Corrections to the proposal for Supplement 3 to the 06 Series of UN R48

Further corrections and clarifications to the proposal to clarify and simplify the transitional provisions of the 06 series of UN R48.

Proposal to extend the proposed amendment to introduce “interdependent lamps” to the 04 and 05 series of amendments to Regulation No. 48.

Proposal to retroactively extend the clarifications to the definitions and requirements associated with the installation of “single lamps”, “lamps marked D” and “interdependent lamps” to the 04 and 05 series amendments to Regulation No. 48.

Proposal to extend to the the 04 and 05 series amendments to Regulation No. 48 the proposed reduction in the minimum speed for activation of E-class passing beams from 70 km/h to 60 km/h and to prescribe clear alternatives to either detect motorway conditions with sensors or only activate the E mode above a speed of 110km/h.

Following discussions with OICA, GTB proposes improvements to the definitions and requirements associated with the installation of “single lamps”, “lamps marked D” and “interdependent lamps”.

Status report on the GTB working group establish with SAE to assist NHTSA in the development of test protocols for adaptive driving beam (ADB) headlamps under FMVSS 108.

Status report on efforts to resolve concerns related to automatic headlamp leveling provisions and their impact on visibility and on-coming driver glare.

Brief presentation raising question over the necessity to have triangular reflectors on the rear of large trailers and seeking greater flexibility in such rear reflectors.

During the 71st session of GRE, the experts from GTB presented the outcome of a study on visibility and glare of automotive low beam headlamps; see informal document GRE-71-32. The study concentrated on levelling in relation to load. The major objectives of the study were to improve the understanding of different factors that influence visibility and glare and to identify results of the study that might reveal alternatives for automatic static levelling. The deciding factors in headlamp glare have been determined to be the vehicle pitch angle, loading conditions and initial headlamp aim. Therefore, this proposal looks at replacing the light source technology and the light source 2,000 lm criterion in UN Regulation No. 48 as criteria for the requirement for automatic levelling with performance requirements based upon these deciding factors.

Front fog lamps may be reciprocally incorporated with the main beam and in some cases, it is required to switch off the front fog lamp when the main beam is operated to avoid overheating of the device. In this case, Regulation No. 19 requires a “/” in the approval marking. However, the current text in paragraph 6.3.7 of Regulation No. 48 requires that “it shall be possible to switch the front fog lamps ON and OFF independently of the main-beam headlamps”. This proposal is intended to remove the conflict between the texts of the two regulations. This proposal supersedes and replaces document GRE/2014/22 and has been prepared to remove ambiguities identified in the previous proposal.

Supplemental presentation in support of document GRE/2015/3: Proposal for Supplement 9 to the 05 series of amendments and Supplement 7 to the 06 series of amendments to Regulation No. 48.

In November 2013, the GTB proposal for the simplification of the transitional provisions of Regulation No.48 was adopted by WP29 at its 161st session as Supplement 3 to the 06 series. Associated with this proposal was a decision that the secretariat would produce full consolidations of the 04 /05/06 series and these were introduced as Revisions 7, 8 and 9 respectively.

At that time, it was also agreed that GTB would produce a consolidation of the 03 series that would be posted on the UNECE Website for reference purposes. It was considered that a consolidation of the final (frozen) state of the 03 series would be useful as a reference for the vehicle manufacturers who may continue to apply for extensions to the original type approvals according to the 03 series. However, with the development of IWVTA and the revision of the 1958 Agreement, this consolidation may have value as “a version of a UN Regulation” as defined in the draft Revision 3.

This document is a consolidation produced by the experts of GTB and incorporates all valid text up to, and including, Supplement 5 to the 03 series of amendments (Date of entry into force: 09 December 2010). This consolidation is submitted to GRE for verification and for possible introduction to the UNECE website.

Correction to the proposal for a collective amendment to Regulations Nos. 7, 23, 38, 48, 77, 91 and 119. Since the cornering lamp projects a beam to the left and right of the reference axis, it is not relevant to check the photometric values in the reference axis (HV). Therefore, the test point at 2.5°D, 45°L or R shall be used.

Revised proposal (removing the section on UN R48 and incorporating corrections noted in document GRE-76-07) to refine the requirements for lamps equipped with several light sources, including in systems fitted with an operating tell-tale that indicates the failure of any one of these light sources. In the case of failure of any one light source in a single lamp containing more than one light source, either the light intensity must comply with the minimum intensity required in the table of standard light distribution in space or, for lamps used in systems where a tell-tale indicates the failure of any one of the light sources, the light intensity in the axis of reference must be at least 50 per cent of the minimum intensity required. This collective amendment addresses Regulations Nos. 7, 23, 38, 77, 91 and 119. The proposals concerning UN R48 will be resubmitted for consideration during the 77th GRE session.

During October 2016, GRE-76 adopted collective amendments (GRE/2016/31) to align the requirements of lamp regulations (7, 23, 38, 48, 77, 91 and 119) to guarantee the conformity of the lamp in case of any failure or the mandatory indication that a failure had occurred. This means that when a failure indication signal is provided by the lamp, the vehicle shall be equipped with a tell-tale indicating the failure. Thus, amendments were proposed for Regulation No. 48 to specify the modes of displaying the corresponding failure (see GRE/2016/7). Subsequently, some GRE experts requested GTB to clarify the text of its proposal. This proposal amends UN R48 with respect to all lamps affected by GRE/2016/31 to include the failure indication requirement. The proposal does not apply to the failure indication requirements already in UN R 48 prior to the last (76th) GRE session.

Explanation of changes between the proposal to introduce requirements for light emitting diode (LED) substitute light sources into Regulations Nos. 48, 53, 74 and 86 presented at GRE-77E/2017/4) and the revised proposal (GRE/2017/22) submitted for consideration at GRE-78.

Proposal to address inconsistencies, clarify text, and correct terminology in Regulation No. 48:

• para. 5.7.2.1. editorial alignment of text with current terminology
• replace undefined “effective outlet” terminology with defined “apparent surface” reference
• reintroduction of missing reference to “transverse plane” in paras. 5.10.1. and 5.10.2.
• para. 6.2.9. and related subsequent paragraphs to clarify the application of the 2000 lumen criteria
• para. 6.26.9.2. to correct a cross-reference with UN R23.

The proposal opens the opportunity to project driver assistance symbols on the road ahead the vehicle as part of the Adaptive Driving Beam by introducing angular limits for the placement of these projections as well as luminous intensity limits in order to guarantee a good perceptibility of the symbols for the driver at night time without distracting other road users.
