UN R34 — 04 series of amendments

Paragraph 1.2. now reads “Part II (vacant)”. Part I now also covers the installation of liquid fuel tanks in M1 and N1 vehicles up to 2.8 tonnes total permissible mass. Before this series, Part II-1 applied at the request of the manufacturer and covered fire risks in a frontal, lateral or rear collision. Part II-2 covered rear collisions of M1 and N1 vehicles up to 2.8 tonnes total permissible mass, with tanks approved to Part I or IV.

Part II-1 and Part II-2, on the approval of vehicles with regard to the prevention of fire risks in the event of collision, are deleted. Paragraphs 7. and 9. now read “(Vacant)”, and paragraph 8.1.1. reads “(vacant)”. Old paragraph 9. had the vehicle tests: frontal, lateral and rear-end impacts, with requirements on fuel leakage, fire and the battery. Annexes 3 and 4, the frontal collision test against a barrier and the rear-end collision test, now read “(vacant)”. Old paragraph 14.2. is deleted. It said that a variant tested to Part II, with an unladen mass within ± 20 per cent of the tested vehicle, was not a modification.

Paragraph 13.1. now requires M1 and N1 vehicles up to 2.8 tonnes total permissible mass to also comply with paragraph 8. Before, paragraph 13.1. did not refer to paragraph 8. At the request of the manufacturer, paragraph 8. may be applied to vehicles of categories M2, N2, M3, N3 and O. The same applies to M1 and N1 vehicles over 2.8 tonnes, and to other categories up to 2.8 tonnes. In the vehicle type definition, paragraph 4.2.1. now names the structure, shape, dimensions and materials of the tank(s). New paragraph 4.2.3. adds the characteristics and siting of the fuel feed system.

Paragraphs 2.1., 2.1.1., 3.1. and 3.1.1. no longer refer to Part II, and paragraph 2.1.2.1. no longer refers to paragraph 7.2. Paragraph 2.1.2.4. now asks for a diagram of the electrical installation without the condition “For application pursuant to Part II”. In paragraph 3.1.4.2., the approval mark symbols “RII-1” and “RII-2” are deleted. Paragraphs 3.1.2., 3.2.2. and 3.3.2. now assign approval numbers in accordance with Schedule 4 of the Agreement (E/ECE/TRANS/505/Rev.3). Before, the first two digits of the approval number gave the most recent series of amendments at the date of issue. Under paragraphs 3.1.3., 3.2.3. and 3.3.3., the notice of approval or refusal now uses the form only, without the drawings.

Former paragraph 14.3. is now paragraph 14.2., and it covers notice of confirmation, extension or refusal of approval. Under new paragraph 14.3., the Type Approval Authority that issues an extension must assign a series number to each communication form for it. Conformity of production procedures must now comply with Schedule 1 of the Agreement (E/ECE/TRANS/505/Rev.3), in place of Appendix 2. Paragraphs 15.2. and 15.3. are deleted. Paragraph 16.1. no longer refers to the checks of paragraph 9. A withdrawal is now notified with a copy of the approval form that carries the signed and dated annotation “APPROVAL WITHDRAWN” (para. 16.2.).

In the communication form, item 9 on the impact tests is now “(vacant)”, and the line on frontal, lateral and rear collision is deleted. Item 19 now says that the index to the information package lodged with the Type Approval Authority is attached. In Annex 2, the model approval marks now show approval numbers that start with 04 and refer to the 04 series of amendments. Model B is now “(vacant)”, and the model marks with Part II-1 or Part II-2 are deleted. One footnote with the text “The second number is given merely as an example.” is deleted.

From the entry into force of the 04 series, no Contracting Party applying this Regulation may refuse to grant or accept 04 series approvals. From 1 September 2026, Contracting Parties applying this Regulation need not accept approvals to the preceding series first issued after that date (para. 17.2.). They must continue to accept approvals to the 02 and 03 series first issued before 1 September 2026 (para. 17.3.). They may grant approvals to any preceding series, and must continue to grant extensions of existing approvals to any preceding series (paras. 17.4. and 17.5.). Contracting Parties that start to apply this Regulation after the latest series enters into force need not accept approvals to preceding series (para. 17.6.). The old paragraphs 17.2. to 17.6. on the 02 series and its Supplement 3 are deleted.
