                                          DIRECTIVE …/…/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL

                                                                      of […]

                           relating to the roll-over protection structures of wheeled agricultural or forestry tractors

                                                                (Codified version)

                                                              EXPLANATORY MEMORANDUM

1.    In the context of a people’s Europe, the Commission attaches great importance to simplifying and clarifying Community law so as to make  it
       clearer and more accessible to the ordinary citizen, thus giving him new opportunities and the chance to make use of the  specific  rights
       it gives him.

       This aim cannot be achieved so long as numerous provisions that have  been  amended  several  times,  often  quite  substantially,  remain
       scattered, so that they must be sought partly in the original instrument and partly in later amending ones.  Considerable  research  work,
       comparing many different instruments, is thus needed to identify the current rules.

       For this reason a codification of rules that have frequently been amended  is  also  essential  if  Community  law  is  to  be  clear  and
       transparent.

2.    On 1 April 1987 the Commission therefore decided[1] to instruct its staff that all legislative acts should be codified after no  more  than
       ten amendments, stressing that this is a minimum requirement and that departments should endeavour to codify at even shorter intervals the
       texts for which they are responsible, to ensure that the Community rules are clear and readily understandable.

3.    The Conclusions of the Presidency of the Edinburgh  European  Council  (December 1992)  confirmed  this[2],  stressing  the  importance  of
       codification as it offers certainty as to the law applicable to a given matter at a given time.

       Codification must be undertaken in full compliance with the normal Community legislative procedure.

       Given that no changes of substance may be made to the instruments affected by codification, the European Parliament, the Council  and  the
       Commission have agreed, by an interinstitutional agreement dated 20 December 1994, that an accelerated procedure may be used for the fast-
       track adoption of codification instruments.

4.    The purpose of this proposal is to undertake a codification of Council Directive 77/536/EEC of 28 June 1977 on  the  approximation  of  the
       laws of the Member States relating to the roll-over protection structures  of  wheeled  agricultural  or  forestry  tractors[3].  The  new
       Directive will supersede the various acts incorporated in it[4]; this proposal fully preserves the content of the acts being codified  and
       hence does no more than bring them together with only such formal amendments as are required by the codification exercise itself.

5.    The codification proposal was drawn up on the basis of a preliminary consolidation, in all official languages, of Directive 77/536/EEC  and
       the instruments amending it, carried out by the Office for Official Publications  of  the  European  Communities,  by  means  of  a  data-
       processing system. Where the Articles have been given new numbers, the correlation between the old and the new numbers is shown in a table
       contained in Annex XI to the codified Directive.

THE EUROPEAN PARLIAMENT AND THE COUNCIL OF THE EUROPEAN UNION,

Having regard to the Treaty establishing the European Community, and in particular Article Ö 95 Õ thereof,

Having regard to the proposal from the Commission,

Having regard to the opinion of the European Economic and Social Committee[5],

Acting in accordance with the procedure laid down in Article 251 of the Treaty[6],

Whereas:

                                            ê 

   1) Council Directive 77/536/EEC of 28 June 1977 on the approximation of the laws of the Member States relating  to  the  roll-over  protection
      structures of wheeled agricultural or forestry tractors[7] laid down technical prescriptions concerning  the  design  and  construction  of
      agricultural or forestry tractors as regards the roll-over protection structures. These technical prescriptions concerned the approximation
      of the laws of the Member States to allow for the EC type-approval procedure established by Directive 2003/37/EC of the European Parliament
      and of the Council of 26 May 2003 on type-approval  of  agricultural  or  forestry  tractors,  their  trailers  and  interchangeable  towed
      machinery, together with their systems, components and separate technical units and repealing Directive  74/150/EEC[8]  to  be  applied  in
      respect of each type of vehicle. Directive 77/536/EEC has been substantially amended several times[9]. In  the  interests  of  clarity  and
      rationality the said Directive should be codified.

   2) Ö This Directive is one of the separate Directives of the EC type-approval system provided for in Directive 2003/37/EC.  Consequently,  the
      provisions laid down in Directive 2003/37/EC relating to agricultural or  forestry  tractors,  their  trailers  and  interchangeable  towed
      machinery, together with their systems, components and separate technical units apply to this Directive. Õ

   3) This Directive should be without prejudice to the obligations of the Member States relating  to  the  time-limits  for  transposition  into
      national law and application of the Directives set out in Annex X, Part C,

                                            ê 77/536/EEC (adapted)

HAVE ADOPTED THIS DIRECTIVE:

                                                                    Article 1

1. Each Member State shall grant EC 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, II, III, IV and V hereto.

2. The Member State which has granted EC 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 2

Member States shall for each type of roll-over protection structure and its tractor attachment which they approve pursuant to  Article  1,  issue
to the manufacturer of the tractor or of the roll-over protection structure or to his authorised representative, an  EC  component  type-approval
mark conforming to the model shown in Annex VI hereto.

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 1 and other devices.

                                                                    Article 3

1. No Member State may prohibit the placing on the market of roll-over protection structures or their tractor attachment on grounds  relating  to
their construction if they bear the EC component type-approval mark.

2. Nevertheless, a Member State may prohibit the placing on the market of roll-over protection structures bearing the EC 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 4

The competent authorities of each Member State shall within one month send to the competent authorities of the other Member States 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.

1. If the Member State which has granted EC component type-approval finds that a number of roll-over  protection  structures  and  their  tractor
attachments bearing the same EC 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  EC
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 EC  component  type-approval  and
of the reasons for any such measure.

