Draft supplemental documents to accompany the submission of the proposed
global technical regulation on pneumatic radial tyres for passenger and light truck (commercial) vehicles.

Proposal to include wet grip adhesion provisions for C2 and C3 tyre categories.

Proposal concerning the final report following upon the draft prepared by France on the development of a global technical regulation concerning uniform provisions for pneumatic radial tyres for passenger and light truck (commercial) vehicles.

European countries are considering new requirements to require the fitment of snow tyres for use in severe snow conditions on specific axles of heavy duty vehicles. New tyres are approved under UN R117; however, a large percentage of heavy duty vehicles are fitted with retreaded tyres which are outside the scope of UN R117. This proposal would transpose the relevant requirements for new snow tyres into UN R109 in order of avoid the exclusion of retreaded tyres from such applications/markets.

Proposed amendments to update the documents, especially with reference to obsolete deadlines and timelines, in light of the recent finalization of the GTR text.

Presentation supporting documents GRRF/2015/25, /29, and /32 proposing to:
a) Align definitions and content of UN tyre regulations;
b) Include a definition of “manufacturer” extracted from the resolution “R.E.3”;
c) Adopt a common definition and use of the terms “Manufacturer’s name”, “Brand name”, “Trademark”, “Trade description” and “Commercial name” and their links; and
d) Add information in the certificate to enable approval authorities to more easily understand the products the certificate addresses.

Proposal to improve the wording of the draft amendment on lane-keeping assistance systems, based on document GRRF-79-04.

The current text of UN R54 does not encompass the case where a tyre designed for a “special” application can also fulfil the definition of a “snow” tyre. This proposal would allow for such tyres to be marked with the inscription M+S, M.S, or M&S while remaining in the category of use “special”.

Presentation on French government views on the approval of automated steering at speeds above 10 km/h under UN Regulation No. 79. The principle recommendation is to restrict amendments to UN R79 to lateral vehicle control as speeds above 10 km/h while setting other work on more advanced capabilities (longitudinal + latitudinal, lane change, passing, etc.) for future separate regulations.

Proposal to amend the consolidated draft amendment to UN R79 to introduce technical requirements for Corrective Steering Functions and Level B1 ACSF under UN R79 (document GRRF/2016/45).

Proposal to simplify the verification of sufficient movement on the balancer (of the compensator) without having to take measurements underneath the trailer in an potentially unsecured position and to correct the text of Annex 12 (Conditions governing the testing of vehicles equipped with inertia (overrun) braking systems). Intention to provide an objective calculation method as part of setting requirements for permissible “differential travel” or swivel.

Proposal to clarify the intent and rationale behind the proposal to simplify the verification of sufficient movement on the balancer without having to take measurements underneath the trailer in a potentially unsafe position.

i) Align the current rules for calculating the dimensional limits in accordance with ISO, all major tyre standards, and as proposed for UN R30, R54, and R75.

Proposal to introduce technical requirements for Corrective Steering Functions (lane departure prevention, lane-keeping assistance (LKAS), steering angle correction, etc.) as defined in the regulation. The proposal offers four options to ensure appropriate approvals of LKAS and related CSF systems until such time as more precise requirements can be defined:

• Option 1 and option 2: Not to grant any type approvals for corrective steering functions until detailed technical requirements for CSF are incorporated into this Regulation.
• Option 3: Amend the definition of CSF as proposed in this document.
• Option 4: Amend the definition of corrective steering functions and to include technical requirements for LKAS as an ASCF of Category B1 as proposed in this document.

