General
The Community type-approval procedure for wheeled agricultural or
forestry tractors covered by Council Directive 7 4/15O/EEC of 4 March
1974 ( l ) also includes roll-over protective structures ( safety cabs and
frames ). Ch a proposal from the Commission the Council adopted on
28 June 1977 a Directive on this subject , covering more specifically
the requirements , based on dynamic tests ( pendulum tests ), for testing
the strength of safety cabs or frames and their attachment to the
tractor ( 2 ). This Directive is based on the standardized testing codes
for agricultural tractors adopted by the Organization for Economic
Cooperation and Development in 1970 and 1973#        It emerged during the
preparation of this Directive that there were several gaps in both of
these codes which , in particular , did not enable light tractors
(mass less than l»5"t ) and heavy tractors ( mass greater than 4*5"t ) "to
be tested.      However , owing to recent advances in technology there is
a marked trend towards the production and therefore use of heavy tractors .
It is therefore essential also to be able to test the protective structu­
res of such tractors by means of a common inspection procedure in order
to facilitate ( a ) the increased trade in tractors of this type and (b )
also to provide the users of heavy tractors with satisfactory safety in
the event of tractor roll-over .      The Commission therefore made a group
of researchers responsible for preparing draft test requirements which
could reproduce as faithfully as possible actual roll-over conditions .
The surveys carried out have shown that the dynamic tests were not
adapted to tractors having a mass        of more than 4»5"t since , despite the
very precise specifications as regards the attachment of the tractor
to the ground during the test , the proportion of the nominal energy
absorbed by the ROPS can vary widely during tests as a result of
 ( 1 ) OJ     L 84, 28 March 1974, p.10
 ( 2 ) QJ ÏT° L220, 29 August 1977 » P-l
 ---pagebreak---                                       - 2 -
differing uncontrollable variables .    On the other hand static tests
enable a significant number of these drawbacks to be eliminated since
the forces and deflections can be recorded constantly during the loading
tests .  In case of doubt it is possible to interrupt the test in order
to observe more closely the process of deformation or crack formation ,
for example .
It can be concluded that the test conditions as envisaged in the annex
to this proposal for a directive represent fairly closely what happens in
reality , thus enabling structures not guarenteeing a sufficiently high
level of safety to be eliminated or in other words structures which show
excessive breakage and cracking during tests ,    or structures which include
 into the clearance zone    under the effect of the load , i.e. into the zone
 around the driving seat which the structure must be able to protect in
 the event of an accident .
 The static tests can be carried out on all types of tractors having a
 mass of more than 1.5 "t . They are not suitable for light tractors ( and
 in particular vineyeard or orchard tractors ) which are still in the
 process of harmonization .   The drawing-up of a test code for tractors
 of this type raises considerable difficulties owing to their highly
 specialized structure and conditions of use (need, for example , to be
 able to remove the roll-over hoop ).
 In contrast the static tests are also suitable for the range of tractors
 falling within the scope of the Council Directive of 28 June 1977 relating
 to dynamic strength testing , i.e. tractors having a mass of 1.5 - 4«5 "t *
 It ought therefore to have been possible to envisage the repeal of this
 directive , but on reflection such a measure involves several drawbacks .
 Owing to the existence of the CECD codes for several years the manufactures
 have in their possession equipment which is suitable for dynamic tests to
 meet the needs of prior inspection at the design stage of structures ,
 followed by the checks for conformity with an approved type .
 ---pagebreak---                                       - 3 -
These tests , at least at the present state of the art , can to a great
extent "be considered as equivalent to the static tests for the range
of tractors having a mass of 1.5 - 4*5        Requiring manufacturers to
acquire extremely costly equipment in order to be able to inspect
 structures on the basis of static tests is unjustifiable .   It is
therefore proposed that for this range of tractors a choice of test
method ( dynamic or static ) to which the structure will be submitted
during the type-approval tests be left to the manufacturers#
In the long term , however , it will doubtless be advisable to leave just
the static tests since these have the certain advantage of being able
to check a very wide range of safety cabs and frames with one single
installation#   It is thus foreseeable that the development of testing
techniques xfill first of all involve static tests .   Their accuracy will