Any 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 decision 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.

No Member State may refuse to grant EC type-approval or national type-approval  in  respect  of  a  tractor  on  grounds  relating  to  roll-over
protection structures or their tractor attachments if these bear the EC component type-approval  mark  and  if  the  requirements  laid  down  in
Annex VIII have been satisfied.

No 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  EC  component  type-approval  mark  and  if  the  requirements  laid  down  in
Annex VIII have been met.

                                                    CONDITIONS FOR EC COMPONENT TYPE-APPROVAL

1.    DEFINITION

1.1.  A roll-over protection structure (safety cab or frame) means the structure on a tractor the essential purpose  of  which  is  to  avoid  or
       limit risks to the driver resulting from roll-over of the tractor during normal use.

1.2.  The structures mentioned in 1.1 are characterised by the fact that, in the event of roll-over, they ensure  an  unobstructed  space  inside
       them large enough to protect the driver.

2.    GENERAL REQUIREMENTS

2.1.  Every roll-over protection structure and its attachment to a tractor must be so  designed  and  constructed  as  to  fulfil  the  essential
       purpose laid down in 1.

2.2.  This requirement shall be checked by one of the two test methods described in Annex III. The  method  chosen  shall  take  account  of  the
       tractor mass as follows:

         – for tractors of mass specified by Article 9 — Annex III B,

         – for tractors of mass more than 1·5 tonnes and not more than 3·5 tonnes — Annex IIIA,

                                            ê 1999/55/EC Art. 1 and Annex point 1

         – as regards tractors with a reversible driving position (i.e. with a reversible seat and  steering  wheel)  or  fitted  with  optional
           seats, only the testing method described in part B of Annex III shall apply.

                                            ê 77/536/EEC (adapted)

3.    APPLICATION FOR EC COMPONENT TYPE-APPROVAL

3.1.  The application for EC component type-approval with regard to the strength of a roll-over protection structure  and  the  strength  of  its
       attachment to a tractor shall be submitted by the tractor manufacturer or by the manufacturer of the roll-over protection structure or  by

                                                                     ANNEX II

                    CONDITIONS FOR TESTING THE STRENGTH OF A ROLL-OVER PROTECTION STRUCTURE AND OF ITS ATTACHMENT TO A TRACTOR

1.    GENERAL REQUIREMENTS

1.1.  Test purposes

      Tests made using special rigs are intended to simulate such loads as are imposed  on  a  roll-over  protection  structure  when  a  tractor
       overturns. These tests, described in Annex III, must enable the strength of the roll-over protection structure and the attaching  brackets
       to the tractor to be assessed.

1.2.  Preparation for test

1.2.1.      A roll-over protection structure must be tested on a tractor of the type for which it  is  designed.  It  must  be  attached  to  the
       tractor in accordance with the instructions of the manufacturer of  the  tractor  and/or  those  of  the  manufacturer  of  the  roll-over
       protection structure.

1.2.2.      For the tests a tractor must be fitted with all structural components of the series production which may influence  the  strength  of
       the roll-over protection structure or which may be necessary for the strength test.

      Components which may create a hazard in the zone of clearance must also be fitted so that they may be examined as to their compliance  with
       the requirements of 4.1 of this Annex.

1.2.3.      Tests shall be made with the tractor stationary.

1.3.  Tractor mass

      The measured mass W used in the formulae (see Annex III A and III B) to calculate the height of the fall of the  pendulum  weight  and  the
       crushing force, shall be at least that defined in 2.4 of Annex  I  to  Directive  2003/37/EC  (i.e.  excluding  optional  accessories  but
       including coolant, oils, fuel, tools and driver) plus the roll-over protection structure and less 75 kg. Not included are  optional  front
       or rear ballast weights, tyre ballast, mounted implements, mounted equipment or any specialised components.

2.    APPARATUS AND EQUIPMENT

2.1.  Pendulum weight

2.1.1.      A pendulum weight shall be suspended by two chains or wire ropes from pivot points not less than 6 m above the  ground.  Means  shall
       be provided for adjusting independently the suspended height of the weight and the angle between the weight and the supporting  chains  or
       wire ropes.

2.1.2.      The weight shall be 2 000 ± 20 kg excluding the weight of the chains or wire ropes which themselves shall  not  exceed  100  kg.  The
       length of the sides of the impact face shall be 680 ± 20 mm (see Annex IV, fig. 4). The weight shall be filled in  such  a  way  that  the
       position of its centre of gravity is constant.

2.1.3.      Means shall be provided of pulling the weight back as a pendulum to a height which is  determined  for  each  test.  A  quick-release
       mechanism shall allow the weight to swing downwards without altering the tilt in relation to the supporting chains or wire ropes.

2.2.  Pendulum supports

      The pendulum pivot points shall be rigidly fixed so that their displacement in any direction does not exceed 1% of the height of fall.

2.3.  Lashings

2.3.1.      The tractor shall be lashed by means of restraining and tensioning devices  to  ground  rails  rigidly  attached  to  a  non-yielding
       concrete base. The rails shall be suitably spaced to enable the tractor to be lashed down as illustrated in Annex IV, figs. 5,  6  and  7.
       For each test the tractor wheels and any axle stands used shall rest on the non-yielding base.

2.3.2.      Apart from the tensioning devices and ground rail attachments the tractor shall be lashed down  with  wire  rope  of  the  dimensions
       specified.

      This wire rope shall be any round strand, fibre core, construction 6 × 19 in accordance with ISO 2408. The nominal rope diameter  shall  be
       13 mm.