In order to have a Regulation on the retreaded tyres with definitions and provisions structured in the same way of those previously introduced in amendments of “new tyres” Regulations, this amendment:

1. indicates that for the purpose of this Regulation “tyres” means “pneumatic tyres” (all text amended accordingly)
2. introduces definitions of:
   • “retreader” copy based on that “manufacturer” in the tyres regulations
   • Brand name", “Trademark”, “Trade description” and “Commercial name” as defined in the tyre regulations
   • Material manufacturer / material supplier
3. takes into account the rounding rules (already approved in the other tyre regulations) for the calculation of width and diameter of the tyres
4. aligns the title and the provisions of the para. 12 related to the names and addresses of Technical Services, Approved Laboratories and administrative Department with their equivalent in the tyres regulations
5. add some information in the certificate to the attention of the Type Approval Authorities for making easier the relationship between this one and the products
6. introduces:
   • In para. 6.4.4.1., the possibility for the material manufacturer or supplier of the pre-cured tread pattern to provide directly to the Type Approval Authority (or Technical Service) all the documents needed to demonstrate the retreaded tyres produced with this pre-cured tread pattern fulfil the requirements of paragraph 7.2. in order to be classified as a “snow tyre for use in severe snow conditions”
   • In para. 7.1.4.2. a new table of tolerances with the objective to properly take into account the requirements for size designations in Annex 5 in addition to what already expressed. The maximum overall width has been taken from the international Tyre Standard ETRTO and Tire and Rim Association.

In order to have a Regulation on the retreaded tyres with definitions and provisions structured in the same way of those previously introduced in amendments of “new tyres” Regulations, this amendment:

1. Indicates that for the purpose of this Regulation “tyres” means “pneumatic tyres”, so all the text has been reviewed
2. Introduces a definition of :
   • “retreader” copy based on that “manufacturer” in the tyres regulations
   • Brand name", “Trademark”, “Trade description” and “Commercial name” as defined in the tyre regulations
   • Material manufacturer / material supplier
3. Takes into account the rounding rules (already approved in the other tyre regulations) for the calculation of width and diameter of the tyres
4. Aligns the title and the provisions of the para. 12 related to the names and addresses of Technical Services, Approved Laboratories and administrative Department with their equivalent in the tyres regulations

Proposal to enable the use of alternate colors (per footnote 18 of Table 1 and in line with ISO Standard 2575) for certain lighting tell-tales in order to indicate light source failures in response to the proposals for light failure indicators under UN Regulations Nos. 7, 48 and 87 (GRE/2016/7, GRE/2016/12 and GRE/2016/17) as adopted by GRE. This proposal anticipates use of the same approach in response to plans for additional failure indication requirements for other lighting regulations.

Proposal to allow for the use of natural gas refrigeration systems to vehicles propelled by natural gas (CNG or LNG). This proposal addresses a new, environmentally friendly natural gas fuelled refrigeration system for trucks with refrigerated loads that already are propelled by natural gas. Currently paragraph 18.1.7.1 allows heating systems to be fitted on vehicles to heat the passenger compartment and/or the load area of a vehicle, however, the same provision omits cooling systems that are used on trucks for the carriage of loads requiring refrigeration.

Proposal for editorial corrections to align the definition on plastic glazing between the original English version and the French translation as well as of the communication annex on principal/secondary characteristics for laminated-glass windscreens.

Proposal to align the communication form with with the scope of the Regulation regarding vehicle categories (adding category L).

In the English version of UN Regulation No. 34, the provisions for lateral collision are referenced in para. 1.2. of the scope and in para. 9 of Part II on vehicle tests, but (unlike in the French translation) they are not mentioned in para. 5.10. on the test requirements for liquid fuel tanks. This proposal aims to align the English version to French text of the Regulation with regard to the test provisions for side impacts.

Proposal to exempt any heaters (and not only combustion heaters as in the current text) located outside the passenger compartment and using water as a transfer medium are deemed to comply with the annexes on air quality and temperature.

Discussion of the evolution of UN R73 with a proposal to update load requirements for lateral protection devices:

• Application of a force of 3kN perpendicular to the device (as currently defined)
• Max. strain under loading at 90mm over the 250mm most rearwards part
• Max. strain under loading at 450mm on the other parts.

Proposal to amend geometrical criteria and installation provisions for lateral protection barriers in order to improve their performance with regard to vulnerable road users (e.g., lateral contact with a motorcycle or its rider(s)).

Proposal to update the horizontal static force requirement for lateral protection devices to 3 kN and the deflection under load criteria to 90 mm over the rearmost 250 mm of the device and 450 mm over the remainder of the device. The purpose is to reduce the risk of running over a person (e.g., a motorcycle rider) during a lateral collision.
