Measurement Uncertainties informal group proposal to clarify the text and to amend:
Proposal to
Proposal to correct values presented in document WP.29/2020/18 and clarification of “first point of information” application in assessment of BSIS.
Proposal for an amendment to complement the content of working document GRVA/2018/5. The proposal includes amendments to:
Proposal to introduce new and enhanced requirements for the car-to-pedestrian test scenario. These requirements would be phased in from May 2024.
Proposal to improve and clarify the text of the Regulation.
Proposal to insert a minimum luminance gradient as an alternative criteria. The current text requires a certain “asymmetry” of the Light Emitting Area (LEA) in order to ensure a “minimum worst-case gradient”; however, this requirement has been deemed too design-restrictive.
Proposal to correct a paragraph reference (‘3.3.2.2’ in place of ‘3.2.3.2’) and to insert a provision from UN R3 (para. 4.1.2.) unintentionally omitted from the original text.
Proposal to reintroduce the run-up provisions for high-intensity discharge (HID) headlamps that were unintentionally omitted from the original text of UN R149.
Proposal to differentiate light source modules in cases where a signalling device contains more than one different module, to restore the sequential activation of direction indicators of categories 11, 11a, 11b, 11c and 12, which were included in UN Regulation No. 50 but omitted when UN R148 was developed during SLR Stage 1, to delete a footnote indicator, and to delete characters from a figure on the standard light distribution of devices.