2.3.3.      The central pivot of an articulated tractor shall be supported and lashed down as appropriate for the front, rear  and  side  impacts
       and for the crushing tests and shall, in addition, be propped from the side for the side impact. The front and rear wheels need not be  in
       line if this makes it more convenient to attach appropriate wire ropes.

2.4.  Wheel prop and beam

2.4.1.      A beam shall be used as a prop for the wheel in the side impact as shown in Annex IV, fig. 7.

2.4.2.      A softwood beam of approximately 150 mm square shall be clamped to the floor to brace the tyres on the side opposite  the  impact  as
       shown in Annex IV, figs. 5, 6 and 7.

2.5.  Props and lashings for articulated tractors

2.5.1.      Additional props and lashings shall be used for articulated tractors. Their purpose is to ensure that the section of the  tractor  on
       which the roll-over protection structure is fitted is as rigid as that of a rigid tractor.

2.5.2.      Additional specific details are given in Annex III for the impact and crushing tests.

2.6.  Crushing rig

      A rig as shown in Annex IV, fig. 8, shall be capable of exerting a downward force on a roll-over protection structure through a rigid  beam
       approximately 250 mm wide connected to the load-applying mechanism by means of universal joints. Suitable axle stands shall be provided so
       that the tractor tyres do not bear crushing force.

2.7.  Measuring apparatus

2.7.1.      For the tests laid down in Annex III A and III B a device must be used on which a moving friction  collar  is  tightly  fitted  on  a
       horizontal rod for the purpose of measuring the difference between maximum momentary deflection and  residual  deflection  during  a  side
       impact test.

2.7.2.      For the tests laid down in Annex III A, measurements shall be made after the laboratory test to determine whether  any  part  of  the
       protection structure has entered the zone of clearance prescribed in 2 of Annex III A.

2.7.3.      For the tests laid down in Annex III B, equipment must be provided — which may include photographic equipment —  so  that  after  the
       laboratory tests it may be established whether any part of the protection structure has, during these tests, entered or come into  contact
       with the zone of clearance prescribed in 2 of Annex III B.

2.8.  Measurement tolerances

      The following tolerances shall apply to measurements made during the tests:

2.8.1.      linear dimensions measured during test (except 2.8.2); protection structure and  tractor  dimensions,  zone  of  clearance  and  tyre
       deflections when lashed for impact tests: ± 3 mm;

2.8.2.      height of pendulum weight set for impact tests: ± 6 mm;

2.8.3.      measured tractor mass: ± 20 kg;

2.8.4.      load applied in crushing tests: ± 2%;

2.8.5.      angle of weight-supporting chains or wire ropes at the point of impact: ± 2°.

3.    TESTS

3.1.1.2.    If, during the test, any part of the restraining equipment moves or breaks, the test shall be repeated.

3.1.1.3.    No repairs or adjustments to the tractor or roll-over protection structure may be carried out during the test.

3.1.1.4.    The tractor gear-box shall be in neutral and the brakes off throughout the test.

                                            ê 1999/55/EC Art. 1 and Annex point 2

3.1.1.5.    In the case of a tractor with a reversible driving position (i.e. with a reversible seat and steering wheel), the first impact  shall
       be longitudinal and shall be applied at the heaviest extremity (with more than 50% of the mass of the tractor). It shall be followed by  a
       crushing test at the same extremity. The second impact shall be on the lightest extremity, and the third impact shall be  from  the  side.
       Lastly, a second crushing test shall be carried out on the lightest extremity.

                                            ê 77/536/EEC

3.1.2.      Track width

      A track width setting for the rear wheels shall be chosen such that as far as possible the roll-over protection structure is not  supported
       by the tyres during the tests.

3.1.3.      Removal of non-hazard-creating components

      All components of the tractor and roll-over protection structure  which,  as  complete  units,  constitute  protection  for  the  driver  —
       including weather protection — shall be supplied with the tractor to be tested. It is permissible to remove front, side and  rear  windows
       of safety glass or similar material and any detachable panels, fittings and accessories which have no function of structural strength  and
       which cannot create a hazard in the event of overturning.

3.1.4.      Direction of impacts

      The side of the tractor on which the side impact is struck shall be that which is likely to give the greatest distortion. The  rear  impact
       shall be on the corner furthest from the side impact, and the front impact on the corner nearest the side impact.

3.1.5.      Tyre pressures and deflections

      Tyres shall not be water ballasted. Pressures and deflections in those tyres which are lashed in the various tests shall be  in  accordance

                                                                A — TEST METHOD I

1.    IMPACT AND CRUSHING TESTS

1.1.  Impact at the rear

1.1.1.      The tractor shall be so placed in relation to the weight that the weight will strike the  roll-over  protection  structure  when  the
       impact face of the weight and the supporting chains or wire ropes are at an angle of 20° to the vertical unless the  roll-over  protection
       structure at the point of contact has, during deflection, a greater angle to the vertical. In this case the  impact  face  of  the  weight
       shall be adjusted by means of an additional support so that it is parallel to the roll-over protection structure at the point of impact at
       the moment of maximum deflection, the supporting chains or wire ropes remaining at an angle of 20° to the vertical. Steps must be taken to
       reduce the tendency of the weight to turn about the point of contact. The suspended height of the weight shall be  so  adjusted  that  the
       locus of its centre of gravity passes through the point of contact.

