COUNCIL DIRECTIVE
of 26May 1986
on rear-mounted roll-over protection structures of narrow-track
wheeled agricultural and forestry tractors
(86/298/EEC)
THE COUNCIL OF THE EUROPEAN COMMUNITIES,
Having regard to the Treaty establishing the European Economic
Community, and in particular Article 100 thereof,
Having regard to the proposal from the Commission(1),
Having regard to the opinion of the European Parliament(2),
Having regard to the opinion of the Economic and Social
Committee(3),
Whereas Council Directive 74/150/EEC of 4 March 1974 on the
approximation of the laws of the Member States relating to the type-approval of wheeled agricultural or forestry tractors(
4), as last amended
by the Act of Accession of Spain and Portugal, lays down that the
necessary provisions for the implementation of the EEC type-approvalprocedure in respect of individual tractor parts or characteristics shouldbe specified in special directives; whereas the provisions relating toroll-over protection structures and their attachments to tractors were
laid down by Directives 77/536/EEC(
5) and 79/622/EEC(6), as last
amended by the Act of Accession of Spain and Portugal; whereas thesetwo Directives cover respectively dynamic and static testing procedures— either of which may be employed by manufacturers for the present— and relate to standard tractors, that is, tractors having a maximumground clearance of 1 000 mm and a fixed or adjustable track width
of one of the driving axles of not less than 1 150 mm and weighing
between 1,5 and 4,5 tonnes in the case of tractors covered by the‘dynamictesting’ Direc tive and not less than 800 kilograms in thecase of tractors covered by the ‘static testing’ Directive;
Whereas the tractors covered by this Directive have a maximum
ground clearance of 600 mm, a minimum track width of both axles ofless than 1 150 mm and a mass greater than 600 kilograms; whereasthe roll-over protection structures of these tractors, which are used for
specific activities, can be made subject to specific requirement or
requirements other than those of Directive 77/536/EEC and 79/622/EEC;
Whereas the technical requirements with which such ‘narrow-track’
tractors must comply pursuant to national laws relate inter alia to roll-
over protection structures and to their attachment to the tractor;whereas those requirements differ from one Member State to another;whereas it is therefore necessary that all Member States adopt the same
requirements either in addition to or in place of their existing rules in
order, in particular, to allow the EEC type-approval procedure whichwas the subject of Directive 74/150/EEC to be introduced in respectof each type of tractor;
Whereas this Directive covers roll-over protection structures of the
rear-mounted rollbar, frame or cab type having a zone of clearancewhose upper limit is 900 mm above the seat reference point in orderto provide a sufficiently large area or unobstructed space for the
protection of the driver; whereas another special Directive will be
adopted in respect of roll-over protection structures having two pillarsmounted in front of the driver;1986L0298 — EN — 04.01.1990 — 001.001 — 2

Whereas a harmonized component type-approval procedure for roll-
over protection structures and their attachment to the tractor makes itpossible for each Member State to check compliance with the common
construction and testing requirements and to inform the other Member
States of its findings by sending them copies of the component type-approval certificate completed for each type of roll-over protectionstructure and its attachment to the tractor; whereas the placing of anEEC 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; whereascommon requirements concerning other elements and characteristics ofthe roll-over protection structure, in particular, devices to preventcontinuous roll-over if the tractor overturns, and protection of occu-pants, will be laid down at a later date;
Whereas the harmonized requirements are intended principally to
ensure safety on the road and at work throughout the Community;
whereas, for this reason, it is necessary to introduce the obligation fortractors covered by this Directive to be fitted with roll-over protectionstructures;
Whereas the approximation of the national laws relating to these trac-
tors entails reciprocal recognition by Member States of the checkscarried out by each of them on the basis of the common requirements,
HAS ADOPTED THIS DIRECTIVE:
Article 1
This Directive shall apply to tractors as defined in Article 1 of Direc-
tive 74/150/EEC having the following characteristics:
— ground clearance of not more than 600 mm measured beneath the
lowest points of the front or rear axles, allowing for the differential,
— fixed or adjustable minimum track width of less than 1 150 mm for
the axles fitted with the widest tyres; since the axle fitted with thewidest tyres is assumed to be adjusted to a maximum track width of1 150 mm, the other axle must be capable of being adjusted in sucha way that the outer edges of the narrowest tyres do not projectbeyond the outer edges of the tyres on the axle with the widest
tyres. Where both axles are equipped with wheels and tyres of the
same size, the fixed or adjustable track width of both axles must beless than 1 150 mm,
— mass greater than 600 kilograms and corresponding to the unladen
weight of the tractor as defined in section 2.4 of Annex I to Direc-tive 74/150/EEC, including the roll-over protection structure fittedin compliance with this Directive and tyres of the largest sizerecommended by the manufacturer.
Article 2
1. Each Member State shall grant EEC component type-approval for
any type of roll-over protection structure and its tractor attachment
which satisfies the construction and testing requirements laid down in
Annexes I to IV.
2. A Member State which has granted EEC component type-
approval shall take the measures required to verify, in so far as isnecessary and if need be in cooperation with the competent authoritiesin the other Member States, that production models conform to theapproved type. Such verification shall be limited to spot checks.
Article 3
Member States shall, for each type of roll-over protection structure and
its tractor attachment which they approve pursuant to Article 2, issue tothe manufacturer of the tractor or of the roll-over protection structure,1986L0298 — EN — 04.01.1990 — 001.001 — 3