in consequence certainly become greater than that of dynamic tests , so that
the two types of test will no longer be able to be considered as
equivalent in reproducing the consequences of an actual accident .
It must also not be forgotten that static testing technology is in its
infancy and that experience is currently limited to that acquired during
the research and experimental phase .    In other words there is a lack of
practical exprience which is only acquired during the general application
of a regulation and which enables any gaps and inaccuracies in a testing
code to be pinpointed .   It is however net possible to establish here and
now from what date the dynamic tests should be abandoned .    It is therefore
proposed that this decision be postponed and be taken at the appropriate
time via the procedure known as the Committee on the Adaptation to Technical
Progress , which was introduced by the Directive on the type-approval of
wheeled agricultural or forestry tractors .
It is proposed that only the static test be applicable to tractors having
a mass of more than 4»5 "t .  Such tractors would in addition also be
 required to be fitted with a ROPS in order to be eligible for EEC
type-approval .   This condition has already been imposed on tractors
 having a mass of 1.5 - 4*5 t by the Council Directive of 28 June 1977 *
 ---pagebreak---                                          -4-
     Apart from the obvious beneficial effect of this directive in diminishing
     the effects of an accident it can be stated that it would also have a
     favourable economic impact .   The intensive mechanization of agriculture
     and the trend towards heavier tractors with a view to work rationalization
     makes the approximation of laws particularly necessary and urgent •• The
     principle of mutual recognition of inspections saves manufacturers in the
     Member States work and above all considerably reduces expenditure by
     avoiding the repetition of destructive tests which are particularly costly#
II . Comments on the articles
     Article 1-6 introduce the EEC type-approval procedure for ROPS .   The aim
     of the directive is the free circulation of such items of equipment
     within the Community by prohibiting the Member States from opposing their
     marketing if they meet the structural and testing requirements laid down
     in the annexes and if they bear the EEC type-approval mark , a model of
     which is contained in Annex VI •   This procedure provides for a system of
     mutual information on all type-approvals issued , refused and withdrawn .
     The application for EEC type-approval can be filed either by the manufac­
     turer of the equipment    or by the manufacturer of the tractor .
     Article 7 incorporates the requirements relating to ROPS into the EEC
     type-approval procedure .   It also grants manufacturers the facility of
     requesting that the Community requirements be taken as the basis for
     inspection where national type-approval is granted .
     For the moment there is no national type-approval procedure in some new
     Member States and so it is necessary to provide for provisions enabling
     the use of tractors complying with the requirements of the Directive
     ( Article 8 ) to be guaranteed in these States »
     Article 9 defines an agricultural or forestry tractor and sets out the
     scope of the Directive . This scope is precisely defined in order to
     exclude highly specific tractors which cannot meet the test requirements .
     These include , inter alia, crawler, straddle , vineyard, and certain
     garden or horticultural tractors .
 ---pagebreak---                                           - 5 -
      Tractors of these special types will be included m the scope of the
      D-irective as and when suitable testing requirements have been drawn up.
      Article 10 obliges all tractors referred to in this Directive to be
      fitted with a roll-over protection structure fulfilling the requirements
      of the Directive .  However , up to a date still to be determined devices
      meeting the requirements of Directive 75/536/EEC on dynamic testing
      shall also be accepted .
      Article 11 states that the requirements of the annexes may be amended
      in order to adapt them to technical progress via the procedure set out
      in Article 13 of Council Directive 74/15Q/EEC      4 March 1974 on
      type-approval •
      Article 12 provides for a period of eighteen months during wich the
      Member States can adapt to the Directive .
      Finally , the Commission must be informed within a reasonable time of
      any draft provisions drawn up by the Member States in the field covered
      by the Directive so that it can make comments if necessary ( Article 6 ,
      sub-section 2 ).
III . Consultation of the European Parliament and the Economic and Social Committee
      The opinion of these two bodies is required pursuant to the provisions of
      Article 100, paragraph 2 ,