      The point of impact shall be that part of the roll-over 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 weight shall be one-sixth of the width of the top  of  the
       roll-over protection structure inwards from a vertical plane parallel to the median plane of the tractor touching the outside extremity of
       the top of the roll-over protection structure.

      However, if a curve in the back of the roll-over protection structure starts at a greater distance than this inside  this  vertical  plane,
       the impact shall be administered at the beginning of the curve, i.e. at the point where this curve is tangential to a line at right angles
       to the median plane of the tractor (see Annex IV, fig. 9).

      If a protruding member would present an inadequate area for the weight, a steel plate of appropriate thickness and depth and about  300  mm
       in length shall be fastened to that member in such a manner that the strength of the roll-over protection structure is not affected.

1.1.2.      Tractors with rigid bodies shall be lashed down. The points of attachment of the lashings shall be approximately 2 m behind the  rear
       axle and 1·5 m in front of the front axle. They shall either be in the plane in which the centre of gravity of the pendulum will swing  or
       more than one lashing shall give a resultant force in this plane, as in Annex IV, fig. 5.

      The lashings shall be tightened so that the deflections in the front and rear tyres are as  indicated  in  3.1.5  of  Annex  II.  When  the
       lashings have been tightened, a wooden beam 150 mm square shall be clamped in front of the rear wheels and driven tight against them.

1.1.3.      Articulated tractors shall have both axles lashed down. The axle of that section of the tractor on  which  the  roll-over  protection
       structure is mounted shall be treated as the rear axle in Annex IV, fig. 5. The point of articulation will then be supported by a beam 100
       mm square and will be lashed down firmly by means of wire ropes attached to the ground rails.

1.1.4.      The weight shall be pulled back so that the height of its centre of gravity above that at  the  point  of  impact  is  given  by  the
       formula:

                                                                H = 125 + 0·020 W

      where H is the height of fall in millimetres and W the mass of the tractor as defined in 1.3 of Annex II.

      The weight shall then be released and allowed to crash against the roll-over protection structure.

1.2.  Impact at the front

1.2.1.      The tractor shall be so placed in relation to the weight that the weight will strike the  roll-over  protection  structure  when  the
       impact face of the weight and the supporting chains or wire ropes are at an angle of 20° to the vertical unless the  roll-over  protection
       structure at the point of contact has, during deflection, a greater angle to the vertical. In this case the  impact  face  of  the  weight
       shall be adjusted by means of an additional support so that it is parallel to the roll-over protection structure at the point of impact at
       the moment of maximum deflection, the supporting chains or wire ropes remaining at an angle of 20° to the vertical. Steps must be taken to
       reduce the tendency of the weight to turn about the point of contact. The suspended height of the weight shall be  so  adjusted  that  the
       locus of its centre of gravity passes through the point of contact.

      The point of impact shall be that part of the roll-over protection structure likely to hit the  ground  first  if  the  tractor  overturned
       sideways whilst travelling forward, normally the top front corner. The position of the centre of gravity of the weight shall be  not  more
       than 80 mm from a vertical plane parallel to the median plane of the tractor touching the outside extremity of the top  of  the  roll-over
       protection structure.

      However, if a curve in the front of the roll-over protection structure starts at a greater distance than 80 mm inside this vertical  plane,
       the impact shall be administered at the beginning of the curve, i.e. at the point where this curve is tangential to a line at right angles
       to the median plane of the tractor (see Annex IV, fig. 9).

1.2.2.      Tractors with rigid bodies shall be lashed down as indicated in Annex IV, fig. 6. The points of attachment of the lashings  shall  be
       approximately 2 m behind the rear axle and 1·5 m in front of the front axle.

      The lashings shall be tightened so that the deflections in the front and rear tyres are as  indicated  in  3.1.5  of  Annex  II.  When  the
       lashings have been tightened, a wooden beam approximately 150 mm square shall be clamped behind the rear wheels and driven  tight  against
       them.

1.2.3.      Articulated tractors shall have both axles lashed down. The axle of that section of the tractor on  which  the  roll-over  protection
       structure is mounted shall be treated as the front axle in Annex IV, fig. 6. The point of articulation shall then be supported by  a  beam
       approximately 100 mm square and shall be lashed down firmly by means of wire ropes attached to the ground rails.

1.2.4.      The weight shall be pulled back so that the height of its centre of gravity above that at  the  point  of  impact  is  given  by  the
       formula:

                                                                H = 125 + 0·020 W.

1.3.  Impact at the side

1.3.1.      The tractor shall be so placed in relation to the weight that the weight will strike the  roll-over  protection  structure  when  the
       impact face of the weight and the supporting chains or wire ropes are vertical unless the protection structure at the point of contact is,
       during deflection, other than vertical. In this case the impact face of the weight 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. The suspended height of the weight shall be so adjusted that the locus of its centre of gravity  passes  through
       the point of contact.

      The point of impact shall be that part of the roll-over 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 of the tractor and passing through the middle of the seat at  the  mid-point  of
       adjustment. Steps must be taken to reduce the tendency of the weight to turn about the point of contact.

