UN R83 Supplement 9 (07 series) · UNECE Regulation No. 83 (ECE R83) — Uniform provisions concerning the approval of vehicles with regard to the emission of pollutants according to engine fuel requirements.
UN R83 — Supplement 9 to the 07 series of amendments
Supplement 8 → 9
- What changed
- Annex 7 and its Appendix 1 now allow an alternative equation for variable volume enclosures, at the choice of the manufacturer.
- The time limits in footnote 7 to Table A (E10 and B7 fuels) and in footnote 2 to Table 1 (particulate number limit) are deleted.
- In Annex 7, the pressure recording system now needs an accuracy within ± 0.3 kPa and a resolution of 0.025 kPa.
- Why
- OICA proposed to clarify the relationship between approval levels, reference fuels and PN limits for PI vehicles. The proposal says footnotes to the test-requirement and emissions-limit tables cause inflexibility in recognising some 07 series approval levels.
- OICA proposed to modify the calculation formulae for evaporative emissions in accordance with changes already agreed in UN GTR No. 19.
- The proposal also includes further minor amendments and corrections that were noted during the drafting of UN GTR No. 19.
Q1What changed41 changes
Reference fuels, particulate number limit and approval characters (para. 5.2., Table A; para. 5.3.1.4., Table 1; Annex 3, Table A3/1)
The time limits in footnote 7 to Table A for E10 and B7 fuels in new type approvals and all new vehicles are deleted. The manufacturer's choice of E5 or E10 and B5 or B7 fuels must now be reflected where applicable in the Table A3/1 approval character. In footnote 2 to Table 1, the time limit "Until three years after the dates specified in paragraphs 12.2.1. and 12.2.2." is deleted. The manufacturer's choice of the footnote 2 limit for PI direct injection vehicles must be reflected where applicable in the approval character. In the emissions standard key to Table A3/1, key A now says "complying with" the preliminary values for particulate numbers and adds "using any applicable reference fuel". Key B now says "complying with" the final particulate number standards for PI vehicles "in the table without reference to footnote 2".
Latest level for mutual recognition and approvals to any level (paras. 12.2.5. and 12.3.1.)
New paragraph 12.2.5.: from the entry into force of this supplement, type approvals according to the characters ZD, ZE and ZF "shall be considered to be the latest level for the purposes of mutual recognition for their respective vehicle categories". Paragraph 12.3.1. now says that Contracting Parties "may grant" approvals instead of "may continue to grant" them. "Any level of this regulation" is now also understood to mean any approval character in Table A3/1.
Calculation of evaporative test results (Annex 7, paras. 6.1. to 6.1.2.; Annex 7, Appendix 1, paras. 2.4. to 2.4.2.)
Annex 7 now has the heading "Calculation of evaporative test results" as paragraph 6.1., and the formula text is in paragraph 6.1.1. New paragraph 6.1.2. gives an alternative to the equation in paragraph 6.1.1. for variable volume enclosures, at the choice of the manufacturer. In Annex 7, Appendix 1, paragraph 2.4. now has the heading "Calculations of evaporative test results" instead of "Calculations". New paragraph 2.4.2. gives an alternative to the equation in paragraph 2.4.1. for variable volume enclosures, at the choice of the manufacturer. The symbol lists now say "fixed volume" instead of "fixed-volume".
Enclosure pressure, pressure recording and humidity measurement (Annex 7, paras. 4.2.1., 4.6.2., 4.9. and 4.9.1.)
Any method of volume accommodation must limit the differential between enclosure internal pressure and barometric pressure to a maximum of ±5 hPa, not ±5 kPa. Paragraph 4.6.2. now requires an accuracy of the pressure recording system within ± 0.3 kPa and a pressure resolution of 0.025 kPa. Before, the accuracy was within ±2 kPa, and the pressure had to be capable of being resolved to ±0.2 kPa. Paragraph 4.9.1. and the heading paragraph 4.9., "Additional equipment", are deleted. Paragraph 4.9.1. required the absolute humidity in the test area to be measurable to within ±5 per cent.
Tests for positive ignition engine-powered vehicles (paras. 5.2.1. and 5.2.2.)
The lists of tests in paragraphs 5.2.1. and 5.2.2. no longer include "Engine power test". The OBD test is now the last item of each list.
Text changes in paragraph 13. and in Appendices 3, 5 and 6
In paragraph 13., the repeated words "or extension or refusal or withdrawal of approval" are removed. A new footnote says: "This communication shall be done via the “343-app”". One sentence is deleted: "The Type Approval Authority shall request the manufacturer to submit a plan of remedial measures to remedy the non-compliance". In Appendix 5, paragraph 2., the information that the manufacturer compiles is now for "paragraph 9. and Appendices 3, 4 and 5 of this Regulation" instead of "this annex". In Appendix 6, paragraph 9.4. now says "refilling" instead of "replenishing". It also says "its certificate of conformity" instead of "the type approval issued for that vehicle type".
Text changes in Annexes 1, 5, 7, 10a and 11
Annex 1, item 3.2.12.2.6.2. now reads "Type and design of particulate trap:". In Annex 5, paragraph 3.1., the word "or" is added between "at least 300 mm" and "into the pipe connecting the exhaust with the sampling bag". In Annex 7, paragraph 5.1.3.3., the fuel tank is filled to "40 per cent capacity" instead of "40 per cent volume". Footnote 3 in Annex 10a now says "the fuelling station equipment or the vehicle (engine)" instead of "equipment of the vehicle". The "Vehicle type" definition in Annex 11, paragraph 2.2. no longer has the word "such". In Annex 11, Appendix 1, paragraph 6.5.3.6., the installation position is subject to agreement of the Type Approval Authority instead of the "administrative department".
Q2Why it changed
- Proposed by
- Expert from the International Organization of Motor Vehicle Manufacturers; expert from the European Commission
- Working party
- GRPE, 78th session (January 2019)
Reasons
OICA proposed to clarify the relationship between approval levels, reference fuels and PN limits for PI vehicles. The proposal says that the footnotes to the tables of test requirements and emissions limits are causing inflexibility. This applies to the recognition of some of the approval levels in the 07 series of amendments. It says that these footnotes were introduced correctly to protect the EU from having to accept vehicle approvals that were not compliant with local legislation. It also says that the EU is currently not subject to mutual recognition in UN Regulation No. 83 because of the WLTP transitional provisions.

“clarifying the relationship between approval levels, reference fuels and particulate number limits for positive ignition engines”
OICA proposed to modify the calculation formulae for evaporative emissions in accordance with changes already agreed in UN GTR No. 19. During the development of UN GTR No. 19, an alternative formula for the calculation of hydrocarbons was introduced. It may be used for variable volume SHED facilities at the choice of the manufacturer. The proposal says that these changes in UN Regulation No. 83 will prevent the need for additional text in UN GTR No. 19.

Proposer's reason (informal document GRPE-78-27)
The proposal says that its amendments provide the flexibility for contracting parties to issue approvals to different levels within the 07 series of amendments. They do this by defining levels within the table of approval characters in Table A3/1. The proposal says that only the final emissions and OBD standards would be subjected to mutual recognition. It says that a contracting party can elect to accept other levels of emissions standards and OBD standards within the 07 series.

Proposer's reason (informal document GRPE-78-22)
For paragraph 5.2.1., the proposal says that the change corrects an error introduced in the 07 series of amendments. It says that engine power is covered by UN Regulation 85.
