UN R95 Supplement 3 (05 series) · UNECE Regulation No. 95 (ECE R95) — 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 lateral collision.
UN R95 — Supplement 3 to the 05 series of amendments
Supplement 2 → 3
- What changed
- New paragraph 6.1.2.1. says when a structure or reference mass change requires a repeat of the Annex 4 test.
- Under new paragraph 6.1.2.2., a partial test may be used if the Technical Service considers that modifications are insufficient to warrant a complete retest. The Technical Service considers this after consultation with the vehicle manufacturer.
- Why
- The 05 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 changed2 changes
Repeat of the Annex 4 test after a structure or reference mass change (para. 6.1.2.1.)
New paragraph 6.1.2.1. requires a repetition of the test as described in Annex 4 for “Any modification of the vehicle affecting the general form of the structure of the vehicle or any variation in the reference mass greater than 8 per cent which in the judgement of the authority would have a marked influence on the results of the test”. Paragraph 6.1.2.1. was not in the 05 series before this supplement.
Partial test instead of a complete retest (para. 6.1.2.2.)
New paragraph 6.1.2.2. says: “If the Technical Service, after consultation with the vehicle manufacturer, considers that modifications to a vehicle type are insufficient to warrant a complete retest then a partial test may be used”. The paragraph adds: “This would be the case if the reference mass is not more than 8 per cent different from the original vehicle or the number of front seats is unchanged”. It also says that variations of seat type or interior fittings need not automatically entail a full retest. Annex 8 gives an example of the approach. Paragraph 6.1.2.2. was not in the 05 series before this supplement.