1.3.2.      For rigid tractors, any axle the position of which is rigid relative to the protection structure shall be lashed down on the side  on
       which the impact is to be administered. In the case of a two-wheel drive tractor this will normally be the rear axle; this arrangement  is
       shown in Annex IV, fig. 7. The two lashings shall pass over the axle from points directly below it, one passing to a point  of  attachment
       approximately 1·5 m in front of the axle and the other to a point approximately 1·5 m behind the axle. The lashings shall be tightened  so
       that there is a deflection in the tyre adjacent to the lashing as indicated in 3.1.5 of Annex II. After lashing, a wooden  beam  shall  be
       placed as a prop against the wheel opposite the weight and secured to the floor so that it is held tightly against the  wheel  rim  during
       impact as shown in Annex IV, fig. 7. The length of the beam shall be chosen so that when in position against the wheel it is at  an  angle
       of 30 ± 3° to the horizontal. Its length shall be 20 to 25 times its thickness and its width two to three times its thickness. Both  axles
       shall be prevented from moving sideways by means of a beam clamped to the floor against the outside of the wheel on the side opposite that
       on which the impact is to be administered.

1.3.3.      An articulated tractor must be lashed down so that the section of the tractor bearing the protection structure is  fixed  rigidly  to
       the ground as in the case of a non-articulated tractor.

      Both axles of articulated tractors shall be lashed to the ground. The axle and  wheels  of  that  section  of  the  tractor  on  which  the
       protection structure is mounted shall be lashed and propped as in Annex IV, fig. 7. The point of articulation shall be supported by a beam
       at least 100 mm square and lashed down to the ground rails. A prop will be positioned against the point of articulation and secured to the
       floor so that it has the same effect as a prop against the rear wheel and provides support similar to that achieved for a rigid tractor.

1.3.4.      The weight shall be pulled back so that the height of its centre of gravity above that at  the  point  of  impact  is  given  by  the
       formula:

                                                                H = 125 + 0·150 W.

1.4.  Crushing at the rear

      The tractor shall be positioned in the rig described in 2.6 of Annex II and shown in Annex IV, figs. 8 and 10, in such a way that the  rear
       edge of the beam is over the rearmost top load-bearing part of the protection structure and the median longitudinal plane of  the  tractor
       is midway between the points of application of force to the beam.

      The axle stands shall be placed under the axles in such a way that the tyres do not bear  the  crushing  force.  The  force  applied  shall
       correspond to twice the mass of the tractor as defined in 1.3 of Annex II. It may be necessary to lash down the front of the tractor.

1.5.  Crushing at the front

1.5.1.      This shall be identical to the crushing test at the rear except that the front edge of the beam shall be over the frontmost top  part
       of the roll-over protection structure.

1.5.2.      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 roll-over protection structure with that part of the  front  of
       the tractor capable of supporting the tractor's mass when overturned. The force shall then be removed and  the  tractor  re-positioned  so
       that the beam is over that point of the protection structure which would then support the rear of the tractor when completely  overturned,
       as shown in Annex IV, fig. 10, and the full force reapplied.

2.    ZONE OF CLEARANCE

2.1.  The “zone of clearance” is defined by planes as follows, the tractor being on a horizontal surface:

         – horizontal, 95 cm above the compressed seat,

         – vertical, perpendicular to the median plane of the tractor and 10 cm behind the back of the seat,

         – vertical, parallel to the median plane of the tractor and 25 cm to the left of the centre of the seat,

         – vertical, parallel to the median plane of the tractor and 25 cm to the right of the centre of the seat,

         – an inclined plane in which lies a horizontal line which is at right angles to the median plane  of  the  tractor,  95  cm  above  the
           compressed seat and 45 cm (plus the normal fore and aft movement of the seat) in front of the back of the seat. This  inclined  plane
           passes in front of the steering wheel and at its nearest point is 4 cm from the rim of the steering wheel.

2.2.  The back of the seat shall be determined ignoring any padding thereon. The seat shall be in  its  rearmost  adjustment  for  normal  seated
       operation of the tractor and in its highest position if this is independently variable. Where the suspension of the seat is adjustable  it
       shall be at its mean setting and the load on it shall be 75 kg.

3.    MEASUREMENTS TO BE MADE

3.1.  Fractures and cracks

      After each test all structural members, joints and attaching brackets on the tractor shall be visually examined for  fractures  or  cracks,
       any small cracks in unimportant parts being ignored.

3.2.  Zone of clearance

3.2.1.      After each test the roll-over protection structure shall be examined to see whether any part of the protection structure has  entered
       a zone of clearance round the driving seat as defined in 2.

3.2.2.      In addition, the protection structure shall be examined 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 structure if any  part
       of it would have come in contact with flat ground if the tractor had overturned towards the direction from which the impact came. For this
       purpose the tyre and track setting shall be assumed to be the smallest indicated by the manufacturer.

3.3.  Maximum momentary deflection

      During the side impact test the difference between the maximum momentary deflection and the residual deflection  at  a  height  of  950  mm
       above the loaded seat shall be recorded. One end of the rod described in 2.7.1 of Annex II shall be attached to the upper part of the roll-
       over protection structure and the other end passed through a hole in the vertical standard. The position of the friction collar on the rod
       after the impact indicates the maximum momentary deflection.

3.4.  Permanent deflection

      After the final compression test the permanent deflection of the protection structure shall be  recorded.  For  this  purpose,  before  the
       start of the test, the positions of the main roll-over protection structure members in relation to the seat shall be recorded.

                                                                B — TEST METHOD II

1.    IMPACT AND CRUSHING TESTS

1.1.  Impact at the rear

1.1.1.      The tractor shall be so placed in relation to the weight that the weight will strike the  roll-over  protection  structure  when  the
       impact face of the weight and the supporting chains or wire ropes are at an angle of 20° to the vertical unless the  roll-over  protection
       structure at the point of contact has, during deflection, a greater angle to the vertical. In this case the  impact  face  of  the  weight
       shall be adjusted by means of an additional support so that it is parallel to the roll-over protection structure at the point of impact at
       the moment of maximum deflection, the supporting chains or wire ropes remaining at an angle of 20° to the vertical. Steps must be taken to
       reduce the tendency of the weight to turn about the point of contact. The suspended height of the weight shall be  so  adjusted  that  the
       locus of its centre of gravity passes through the point of contact.

