COUNCIL DIRECTIVE
of 28June 1977
on the approximation of the laws of the Member States relating to
the roll-over protection structures of wheeled agricultural or
forestry tractors
(77/536/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,Having regard to the opinion of the European Parliament (
1),
Having regard to the opinion of the Economic and Social Committee (2),
Whereas the technical requirements with which 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 Council Directive 74/150/EEC of 4 March 1974 onthe approximation of the laws of the Member States relating to the type-approval of wheeled agricultural or forestry tractors (
3), to be applied in
respect of each type of tractor;
Whereas a harmonized component type-approval procedure for roll-over
protection structures and their attachment to the tractor makes it possible
for each Member State to check compliance with the commonconstruction and testing requirements and to inform the other MemberStates of its findings by sending a copy of the component type-approvalcertificate completed for each type of roll-over protection structure and
its attachment to the tractor; whereas the placing of an EEC-component
type-approval mark on all structures manufactured in conformity withthe approved type obviates any need for technical checks on thosestructures in the other Member States;
Whereas common requirements concerning other elements and char-
acteristics of the roll-over protection structure, in particular thoseconcerning the dimensions, doors, safety glass, devices to preventcontinuous rolling if the tractor overturns, and protection of passengers,
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 forthis reason it is necessary to introduce the obligation for tractors coveredby this Directive to be fitted with roll-over protection structures;
Whereas the approximation of the national laws relating to tractors
entails reciprocal recognition by Member States of the checks carriedout by each of them on the basis of the common requirements,
HAS ADOPTED THIS DIRECTIVE:
Article 1
1. Each Member State shall grant EEC component type-approval for
any type of roll-over protection structure and its tractor attachmentwhich satisfies the construction and testing requirements laid down inAnnexes I, II, III, IV and V hereto.1977L0536 — EN — 01.01.1995 — 005.001 — 2

2. The 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 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 authorized representative, an EEC component type-approval markconforming 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 structureswhich have been component type-approved pursuant to Article 1 andother 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 relatingto their construction if they bear the EEC component type-approvalmark.
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
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 ofthe component type-approval certificates, an example of which is givenin Annex VII, completed for each type of roll-over protection structure
which they approve or refuse to approve.
Article 5
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 take the
necessary measures to ensure that production models conform to the
approved type. The competent authorities of that State shall advise thoseof the other Member States of the measures taken which may, isnecessary, where there is serious and repeated failure to conform, extendto withdrawal of EEC component type-approval. The said authorities
shall take the same measures if they are informed by the competent
authorities of another Member State of such failure to conform.
2. The competent authorities of the Member States shall within one
month inform each another of any withdrawal of EEC component type-
approval and of the reasons for any such measure.
Article 6
Any decision taken pursuant to the provisions adopted in implementa-
tion of this Directive to refuse or with-draw 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 thereasons on which it is based. Such decision shall be notified to the partyconcerned, who shall at the same time be informed of the remediesavailable to him under the laws in force in the Member States and of thetime limits allowed for the exercise of such remedies.1977L0536 — EN — 01.01.1995 — 005.001 — 3

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 hazarad 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 74/150/EEC (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 specialized
components.
2. APPARATUS AND EQUIPMENT2.1.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.1977L0536 — EN — 01.01.1995 — 005.001 — 8
▼B
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-overprotection 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: ±
2º.1977L0536 — EN — 01.01.1995 — 005.001 — 9

during the tests.
3.1.3. Removal ofnon-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 ofimpacts

ANNEX III
TEST PROCEDURES
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 20º 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 20º 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:
H¼125þ0/C1020 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 20º 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 the1977L0536 — EN — 01.01.1995 — 005.001 — 12
▼B
point of impact at the moment of maximum deflection, the supporting
chains or wire ropes remaining at an angle of 20º 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:
H¼125þ0/C1020 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 angleof 30 ± 3º 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.1977L0536 — EN — 01.01.1995 — 005.001 — 13
▼B
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:
H¼125þ0/C1150 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.1977L0536 — EN — 01.01.1995 — 005.001 — 14
▼B
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 20º 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 20º 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.1977L0536 — EN — 01.01.1995 — 005.001 — 15
▼B
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:
H¼2/C1165/C210/C08/C2WL2or H¼5/C173/C210/C02/C2I
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/m
2).
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 20º 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 20º 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:
H¼125þ0/C1020 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 the1977L0536 — EN — 01.01.1995 — 005.001 — 16
▼B
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.
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 ± 3º to the horizontal. Its length shall be 20 to 25 times itsthickness 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:
H¼125þ0/C1150 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 isdeflected 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 of1977L0536 — EN — 01.01.1995 — 005.001 — 17
▼B
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 down-
wards 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 suface, 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.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:1977L0536 — EN — 01.01.1995 — 005.001 — 18
▼B
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.1977L0536 — EN — 01.01.1995 — 005.001 — 19
