Proposal to correct the calculation of the coast-down resistance to progress force.

Proposal to correct the calculation of the coast-down resistance to progress force.

Proposal to define provisions for “Integral” and “Non-Integral” Enhanced Child Restraint Systems (ECRS). “Integral” refers to systems where the child is restrained only by components which comprise the ECRS (e.g. strap harness, impact shield, etc.), and not by means connected directly to the vehicle (e.g. adult seat belt). “Non-Integral”, then, refers to systems where the child is retained by use of the adult seat belt connected directly to the vehicle. This proposal represents “Phase 1” in the development of UN R129.

Proposal to:

• correct the code 19 rim diameter, amend the tyre dimension requirements,
• modify the marking requirements to replace PSI with kilopascals (“kPa”),
• change the measurement units for drum speed from min-1 to km.h-1 and align the wording in Annex 7, Appendix 1 with the text of the Regulation,
• add new tyre sizes to Annex 5, allow for special tyres that can also be used as snow tyres to be marked with the inscription M+S, M.S, or M&S while remaining in the category of use “special”,
• align definitions and content with the other tyre regulations (UN Regulations Nos. 30, 117, 75 etc.),
• include a definition of “manufacturer” extracted from the resolution “R.E.3”
• adopt a common definition and use of the terms “Manufacturer’s name”, “Brand name”, “Trademark”, “Trade description” and “Commercial name” and their links, and
• add information in the certificate to enable approval authorities to more easily understand the products the certificate addresses.

Proposal to align the requirements related to measurement equipment linearity verification in Regulation No. 49 to the provisions in Regulation No. 96.

Proposal to simplify the communication model of approval under UN Regulation No. 115.

Proposal to clarify the test procedure by explicitly excluding first gear where possible from the ASEP control range and to clarify that conditioning of a silencing system is necessary only in cases where exhaust gases come into contact with silencer fibrous materials.

Proposal to

• align the requirements related to measurement equipment linearity verification with the Regulation No. 96,
• adapt the requirements related to fuel injection malfunction monitoring (On-Board Diagnostic systems) to the current state of technology, and
• correct the documentation requirements for off-cycle emissions.

Proposal to limit the use of a booster cushion (booster seat without backrest) with children of a stature greater than 125 cm (i.e., prohibit use of booster cushion for children under 125 cm) and the application for type approval of such CRS only in mass Group III for children of mass from 22 kg to 36 kg and to clarify that a guide strap which constrains the shoulder strap of the adult seat belt in a position to suit the child in a child restraint system cannot be approved as a separate CRS under UN R44.
