[3/] The warning signal may light up again while the vehicle is stationary, provided that it is extinguished before the vehicle speed reaches 10km/h when no defect is present.
[4/] Until uniform test procedures have been agreed, the manufacturers shall provide the Technical Services with their test procedures and results.
[5/] It is understood that devices changing the control mode of the anti-lock system are not subject to paragraph 4.4. if in the changed control mode condition all requirements to  the category of anti-lock systems, with which the vehicle is equipped, are fulfilled.
[6/] Until such test surfaces become generally available, tyres at the limit of wear, and higher values up to 0.4 may be used at the discretion of the Technical Service. The actual value obtained and the type of tyres and surface shall be recorded.
[7/] "Full force" means the maximum force laid down in annex 3 to this Regulation; a higher force may be used if required to activate the anti-lock system.
[8/] The purpose of these tests is to check that the wheels do not lock and that the vehicle remains stable; it is not necessary, therefore, to make complete stops and bring the vehicle to a halt on the low-adhesion surface .
[9/] kH is the high-adhesion surface coefficient
kL is the low-adhesion surface coefficient
kH and kL are measured as laid down in appendix 2 to this annex.
[1/] FMnd and FMd in case of two-axled motor vehicles: these symbols may be simplified to corresponding Fi - symbols.