Article 4
1. No Member State may prohibit the placing on the market of roll-
over protection structures or their attachment to the tractors for whichthey are intended on grounds relating to their construction if they bearthe EEC component type-approval mark.
2. Nevertheless, a Member State may prohibit the placing on the
market of roll-over protection structures bearing the EEC componenttype-approval mark which consistently fail to conform to the approvedtype.
That State shall forthwith inform the other Member States and the
Commission of the measures taken, specifying the reasons for its deci-sion.
Article 5
The competent authorities of each Member State shall, within one
month, send to the competent authorities of the ►

Article 6
1. If the Member State which has granted EEC component type-
approval finds that a number of roll-over protection structures and theirtractor attachments bearing the same EEC component type-approvalmark do not conform to the type which it has approved, it shall takethe 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, ifnecessary, where there is serious and repeated failure to conform,extend to withdrawal of EEC component type-approval. The saidauthorities shall take the same measures if they are informed by thecompetent authorities of another Member State of such failure to
conform.
2. The competent authorities of the Member States shall within one
month inform each other of any withdrawal of EEC component type-approval and of the reasons for any such measure.
Article 7
Any decision taken pursuant to the provisions adopted in implementa-
tion of this Directive to refuse or withdraw component type-approvalfor roll-over protection structures and their tractor attachments, or toprohibit their placing on the market or their use, shall set out in detail
the reasons on which it is based. Such decisions shall be notified to the
party concerned, who shall at the same time be informed of the reme-dies available to him under the laws in force in the Member States andof the time limits allowed for the exercise of such remedies.
Article 8
No Member State may refuse to grant EEC type-approval or national
type-approval in respect of a tractor on grounds relating to roll-overprotection structures or their tractor attachment if these bear the EECcomponent type-approval mark and if the requirements laid down inAnnex VIII have been satisfied.1986L0298 — EN — 04.01.1990 — 001.001 — 4

ANNEX I
CONDITIONS FOR EEC COMPONENT TYPE-APPROVAL
1. DEFINITION
1.1. ‘Roll-over protection structure for the driver’, hereinafter 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.
1.2. The structures mentioned in Item 1.1 are characterized by the fact
that, during the tests prescribed in Annexes II and III, they ensure
sufficient unobstructed space to protect the driver.
2. GENERAL REQUIREMENTS
2.1. Every protection structure and its attachment to a tractor must be so
designed and constructed as to fulfil the essential purpose laid down
in Item 1.1 above.
2.2. This condition is considered to be fulfilled when the requirements of
Annexes II and III are complied with.
3. APPLICATION FOR EEC COMPONENT TYPE-APPROVAL
3.1. 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 manufacturer or by the
manufacturer of the protecion structure or by their authorized repre-
sentatives.
3.2. The application for EEC component type-approval shall be accom-
panied by the undermentioned documents in triplicate and by the
following particulars:
— general arrangement drawing either to a scale marked on the
drawing or giving the main dimensions of the protection struc-
ture. This drawing must, in particular, show details of the
mounting components,

brackets and fixing bolts (see Annex V).
3.3. A tractor representative of the tractor type for which the protection
structure to be approved is intended shall be submitted to the tech-
nical service responsible for conducting the component type-
approval tests. This tractor shall be fitted with the protection struc-
ture.
3.4. The holder of EEC component type-approval may request its exten-
sion to other tractor types. The competent authority which has
granted the original EEC component type-approval shall grant the
extension if the approved protection structure and the type(s) of
tractor for which the extension is requested comply with the
following conditions:
— the mass of the unballasted tractor, as defined in Item 1.4 of
Annex II, does not exceed by more than 5 % the reference
mass used in the tests,
— the wheelbase or the moment of inertia in relation to the rear-
wheel axle is not more than the reference wheelbase or moment
of inertia,

