MEASUREMENTS TO BE MADE ON THE VEHICLE Sample Clauses
The "Measurements to be Made on the Vehicle" clause defines the requirements and procedures for conducting specific measurements or tests on a vehicle as part of a contract or agreement. This clause typically outlines what parameters must be measured—such as emissions, fuel consumption, or performance metrics—and may specify the methods, equipment, and conditions under which these measurements are to be taken. By establishing clear guidelines for vehicle measurements, the clause ensures consistency, accuracy, and fairness in evaluating whether the vehicle meets contractual or regulatory standards.
MEASUREMENTS TO BE MADE ON THE VEHICLE. 6.1. To enable the simplified test described in Annex 7 to be carried out, the deceleration time history of the structure shall be determined on the basis of the value of the longitudinal accelerometers at the base of the "B" pillar on the struck side of the vehicle with a CFC of 180 by means of data channels corresponding to the requirements set out in Annex 8;
6.2. The speed time history which will be used in the test procedure described in Annex 7 shall be obtained from the longitudinal accelerometer at the "B" pillar on the struck side. DETERMINATION OF PERFORMANCE CRITERIA
1. HEAD PERFORMANCE CRITERION (HPC)
1.1. This criterion is considered to be satisfied when, during the test, there is no contact between the head and any vehicle component.
1.2. If that is not the case, a calculation of the value of HPC is made, on the basis of the acceleration (a), measured according to paragraph 5.2.1. of Annex 3, by the following expression: HPC = (t2 − t1 ⎢⎣ t2 2 t 1 1 − t ∫ t1 ⎤2.5 adt⎥ ⎥⎦ in which:
1.2.1. the term "a" is the resultant acceleration measured according to paragraph 5.2.1. of Annex 3 and is measured in units of gravity, g (1 g = 9,81 m/s2);
1.2.2. if the beginning of the head contact can be determined satisfactorily, t1 and t2 are the two time instants, expressed in seconds, defining an interval between the beginning of the head contact and the end of the recording for which the value of HPC is maximum;
1.2.3. if the beginning of the head contact cannot be determined, t1 and t2 are the two time instants, expressed in seconds, defining a time interval between the beginning and the end of the recording for which the value of HPC is maximum;
1.2.4. values of HPC for which the time interval (t1 - t2) is greater than 36 ms are ignored for the purposes of calculating the maximum value.
1.3. The value of the resultant head acceleration during forward impact which is exceeded for 3 ms cumulatively is calculated from the resultant head acceleration measured according to paragraph 5.2.1. of Annex 3.
2. NECK INJURY CRITERIA (NIC)
2.1. These criteria are determined by the compressive axial force, the axial tensile force and the fore/aft shear forces at the head/neck interface, expressed in kN and measured according to paragraph 5.2.2. of Annex 3 and by the duration of these forces expressed in ms.
2.2. The neck bending moment criterion is determined by the bending moment, expressed in Nm, about a lateral axis at the head/neck interface and measured according ...