      The point of impact shall be that part of the roll-over 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 weight shall be one-sixth of the width of the top  of  the
       roll-over protection structure inwards from a vertical plane parallel to the median plane of the tractor touching the outside extremity of
       the top of the roll-over protection structure.

      However, if a curve in the back of the roll-over protection structure starts at a greater distance than this inside  this  vertical  plane,
       the impact shall be administered at the beginning of the curve, i.e. at the point where this curve is tangential to a line at right angles
       to the median plane of the tractor (see Annex IV, fig. 9).

      If a protruding member would present an inadequate area for the weight, a steel plate of appropriate thickness and depth and about  300  mm
       in length shall be fastened to that member in such a manner that the strength of the roll-over protection structure is not affected.

1.1.2.      Tractors with rigid bodies shall be lashed down. The points of attachment of the lashings shall be approximately 2 m behind the  rear
       axle and 1·5 m in front of the front axle. They shall either be in the plane in which the centre of gravity of the pendulum will swing  or
       more than one lashing shall give a resultant force in this plane, as in Annex IV, fig. 5.

      The lashing shall be tightened so that the deflections in the front and rear tyres are as  indicated  in  3.1.5  of  Annex  II.  After  the
       lashings have been tightened a wooden beam 150 mm square shall be clamped in front of the rear wheels and driven tight against them.

1.1.3.      Articulated tractors shall have both axles lashed down. The axle for that section of the tractor on which  the  roll-over  protection
       structure is mounted shall be treated as the rear axle in Annex IV, fig. 5. The point of articulation will then be supported by a beam 100
       mm square minimum and will be lashed down firmly by means of wire ropes attached to the ground rails.

1.1.4.      The weight shall be pulled back so that the height of its centre of gravity above that at  the  point  of  impact  is  given  by  the
       formula:

                                                  H = 2·165 × 10−8 × WL2 or H = 5·73 × 10−2 × I

      where:

       H    =     the height of fall in millimetres,

       W    =     the mass of the tractor as defined in 1.3 of Annex II,

       L    =     the maximum tractor wheelbase in millimetres,

       I    =     the moment of inertia of the rear axle, with wheels removed, in kilograms per square metre (kg/m2).

      The weight shall then be released and allowed to crash against the roll-over protection structure.

1.1.5.      There shall be no rear impact in the case of a tractor at least 50 % of the mass of which, as defined in 1.3 of Annex  II,  bears  on
       the front axle.

1.2.  Impact at the front

1.2.1.      The tractor shall be so placed in relation to the weight that the weight will strike the  roll-over  protection  structure  when  the
       impact face of the weight and the supporting chains or wire ropes are at an angle of 20° to the vertical unless the  roll-over  protection
       structure at the point of contact has, during deflection, a greater angle to the vertical. In this case the  impact  face  of  the  weight
       shall be adjusted by means of an additional support so that it is parallel to the roll-over protection structure at the point of impact at
       the moment of maximum deflection, the supporting chains or wire ropes remaining at an angle of 20° to the vertical. Steps must be taken to
       reduce the tendency of the weight to turn about the point of contact. The suspended height of the weight shall be  so  adjusted  that  the
       locus of its centre of gravity passes through 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  overturned  sideways
       whilst travelling forward, normally the top front corner. The position of the centre of gravity of the weight shall be not more than 80 mm
       from a vertical plane parallel to the median plane of the tractor touching the outside extremity of the top of  the  roll-over  protection
       structure.

      However, if a curve in the front of the roll-over protection structure starts at a greater distance than 80 mm inside this vertical  plane,
       the impact shall be administered at the beginning of the curve, i.e. at the point where this curve is tangential to a line at right angles
       to the median plane of the tractor (see Annex IV, fig. 9).

1.2.2.      Tractors with rigid bodies shall be lashed down as illustrated in Annex IV, fig. 6. The points of attachment of  the  lashings  shall
       be approximately 2 m behind the rear axle and 1·5 m in front of the front axle.

      The lashings shall be tightened so that the deflections in the front and rear tyres are as  indicated  in  3.1.5  of  Annex  II.  When  the
       lashings have been tightened, a wooden beam 150 mm square shall be clamped behind the rear wheels and driven tight against them.

1.2.3.      Articulated tractors shall have both axles lashed down. The axle of that section of the tractor on  which  the  roll-over  protection
       structure is mounted shall be treated as the front axle in Annex IV, fig. 6. The point of articulation shall then be supported by  a  beam
       100 mm square minimum and shall be lashed down firmly by means of wire ropes attached to the ground rails.

1.2.4.      The weight shall be pulled back so that the height of its centre of gravity above that at  the  point  of  impact  is  given  by  the
       formula:

                                                                H = 125 + 0·020 W.