ANNEX II
CONDITIONS FOR TESTING THE STRENGTH OF PROTECTION
STRUCTURES AND THEIR ATTACHMENT TO TRACTORS
1. GENERAL REQUIREMENTS
1.1. Test purposes
Tests made using special rigs are intended to simulate such loads as
are imposed on a 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. Test methods
Tests may be performed in accordance with the dynamic procedure
(see Annexes II A and III A) or the staticproc edure (see Annexes II
B and III B) at the manufacturer's choice.
The two methods are equivalent.
1.3. General rules governing preparation for tests
1.3.1. The protection structure must conform to the series production speci-
fications. It shall be attached in accordance with the manufacturer's
recommended method to one of the tractors for which it is designed.
A complete tractor is not required for the strength test in static
testing; however, the protection structure and parts of the tractor to
which it is attached shall represent an operating installation, herein-
after referred to as ‘the assembly’.
1.3.2. For the strength test the tractor must be fitted with all series produc-
tion components which may affect 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 to see whether
the requirements of Items 3.1 and 3.2 have been fulfilled.
All components of the tractor or the protection structure including
weather protection must be supplied or defined in drawings.
1.3.3. For the strength tests, all detachable windows, doors, panels and
non-structural fittings must be removed so that they may not contri-
bute to the strengthening of the protection structure.
1.3.4. Track width
The track width shall be adjusted such that the protection structure
will, as far as possible, not be supported by the tyres during the
strength tests. If these tests are conducted in accordance with the
staticproc edure, the wheels may be removed.
1.4. Tractor reference mass
The reference mass ‘mt’, used in the formulae (see Annex III A and
III B) to calculate the height of fall of the pendulum block, the
loading energies and the crushing forces, shall be at least that
defined in Item 2.4 of Annex I to Council Directive 74/150/EEC
(i.e. excluding ‘optional’ accessories but including coolant, oils,
fuel, tools and driver) plus the protection structure and less 75 kilo-
grams. Not included are ‘optional’ front or rear weights, tyre ballast,
mounted implements, mounted equipment or any specialized compo-
nent.
2. TESTS
2.1. Sequence of tests
The sequence of tests, without prejudice to the additional dynamic
and statictests (Annex III A and Annex III B), is as follows:
2.1.1. Impact (dynamic tests) or loading (static tests) at the rear of the
structure (see Item 1.1 of Annexes III A and III B)1986L0298 — EN — 04.01.1990 — 001.001 — 9
▼B
2.1.2. Rear crushing (dynamic or static tests) (see Item 1.4 of Annexes III
A and III B)
2.1.3. Impact (dynamic tests) or loading (static tests) at the front of the
structure (see Item 1.2 of Annexes III A and III B)
2.1.4. Impact (dynamic tests) or loading (static tests) to the side of the
structure (see Item 1.3 of Annexes III A and III B)
2.1.5. Crushing at the front of the structure (dynamic or static tests) (see
Item 1.5 of Annexes III A and III B)
2.2. General requirements
2.2.1. If, during the test, any part of the restraining equipment breaks or
moves, the test shall be restarted.
2.2.2. No repairs or adjustments to the tractor or to the protection structure
may be carried out during the tests.
2.2.3. The tractor gear-box shall be in neutral and the brakes off during the
tests.
2.2.4. If the tractor is fitted with a suspension system between the tractor
body and the wheels, it shall be blocked during the tests.
2.2.5. The side chosen for application of the first impact on the rear of the
structure (in the case of dynamic tests) or the first load on the rear of
the structure (in the case of static tests) shall be that which, in the
opinion of the testing authorities will result in the application of the
series of impacts or loads under the most unfavourable conditions
for the structure. The lateral impact or load and the rear impact or
load shall be on different sides of the longitudinal median plane of
the protection structure. The front impact or load shall be on the
same side of the longitudinal median plane of the protection struc-
ture as the lateral impact or load.
2.3. Measurement tolerances
2.3.1. Linear dimensions: ± 3 mm.
Except for: — tyre deflection: ± 1 mm,
— structure deflection during horizontal loading:
± 1 mm,
— each of the two measurements for the height of
fall of the pendulum block: ± 1 mm.
2.3.2. Masses: ± 1 %.
2.3.3. Forces: ± 2 %.
2.3.4. Angles: ± 2º.
3. ACCEPTANCE CONDITIONS
3.1. A protection structure submitted for EEC component type-approval
shall be considered as having satisfied the strength requirements if
it fulfils the following conditions:
3.1.1. After each partial test in the dynamic test procedure, it shall be free
from tears or cracks as described in point 3.1 of Annex III (A).
If, during the dynamic test, significant tears or cracks appear, an
additional impact test or crushing test as defined in point 1.6 of
Annex III (A) must be performed immediately after the test which
caused these tears or cracks to appear.
3.1.2. During statictesting, at the point when the energy required is
attained in each horizontal load test prescribed or in the overload
test (see Figures 10a, 10b and 10cof Annex IV) the forc e must be
greater than 0,8 Fmax.
3.1.3. If, during a static test, cracks or tears appear as a result of the appli-
cation of the crushing force, an additional crushing test, as defined
in Item 1.7 of Annex III B, may be carried out immediately after
the crushing test which caused the cracks or tears to appear.
3.1.4. Additional cracks or tears and/or entry into or lack of protection of
the zone of clearance are permitted during the overload test.1986L0298 — EN — 04.01.1990 — 001.001 — 10
▼M1

as a result of the deflections of the structure.
4. TEST REPORT
4.1. The test report shall be attached to the EEC component type-
approval certificate referred to in Annex VII. The presentation of
the report shall be as shown in Annex V. The report shall include:
4.1.1. A general description of the protection structure's shape and
construction (through drawings 1/20 scale for general drawings and1/25 for attachment details) including materials and fastenings,
external dimensions of the tractor with protection structure fitted,

