UN R10 — 07 series of amendments

A new note to paragraph 1.3. says the immunity levels address one of the external environments to consider for functional safety (for example ISO 26262). New paragraphs 2.26. to 2.28. define “Automated Driving System (ADS)”, “Dynamic Driving Task (DDT)” and “Failure situations”. New paragraphs 2.29. and 2.30. define “Residential environment” and “Non-residential environment” by reference to IEC 61000-6-3: 2020 and IEC 61000-6-4: 2018. New paragraphs 2.31. to 2.33. define AVAS, AECS and “Auxiliary Equipment (AE)”. Paragraph 3.2.8. now says “replacement parts” instead of “spare parts”, and new paragraph 6.10.8. excludes the AC/DC mains portion of trolleybus propulsion systems from this Regulation. Paragraph 5.1. now assigns approval numbers in accordance with Schedule 4 of the 1958 Agreement, and conformity of production now refers to its Schedule 1.

Paragraph 6.3.2.4. is deleted: an FM band signal below 20 dB micro-volts no longer exempts a vehicle from further narrowband testing. For two-wheeled vehicles, a non-conductive insulating support 5 to 20 mm thick must now be used between stand and ground plane. Spectrum analysers and FFT-based instruments that meet CISPR 16-1-1 may now be used for conformity measurements, and for FFT-based instruments “the minimum measurement time shall be 1 s per analysis frequency band (in real-time mode)”. If the CISPR 12 mode (40 km/h) does not activate all traction motors or auxiliary battery charging engines, another steady state mode must be agreed. In Annex 4, the vehicle must be tested in the charging mode configuration (if available on vehicle) that the flowchart of Figure 1 defines. For DC charging, an adjustable current must now be set “to at least 20 per cent of its nominal value or to a minimum of 16 A (if the 20 per cent of its nominal value cannot be achieved in the test facility)”, not “to at least 80 per cent of its nominal value”, unless another value is agreed with the type approval authorities.

For tests to Annex 6, paragraphs 6.4.2.1. and 7.7.2.1. now add a field strength of “10 volts/m rms in over 90 per cent of the 2,000 to 6,000 MHz frequency band” and “a minimum of 8 volts/m rms over the whole 2,000 to 6,000 MHz frequency band”. In the vehicle test, AM now covers 20 to 400 MHz instead of 20 to 800 MHz, and new PM2 and PM3 replace PM. A vehicle counts as a “large vehicle” if it is longer than 12 m and/or wider than 2.60 m and/or higher than 4.00 m. For “large vehicles”, the manufacturer, in conjunction with the Type Approval Authority, may choose alternative methods that use BCI and/or ESA tests to Annex 9. Under new paragraph 2.1.1.5., the immunity test must show that a vehicle with an ADS stays “in a failure safe mode or expected failure operational mode during the test in 50km/h mode or Brake mode”. New paragraph 2.1.1.6. and new tables give test conditions and failure criteria for an AECS according to UN Regulation No. 144 and for AVAS.

Paragraphs 6.8.2.1. and 7.18.2.1. now give ESA immunity test levels for 20 to 6,000 MHz in Tables 2a, 2b, 19a and 19b. From 2,000 to 6,000 MHz, Table 2a gives levels only for the ALSE (10 V/m) and reverberation chamber (7 V/m) methods. In Annex 9, a reverberation chamber test to ISO 11452-11 replaces the 800 mm stripline test; it uses a ground plane unless otherwise specified. Paragraph 6.9.1. now requires ESA immunity tests to ISO 7637-2:2011 for pulses 1, 2a, 2b, 3a and 3b, and to ISO 7637-2:2004 for pulse 4. Pulse 4 is only applicable to ESAs that could be installed in vehicles with internal combustion engines started with a 12V/24V starter motor. Under paragraph 7.18.2.2., an ESA now complies if its charging function, as defined in paragraph 2.3. of Annex 9, does not degrade.

Under paragraph 7.1.3., a vehicle in charging mode should be tested with the manufacturer’s charging harness “in line with flowcharts provided in Annexes 4, 6, 11, 12, 13, 15 and 16”. The sentence that the cable “shall be type approved as part of the vehicle” is deleted. New paragraph 7.5.3. gives limits from IEC 61000-6-4 for specific vehicles, such as buses and heavy duty trucks, that are charged only in non-residential environment. For these vehicles, the manufacturer must state that charging is in non-residential environment only; this information must be made publicly available after type approval. Paragraphs 7.6. and 7.14. are now “No longer applicable”, and Annexes 14 and 20 on wired network port emissions are now “(Reserved)”. Under paragraphs 7.15.2.2. and 7.16.2.2., an ESA now complies if there is no degradation of the charging function, not of “immunity related functions”.

The list of standards in Appendix 1 now gives newer editions of many standards, for example ISO 11452-2 (third edition 2019). New entries include ISO 7637-1, ISO 7637-2 (third edition 2011), ISO 11452-11 (reverberation chamber), IEC 61000-6-4, IEC 61851-21-2 and CISPR 16-1-1. The entry for CISPR 22 is deleted, and ISO/IEC 17025 (third edition 2017) replaces ISO-EN 17025 (second edition 2005). In Appendix 8, the key of Figure 1 now says “P: Port to ESA” instead of “P: Port to Vehicle or ESA”. In the keys of Figures 3 to 5, “Vehicle / ESA HV” is now “ESA HV”. The paragraphs on the DC-charging-AN and the 50 µH / 50 Ω-AMN now say “vehicle/ESA in charging mode” instead of “vehicle in charging mode”.

Under paragraph 13.3.1., no Contracting Party applying this Regulation may refuse to grant or accept 07 series type approvals from “the official date of entry into force of the 07 series of amendments”. From 1 September 2029, Contracting Parties applying this Regulation are not obliged to accept approvals to any preceding series first issued after 1 September 2029. Contracting Parties applying this Regulation must continue to accept 06 series approvals first issued before 1 September 2029 (paragraph 13.3.3.). Under paragraph 13.3.4., Contracting Parties applying this Regulation must also continue to accept 06 series approvals “for vehicles, vehicle systems, equipment and parts which are not affected by the changes introduced by the 07 series of amendments”. Contracting Parties that start to apply this Regulation after the entry into force of the most recent series need not accept approvals to preceding series. Contracting Parties applying this Regulation may grant approvals to any preceding series and must continue to grant extensions of existing approvals to them.