1.3.  Impact at the side

1.3.1.      The tractor shall be so placed in relation to the weight that the weight will strike the  roll-over  protection  structure  when  the
       impact face of the weight and the supporting chains or wire ropes are vertical unless the protection structure at the point of contact is,
       during deflection, other than vertical. In this case the impact face of the weight 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. The suspended height of the weight shall be so adjusted that the locus of its centre of gravity  passes  through
       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 of the tractor and passing through the middle of the seat at the  mid-point  of  adjustment.
       Steps must be taken to reduce the tendency of the weight to turn about the point of contact. è1 In the case of a tractor with a reversible
       driving position (i.e. with a reversible seat and steering wheel), the point of impact shall be determined in relation to the intersection
       of the median plane of the tractor and of a plane perpendicular to it, by a straight line passing through a point that is equidistant from
       the two seat reference points. ç

1.3.2.      For rigid tractors, any axle the position of which is rigid relative to the protection structure shall be lashed down on the side  on
       which the impact is to be administered. In the case of a two-wheel drive tractor this will normally be the rear axle; this arrangement  is
       shown in Annex IV, fig. 7. The two lashings shall pass over the axle from points directly below it, one passing to a point  of  attachment
       approximately 1·5 m in front of the axle and the other to a point approximately 1·5 m behind the axle. The lashings shall be tightened  so
       that there is a deflection in the tyre adjacent to the lashing as indicated in 3.1.5 of Annex II. After lashing, a wooden  beam  shall  be
       placed as a prop against the wheel opposite the weight and secured to the floor so that it is held tightly against the  wheel  rim  during
       impact as shown in Annex IV, fig. 7. The length of the beam shall be chosen so that when in position against the wheel it is at  an  angle
       of 30 ± 3° to the horizontal. Its length shall be 20 to 25 times its thickness and its width two to three times its thickness. Both  axles
       shall be prevented from moving sideways by means of a beam clamped to the floor against the outside of the wheel on the side opposite that
       on which the impact is to be administered.

1.3.3.      An articulated tractor must be lashed down so that the section of the tractor bearing the protection structure is  fixed  rigidly  to
       the ground as in the case of a non-articulated tractor.

      Both axles of articulated tractors shall be lashed to the ground. The axle and  wheels  of  that  section  of  the  tractor  on  which  the
       protection structure is mounted shall be lashed and propped as in Annex IV, fig. 7. The point of articulation shall be supported by a beam
       at least 100 mm square and lashed down to the ground rails. A prop will be positioned against the point of articulation and secured to the
       floor so that it has the same effect as a prop against the rear wheel and provides support similar to that achieved for a rigid tractor.

1.3.4.      The weight shall be pulled back so that the height of its centre of gravity above that at  the  point  of  impact  is  given  by  the
       formula:

                                                                H = 125 + 0·150 W.

1.4.  Crushing at the rear

      The tractor shall be positioned in the rig described in 2.6 of Annex II and shown in Annex IV, figs. 8 and 10 in such a way that  the  rear
       edge of the beam is over the rearmost top load-bearing part of the roll-over protection structure and the median longitudinal plane of the
       tractor is midway between the points of application of force to the beam.

      The axle stands shall be placed under the axles in such a way that the tyres do not bear  the  crushing  force.  The  force  applied  shall
       correspond to twice the mass of the tractor as defined in 1.3 of Annex II. It may be necessary to lash down the front of the tractor.

1.5.  Crushing at the front

1.5.1.      This test shall be identical to the crushing test at the rear except that the front edge of the beam shall be over the frontmost  top
       part of the roll-over protection structure.

1.5.2.      Where the front part of the roll-over protection structure roof cannot 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 roll-over protection structure with that part of  the
       front of the tractor capable of supporting the tractor's mass when overturned. The force  shall  then  be  removed  and  the  tractor  re-
       positioned so that the beam is over that point of the roll-over protection structure which would then support the rear of the tractor when
       completely over-turned as shown in Annex IV, fig. 10, and the full force reapplied.

2.    ZONE OF CLEARANCE

2.1.  The zone of clearance is illustrated in Annex IV, fig. 3, and is defined in relation to a vertical reference plane  generally  longitudinal
       to the tractor and passing through a seat reference point, described in 2.3, and the centre of the steering  wheel.  The  reference  plane
       shall be assumed to move horizontally with the seat and steering wheel during impacts but to remain perpendicular  to  the  floor  of  the
       tractor or of the roll-over protection structure if this is resiliently mounted.

      Where the steering wheel is adjustable, its position should be that for normal seated driving.

2.2.  The boundaries of the zone shall be taken as:

2.2.1.      vertical planes 250 mm on either side of the reference plane extending upwards from the seat reference point for 300 mm;

2.2.2.      parallel planes extending from the upper edge of planes 2.2.1 to a maximum height of 900  mm  above  the  seat  reference  point  and
       inclined in such a way that the upper edge of the plane on the side from which the side impact is struck is  at  least  100  mm  from  the
       reference plane;

2.2.3.      a horizontal plane 900 mm above the seat reference point;

2.2.4.      an inclined plane perpendicular to the reference plane and including a point 900 mm directly above the seat reference point  and  the
       rearmost point of the seat structure including its suspension;

2.2.5.      a vertical plane perpendicular to the reference plane extending downwards from the rear-most point of the seat;

2.2.6.      a curvilinear surface, perpendicular to the reference plane, with a radius of 120 mm tangential to planes 2.2.3 and 2.2.4;

2.2.7.      a curvilinear surface, perpendicular to the reference plane, having a radius of 900 mm and extending forward  for  400  mm  from  and
       tangential to plane 2.2.3 at a point 150 mm forward of the seat reference point;

2.2.8.      an inclined plane perpendicular to the reference plane, joining surface 2.2.7 at  its  forward  edge  and  passing  40  mm  from  the
       steering wheel. In the case of a high steering wheel position this plane is replaced by a tangent plane to surface 2.2.7;