A.APPARATUS AND EQUIPMENT FOR DYNAMIC TESTS
1. PENDULUM BLOCK
1.1. A pendulum block shall be suspended by two chains or wire ropes
from pivot points not less than 6 meters above the ground. Means
shall be provided for adjusting independently the suspended height
of the block and the angle between the block and the supporting
chains or wire ropes.
1.2. The mass shall be 2 000 ± 20 kilograms excluding the mass of the
chains or wire ropes which themselves shall not exceed 100 kilo-
grams. The length of the sides of the impact face shall be
680 ± 20 mm (see Annex IV, Figure 4). The block shall be filled
in such a way that the position of its centre of gravity is constant
and coincides with the geometrical centre of the parallelepiped.
1.3. The parallelepiped shall be connected to the system which pulls it
backwards by an instantaneous release mechanism which is so
designed and located as to enable the pendulum block to be released
without causing any significant oscillation of the parallelepiped.
2. PENDULUM SUPPORTS
The pendulum pivot points shall be rigidly fixed so that their displa-
cement in any direction does not exceed 1 % of the height of fall.
3. LASHINGS
3.1. The tractor shall be anchored to the ground by means of restraining
and tensioning devices with rails rigidly attached to a non-yielding1986L0298 — EN — 04.01.1990 — 001.001 — 11
▼B
base. The rails shall be an appropriate width apart to enable
thetractor to be lashed in accordance with Annex IV, Figures 5, 6
and 7. During each test, the wheels of the tractor and the axle stands
used shall rest on the non-yielding base.
3.2. The tractor shall be lashed to the rails by means of wire rope with
round strand, fibre core, construction 6 × 19 in accordance with ISO
2408 and a nominal diameter of 13 mm. The metal strands shall
have an ultimate tensile strength of 1 770 MPa.
3.3. The central pivot of an articulated tractor shall be supported and
lashed down as appropriate for all tests. For the lateral impact test,
the pivot shall also be propped from the side opposite the impact.
The front and rear wheels need not be in line if this makes it more
convenient to attach appropriate wire ropes.
4. WHEEL PROP AND BEAM
4.1. A softwood beam 150 mm square shall be used as a prop for the
wheels during the lateral impact tests (see Annex IV, Figures 5, 6
and 7).
4.2. During the lateral impact tests, a softwood beam shall be clamped to
the floor to brace the rim of the wheel opposite the side of impact as
shown in Annex IV, Figure 7.
5. PROPS AND LASHINGS FOR ARTICULATED TRACTORS
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
protection structure is fitted is a rigid as that of a rigid tractor.
5.2. Additional specific details are given in Annex III A for the impact
and crushing tests.
6. TYRE PRESSURE AND DEFLECTION
6.1. The tractor tyres shall not be liquid-ballasted and shall be inflated to
the pressures prescribed by the tractor manufacturer for field work.
6.2. The lashings shall be tensioned in each particular case such that the
tyres undergo a deflection equal to 12 % of the tyre wall height
(distance between the ground and the lowest point of the rim) before
tensioning.
7. CRUSHING RIG
A rig as shown in Annex IV, Figure 8, shall be capable of exerting a
downward force on a 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 the crushing force.
8. MEASURING APPARATUS
8.1. A device such as that illustrated in Annex IV, Figure 9, for
measuring the elastic deflection (the difference between the
maximum momentary deflection and the permanent deflection).
8.2. A device for checking that the protection structure has not entered
the zone of clearance and that the latter has remained within the
structure's protection during the test (see Item 3.2.2 of Annex III A).
B.APPARATUS AND EQUIPMENT FOR STATIC TESTS
1. STATIC TESTING RIG
1.1. This rig shall enable horizontal thrusts or loading to be applied to
the structure.
1.2. Provision must be made so that the load can be uniformly distributed
normal to the direction of loading and along a beam having a length
of one of the exact multiples of 50, between 250 and 700 mm.
The stiff beam shall have a vertical face dimension of 150 mm.
The edges of the beam in contact with the protection structure shall
be curved, with a maximum radius of 50 mm.1986L0298 — EN — 04.01.1990 — 001.001 — 12
▼B
1.3. The pad shall be capable of being adjusted to any angle in relation
to the direction of the force, in order to be able to follow the angular
variations of the structure's load-bearing surface as the structure
deflects.
1.4. Direction of the force (deviation from horizontal and vertical)
— at start of test, under zero load: ± 2º,
— during test, under load: 10º above and 20º below the horizontal.
These variations must be kept to a minimum.
1.5. The deflection rate shall be slow (less than 5 mm/s) so that the load
may at all moments be considered as ‘static’.
2. APPARATUS FOR MEASURING THE ENERGY ABSORBED BY
THE STRUCTURE
2.1. The ‘force versus deflection’ curve shall be plotted in order to deter-
mine the energy absorbed by the structure. There is no need tomeasure the force and deflection at the point where the load is
applied to the structure; however, ‘force’ and ‘deflection’ shall be
measured simultaneously and co-linearly.
2.2. The point of origin of deflection measurements shall be selected
such that only the energy absorbed by the structure and/or the
deflection of certain parts of the tractor is taken into account. Theenergy absorbed by the deflection and/or the slipping of the
anchoring shall be ignored.
3. MEANS OF ANCHORING THE TRACTOR TO THE GROUND
3.1. The tractor shall be anchored to the ground by means of restraining
and tensioning devices with rails rigidly attached to a non-yielding
base. The rails shall be an appropriate width apart to enable the
tractor to be lashed. During each test, the wheels and the axle stands
used shall rest on the base.
3.2. The tractor shall be anchored to the rails by any suitable means
(plates, wedges, wire ropes, jacks, etc.) such that it cannot move
during the tests. This requirement shall be checked while the loads
are being applied, by means of the usual devices for measuring
length. If the tractor moves, the entire test shall be repeated, unless
the system for measuring the deflections used in plotting the ‘force
versus deflection’ curve is connected to the tractor.
4. CRUSHING RIG
A rig as shown in Figure 8 of Annex IV shall be capable of exerting
a downward force on a 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 the crushing force.
5. OTHER MEASURING APPARATUS
5.1. A device such as that illustrated in Figure 9 of Annex IV, for
measuring the elastic deflection (the difference between the
maximum momentary deflection and the permanent deflection).
5.2. A device for checking that the protection structure has not entered
the zone of clearance and that the latter has remained within the
structure's protection during the test (see Item 3.2.2 of Annex III B).

