The Russian Federation Proposal for Amendment 2 to the Consolidated Resolution on the Construction of Vehicles (R.E.3)
Informal document GRB-57-26(57th GRB, 5-7 February 2013,agenda item 12)
The proposal concerns:
Specifications on category G for road tractors
Specifications on the formulation of requirements on noise
Modification of the method of measuring vehicle internal noise
Recommended permissible levels of vehicle internal noise
Background
At the 55th and 56th GRB sessions the proposals of the Russian Federation concerning the Consolidated Resolution on the Construction of Vehicles R.E.3 (ECE/TRANS/WP.29/78/Rev.2) had been considered. The Russian expert introduced document ECE/TRANS/WP.29/GRB/2012/12. GRB decided to resume discussion on this subject at its February 2013 session, awaiting revised proposals by the Russian Federation and reproducing separately the different subjects of the said document.
Specifications on category G for road tractors
Parameter Road Tractor Tractor-lorry-trailer combination
At least half the wheels are driven Two axles from three
Two axles from five
(Two axles from six)
At least one differential mechanism Yes Yes
Climb a 25 per cent gradient Yes ???
Approach angle must be at least 25 0 26 0 26 0
The departure angle must be at least 25 0 48 0 8 0
At ramp angle must be at least 25 0 30 0 20 0
The ground clearance under the front axle must be at least 250 mm
More then 250 mm More then 250 mm
The ground clearance under the rear axle must be at least 250 mm
More then 250 mm More then 250 mm
The ground clearance between the axlts must be at least 300 mm
230 230 or 280 ???
Paragraph 2.8.2.2.: The text of the UN R.E.3 does not specify, how to test the road tractor for towage semitrailers (with or without semitrailer) in order to refer them to G category vehicles. It may be possible to test a single tractor, which in practical conditions practically is not used on roads, and erroneously refer it to G category, although the basic designation of a trailer is to tow semitrailers on public roads. The proposed modification excludes possible reference of tractors to G category vehicles.
Specifications on the formulation of requirements on noise
Paragraph 3.: The proposal specifies that the column "Tractors" concerns T category vehicles and corrects the heading of the UN Regulation No. 117.
Paragraph 4.: The proposal gives more details of the scopes of UN Regulations concerning vehicle noise.
Paragraph 8.4, 8.4.4., 8.8.1.2., 8.8.2.1.1., 8.8.2.1.3., 8.8.2.1.4.: Editorial corrections providing for uniformity of the provisions.
Paragraph 8.8.2.1.2. The specification applies to noise emitted by three-wheeled vehicles in use. Also it is proposed to specify vehicle categories as established by the R.E.3.
Modification of the method of measuring vehicle internal noise
This informal document includes the amendments concerning: Means of measurement of internal noise; Requirements to a test site; Requirements to test samples; Test conditions and installation of microphones; Analysis of test results
Paragraph 8.38. and its subparagraphs.:The present text contained in UN R.E.3. is based on the ISO 5128 standard, developed in 1980s. This proposal concerns both specifications of requirements of the measuring equipment, and changes to the test technique due to the development of vehicle design in the last decades.

* Note: The permissible noise levels for all-wheel drive motor vehicles of categories M2G, M3G, N1G, N2G, and N3G may be exceeded by not more than 1 dB (A).
Paragraphs 8.8.1. and 8.8.1.3.: These paragraphs recommend limit values on vehicle internal noise. These data will be useful in a technological level assessment of internal noise taking into account the technique specified in paragraph 8.38. Limit values are set for both the driver working space and for the passenger compartment. The proposed values are based on the statistics of a considerable number of measurements from the Russian Federation at the time of vehicle homologation within the framework of the national vehicle certification system. Several editorial corrections are also introduced.
THANK YOU!
