UN R26 — 04 series of amendments
Changes from 03 series of amendments (supplement 4)
- What changed
- Paragraph 6.4.1. now says that the wiper holder (head and main part) is designed with a radius of curvature meeting the requirements of paragraph 5.4.
- Paragraph 6.4.2. adds three more wiper parts, if present, to which paragraph 5.4. does not apply.
- New paragraph 6.4.3. says that compliance with paragraphs 6.4.1 and 6.4.2 must be verified with the wipers in parked position.
- Why
- The expert from France prepared the text to clarify requirements in UN Regulation No. 26 on windscreen wipers.
- The proposal clarifies how to deal with potential “exempted” parts and which requirements apply to which part of the windscreen wiper.
- A generic drawing of the concerned areas seems to be the best way for a coherent application together with the requirement wording.
Q1What changed24 changes
Wiper shaft, protective casing and holder (para. 6.4.1.)
Paragraph 6.4.1. now refers to Figure 0 for the wiper shaft (number 1) and the protective casing (number 1.1). The protective casing must still have a radius of curvature meeting paragraph 5.4. and an end surface area of not less than 150 mm2. It now says the holder (head and main part, numbers 2, 2.1 in Figure 0) is designed with a radius of curvature meeting paragraph 5.4.
Wiper parts to which paragraph 5.4. does not apply (para. 6.4.2.)
Paragraph 6.4.2. now says that paragraph 5.4. does not apply to the wiper blades (number 4 in Figure 0). It also does not apply, if present, to supporting members, the second holder and the functional hinge between the holder head and the holder. The same applies, if present, to the junction between the main and the second holder. Before, the paragraph said that paragraph 5.4. does not apply to the wiper blades or to any supporting members. These units must still have no sharp angles or pointed or cutting parts.
New Figure 0: Example of parts distribution
New Figure 0 has the title “Example of parts distribution”. Its legend gives these numbers: 1 Wiper shaft, 1.1 Protective casing, 2 Holder head, 2.1 Main holder, 2.2 Second holder and 3 Supporting members. It also gives 4 Wiper blades, 5 Functional hinge and 6 Junction between the main and second holder. Paragraphs 6.4.1. and 6.4.2. refer to these numbers.
Wipers in parked position (para. 6.4.3.)
New paragraph 6.4.3. says that compliance with the provisions in paragraphs 6.4.1 and 6.4.2 must be verified with the wipers in parked position.
Transitional provisions for the 04 series (paras. 12.8. to 12.11.)
New paragraphs 12.8. to 12.11. set the transitional provisions of the 04 series of amendments for Contracting Parties applying this Regulation. From the official date of entry into force of the 04 series, they must not refuse to grant approval under the 04 series (para. 12.8.). As from 1 September 2022, they need not accept type approvals to the preceding series of amendments, first issued after 1 September 2022 (para. 12.9.). They must continue to accept type approvals issued according to the preceding series of amendments first issued before 1 September 2022 (para. 12.10.). They must not refuse to grant type approvals according to any preceding series of amendments or extensions thereof (para. 12.11.).
Approval marks for the 04 series (Annex 2, Models A and B)
In Annex 2, the text under Model A now refers to the 04 series of amendments, instead of the 03 series. The first two digits of the approval number now indicate that UN Regulation No. 26 already included the 04 series when the approval was granted. The text under Model B now refers to the 04 series for UN Regulation No. 26, instead of the 03 series. For UN Regulation No. 24, it still gives the 03 series of amendments. The figures of the two approval marks also change.

Reasons
The expert from France prepared the text to clarify requirements in UN Regulation No. 26 on windscreen wipers.
Source
“The text reproduced below was prepared by the expert from France to clarify requirements in UN Regulation No. 26 on windscreen wipers.”
Even if road accident data does not allow evaluating this too specific load case for wiper parts, it seems needed to remind the initial objectives. The Regulation aims to reduce the risk or seriousness of bodily injury to persons hit by the bodywork or brushing against it in a collision.