Having regard to the proposal from the Commission ,

Having regard to the opinion of the Economic and Social Committee ,
Whereas the technical requirements ' "with which tractors must comply
pursuant to national laws relate inter alia1 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 Council Directive 74/l50/EEC of 4 March 1974 °n "the

construction and testing requirements and to inform the other Member
States of its findings by sending them a copy of the component type-approval
certificate completed for each type of roll-over protection structure

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 ;

of the roll-over protection structure , in particular those concerning the
dimensions , doors , safety glass , devices to prevent continuous rolling
if the tractor overturns , and protection of passengers , will he 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 co­
vered by this Directive to be fitted with roll-over protection structures ;
whereas until a date to be determined the tractors referred to in Council
Directive 77/536/nEC 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 fo.estry tractors ( l ) should also be able
to be fitted , at the manrifaoturers discretion , with a roll-over protective
structure complying with this. Directive       ;

reciprocal recognition by Member States of the checks carried out by each
of them on the basis of the common requirements ,

CONDITIONS  FOR EEC COMPONENT TYPE-APPROVAL
DEFINITIONS
A roll-over protection structure ( safety cab  or frame ), here­
after called protection structure , 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 .
The structures menti oned in 1.1 are characterized by the fact
that , in the event of roll-over , they ensure an unobstructed
space inside them large enough to protect the driver .
GENERAL REQUIREMENTS
Every protection structure and its attachment to a tractor mus
be so designed and constructed as to fulfil the essential
purpose laid down in 1 .
This requirement shall be checked by the        test method
described in Annex III .
APPLICATION FCR EEC COMPONENT TYPE-APPROVAL
The application for EEC component type-approval with regard to
the strength of a protection structure and the strength of its
attachment to a tractor shall be submitted by the tractor rranu
facturer or by the manufacturer of the protection structure or

      CONDITIONS FOR TESTING THE STRENGTH OP THE PROTECTION STRUCTURES AND
                         OP THEIR ATTACHMENT TO TRACTORS
1.                GENERAL REQUIREMENTS
1.1 .             Test purposes
                  Tests made using special rigs are intended to simulate such
                   leads as are imposed on the protection structure , when the
                  tractor overturns . These tests , described in Annex III enable
                  observations to be made on the strength of the protection
                  structure and any brackets attaching it to the tractor and any
                  parts of the tractor which transmit the test force .
1.2 .             Preparation for tests
1.2.1 .           The protection structure shall be in accordance with the series
                  production specification . It shall be attached in accordance with
                  the manufacturers' declared method of attachment to one of the
                  tractors for which it is designed . A complete tractor is not
                   required for the test ; however , the protection structure and parts
                  of the tractor for the tests on which it is attached shall repre­
                  sent for structural purposes an operating installation , subsequently
                  described as the assembly , to ensure the integrity of the entire
                  system .
1.2.2 .           The assembly shall be secured to the bedplate so that the             i
                  members connecting the assembly and the bedplate do not deflect
                  significantly in relation to the protection structure under
                  loading . The assembly shall not receive any support under
                  leading other than that due to the initial attachment .
1.2.3 .           The assembly must be supported and secured or modified so that
                  all the test energy is absorbed by the protection structure and
                  its attachment to the rigid components of the tractor .
1.2.3.1 .         To comply with the requirements of              1.2 . 3 ., the modi­
                  fication shall lock any vehicle ride suspension system so as
                  to ensure that it does not absorb any of the test energy .
1.2.4 .           For the tests the tractor shall be fitted with all structural
                  components of the series production which may influence the
                  strength of the 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 in accordance
                  with the requirements of          4.1 .

