible the joint (B) is fixed  at a height of 230 mm above the lower surface of the seat pan board, the backrest board being  perpendicular to the latter. Then the two parts of the backrest board are lightly pressed against  the backrest.2.3.2.Seat position and adjustment for determining the location of the seat reference  point2.3.2.1.Where the seat position is adjustable, the seat must be adjusted to its rear uppermost  position.2.3.2.2.Where the inclination of the backrest and seat pan is adjustable, these must be  adjusted so that the reference point is in its rear uppermost position.2.3.2.3.Where the seat is  equipped with suspension, the latter must be blocked at mid-travel, unless this is contrary to the  instructions clearly laid down by the seat manufacturer. 3.MEASUREMENTS TO BE MADE3.1.Fractures and cracksAfter each test all structural members, joints and  fastening systems shall be visually examined for fractures or cracks, any small cracks in  unimportant parts being ignored.Any tears caused by the edges of the pendulum weight shall be  ignored.3.2.Zone of clearance3.2.1.During each test an examination shall be made to see whether any  part of the protection structure has entered the zone of clearance round the driver's seat as  defined in Item 2 of this Annex.3.2.2.In addition, an examination shall be made to determine  whether any part of the zone of clearance is outside the protection of the protection structure.  For this purpose it shall be considered to be outside the protection of the roll-over protection  structure if any part of it would have come into contact with flat ground if the tractor had  overturned towards the direction from which the impact came. For this purpose the front and rear  tyre and track setting shall be assumed to be the smallest specified by the  manufacturer.3.3.Elastic deflection (on side impact)The elastic deflection shall be measured 900 mm  above the seat reference point, in the vertical plane passing through the point of impact. For this  measurement, apparatus as shown in Figure 9 ofAnnex IV shall be used.3.4.Permanent deflectionAfter  the final crushing test, the permanent deflection of the protection structure shall be recorded.  For this purpose, before the start of the test, the position of the main protection structure  members in relation to the seat reference point shall be recorded. B. Static tests1.LOADING AND CRUSHING TESTS1.1.Loading at the rear1.1.1.The load shall be applied  horizontally, in a vertical plane parallel to the tractor's median plane.The load application point  shall be that part of the protection structure likely to hit the ground first in a rearward  overturning accident, normally the upper edge. The vertical plane in which the load is applied  shall be located at a distance of one-third of the external width of the upper part of the  structure from the median plane.If the structure is curved or protruding at this point, wedges  enabling the load to be applied thereon will have to be added, without thereby reinforcing the  structure.1.1.2.The assembly defined in Item 1.3.1 of Annex II shall be lashed to the ground as  described in Item 3 of Annex II B.1.1.3.The energy absorbed by the protection structure during the  test shall be at leastEil = 2,165×10-7 mt L$ or Eil = 0,574×I. 1.2.Loading at the front1.2.1.The load shall be applied horizontally in a vertical plane parallel  to the tractor's median plane.The point of application shall be that part of the protection  structure likely to hit the ground first if the tractor overturns sideways while travelling  forward, i.e. normally the upper egde. The point of application of the load shall be one-sixth of  the width of the top of the protection structure inwards from a vertical plane parallel to the  median plane of the tractor touching the outside extremity of the top of the protection  structure.If the structure is curved or protruding at this point, wedges enabling the load to be  applied thereon will have to be added, without thereby reinforcing the structure.1.2.2.The assembly  defined in Item 1.3.1 of Annex II shall be anchored to the ground as described in Item 3 of Annex  II B.1.2.3.The energy absorbed by the protection structure during the test shall be at leastEil =  500 + 0,5 mt1.3.Loading from the side1.3.1.The side loading shall be applied horizontally, in a  vertical plane perpendicular to the tractor's median plane and passing 200 mm in front of the seat  reference point, the seat being at the mid position of the longitudinal seat adjustment.The load  application point shall be that part of the protection structure likely to hit the ground first in  a sideways overturning accident, normally the upper edge.1.3.2.The assembly defined in Item 1.3.1  of Annex II shall be lashed to the ground as described in Item 3 of Annex II B.1.3.3.The energy  absorbed by the protection structure during the test shall be at leastEis = 1,75 mt1.4.Crushing at  the rearAll provisions are identical to those given in Item 1.4 of Annex III A.1.5.Crushing at the  frontAll provisions are identical to those given in Item 1.5 of Annex III A.1.6.Overload  test1.6.1.An overload test shall be carried out where the force decreases by more than 3 % during  the last 5 %of the deflection reached when the energy required is absorbed by the structure (see  Figure 10b ofAnnex IV). 1.6.2.The overload test involves the gradual increase of the horizontal load by increments of 5 %  of the initial energy requirement up to a maximum of 20 % of energy added (see Figure 10c of Annex  IV).1.6.2.1.The overload test is satisfactory if, after each increase by 5 %, 10 % or 15 % in the  energy required, the force decreases by less than 3 % for a 5 % increment and remains more than 0,8  Fmax.1.6.2.2.The overload test is satisfactory if, after the structure has absorbed 20 % of the  added energy, the force exceeds 0,8 Fmax.1.6.2.3.Additional cracks or tears and/or entry into or  lack of protection of the zone of clearance due to elastic deflection are permitted during the  overload test. However, after the removal of the load, the structure shall not enter the zone of  clearance, which shall be completely protected.1.7.Crushing testIf cracks or tears which cannot be  considered as negligible appear during a crushing test, a second, similar crushing, but with a  force of 1,2 Fv, shall be applied immediately after the crushing which caused the cracks or tears  to appear.2.ZONE OF CLEARANCEThe zone of clearance is identical to that described in Item 2 of  Annex III A above, except that the word 'impact' is to be replaced by 'load' in the last line of  Item 2.2.10.3.MEASUREMENTS TO BE MADE3.1.Fractures and cracksAfter each test all structural  members, joints and attachment systems shall be visually examined for fractures or cracks, any  small cracks in unimportant parts being ignored.3.2.Zone of clearance3.2.1.During each test an  examination shall be made to see whether any part of the protection structure has entered the zone  of clearance as defined in Item 2 above.3.2.2.In addition, an examination shall be made to  determine whether any part of the zone of clearance is outside the protection of the protection  structure. For this purpose it shall be considered to be outside the protection of the protection  structure if any part of it would have come into contact with flat ground if the tractor had  overturned towards the direction from which the impact came. For this purpose the front and rear  tyres and track setting shall be assumed to be the smallest specified by the  manufacturer.3.3.Elastic deflection (under side loading)The elastic deflection shall be measured  900 mm above the reference point, in the vertical plane in which the load is applied. For this  measurement, any apparatus similar to that illustrated in Figure 9 of Annex IV, may be  used.3.4.Permanent deflectionAfter the tests, the permanent deflection of the protection structure  shall be recorded. For this purpose, before the start of the tests, the position of the main  protection structure members in relation to the seat reference point shall be recorded.