ANNEX III
TEST PROCEDURE
A.Dynamic tests
1. IMPACT AND CRUSHING TESTS1.1. Impact at the rear
1.1.1. The tractor shall be so placed in relation to the pendulum block that
the block will strike the protection structure when the impact face of
the block and the supporting chains or wire ropes are at an angle
with the vertical plane equal to m
t/100 with a 20º maximum, unless,
during deflection, the protection structure at the point of contact
forms a greater angle to the vertical. In this case the impact face of
the block shall be adjusted by means of an additional support so that
it is parallel to the protection structure at the point of impact at the
moment of maximum deflection, the supporting chains or wire ropes
remaining at the angle defined above.
The suspended height of the block shall be adjusted, and necessary
steps taken so as to prevent the block from turning about the point of
contact.
The point of impact shall be that part of the protection structure
likely to hit the ground first in a rearward overturning accident,
normally the upper edge. The position of the centre of gravity of
the block shall be one-sixth of the width of the top of the protection
structure inwards from a vertical plane parallel to the median plane
of the tractor touching the outside extremity of the top of the protec-
tion structure.
If the structure is curved or protruding at this point, wedges enabling
the impact to be applied thereon will have to be added, without
thereby reinforcing the structure.
1.1.2. The tractor shall be lashed to the ground by means of four wire
ropes, one at each end of both axles, arranged as indicated in Figure
5 of Annex IV. The front and rear lashing points shall be located at
a distance such that the wire ropes make an angle of less than 30º
with the ground. The rear lashings shall in addition be so arranged
that the point of convergence of the two wire ropes is located in
the vertical plane in which the centre of gravity of the block travels.
The wire ropes must be tensioned such that the tyres undergo the
deflections given in Item 6.2 of Annex II A.
With the wire ropes tensioned, the wedging beam shall be placed in
front of and tight against the rear wheels and then fixed to the
ground.
1.1.3. If the tractor is of the articulated type, the point of articulation shall,
in addition, be supported by a wooden block at least 100 mm square
and firmly lashed to the ground.
1.1.4. The pendulum block shall be pulled back so that the height of its
centre of gravity above that at the point of impact is given by one
of the following two formulae:
H¼2;165/C210/C08mtL2or H¼5;73/C210/C02I:
The block must then be released so as to strike the protection struc-
ture.
1.2. Impact at the front
1.2.1. The tractor shall be so placed in relation to the pendulum block that
the block will strike the protection structure when the impact face of
the block and the supporting chains or wire ropes are at an anglewith the vertical plane, equal to m
t/100 with a 20º maximum, unless,
during deflection, the protection structure at the point of contact
forms a greater angle to the vertical. In this case the impact face of
the block shall be adjusted by means of an additional support so that
it is parallel to the protection structure at the point of impact at the
moment of maximum deflection, the supporting chains or wire ropes
remaining at the angle defined above.1986L0298 — EN — 04.01.1990 — 001.001 — 15
▼B
The suspended height of the pendulum block shall be adjusted and
necessary steps taken so as to prevent the block from turning about
the point of contact.
The point of impact shall be that part of the protection structure
likely to hit the ground first if the tractor overturns sideways while
travelling forward, normally the upper edge. The position of
thecentre of gravity of the block shall be one-sixth of the width of
the top of the protection structure inwards from a vertical plane
parallel to the median plane of the tractor touching the outside extre-
mity of the top of the protection structure.
If the structure is curved or protruding at this point, wedges enabling
the impact to be applied thereon will have to be added, without
thereby reinforcing the structure.
1.2.2. The tractor shall be lashed to the ground by means of four wire
ropes, one at each end of both axles, arranged as indicated in Figure
6 of Annex IV. The front and rear lashing points shall be located at
a distance such that the wire ropes make an angle of less than 30º
with the ground. The rear lashings shall, in addition, be so arranged
that the point of convergence of the two wire ropes is located in the
vertical plane in which the centre of gravity of the pendulum block
travels.
The wire ropes must be tensioned such that the tyres undergo the
deflections given in Item 6.2 of Annex II A.
With the wire ropes tensioned, the wedging beam shall be placed
firmly behind the rear wheels and then fixed to the ground.
1.2.3. If the tractor is of the articulated type, the point of articulation shall
in addition be supported by a wooden block at least 100 mm square
and firmly lashed to the ground.
1.2.4. The pendulum block shall be pulled back so that the height of its
centre of gravity above that at the point of impact is given by one
of the following two formulae, to be chosen according to the refer-
ence mass of the tractors subjected to the tests:
H = 25 + 0,07 mtfor tractors with a reference mass of less than
2 000 kilograms,
H = 125 + 0,02 mtfor tractors with a reference mass of more than
2 000 kilograms.
The pendulum block must then be released so as to strike the protec-
tion structure.
1.3. Impact from the side
1.3.1. The tractor shall be so placed in relation to the pendulum block that
the block will strike the protection structure when the impact face of
the weight and the supporting chains or wire ropes are vertical
unless, during deflection, the protection structure at the point of
contact forms an angle to the vertical. In this case the impact face
of the block shall be adjusted by means of an additional support so
that it is parallel to the protection structure at the point of impact at
the moment of maximum deflection, the supporting chains or wire
