to the standard for visible lane markings. The lane-marking layout used for the tests shall be recorded in the test report.
The width of the lane shall be minimum 3.5 m, for the purpose of the tests of this annex.
The test shall be performed under visibility conditions that allow safe driving at the required test speed.
The vehicle manufacturer shall demonstrate, through the use of documentation, compliance with all other lane markings identified in Annex 3 of UN Regulation No. 130. Any of such documentation shall be appended to the test report.
2.2. Tolerances
All vehicle speeds specified for the tests described in this annex shall be met within a tolerance of ±2 km/h.
2.3. Vehicle conditions
2.3.1. Test mass
The vehicle shall be tested in a load condition agreed between the manufacturer and the Technical Service. No load alteration shall be made once the test procedure has begun. The vehicle manufacturer shall demonstrate, through the use of documentation, that the system works at all load conditions.
2.3.2. The vehicle shall be tested at the tyre pressures recommended by the vehicle manufacturer.
2.4. Lateral acceleration
The position representing the centre of gravity, at which the lateral acceleration shall be measured, shall be determined in agreement between the vehicle manufacturer and the Technical Service. This position shall be identified in the test report.
The lateral acceleration shall be measured without taking into account the additional effects due to the movements of the vehicle body (e.g. roll of sprung mass).
3. Tests procedures
3.1. Tests for CSF
The following test applies to CSF functions defined in subparagraph (c) of CSF definition in paragraph 2.3.4.2. of this Regulation.
3.1.1. Warning test for CSF
3.1.1.1. The vehicle shall be driven with an activated CSF on a road with lane markings on each side of the lane. In case of a CSF whose interventions are solely based on the evaluation of the presence and location of lane boundaries, the vehicle shall be driven on a road delimited by the boundaries as declared by the manufacturer (e.g. road edge).
The test conditions and the vehicle test speed shall be within the operating range of the system.
During the test, the duration of the CSF interventions and of the optical and acoustic warning signals shall be recorded.
In the case of paragraph 5.1.6.1.2.1. of this Regulation, the vehicle shall be driven such that it attempts to leave the lane and causes CSF intervention to be maintained for a period longer than 10 s (for M1, N1) or 30 s (for M2, M3, N2, N3). If such a test cannot be practically achieved due to e.g. the limitations of the test facilities, with the consent of the