                      ANNEX III
                  TEST PROCEDURE
HORIZONTAL LOADING AND CRUSHING TESTS
General previsions for horizontal loading tests
The leads applied to the protection structure shall be dis­
tributed by means of a stiff beam 150 mm wide and not more than
700 mm long located normal to the direction of load application .
The rate of deflection under loading shall , not be greater than
5 mm / s . As the load is applied F and D shall be recorded
simultaneously at deflection increments of 15 mm or less , tc
ensure accuracy . Once the initial application has commenced , the
load shall not be reduced until the test has been completed ;
but it is permitted tc cease increasing the lead if desired ,
e.g. to record measurements .
If the structural member tc which the lead is to be applied is
curved , a beam or plate for applying the load may be provided .
It shall , however , comply with the requirements of 1.1 .
so far as load application is concerned , and the requirements
of              2.1.2 . of Annex II . It may be equipped with a
means for preventing it being displaced sideways due to the
curvature of the structure .
If no structural cross member exists at the point of application ,
a substitute test beam which does not add strength to the
structure may be utilized to complete the test procedure .
The structure shall be inspected when the lead is removed after
each loading test has been completed . If cracks or tears have-
occurred during loading , the overload test specified in 1.4 .
shall be carried out before proceeding to the next leading in
the sequence given in 3.1.1.1 . of Annex II .
Longitudinal loading ( see fig . 3 of Annex IV )
Load application shall be horizontal parallel to the vertical
median plane of the tractor .
It shall be applied on the same side of the tractor as the
side lead .
It shall be applied tc the uppermost transverse structurel member
of the protection structure ( i.e. that part which would be likely
to strike the ground in an overturning incident ).
 ---pagebreak---  Annex III , p. 2                         - 12 -
            The point of application of the Load shall be located 1 / 6th of the
            width of the top of the protection structure inwards from the
            outside corner . The width of the protection structure shall be
            taken as the distance between two lines parallel tc the vertical
            median plane of the tractor touching the outside extremities of
            the protection structure in the horizontal plane touching the top
            of the uppermost transverse structural rrembers .
            The length of the beam shall be not less than 1 / 3 of the width of
            the protection structure ( as previously described ) and not rrore
            than 49 mm more than this minimum .
            The longitudinal leading is applied from the rear or front as
            defined in 3.1.1.1 . of Annex II .
            Stop the test when :
            a ) the strain enercy absorbed by the protection structure is equal to or
                greater than the required enercy input        where       = 1.4 M.
            b ) the structure infringes     the zone of clearance or leaves the
                zone of clearance unprotected .
1.3 .       Loading from the side ( see Figure 1 of Annex IV )
            The leading shall be applied horizontally at 90° to the vertical
            median plane of the tractor . It shall te applied to the upper
            extremity of the protection structure at a point 300 mm forward of the
            seat reference point . If the protection structure has any projection
            on the side which would be certain to contact the ground first during \
            a sideways overturn the leading shall be applied at that point .
            The length of the beam shall be not more than 700 mm but however
            it shall be as leng as practicable .
            Stop the test when :
            a ) the strain energy absorbed by the protection structure is equal tc
                or greater than the required enercy input E ^ g / where E ^ s = 1.75 M.
       or   b ) the structure infringes     the zone of clearance or leaves the
                zone of clearance unprotected .
1.4 .       Overload test
            An overload test shall be carried out following a tear occurring during
            a horizontal     leading test carried out in accordance with 1.2 . and
            1.3 . but not 1.7 .
            This requirement does not arise in respect of tears not detrimental to
            the structural integrity of the protection structure , e.g. in a
            cladding panel . An increase in length of an existing tear , as well as
            a new tear commencing shall constitute a tear occurring .
            The energy overload test shall in each case be related to the main
            horizontal test it follows .

      Stop the test when the enerçy
                    E' .  =  1.20 E.
                       i            i
      E.. is      when the overload follows a longitudinal loading and
      E.lisis E. when the overload follows a side loadinga ,
      E.. 1 is measured as the sum of the area contained within the
      force / deflection diagram of the original loading up to the
      point where the load is removed ( Ea ), and the total area under
      the force/ deflection diagram of the overload test ( E ".)
      ( See Figure 4 c of Annex IV ).
      At the point which E' . is aborbed the force F 1 shall be not less
      than 0.8 F max', where    F max is the maximum force occurringJ in
      the force / deflection diagram .
      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 .
1.5 . Crushing at the rear
      The beam shall be positioned across the rear uppermost structural
      members and the resultant of crushing forces shall be located
      in the vertical longitudinal reference plane . A force F = 20 M
      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 and the full force applied .
      The force F « shall be applied for a minimum of five seconds
      following tne' cessation of visually detectable deflection .
      Stop the test if the structure infringes the zone of clearance or
       leaves the ? one of clearance unprotected .
1.6 . Crushing at the front
      The beam shall be positioned across the front uppermost structural
      members and the resultant of crushing forces shall be located in
      the vertical longitudinal reference plane . A force F^ = 20 M
      shall be applied .
 ---pagebreak---  Annex III , p. 4                         - 14-
                 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 and the full
                 force applied .
                  The force Ff shall be applied for a minimum of five seconds
                  following the cessation of the visually detectable deflection .
                  Stop the test if the structure infringes the zone of clearance or
                   leaves the zone of clearance unprotected .
1.7 .             Second longitudinal loading
                 Load application shall be horizontal parallel tc the vertical
                 median plane of the tractor .
                 It shall be applied in the opposite direction to and at the
                 corner furthest from the longitudinal leading in 1.2 .
                 It shall be applied to the uppermost transverse structural
                 member of the protection structure ( i.e. that part which would
                 be likely to strike the ground in an overturning incident ).
                 The point of application of the load shall be located 1 / 6th of
                 the width of the top of the protection structure inwards from
                 the outside corner . The width of the protection structure shall
                 be taken as the distance between two lines parallel to the          *
                 vertical median plane of the tractor touching the outside
                 extremities of the protection structure in the horizontal plane
                touching the top of the uppermost transverse structural members .
                 The length of the beam shall be not less than 1 / 3 of the width
                of the protection structure ( as previously described ) and not
                more than 49 mm more than this minimum .
                 If the structural member to which the lead is to be applied is
                 curved , a beam or plate for applying the load may be provided .
                 It shall , however , comply with the requirements of 1.1 .
                 so far as load application is concerned , and the requirements
                of             2.1.2 . of Annex II . It may be equipped with a means
                for preventing it being displaced sideways due to the curvature
                of the structure .
                The second longitudinal loading is applied from the rear or front
                as defined in 3.1.1.1 . of Annex II . If from the front , it shall
                be applied on the same side of the centreline as that on which