ropes remaining vertical on impact.
The suspended height of the block shall be adjusted and necessary
steps taken so as to prevent the block from turning about the point
of contact.
The point of impact shall be that part of the protection structure
likely to hit the ground first in a sideways overturning accident,
normally the upper edge. Unless it is certain that another part of
this edge would hit the ground first, the point of impact shall be in
the plane at right angles to the median plane and passing 200 mm in
front of the seat reference point, the seat being set at the mid posi-
tion of the longitudinal seat adjustment.
1.3.2. The tractor wheels on the side which is to receive the impact shall
be lashed to the ground by means of wire ropes passing over the
corresponding ends of the front and rear axles. The wire ropes shall
be tensioned to produce the tyre deflection values given in Item 6.2
of Annex II A on the side which is to receive the impact.
With the wire ropes tensioned, the wedging beam shall be placed on
the ground, pushed tight against the tyres on the side opposite that
which is to receive the impact and then fixed to the ground. It may1986L0298 — EN — 04.01.1990 — 001.001 — 16
▼B
be necessary to use two beams or wedges if the outer sides of the
front and rear tyres are not in the same vertical plane.
The prop shall then be placed as indicated in Figure 7 of Annex IV
against the rim of the wheel opposite to the impact, pushed firmly
against the rim and then fixed at its base.
The length of the rop shall be chosen such that it makes an angle of
30 ± 3º with the ground when in position against the rim. In addi-
tion, its length must, if possible, be between 20 and 25 times
greater than its thickness and its width between two and three times
greater than its thickness. The props shall be shaped at both ends as
shown in the details of Figure 7 of Annex IV.
1.3.3. If the tractor is of the articulated type, the point of articulation shall,
in addition, be supported by a wooden block at least 100 mm square
and laterally supported by a device similar to that provided for in
Item 1.3.2 against the rear wheel. The point of articulation shall
then be lashed firmly to the ground.
1.3.4. The pendulum block shall be pulled back so that the height of its
centre of gravity above that at the point of impact is given by one
of the following two formulae, to be chosen according to the refer-
ence mass of the tractors subjected to the tests:
H = 25 + 0,20 mtfor tractors with a reference mass of less than
2 000 kilograms,
H = 125 + 0,15 mtfor tractors with a reference mass of more than
2 000 kilograms.
The pendulum block must then be released so as to strike the protec-
tion structure.
1.4. Crushing at the rear
The beam shall be positioned over the rear uppermost structural
member(s) and the resultant of the crushing forces shall be located
in the tractor's median plane.
A force, Fv=2 0mtshall be applied.
Where the rear part of the protection structure roof will not sustain
the full crushing force, the force shall be applied until the roof is
deflected to coincide with the plane joining the upper part of the
protection structure with that part of the rear of the tractor capable
of supporting the vehicle's mass when overturned.
The force shall then be removed, and the tractor or loading force
repositioned so that the beam is over that point of the protection
structure which would then support the tractor when completely
overturned.
The force Fvshall then be applied.
It shall be applied for a minimum of five seconds following the
cessation of any visually detectable deflection.
1.5. Crushing at the front
The beam shall be positioned over the front uppermost structural
member(s) and the resultant of the crushing forces shall be located
in the tractor's median plane.
A force, Fv=2 0mtshall be applied.
Where the front part of the protection structure roof will not sustain
the full crushing force, the force shall be applied until the roof is
deflected to coincide with the plane joining the upper part of the
protection structure with that part of the front of the tractor capable
of supporting the vehicle's mass when overturned.
The force shall then be removed, and the tractor or loading force
repositioned so that the beam is over that point of the protection
structure which would then support the tractor when completely
overturned.
The force Fvshall then be applied.
It shall be applied for a minimum of five seconds following the
cessation of any visually detectable deflection.1986L0298 — EN — 04.01.1990 — 001.001 — 17
▼M1
1.6. Additional tests
1.6.1. If cracks or tears which cannot be considered negligible appear
during an impact test, a second, similar test, but with a height of
fall of:
H0¼H
10/C212þ4a
1þ2a
shall be performed immediately after the impact test causing these
tears or cracks to appear, ‘a’ being the ratio of the permanent defor-
mation to the elasticdeformation (a = Dp/De) as measured at the
point of impact.
The additional permanent deformation due to the second impact
must not exceed 30 % of the permanent deformation due to the first
impact.
In order to be able to carry out the additional test, it is necessary to
measure the elasticdeformation during all of the impac t tests.
1.6.2. If, during a crushing test, significant tears or cracks appear, a
second, similar crushing test, but with a force equal to 1,2 Fv, shall
be performed immediately after the crushing test which caused these
tears and cracks to appear.
2. ZONE OF CLEARANCE
2.1. The zone of clearance is shown in Figures 1, 2a, 2b, 2c, 2d and 2e
of Annex IV.
The zone is defined on the basis of a ‘vertical reference plane’,
generally longitudinal to the tractor and passing through the seat
reference point and the centre of the steering wheel. This plane
must be able to move horizontally with the seat and the steering
wheel during the impact but to remain perpendicular to the floor of
the tractor or of the protection structure if this is resiliently mounted.
2.2. The zone is bounded by the following planes, the tractor being on a
horizontal surface and, where the steering wheel is adjustable, its
position adjusted for normal seated driving.