2.2.9.      a vertical plane, perpendicular to the reference plane, 40 mm forward of the steering wheel;

2.2.10.     a horizontal plane through the seat reference point;

                                            ê 1999/55/EC Art. 1 and Annex point 3(b)

2.2.11.     in the case of a tractor with a reversible driving position (i.e. with a reversible seat and steering wheel), the clearance shall  be
       a combination of the two clearances determined by the two positions of the steering wheel and seat;

2.2.12.     in the case of a tractor which can be fitted with optional seats, the tests shall be based on the  combined  clearance  of  the  seat
       reference points for all available seat-fitting options. The roll-over protection structure must not enter the combined  clearance  around
       the various seat reference points;

2.2.13.     where a new option for the seat is proposed after the test has taken place, a calculation is made to determine whether the  clearance
       around the new seat reference point is located entirely within the combined clearance established previously. If this is not the  case,  a
       new test is required.

                                            ê 77/536/EEC

2.3.  Seat location and seat reference point

2.3.1.      For the purpose of defining the zone of clearance in 2.1, the seat shall be at  the  rearmost  point  of  any  horizontal  adjustment
       range. It shall be set at the mid-point of the vertical adjustment range where  this  is  independent  of  adjustment  of  its  horizontal
       position.

      The reference point shall be established using the apparatus illustrated in Annex IV, figs. 1  and  2,  to  simulate  loading  by  a  human
       occupant. 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.

2.3.2.      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.

2.3.3.      Where a seat suspension is provided with adjustment for the weight of the driver, this shall be set so that the seat is at  the  mid-
       point of its dynamic range.

      The apparatus shall be positioned on the seat. It shall then be loaded with a force of 550 N at a point 50 mm in front of  joint  (A),  and
       the two parts of the backrest board shall be lightly pressed tangentially against the backrest.

2.3.4.      If it is not possible to determine definite tangents to each area of the backrest (above and below the lumbar region)  the  following
       should be done:

2.3.4.1.    where no definite tangent to the lower area is possible: the lower part of  the  backrest  board  is  pressed  against  the  backrest
       vertically;

2.3.4.2.    where no definite tangent to the upper area is possible: the joint (B) is fixed at a height  of  230  mm  above  the  seat  reference
       point, if the lower part of the backrest board is vertical. Then the two parts of the backrest  board  are  lightly  pressed  against  the
       backrest tangentially.

3.    MEASUREMENTS TO BE MADE

3.1.  Fractures and cracks

      After each test all structural members, joints and attaching brackets on the tractor shall be visually examined for  fractures  or  cracks,
       any small cracks in unimportant parts being ignored.

3.2.  Zone of clearance

3.2.1.      During each test the roll-over protection structure shall be examined to see whether any part of the roll-over  protection  structure
       has entered a zone of clearance round the driving seat as defined in 2.1 and 2.2.

3.2.2.      In addition, the roll-over protection structure shall be examined to determine whether any part of the zone of clearance  is  outside
       the protection of the roll-over 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 in contact with  flat  ground  if  the  tractor  had  overturned  towards  the
       direction from which the impact came. For this purpose the tyre and track setting shall be assumed to be the  smallest  specified  by  the
       manufacturer.

3.3.  Maximum momentary deflection

      During the side impact test the difference between the maximum momentary deflection and the residual deflection  at  a  height  of  900  mm
       above and 150 mm forward of the seat reference point shall be recorded. One end of the rod  described  in  2.7.1  of  Annex  II  shall  be
       attached to the upper part of the roll-over protection structure and the other end passed through a hole in  the  vertical  standard.  The
       position of the friction collar on the rod after the blow indicates the maximum momentary deflection.

3.4.  Permanent deflection

      After the final compression 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 roll-over protection structure members in relation  to  the  seat  reference  point  shall  be
       recorded.

                                                                   ____________

                                                         CONDITIONS FOR EC TYPE-APPROVAL

1.    The application for EC type-approval of a tractor, with regard to the strength of a roll-over protection structure and the strength of  its
       attachment to the tractor shall be submitted by the tractor manufacturer or by his authorised representative.

2.    A tractor representative of the tractor type to be approved, on which a  protection  structure  and  its  attachment,  duly  approved,  are
       mounted, shall be submitted to the technical services responsible for conducting the type-approval tests.

3.    The technical service responsible for conducting the type-approval tests shall check whether the approved type of protection  structure  is
       intended to be mounted on the type of tractor for which the type-approval is  requested.  In  particular,  it  shall  ascertain  that  the
       attachment of the protection structure corresponds to that which was tested when the EC component type-approval was granted.

4.    The holder of the EC type-approval may ask for its extension for other types of protection structures.

5.    The competent authorities shall grant such extension on the following conditions:

5.1.  the new type of roll-over protection structure and its tractor attachment have received EC component type-approval;

5.2.  it is designed to be mounted on the type of tractor for which the extension of the EC type-approval is requested;

5.3.  the attachment of the protection structure to the tractor corresponds to  that  which  was  tested  when  EC  component  type-approval  was
       granted.

6.    A certificate, of which a model is shown in Annex IX, shall be annexed to the EC type-approval certificate for each type-approval or  type-
       approval extension which has been granted or refused.

7.    If the application for EC type-approval for a type of tractor is introduced at the same time as the request for EC component  type-approval
       for a type of roll-over protection structure intended to be mounted on the type of tractor for which EC type-approval  is  requested,  the
       checks laid down in 2 and 3 will not be made.

                                                                   ____________
