UN R94 Supplement 2 (04 series) · UNECE Regulation No. 94 (ECE R94) — Uniform provisions concerning the approval of vehicles with regard to the protection of the occupants, fuel system integrity and protection against electrical shock in the event of a frontal collision.
UN R94 — Supplement 2 to the 04 series of amendments
Supplement 1 → 2
- What changed
- New paragraph 7.1.2.1. says when a change to the vehicle structure or mass requires a repeat of the Annex 3 test.
- New paragraph 7.1.2.2. covers changes to interior fittings only, with the same number of front seats and no mass increase above 8 per cent. For these changes, a simplified test as provided for in Annex 7 and/or a partial test must be carried out.
- Why
- The 04 series of amendments deleted a text that allows tolerances on the vehicle mass and simplified testing.
- The proposal would allow GRSP to decide whether the deletion was intended.
Q1What changed4 changes
Repeat of the Annex 3 test after a structure or mass change (para. 7.1.2.1.)
New paragraph 7.1.2.1. requires a repetition of the test as described in Annex 3 for “Any modification of the vehicle affecting the general form of the structure of the vehicle and/or any increase in mass greater than 8 per cent which in the judgement of the authority would have a marked influence on the results of the tests”. Paragraph 7.1.2.1. was not in the 04 series before this supplement.
Simplified and/or partial test for interior fitting changes (paras. 7.1.2.2. to 7.1.2.2.2.)
New paragraph 7.1.2.2. applies when the modifications concern only the interior fittings. Two more conditions apply: the mass does not increase by more than 8 per cent, and the number of front seats stays the same. In that case, a simplified test as provided for in Annex 7 and/or a partial test must be carried out. The Technical Service defines the partial test in relation to the modifications made. These paragraphs were not in the 04 series before this supplement.

Q3Who is affected
Vehicle manufacturer
- Check each planned modification against the structure and mass conditions in paragraph 7.1.2.1.
- Be ready for a repeat of the Annex 3 test when paragraph 7.1.2.1. applies.
- For changes to interior fittings only, check the mass increase and the number of front seats against paragraph 7.1.2.2.
Component supplier
- Give the vehicle manufacturer the mass of changed interior fittings, for the 8 per cent check in paragraph 7.1.2.2.
Technical service / Approval authority
- As the authority, make the judgement on marked influence on the test results that paragraph 7.1.2.1. asks for.
- Make sure that the Annex 3 test is repeated when paragraph 7.1.2.1. requires it.
- As the Technical Service, define any partial test under paragraph 7.1.2.2.2. in relation to the modifications made.