reference plane, has a radius of 120 mm and is tangential to the
planes defined above in Items 2.2.1 and 2.2.2.
2.2.4. A cylindrical surface — B1C1C2B2— perpendicular to the reference
plane, having a radius of 900 mm and extending forward by 400 mm

following a horizontal line 150 mm forward of the seat reference
point.
2.2.5. A inclined plane — C1D1D2C2— perpendicular to the reference
plane, extending the surface defined in Item 2.2.4 above and passing
through a point 40 mm from the outer edge of the steering wheel.
2.2.6. A vertical plan — D1K1E1E2K2D2— perpendicular to the reference
plane and passing 40 mm in front of the other edge of the steering
wheel.
2.2.7. A horizontal plane — E1F1P1N1N2P2F2E2— passing through the seat
reference point.
2.2.8. A curvilinear surface — G1L1M1N1N1M2L2G2— perpendicular to the
reference plaen and in contact with the back of the seat backrest.
2.2.9. Two vertical planes — K1I1F1E1and K2I2F2E2— parallel to the refer-
ence plane, 250 mm either side of this plane, and bounded towards

defined in Item 2.2.9 above and joining the horizontal plane defined
in Item 2.2.1 above at least 100 mm from the reference plane on the
side where the impact is applied.
2.2.11. Two vertical planes — Q1P1N1M1and Q2P2N2M2— parallel to the
reference plane, 200 mm either side of this plane, and bounded
towards the top 300 mm above the horizontal plane passing through
the seat reference point.
2.2.12. Two portions — I1Q1P1F1and I2Q2P2F2— of a vertical plane, perpen-
dicular to the reference plane and passing 350 mm in front of the
seat reference point.
2.2.13. Two portions — I1Q1M1L1— and I2Q2M2L2— of the horizontal
plane passing 300 mm above the seat reference point.
2.3. Seat location and seat reference point
2.3.1 Seat reference point
2.3.1.1. The refernce point shall be established using the apparatus illustrated
in Figures 3 and 3b of Annex IV. The apparatus shall consist of a
seat pan board and backrest boards. The lower backrest board shall
be jointed in the region of the ischium humps (A) and loin (B), the
joint (B) being adjustable in height.
2.3.1.2. The reference point is defined as the point in the median longitu-
dinal plane of the seat where the tangential plane of the lower
backrest and a horizontal plane intersect. This horizontal plane cuts
the lower surface of the seat pan board 150 mm in front of the
abovementioned tangent.
2.3.1.3. The apparatus shall be positioned on the seat. It shall then be loaded
with a force of 550 N at a point 50 mm in front of joint (A), and the
two parts of the backrest board shall be lightly pressed tangentially
against the backrest.
2.3.1.4. If it is not possible to determine definite tangents to each area of the
backrest (above and below the lumbar region) the following must be
done:
2.3.1.4.1. Where no definite tangent to the lower area is possible the lower
part of the backrest board is pressed against the backrest vertically.
2.3.1.4.2. Where no definite tangent to the upper area is possible the joint (B)
is fixed at a height of 230 mm above the lower surface of the seat
pan board, the backrest board being perpendicular to the latter. Then
the two parts of the backrest board are lightly pressed against the
backrest.
2.3.2. Seat position and adjustment for determining the location of the seat
reference point
2.3.2.1. Where the seat position is adjustable, the seat must be adjusted to its
rear uppermost position.
2.3.2.2. Where the inclination of the backrest and seat pan is adjustable,
these must be adjusted so that the reference point is in its rear upper-
most position.
2.3.2.3. Where the seat is equipped with suspension, the latter must be
blocked at mid-travel, unless this is contrary to the instructions
clearly laid down by the seat manufacturer.
