UN R118 — Supplement 2 to the 03 series of amendments
Supplement 1 → 2
- What changed
- Paragraph 6.2.8.1. exempts parts made of metal or glass from the tests described in Annexes 6 to 8. It now adds that parts made of plastic glazing are not included in this exemption.
- New paragraph 6.1.9. in Part II defines “plastic glazing”.
- New paragraph 1.1.1. says that, at the request of the manufacturer, this Regulation may also apply to vehicles of Categories M3, Class I.
- Why
- The proposal aims at clarifying that parts made of plastic glazing are required to undergo the tests described in Annexes 6 to 8.
- The expert from OICA suggested additions to introduce M3 class I vehicles into the current scope of UN Regulation No. 118, on a voluntary basis.
Q1What changed3 changes
Plastic glazing and the exemption for parts made of metal or glass (paras. 6.1.9. and 6.2.8.1.)
Under paragraph 6.2.8., parts made of metal or glass are not required to undergo the tests described in Annexes 6 to 8. Paragraph 6.2.8.1. now adds that parts made of plastic glazing are not included in this exemption. In Part II, new paragraph 6.1.9. defines “plastic glazing” as “a glazing material that contains as an essential ingredient one or more organic polymeric substances of large molecular weight”. The definition also says that the material “is solid in its finished state and, at some stage in its manufacture of processing into finished articles, can be shaped by flow”.
Vehicles of Categories M3, Class I at the request of the manufacturer (para. 1.1.1.)
New paragraph 1.1.1. says that, at the request of the manufacturer, this Regulation may also apply to vehicles of Categories M3, Class I.
Q2Why it changed

- GRSG, 121st session (April 2021)
Reasons
The proposal aims at clarifying that parts made of plastic glazing are required to undergo the tests described in Annexes 6 to 8. Parts made of metallic and glass elements are exempted because these materials are not affected by the tests according to Annexes 6 to 8. This behaviour (fire resistance) is not present at plastic materials used in many parts inside the vehicles. So parts made of plastic glazing should not be affected by the exemption and should be tested. The clarification is to avoid misinterpretations that could lead to exemptions and a risk of safety. The definition of plastic glazing in UN Regulation 43 is added to Part II to define precisely the materials not covered by paragraph 6.2.8.

“aims at clarifying that parts made of plastic glazing are required to undergo the tests described in Annexes 6 to 8 of the Regulation 118”
“The reason for the exemption to the parts made of metallic and glass elements is that these materials are not affected by the tests according to the Annexes 6 to 8 of UN Regulation No. 118.”
“This behaviour (fire resistance) is not present at plastic materials used in many parts installed inside the vehicles.”
“Accordingly, parts made of plastic glazing should not be affected by the exemption of para. 6.2.8., and therefore, these materials should be tested.”
“The clarification is proposed to be included inside the UN Regulation No. 118 to avoid misinterpretations that could lead to exemptions, and therefore constitute a risk of safety.”
“It is also proposed to include, at Part II of UN Regulation 118, the definition of plastic glazing made at UN Regulation 43 in order to define precisely the materials not covered by para 6.2.8.”
The expert from OICA suggested additions to introduce M3 class I vehicles into the current scope of UN Regulation No. 118, on a voluntary basis.

Proposer's reason (informal document GRSG-121-04)
The proposal states that it will measurably improve fire safety for class I busses (used in suburban traffic).

“This proposal will measurably improve fire safety for class I busses (used in suburban traffic)”
Proposer's reason (informal document GRSG-121-04)
The UN R118 type approval certificate for class I is frequently considered as a criterion in city bus tender processes. The proposal states that it will secure that there are no different interpretations among approval authorities. It states that the proposal will therefore secure no unequal treatment of the request of vehicle manufacturers, especially in case of tenders.

Proposer's reason (informal document GRSG-121-04)
The proposal states that the modification will not imply any technical change for the manufacturers not interested in the certification of class I busses.
