ANNEX II
FRONTAL IMPACT TEST AGAINST A BARRIER
1. PURPOSE
The purpose of this test is to verify whether the vehicle satisfies the requirements set forth in item 5.1 of Annex I.
2. INSTALLATIONS, PROCEDURE AND MEASURING INSTRUMENTS
2.1. Testing ground
The test area shall be large enough to accommodate the run-up track, barrier and technical installations necessary for the test. The last part of the track, for at least 5 m before the barrier, shall be horizontal (slope less than 3 % measured over a length of one metre), flat and smooth.
2.2. Barrier
The barrier shall consist of a block of reinforced concrete not less than 3 m wide in front and not less than 1,5 m high. The barrier shall be of such thickness that its mass is at least 70 tonnes. The front face shall be flat, vertical and perpendicular to the axis of the run-up track. It shall be covered with plywood boards 19 ± 1 mm thick, in good condition. A structure on a steel plate at least 25 mm thick may be placed between the plywood board and the barrier. A barrier with different characteristics may likewise by used, provided that the area of the impact surface is greater than the frontal crash area of the vehicle being tested and provided that it gives equivalent results.
2.3. Propulsion of vehicles
At the moment of impact the vehicle shall no longer be subject to the action of any additional steering or propelling device. It shall reach the obstacle on a course perpendicular to the barrier: the maximum lateral misalignment tolerated between the vertical median line of the front of the vehicle and the vertical median line of the barrier is ± 30 cm.
2.4. State of vehicle
|
2.4.1. |
For the test, the vehicle shall either be fitted with all the normal components and equipment included in its unladen kerb mass or be in such a condition as to satisfy this requirement so far as the components and equipment of concern to the passenger compartment and the distribution of the mass of the vehicle as a whole, in running order, are concerned. At the request of the manufacturer, notwithstanding item 5.1 of Annex I the test may be carried out with manikins in position, provided they do not at any time hinder the movement of the steering mechanism. The mass of the manikins shall not be taken into account for the purposes of the test. |
|
2.4.2. |
If the vehicle is driven by external means, the fuel feed system shall be filled to at least 90 % of its capacity with a non-flammable liquid having a density between 0,7 and 1. All the other systems (brake-fluid reservoirs, radiator, etc) may be empty. |
|
2.4.3. |
If the vehicle is driven by its own engine, the fuel tank shall be at least 90 % full. All other reservoirs shall be filled to capacity. If the manufacturer so desires and the technical service agrees, the fuel feed to the engine may be provided from an auxiliary tank of small capacity. In such case, the fuel tank shall be filled to not less than 90 % of its capacity with a non-flammable liquid of a density between 0,7 and 1. |
|
2.4.4. |
If the manufacturer so requests, the technical service responsible for conducting the tests may allow the same vehicle as is used for tests prescribed by other Directives (including tests capable of affecting its structure) to be used also for the tests prescribed by this Directive. |
2.5. Speed on impact
The speed on impact shall be between 48,3 km/h and 53,1 km/h. However, if the test has been carried out at a higher impact speed and the vehicle has met the requirements laid down, the test shall be considered satisfactory.
2.6. Measuring instruments
The instrument used to record the speed referred to in item 2.5 above shall be accurate to within 1 %.
3. RESULTS
|
3.1. |
To determine the rearward and upward movement of the steering control, a recording ( 3 ) shall be made, during the collision, of the variation in the distance — measured horizontally ( 4 ) and parallel to the longitudinal axis of the vehicle and, vertically, in the direction perpendicular to that axis — between the top of the steering column (and shaft) and a point on the vehicle which is not affected by the impact. The largest value of this variation, taken from the recording, shall be taken as the rearward and upward movement. |
|
3.2. |
After the test, the damage sustained by the vehicle shall be described in a written report; one photograph at least shall be taken of each of the following views of the vehicle:
|
4. CORRECTION FACTORS
4.1. Notation
v : recorded speed in km/h;
m0 : mass of prototype in the state defined in paragraph 2.4 of this Annex;
m1 : mass of prototype with testing apparatus;
d0 : variation in the distance measured during the impact, as defined in item 3.1 of this Annex;
d1 : variation in the distance used to determine the results of the test;
K1 : the greater of (48,3/V)2 and 0,83;
K2 : the greater of m0/m1 and 0,8.
|
4.2. |
The corrected variation D1 used to check the conformity of the prototype with the requirements of this Directive shall be calculated by the following formula:
|
|
4.3. |
A frontal impact test against a barrier is not needed in the case of a vehicle which is identical to the prototype considered as regards the characteristics specified in item 2.2 of Annex I but whose mass m1 is greater than m0, if m1 is not more than 1,25 m0 and if the corrected variation D2 obtained from the variation D1 by the formula D2 = (m1 . D1)/m0 is such as to show that the new vehicle still meets the requirements of item 5 of Annex I. |
5. EQUIVALENT PROCEDURES
|
5.1. |
Alternative tests may be permitted at the discretion of the approval authority provided equivalence can be demonstrated. A report shall be attached to the approval documentation describing the method used and the results obtained or the reason for not carrying out the test. |
|
