UN R170 — Supplement 1 to the 00 series of amendments

The Introduction now names Child Restraint Systems (CRS) approved according to UN Regulation No. 129 or UN Regulation No. 44. Such CRS can be used if they can be installed in vehicle seats using the 3-point belt type and/or ISOFIX attachments. The requirements of this UN Regulation do not apply to these CRS. Before, the Introduction named Enhanced Child Restraint Systems (ECRS) approved according to UN Regulation No. 129, and said “belt type” instead of “3-point belt type”.

Paragraphs 4.2.2., 4.2.3., 5.5., 5.6. and 7.3.3. no longer use the word “Enhanced” (or “enhanced”) before “Child Restraint System”. The same applies to paragraphs 8.4.1.7.1.1., 8.4.1.7.3.3.1., 8.4.2.9.1. and 8.4.5.1. It also applies to Annex 8, paragraph 1.

The definitions of “Forward-facing seat” and “Rearward-facing seat” now give the angle as “less than +10° or -10°”. Before, the text said “less than +10° or 10°”. The rest of the two definitions does not change.

Figure 1 now has the title “Labels for a forward- and a rearward-facing child restraint system”. Figure 2 now has the title “Label for a forward-facing child restraint system”. The word “months” should be in a language commonly spoken in the country where the vehicle with the Child Restraint System is registered. Before, the text said “the country or countries”. The minimum label size is now written as “40 mm × 40 mm”.

In paragraph 7.2.1.5., the figure of the strapped-in child is now Figure 3, not Figure 1. Paragraph 8.3.6.6.1. now refers to Figure 4, “Arrangement for testing a forward-facing device”, instead of Figure 2. The examples of arm alignment in paragraph 8.3.7.1.1.9.3. are now in Figure 5, not Figure 3. Table 2 in paragraph 8.3.7.1.1.9.1. now has the heading “Height of the Spacer”. Annex 9 now has Figure 1, “Micro slip test method”. The drawings in Annex 2, Annex 9 and Annex 10, figure 2, example 2, also change.

Annex 3 now has Figure 1, “Child dimension”. New Figure 2 is the “Measurement device for child restraint systems – side and front view of the measuring device”. New Figure 3 is the side and front view of the measuring device for child restraint systems that feature an impact shield. The table now writes “95th percentile” and “5th percentile” instead of “95%ile” and “5%ile”. It also says “Not allowed for these dimensions and stature below 76 cm” instead of “three dimensions”. The mass of the devices is now written as “10 kg ± 1 kg”.

Paragraph 8.1.3.2. now refers to paragraph 8.1.2 for the inspection, instead of paragraph 6.6.1.2. In paragraph 8.4.4.3.6.2.2., the temperature is now “23 °C ± 5 °C” instead of “23 °C + 5 °C”. Annex 6, Appendix 2, paragraph 1.2. has a new footnote on the acceleration (a). The acceleration (a) referring to the centre of gravity is calculated from the triaxial components of the acceleration measured with a CFC of 1 000. The Annex 2 example now refers to the 00 series of amendments, not the “YY” series. The headings of paragraphs 8.3.7.1.1.9.1. and 8.3.7.1.1.9.2. now end with “Child Restraint Systems”.
