Illustrations to accompany the CLEPA proposal concerning conspicuity markings for commercial vehicles (document GRE-67-28).

Analysis raising concerns regarding the proposal to establish photometric requirements for Class B1 based on average real performance of present Class B (halogen/LED) without reference to design specifications such as the luminous flux of light source.

Proposal to improve the proposal submitted by the experts from France and Germany to allow under specified conditions the use of manufacturer logos inside the illuminant surface of a signalling lamp.

Proposal to update UN R27 in accordance with technological progress by establishing provisions for the use of fluorescent retro-reflective strip, enabling the consolidation of currently separate fluorescent (daytime) and retro-reflective (nighttime) striping.

Combined GTB and CLEPA proposal, superseding documents GRE/2011/46 and GRE/2012/25, to update UN R27 in line with technological progress and performance-based methodologies. The main changes are:

a) Revised provisions to combine color boundaries for the night time color,
b) Replacement of Illuminant C with Illuminant D65 in the measurement of fluorescent materials,
c) Alternative methods introduced for instrumental measurement of the fluorescent color,
d) New Annex 10 to replace reference to ISO 105,
e) Clarification of the wind test (Annex 5),
f) Standardization of the test surface representing the road,
g) Simplification of the test device for clearance to the ground in Annex 3,
h) Amendment of COP requirements, and
i) 36-month transitional period in a new paragraph 14.

Proposal to introduce new Class 5 devices made solely of retro-reflective plates with chevron type pattern to be applied to special utility vehicles or trailers not regularly covered by standard rear marking plates in order to harmonize existing national requirements.

Proposal to introduce a new Class F marking designed with chevron-type pattern to be applied to special utility vehicles or trailers not normally covered by standard contour marking materials in order to harmonize national requirements making use of such markings.

This proposal introduces new class 5 devices made solely of retro-reflective plates with chevron type pattern to be applied to special utility vehicles or trailers not regularly covered by standard rear marking plates. The amendment also seeks to harmonize the text to cover various national requirements.

This proposal introduces new class F marking materials designed with chevron type pattern to be applied to special utility vehicles or trailers not ordinarily covered by standard contour marking materials. The proposal also attempts to harmonize a number of national requirements.

Proposal to ensure that the introduction of the new class F marking materials does not conflict with the mandatory requirements for existing class C materials. Class F markings are designed with alternate stripe pattern to be applied to special utility vehicles or trailers not regularly covered by standard contour marking materials requires amending the definitions.

Recommendations by AECC, CLEPA, EUROMOT, and OICA for minimum quality attributes of market fuels (i.e. gasoline and diesel) to be introduced “in parallel, and at the same time, to complement the level of motor vehicle and non-road mobile machinery pollutant emission standards that a country or region may be considering to introduce”.

Revised recommendations by AECC, CLEPA, EUROMOT, and OICA, pursuant to discussions during the GRPE-68 session, for minimum quality attributes of market fuels (i.e. gasoline and diesel) to be introduced “in parallel, and at the same time, to complement the level of motor vehicle and non-road mobile machinery pollutant emission standards that a country or region may be considering to introduce”.

Proposal to ensure that all replacement pollution control devices conform with the intent of UN R49 and to align UN R49 in this regard with Regulation (EU) 2016/1718. CLEPA proposes the establishment of a new annex under UN R49-05 R.49-05 to restrict the approval of a replacement device to one that “enables the engine and vehicle to comply with the rules with which it was originally in compliance”.

This proposal intends to establish a definition for ‘Hydrogen ICE vehicle’ and the related method for ‘trip validation’

This document aims at transposing UN GTR 24 into a new UN Regulation on uniform provisions concerning the approval of non-original and identical replacement brake parts with regards to particle emissions.

This document is also available with tracked changes.

Additional validation work to support the the proposal to:
• Provide new evidence based on additional analysis.
• Compare MAW window validation and RDE results using work, fuel, and CO₂-based parameters.

The objective of this document is to provide recommendations for the minimum quality of market fuels (i.e. gasoline and diesel) that should be introduced concurrently with the corresponding emissions standards. They complement the motor vehicle and NRMM pollutant emission standards that a country or a region may be considering to introduce.

Proposal to establish approval requirements for the particle emissions of replacement brake pads (based on the laboratory method established by GTR 24).

CLEPA draft proposal to amend Regulation No. 13 to specify uniform requirements for towing trailers and motor vehicles which may tow more than one trailer (road train combinations).