3. MEASUREMENTS TO BE MADE
3.1. Fractures and cracks
After each test all structural members, joints and fastening systems
shall be visually examined for fractures or cracks, any small cracks
in unimportant parts being ignored.
Any tears caused by the edges of the pendulum weight shall be
ignored.
3.2. Zone of clearance
3.2.1. During each test an examination shall be made to see whether any
part of the protection structure has entered the zone of clearance
round the driver's seat as defined in Item 2 of this Annex.1986L0298 — EN — 04.01.1990 — 001.001 — 19
▼B
3.2.2. In addition, an examination shall be made to determine whether any
part of the zone of clearance is outside the protection of the protec-
tion structure. For this purpose it shall be considered to be outside
the protection of the roll-over protection structure if any part of it
would have come into contact with flat ground if the tractor had
overturned towards the direction from which the impact came. For
this purpose the front and rear tyre and track setting shall be
assumed to be the smallest specified by the manufacturer.
3.3. Elastic deflection (on side impact)
The elasticdeflec tion shall be measured 900 mm above the seat
reference point, in the vertical plane passing through the point of
impact. For this measurement, apparatus as shown in Figure 9 of
Annex IV shall be used.
3.4. Permanent deflection
After the final crushing test, the permanent deflection of the protec-
tion 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.

more than 3 % during the last 5 % of the deflection reached when
the energy required is absorbed by the structure (see Figure 10b of
Annex IV).
1.6.2. The overload test involves the gradual increase of the horizontal load
by increments of 5 % of the initial energy requirement up to a
maximum of 20 % of energy added (see Figure 10cof Annex IV).
1.6.2.1. The overload test is satisfactory if, after each increase by 5 %, 10 %
or 15 % in the energy required, the force decreases by less than 3 %
for a 5 % increment and remains more than 0,8 Fmax.
1.6.2.2. The overload test is satisfactory if, after the structure has absorbed
20 % of the added energy, the force exceeds 0,8 Fmax.
1.6.2.3. Additional cracks or tears and/or entry into or lack of protection of

have come into contact with flat ground if the tractor had overturned
towards the direction from which the impact came. For this purpose
the front and rear tyres and track setting shall be assumed to be the
smallest specified by the manufacturer.

The elasticdeflec tion shall be measured 900 mm above the refer-
ence point, in the vertical plane in which the load is applied. For
this measurement, any apparatus similar to that illustrated in Figure
9 of Annex IV, may be used.

ANNEX VIII
CONDITIONS FOR EEC TYPE-APPROVAL
1. The application for EEC type-approval of a tractor with regard to the
strength of a 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 whether the
attachment of the component type-approval was granted.
4. The holder of the EEC type-approval may ask for its extension to
other types of protection structures.
5. The competent authorities shall grant such extension on the
following conditions:
5.1. The new type of protection structure and its tractor attachment must
have received EEC component type-approval.
5.2. The new type of protection structure must be 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 must corre-
spond 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-approval 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 intended to be
mounted on the type of tractor for which type-approval is requested,
the checks laid down in 2 and 3 are not applicable.1986L0298 — EN — 04.01.1990 — 001.001 — 42
