Q1What changed24 changes
New paragraph 5.1.3.5. on the electric power train
New paragraph 5.1.3.5. requires the electric power train to meet UN Regulation No. 100, as amended at least by the 03 series of amendments. Measures must be taken to prevent any danger to the load by heating or ignition. A note says that electric power trains must not be used for EX and FL vehicles. Paragraph 5.1.3.5. likewise applies to hybrid vehicles that include an electric power train in the mechanical driveline of an internal combustion engine. The table in paragraph 5.1. has a new row for paragraph 5.1.3.5., Electric power train. Former paragraphs 5.1.3.5. to 5.1.3.6.1. are renumbered as paragraphs 5.1.3.6. to 5.1.3.7.1.
Electrical installation: exception for the electric power train (para. 5.1.1.1.)
An exception now covers the electric power train in compliance with the technical provisions of UN Regulation No. 100, 03 series or later. The rest of the electrical installation must meet the provisions of paragraphs 5.1.1.2. to 5.1.1.9. in accordance with the table of paragraph 5.1. Before this supplement, the electrical installation as a whole had to meet these provisions. A new footnote gives the full title of UN Regulation No. 100.
ISO 19642 standards for cables (paras. 5.1.1.2.1. and 5.1.1.2.2.)
The cables in paragraph 5.1.1.2.1. may now also be in conformity with ISO 19642-3:2019, ISO 19642-4:2019, ISO 19642-5:2019 or ISO 19642-6:2019. Before this supplement, the cables had to be in conformity with ISO 6722-1:2011 including its Corr. 01:2012 or ISO 6722-2:2013. Paragraph 5.1.1.2.2. now also accepts multicore cables in conformity with ISO 19642-7:2019, ISO 19642-8:2019, ISO 19642-9:2019 or ISO 19642:10:2019 as additional protection. Multicore cables in conformity with ISO 14572:2011 stay in the list.
Electric regenerative braking systems (para. 5.1.2.1.)
Paragraph 5.1.2.1. has a new sentence for vehicles equipped with an electric regenerative braking system. These vehicles must fulfil all relevant technical requirements of UN Regulation No. 13 (11 series of amendments or later), as applicable.
Hybrid vehicles: new notes to paragraphs 5.1.3.2. and 5.1.3.3.
Paragraph 5.1.3.2. now likewise applies to fuel tanks and cylinders used for two kinds of hybrid vehicles. Paragraph 5.1.3.3. now likewise applies to the same two kinds of hybrid vehicles. One kind includes an electric power train in the mechanical driveline of the internal combustion engine. The other kind uses an internal combustion engine to drive a generator to energize the electric power train.
MEMU vehicles and the 06 series of amendments (para. 5.1.)
Vehicles approved to the EX/III requirements of this Regulation, as amended by the 06 series of amendments, are deemed to comply with the MEMU requirements. Before this supplement, the text referred to the 05 series of amendments. Paragraph 5.1. now refers to “the table overleaf” instead of “the table below”.