the side Load is applied . If no structural cress member exists
at the point of application , a substitute test beam which does
not add strength to the structure may be utilized to complete
this test procedure .
Stop the test when :
a ) the strain energy absorbed by the structure is equal tc or
    greater than the required energy input E. ., where
    EU2 = 0,35 M.                            1L
b ) the structure infringes on the zone of clearance or leaves
    the zone of clearance unprotected .
Zone of clearance
The zone of clearance is illustrated in             Figure 6 of
Annex IV   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
leading but tc remain perpendicular to the floor of the tractor
or of the             protection structure if this is resiliently
mounted .
Where the steering wheel is adjustable , its position shoulc be
that for normal seated driving .
The boundaries of the zone shall be taken as :
Vertical planes 250 mm on either side of the reference plane
extending upwards from the seat reference point for 300 mm .
Parallel planes extending from the upper edge of plane 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 loading is applied is at least
100 mm from the reference plane .
A horizontal plane 900 mm above the seat reference point .
An inclined plane perpendicular to the reference plane and
including a point 900 mm directly above the seat reference point
and the rearrrost point of the seat backrest .

 2.2.5 .         A          . plane perpendicular to the reference plane extending
                 downwards from the rearmost point of the seat in contact with the
                 seat backrest throughout its length .
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 tc the reference plane ,
                 having a radius of 900 mm 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 tc 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 the surface 2.2.7 .
2.2.9 .          A vertical plane , perpendicular to the reference plane , 40 mm
                 forward of the steering wheel .

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 adjust­
                 ment range where this is independent of adjustment of its        '
                 horizontal position . The reference point shall be established
                 using the apparatus illustrated in Annex IV , Figures 7 and 8
                 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 ischuin humps ( A ) and loin ( B ), the joint ( B ) being

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 above-mentioned 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
                 mid point of its dynamic range . The apparatus shall be
                 positioned on the seat . It shall then be loaded with a force

          of the backrest board shall be lightly pressed tangentially
          against the backrest .
          If it is not possible to determine definite tangents to each area of
          the backrest ( below and above 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 which is 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.        Controls and measurements to be made
3.1 .     Fractures and cracks
          All structural members , joints , attaching brackets and parts of the
          tractor which transmit the loading force shall fce free from fractures
          or cracks detectable by visual inspection , except in the two
          following cases :
          - the last crushing test ( Test 4 in 3.1.1.1 . of Annex II )
          - the overload test carried out as in 1.4 .
          Spot or tack welding used for the attachment of cladding panels
          shall not be considered as affecting the integrity of the protection
          structure and failures of them shall not constitute either a
          requirement for an overload test or non-compliance in respect cf
          freedom from fracture and cracks .
          Tears not detrimental to the structural integrity of the protection
          structure are permitted .
3.2 .     Zone of clearance
          During each test the 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 2.1 . .
          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 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 loading was
          applied .

                 After 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 .

                 protection structure and the strength of its attachment to the tractor shall be submitted by the
                 tractor manufacturer or by his authorized 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 EEC component type-ap-
                 proval was granted .
           4.    The holder of the EEC type-approval may ask for its extension for other types of protection
                 structures.
           5.    The competent authoriues shall grant such extension on the following conditions :
           5.1 . the new type of              protection structure and its tractor attachment have received EEC
                 component type-approval ;
           5.2.  it is designed to be mounted on the type of tractor for which the extension of the EEC type-
                 approval is requested;
           5.3 . the attachment of the protection structure to the tractor corresponds to that which was tested
                 when EEC component type-approval was granted.
           6.    A certificate, of which a model is shown in Annex IX , shall be annexed to the EEC type-ap-
                 proval certificate for each type-approval or type-approval extension which has been granted or
                 refused .
           7.    If the application for EEC type- approval for a type of tractor is introduced at the same time as
                 the request for EEC component type-approval for a type of                 protection structure in­
                 tended to be mounted on the type of tractor for which EEC type-approval is requested, the
                 checks laid down in 2 and 3 will not be made.
